UiPath API Workflow Assistant
Build, run, and publish UiPath API Workflows — JSON files conforming to the CNCF Serverless Workflow DSL 1.0.0 with UiPath activity-type extensions. Executed by @uipath/api-workflow-executor via uip api-workflow run. Packaged as Type: "Api" projects via uip solution pack.
TDD gate — read this first (rule 22). On ANY request to create or edit a workflow, Phase 0 first checks whether the project has an evals/ folder — it lives inside the project directory, next to Workflow.json (<project>/evals/), not at the workspace or solution root, so list the project directory itself. No evals/ folder → the Evaluations feature is not enabled for this project: skip everything about tests and loop mode and author normally. evals/ present → end your turn with two questions — (1) tests: the eval set has rows → "should anything change, or use as-is?" / it is empty → "want me to add some?"; (2) loop mode: "run the tests and re-try until every case passes, or author once?" — and NOTHING is authored until the user answers. Tests come first: once answered, write or update the eval set, then author the workflow to make it pass. If you are about to write Workflow.json in a project with evals/ and the user has not answered these two questions in this conversation, stop. Later change requests that alter behavior can break the tests — ask before editing whether to update them (rule 22, references/testing-and-evals.md §3). Only a prompt that explicitly says not to ask skips the gate when evals/ exists — and that skips the questions, not the run consent (rule 21): run rows only when the request itself asks for a run.
When to Use This Skill
- User wants to create or edit an API workflow JSON file
- User wants to run an API workflow locally with
uip api-workflow run
- User wants to package an API workflow project into
.nupkg / solution .zip
- User wants to publish an API workflow to UiPath Cloud / Orchestrator
- User asks about activity types (Sequence, Assign, JavaScript, If, ForEach, DoWhile, Break, TryCatch, Wait, Response, HTTP Request, Connector)
- User asks about nested control flow — If inside ForEach, TryCatch around a loop, conditional Break, multi-way branching, etc.
- User asks for an Integration Service connector activity (Gmail Send Email, Outlook Get Newest Email, GitHub Search Issues, Slack Send Message, etc.) — follow the discovery flow in references/connector-activity-discovery.md
- User asks for a generic HTTP Request that needs to render in StudioWeb's designer — same discovery flow
- User asks about JavaScript expressions,
$context, $input, $workflow, WorkflowStart, or the export.as pattern
- User asks how to debug a failing API workflow run — the local
validate → run --no-auth loop, or a post-publish cloud run (job logs/traces). See references/operating-published-workflows.md
- User wants to operate a published workflow — invoke it (HTTP/schedule/Integration Service event trigger), start/list/stop its Orchestrator jobs, or manage the Integration Service connections it uses (
uip is connections list/ping/edit). See references/operating-published-workflows.md
- User wants to test / evaluate a workflow — author
(inputs, expectedOutput) cases in the project's evals/ folder (the dataset Studio Web's Evaluations panel reads), run them, score them by the project's evaluator, or "loop until the tests pass". Follow references/testing-and-evals.md. An evals/ folder alone is not the signal — it is an API-workflow one only when it sits next to Workflow.json and uses the evals/<scope>/eval-sets/ layout; low-code agents use evals/eval-sets/ (no scope) → uipath-agents, Flow evals → uipath-maestro-flow
- Any authoring request (create or edit) — Phase 0 discovery checks for an
evals/ folder; when it exists, the two test questions (change / add tests? loop mode?) are asked up front — the turn ends there — whether or not the user mentioned testing (rule 22). No evals/ folder → the feature is off, author normally. See Phase 0 and references/testing-and-evals.md
Do NOT use for: .flow Maestro flows (→ uipath-maestro-flow), .xaml / coded RPA (→ uipath-rpa), coded agents (→ uipath-agents), Coded Web Apps (→ uipath-coded-apps).
Core Principles
- Tests first — when the project has
evals/, and only after asking. Discover <project>/evals/ (next to Workflow.json). Absent → the Evaluations feature is off for this project: author normally, no test or loop-mode questions. Present → ask the two rule-22 questions, end the turn; once answered: declare output.schema, eval set first, workflow second, then run the rows only in loop mode (that "yes" is the rule-21 consent; "author once" means hand over without running). Behavior changes later on re-open the question — the tests may need updating.
- Know before you write. Read the existing workflow file before editing. Read an example template before creating from scratch.
- Start minimal, iterate to correct. Add one activity at a time. Run with
--no-auth --output json after each addition. Fix what breaks. Repeat.
- Validate before running.
uip api-workflow validate is the offline static pre-flight (autonomous); uip api-workflow run is the runtime validator that catches what static analysis can't (live HTTP, expression evaluation, connection state) and needs user consent. See rules 20–21.
- Fix errors by category. Triage: Structure > Expression > Activity Config > Logic. Higher-category fixes often resolve lower-category errors automatically.
Critical Rules
Rule 0 — Escalate big design forks before you build (highest priority, read first). When the happy path doesn't work out of the box and the resolution is a judgment call the user would reasonably want to own, STOP and ask before committing to a branch. Present the concrete options with their trade-offs and a recommended default; proceed only on the user's answer. Triggers (non-exhaustive): no valid connection for a required activity (rule 16); no curated activity exists and the choice is generic activity vs. raw Http kind vs. a different connector; the requested operation isn't exposed by any resolvable activity and the fallback is a hand-built HTTP call against an undocumented endpoint; an input the prompt assumed is missing and the alternatives are placeholder, hardcoded value, or new workflow input; the prompt is satisfiable by structurally different workflows (single connector call vs. ForEach over a list). This does NOT cover mechanical choices with an obvious answer (variable names, activity key suffixes, export-pattern selection) — decide those and move on. Reserve escalation for forks where guessing wrong wastes work or ships something the user didn't intend.
Ask the fork BEFORE branch-specific research, not after. Once you spot a structural fork, do only the shared work needed to surface the options (the cheap resolve that proves no curated activity exists, the connections list/ping that proves no connection works), then ask. Do NOT pre-research every branch — stubbing each candidate activity, describing resources, drafting alternative workflow shapes — so the user can "pick from finished work." The user picks one branch; deep work on the others is thrown away. Sequence: detect fork → minimal shared discovery → ask → then research and build only the chosen branch.
- Workflow file is JSON, not YAML. Top-level keys:
document (with dsl: "1.0.0"), evaluate (language: "javascript", mode: "strict"), do (one root sequence — named Sequence_1 in the template skeleton, but the literal key may differ in existing workflows; always read the actual key from the file before editing — containing WorkflowStart + user activities). See references/workflow-file-format.md.
WorkflowStart is always the first activity inside the root sequence's do array. It hydrates variable defaults into $context.variables and forwards inputs to $input. Never remove, rename, or modify it. isTransparent: true (only WorkflowStart uses true).
- Every activity is a single-key object wrapped in the
do array: { "<ActivityKey>": { ...activity body... } }. Activity keys must be globally unique across the whole workflow — including #Wrapper, #Then, #Else, #Body suffixes.
- Every activity should
export its output to propagate state. Two patterns:
- Variables (Assign only):
{ ...$context, variables: { ...$context.variables, ...$output } }
- Outputs (everything else):
{ ...$context, outputs: { ...$context?.outputs, "<ActivityKey>": $output } }
See references/expressions-and-context.md.
- String literals in
Assign.set / Response / If when MUST be wrapped as "${'literal'}" — a JS string inside an expression. Plain "literal" runs fine under uip api-workflow run, but StudioWeb's designer normalizes unwrapped values to "${literal}" on save (treating them as expressions you typed into the property panel). At runtime the bare identifier literal has no binding → ReferenceError: literal is not defined. Use single quotes inside the expression to avoid JSON escaping: "set": { "tier": "${'PLATINUM'}" }. Numbers, booleans, and references like ${$context.variables.X} need no extra wrapping. (Response payloads have a related but distinct constraint — see rule 15.) Scope: this rule applies to Assign / Response / If / variable contexts only. It does NOT apply to connector bodyParameters / queryParameters / pathParameters — those take BARE literals; ${'...'} there is read as an expression and the field is cleared on save. See rule 16 and references/connector-activity-discovery.md#field-shape-rules-flat-keys-bare-literals-renamed-export-hub-prefix. See references/troubleshooting.md.
- Each
Assign activity MUST set exactly ONE variable. Assign.set is a single-key object, NOT a multi-variable update. StudioWeb's designer collapses multi-key set blocks to one key on save, silently dropping the others — the runtime then only updates the surviving key. To update N variables, use N separate Assign activities placed sequentially in the same do array. Example: instead of "set": { "sum": "${$context.variables.sum + 1}", "count": "${$context.variables.count + 1}" } (loses count after StudioWeb save), write two Assigns — Assign_Sum with "set": { "sum": "${...}" } and Assign_Count with "set": { "count": "${...}" }. Each runs in order; each Assign's variables export merges its single key into $context.variables.
- If activity requires the wrapper pattern.
If_N#Wrapper contains If_N (switch), If_N#Then, If_N#Else. Both #Then and #Else MUST end with "then": "exit" to prevent fall-through. Conditions in when MUST be wrapped in ${...}. For deeply-nested If patterns and multi-way branching, see references/control-flow-patterns.md.
- Loops (ForEach, DoWhile) require a
#Body element inside do. ForEach body uses index-aware accumulation (resets on iteration 0); DoWhile body uses simple accumulation. Loop variables (each, at) are plain strings, NOT expressions.
- DoWhile
for.in is always "${ [1] }". The doWhile condition controls repetition. The body MUST update the condition variable, otherwise the loop runs forever.
- Nested loops MUST use distinct iterator/index names. Outer
for.each: "outerItem", inner for.each: "innerItem". Reusing currentItem shadows the outer. "Distinct" just means "not the same string" — semantic (outerItem / innerItem) and incremental (item1 / , / ) naming both work.
- **On-disk is authoritative.** Even with the single-expression workaround, every StudioWeb designer save can re-trigger normalization passes that may corrupt the Response shape. After any designer roundtrip, re-validate with `uip api-workflow run --no-auth` and re-apply the workaround if needed. Until the designer fix ships, treat the file on disk as truth, not what the designer renders.
- Connector activities (HTTP + Integration Service) come from
uip api-workflow registry resolve + stub — never hand-author or guess. The stub computes metadata.configuration, the kind (UiPath.Http vs UiPath.IntSvc), the endpoint (with hub prefix), SlotKey, and ExportBucketKey (which can differ — HTTP slot HttpRequest_1 vs bucket http_request_1). Use all of them verbatim; NEVER invent a uiPathActivityTypeId, hand-author metadata.configuration, or reconstruct a key from objectName. Non-negotiables (full step-by-step, field-shape rules, multipart, and worked examples in references/connector-activity-discovery.md):
- A keyword
resolve miss is NOT proof no curated activity exists — verify connector-first before giving up. resolve AND-matches every token, so a marketing phrase + guessed verb over-narrows (the product "UiPath Data Fabric" carries connectorKey: uipath-uipath-dataservice and activity names like "Create Entity Record" — resolve "data fabric insert" returns 0; fewer/truer tokens, not more). Before concluding none exists or falling back to a hand-built HTTP call (a Rule 0 fork): map the product/vendor → connector key with uip is connectors list --filter "<product>", then enumerate with uip is activities list <connector-key>. Do NOT hardcode/guess the key — look it up. See the reference's Step 1 recovery.
- IntSvc/vendor activities require a pinged connection.
uip is connections ping <uuid> must succeed before authoring — listing-state ≠ runtime-state; an Enabled connection can still 401 in cloud. An empty listing is NOT proof no connection exists — uip is connections list is folder-scoped. On empty/failed listing, walk the fallbacks in order: unfiltered uip is connections list, then uip is connections list --all-folders (catches connections in other folders), re-pinging a different Id for that ConnectorKey each time.
- No connection pings cleanly → STOP and ask the user — do not decide alone. Offer: (a) continue with a placeholder (stub without , leaving the sentinel — workflow is structurally complete but 401s until replaced; only with explicit user consent), or stop and wait for the user to create/fix the connection, then re-ping. Never silently emit the placeholder, never silently abort. (Instance of Rule 0 — escalate design forks.)
- **(Solutions-mode + IntSvc only)** sync the connection into the catalogue: `uip api-workflow bindings sync --workflow <Workflow.json>` then `uip solution resource refresh --solution-folder <path>`. Skip for Http kind, non-connector activities, and standalone (no `Solution/`) projects.
- Pass input as a JSON string.
--input-arguments '{"key":"value"}'. Invalid JSON exits 1.
- Always
--output json when parsing CLI output programmatically. Success → { "Result": "Success", "Code": "WorkflowRun", "Data": {...} }. Failure → { "Result": "Failure", "Message": "...", "Instructions": "..." } with exit 1.
- Scaffold with
uip api-workflow init; publish goes through the solution packager. Create every API workflow project with uip api-workflow init <name> (rule 19a) — never hand-assemble the project files. Project-level CLI commands also exist: uip api-workflow build <projectDir> (compile) and uip api-workflow pack <projectDir> <outputDir> (single-project .nupkg, useful to test one project in isolation). Solution-level build/publish go through uip solution pack <solutionDir> <outputDir> + uip solution publish <package.zip>. There is NO uip api-workflow publish command. Project type must be "Api" in the solution .uipx.
19a. Create projects with uip api-workflow init <name> — it produces the correct Studio Web editable shape and wires the solution. Run it from inside the solution directory (the folder containing the .uipx):
bash uip api-workflow init <name> --output json # add --skip-solution-registration for a standalone (no .uipx) project
It scaffolds project.uiproj + Workflow.json + entry-points.json + bindings_v2.json and, when run inside a solution, auto-registers the project in the surrounding .uipx (correct ProjectRelativePath + a fresh Id). Success → Code: "ApiWorkflowInit". Then edit Workflow.json only.
**Which mode.** Default = `init` inside a solution (Studio Web-editable + deployable — what a shipped automation needs). Use `--skip-solution-registration` ONLY when the user explicitly wants a CLI-only/local workflow that never opens in Studio Web or ships in a solution; it still emits the full project folder (`<name>/Workflow.json` + siblings), just no `.uipx` wiring. Never emit a lone `Workflow.json` with no project files — even a throwaway local workflow gets a project.
**Why it matters:** a legacy `project.json` + `workflows/WF_*.json` layout (no `.uiproj`) passes every runtime gate — `validate`, `run`, `pack`, `publish`, deploy — but Studio Web rejects it as `invalid_project_folder` and never shows it. `init` is the one step that can't produce the wrong shape. Full layout + field rules: [references/workflow-file-format.md](references/workflow-file-format.md#project-structure-studio-web-editable-contract).
To **convert a legacy `project.json` project**, `init` a fresh sibling and move the existing workflow content into its `Workflow.json` (cleanest), or convert in place — see [references/troubleshooting.md](references/troubleshooting.md). Never wire it with `uip solution projects add/remove` (errors on an already-registered name; `remove`+`add` destroys the project `Id`).
-
uip api-workflow validate <Workflow.json> is the autonomous closure step for every authoring or edit cycle. Run it as the LAST command before asking the user anything about runtime. It's offline (no auth, no network, no side effects): JSON Schema + semantic checks on the static file. Output codes:
Result: "Success", Code: "ApiwfValidate", Data.Status: "Valid" (exit 0) — possibly with Data.Warnings. Proceed to rule 21 (ask the user whether to run).
Result: "Failure" (exit 1) — do NOT bother the user. Read Instructions, locate the offending activity by its JSON path (e.g. /do/0/Sequence_1/do/2/Mystery_1/metadata/activityType), edit Workflow.json to fix it, then re-validate. Loop until pass.
Reading the error list. AJV schema errors from oneOf branches produce duplicate "Missing required property" noise (each unmatched variant lists all its required fields). Focus on the semantic-tail errors — the ones with prose messages like Unknown activityType 'X', must contain a 'do' with inner 'switch', is missing 'metadata.configuration', Variable must have a non-empty 'type'. Those uniquely identify the root cause. Fix one root cause, re-validate, repeat — don't chase the schema-level fanout one by one.
**What validate catches:** malformed JSON; unknown `activityType` values (see VALID_ACTIVITY_TYPES list in the validate source); per-activity required keys (If → `do` + inner `switch`, Sequence → `do`, Assign → `set`, ForEach → `for` + `do`, DoWhile → `for` + `doWhile`, Connector → `call` + `metadata.configuration` + `essentialConfiguration`, Response → `response`, etc.); missing `metadata.activityType`/`displayName` (warnings); bad `evaluate.language`/`evaluate.mode`; duplicate or empty-named workflow variables; empty task lists. **What it does NOT catch:** wrong `selectedResourceId`, broken connector connection IDs, runtime expression errors (`ReferenceError: x is not defined`), unwrapped string literals (rule 5), multi-key `Assign.set` (rule 6) — those still need runtime validation via `uip api-workflow run` once the user consents.
- Never run
uip api-workflow run without an explicit user "yes." Validation (rule 20) is autonomous; running is not. Once validate passes, ask the user: (a) run now or skip, (b) if running, with --no-auth (fast, structure-only — IntSvc kind vendor calls fail) or with auth (real Integration Service calls — vendor side effects WILL happen: emails sent, tickets created, files uploaded). Suggest a default based on workflow content (--no-auth for control-flow-only + Http kind ImplicitConnection; with-auth for any IntSvc kind vendor activity), but wait for the user's answer. Never invoke uip api-workflow run with auth on speculation — once a vendor call goes out, it can't be unsent.
-
TDD gate — only for projects with an evals/ folder; STOP and ask before authoring; tests are written before the workflow. Every authoring request (create OR edit — including a one-line change) runs Phase-0 discovery of the project's evals/ folder — <project>/evals/, the directory next to Workflow.json (list that directory; the workspace or solution root is the wrong place to look):
- No
evals/ folder → the Evaluations feature is not enabled for this project. Skip the gate entirely: do not offer to create tests, do not mention loop mode, do not create the folder — author normally (Phases 1–3).
evals/ present → end the turn with two questions. Do not write or edit Workflow.json, and do not create or change eval files, until the user has answered both:
- Tests — the eval set has rows → "I found N test case(s): [one line each]. Should anything change, or use them as-is?"; the set is empty (the panel seeds one with 0 rows) → "There are no test cases yet — want me to add some? I'd suggest: [2–3 proposed cases]."
- Loop mode — "Run in loop mode (run the tests and re-try — fix, re-run — until every case passes), or author once and you verify?" A "yes" to loop mode is also the consent to run the rows with
--no-auth (rule 21) — do not ask "run now?" separately; connector/authed runs still need their own explicit "yes".
Order after the answers (TDD): first declare input.schema / output.schema in Workflow.json (init scaffolds output: null, so the row keys have no other source — property names and casing come from here, and the Response must emit exactly those keys), then write or update the eval set, then author the workflow, then run the rows (loop mode) or hand over (author once — do not run). Later change requests that alter behavior (threshold, rounding, branch order, a new default — even with the schema unchanged) can make existing expectations wrong: before editing, list the affected rows and ask whether to update them; after editing, re-run the rows. Ask as two specific questions — never one vague "how do you want to verify it?". With evals/ present, the gate is skipped only when the user already answered, or explicitly asked not to be prompted ("don't ask for confirmation"); then keep existing tests as-is and add tests only if requested. "Don't ask" waives the two questions, rule 21's run consent: run the rows only if the request itself asks for a run or a loop ("run the evaluations", "until they pass" — that wording is the consent); otherwise author once and hand over the exact command to run them. Protocol and wording: §3.
Workflow Phases
Phase 0: Discovery
Before touching anything, understand what exists — the workflow structure and whether the project has tests. Discovery ALWAYS includes checking for an evals/ folder inside the project directory (ls <project>/ — the folder is a sibling of Workflow.json, never at the workspace/solution root): Studio Web creates it when the Evaluations feature is enabled and the panel is opened, so its absence means the feature is off for this project. If present, read evals/<scope>/eval-sets/*.json (<scope> is default unless the project says otherwise) and the evaluator(s) in evals/<scope>/evaluators/ — the same files the Evaluations panel reads and writes. Contract and semantics: references/testing-and-evals.md §1.
Then apply rule 22 (TDD gate): no evals/ folder → the feature is off, continue to Phase 1 without any test or loop-mode question; evals/ present → end the turn with the two questions — tests (change / add?) and loop mode — and start Phase 1 only after the user has answered, writing the eval set before the workflow.
For edit requests:
- Read the existing workflow file with
Read
- Identify activity keys already in use (avoid collisions)
- Identify variables, inputs, outputs already declared
- Identify export patterns in use (stay consistent)
For create requests:
- Read assets/templates/api-workflow-template.json for the empty skeleton
- Read a closer example based on need:
- For nested patterns specifically, read references/control-flow-patterns.md — pattern catalog for If-in-If, ForEach-with-If, TryCatch-around-loop, conditional Break, etc.
Phase 1: Plan
Decide which activities to use and in what order.
| User wants | Activity type | Key points |
|---|
| Set/transform variables | Assign | Sets $context.variables; uses variables export pattern |
| Run custom logic | JavaScript (JsInvoke) | Inline JS; access context via $context / $workflow / $input globals (NOT arguments[0]) |
| Branch on condition (2-way) | If | #Wrapper + #Then + #Else structure required |
| Branch on condition (3+ way) | Chain of Ifs | Each #Else holds the next If — see control-flow-patterns.md |
| Iterate over collection | ForEach | for.each/for.in/for.at; needs #Body |
| Repeat until condition | DoWhile | for.in: "${ [1] }"; needs #Body; must update condition variable |
| Handle errors (whole batch) | TryCatch around loop | One bad item kills the batch — see control-flow-patterns.md |
| Handle errors (skip & continue) | TryCatch inside body | One bad item skipped, loop continues — see control-flow-patterns.md |
| Return result and end | Response | then: "end"; markJobAsFailed sibling of response |
| Pause execution | Wait | wait.seconds// |
Before generating, determine:
- Which activities are needed and in what order
- What unique keys to assign (check existing keys to avoid collision)
- What variables to declare (in
document.metadata.variables.schema.document.properties)
- What inputs/outputs to declare (in
input.schema / output.schema)
Phase 2: Generate or Edit
Precondition (projects with evals/): the two rule-22 questions have been answered in this conversation and the eval set (if wanted) is already written. If not, go back to Phase 0 and ask — do not write Workflow.json yet. Projects without evals/ have no such gate.
For each activity, read its reference section in references/task-types.md, copy the minimal JSON, fill in values.
For CREATE: copy from a template, then add user activities AFTER WorkflowStart inside the root sequence (literally Sequence_1.do in the template skeleton).
For EDIT: read the file first, identify the exact insertion / replacement point, use Edit with sufficient context for unique matching.
If the edit changes behavior and the project has an eval set, rule 22 applies first: ask whether to update the expectations the change would invalidate, then edit, then re-run the rows (see references/testing-and-evals.md §3 step 5).
Workflow skeleton:
{
"document": { "dsl": "1.0.0", "name": "...", "version": "0.0.1", "namespace": "default", "metadata": { "variables": { "schema": { "format": "json", "document": { "type": "object", "properties": {...}, "title": "Variables" } } } } },
"input": { "schema": { "format": "json", "document": { "type": "object", "properties": {...}, "title": "Inputs" } } },
"output": { "schema": { "format": "json", "document": { "type": "object", "properties": {...}, "title": "Outputs" } } },
"do": [{ "Sequence_1": { "do": [ { "WorkflowStart": { /* system */ } }, /* user activities */ ], "metadata": {...} } }],
"evaluate": { "mode": "strict", "language": "javascript" }
}
Phase 3: Validate (static) then Run (with consent)
Validate autonomously (rule 20), fixing + re-validating until Data.Status: "Valid":
uip api-workflow validate ./my-workflow.json --output json
Once green, ask before running (rule 21) — pick the mode from workflow content:
| Mode | Flag | What happens | Use when |
|---|
| No-auth | --no-auth | Skips token loading. Structure / expressions / control flow validated. IntSvc vendor calls fail with a missing-token error. | Control-flow-only, OR Http kind with connectionId: "ImplicitConnection". Default for most iterations. |
| With auth | (none) | Uses the uip login token. Real Integration Service calls — vendor side effects happen. | An IntSvc vendor activity AND the user confirmed the real call is OK (email sent, ticket created, file uploaded). |
State the consequence in the question (e.g. "running with auth WILL send a real email to <recipient> — (1) skip, (2) --no-auth, (3) run with auth?"), wait for the reply, then run uip api-workflow run ./my-workflow.json [--no-auth] --output json. If the user skips, give them the exact command and stop.
Fix run failures in category order — Structure > Expression > Activity Config > Logic (higher categories often resolve lower ones). Full pitfall catalog: references/troubleshooting.md.
Phase 4: Package, Publish, and Operate
Once the workflow runs locally, deploy via the solution packager. If the project must open in Studio Web, confirm it uses the init-produced shape first (rule 19a) — runtime/pack success does not prove it.
Pack:
uip solution pack <solutionDir> <outputDir> \
--name <PACKAGE_NAME> \
--version 1.0.0 \
--output json
The packager auto-detects Type: "Api" projects, validates structure, copies workflow files, generates operate.json + package-descriptor.json, and produces a .nupkg wrapped in a .zip.
Publish:
uip solution publish <outputDir>/<package>.zip \
--tenant <TENANT_NAME> \
--output json
Requires uip login.
Operate + diagnose the published workflow. Once deployed, the workflow is an Orchestrator API process — the local uip api-workflow verbs no longer apply to it. Invoke it (HTTP/schedule/Integration Service event trigger), start/list/stop its jobs, manage the Integration Service connections it uses, and read cloud-run logs/traces via uip or / uip is / uip traces. Full command map: references/operating-published-workflows.md. These are sibling-skill surfaces (uipath-platform, uipath-troubleshoot) — delegate there for depth.
Quick Start (CREATE from scratch)
# 0. Create the solution (skip if one already exists). Creates ./MySolution/ with the .uipx.
uip solution init MySolution --output json
# 1. Scaffold the project — correct Studio Web shape + auto-registers in the .uipx (rule 19a).
# init's <name> arg takes no slashes, so cd into the solution dir first; it registers the
# project in the nearest parent .uipx. Creates MyApiProject/ with project.uiproj,
# Workflow.json, entry-points.json, bindings_v2.json.
cd ./MySolution
uip api-workflow init MyApiProject --output json
# 1b. TDD gate (rule 22): if ./MyApiProject/evals/ exists (next to Workflow.json), STOP and ask the two questions
# (tests: change / add? loop mode?) and wait for the answers before step 2.
# No evals/ folder → the feature is off for this project; go straight to step 2.
# 2. Edit MyApiProject/Workflow.json to add user activities after WorkflowStart inside the root sequence
# 3. Validate (offline, autonomous — fix + re-validate until Status: Valid)
uip api-workflow validate ./MyApiProject/Workflow.json --output json
# 4. Ask the user, then run (only on user "yes")

Reference Navigation
| File | Use when |
|---|
| references/workflow-file-format.md | Authoring or editing the JSON skeleton: top-level keys, document.metadata.variables schema, input.schema/output.schema, WorkflowStart |
| references/http-retry-config.md | Adding workflow-level HTTP retry policy (httpRetryConfig) — scope (GET-only), constant/linear/exponential backoff formulas, defaults, Retry-After handling, anti-patterns |
| references/task-types.md | Adding/editing any single activity — exact JSON shape, required fields, export pattern, common mistakes, basic nesting hints per type |
| references/control-flow-patterns.md | Combining activities into hierarchical structures — nested If, ForEach inside DoWhile, TryCatch around/inside loops, conditional Break, multi-way branching, key uniqueness rules |
| references/connector-activity-discovery.md | Authoring HTTP Request / Gmail / Outlook / GitHub / Slack / etc. activities via uip api-workflow registry resolve + stub — three-step flow, sample stub output, field-shape rules, multipart subsection, worked examples |
| references/expressions-and-context.md | Writing JS expressions, propagating outputs via export.as, accessing $context / $input / $workflow, JS_Invoke argument passing, strict-mode gotchas, key patterns |
| references/cli-reference.md | All uip commands — api-workflow init, run, build, pack, validate, solution init, solution pack, solution publish, login |
| references/operating-published-workflows.md | Operating + diagnosing a published workflow — invoke via HTTP/schedule/event triggers, manage Integration Service connections (uip is connections), start/list/stop Orchestrator jobs (uip or jobs), diagnose a faulted cloud run (uip or jobs get — jobs logs and traces spans get are dead ends here). Delegates depth to uipath-platform / uipath-troubleshoot |
| references/troubleshooting.md | Failed runs, structure/expression/loop/nesting/response/validation pitfalls, packaging errors, publish errors, debugging strategy |
| references/testing-and-evals.md | Testing / evals — the evals/<scope>/eval-sets + evaluators file contract shared with Studio Web's Evaluations panel, uipath-exact-match scoring (strict deep-equal on the RAW output — the CLI PascalCases printed keys), running a row locally with --no-auth (or through the host in Studio Web), and the interactive test-until-green loop (offer → check evals/ → create/update cases → run/fix/repeat with progress → stale-expectation guard) |
Templates
| assets/templates/connector-call-example.json | Http kind — HTTP Request curated activity (call: "UiPath.Http") for arbitrary REST calls. Generated by registry stub against the catfacts URL. Shows the canonical shape: connectionId: "ImplicitConnection", unifiedTypesCompatible: true, savedJitInputFieldId: "in_http-request", URL in bodyParameters.url. Verified end-to-end with uip api-workflow run --no-auth. |
| assets/templates/vendor-curated-call-example.json | IntSvc kind — vendor curated activity (call: "UiPath.IntSvc") using Outlook GetNewestEmail as exemplar. The <REPLACE_WITH_VENDOR_CONNECTION_UUID> placeholder is a sentinel — replace it with a pinged UUID from uip is connections list/ping before writing the workflow to disk. StudioWeb renders the literal placeholder as a broken connection if it survives. See rule 16. |
| assets/templates/solution-connection-resource-template.json | Solution connection resource — declares a IntSvc kind connection as a Solution resource. Write to Solution/resources/solution_folder/connection/<connector-key>/<connection-name>.json. Required for Solutions-mode projects; without it the StudioWeb properties panel flags the activity as having an invalid connection. |
Anti-patterns
The mistakes an agent makes most often (each maps to a Critical Rule above — see it for the full reasoning):
- Do NOT use
call: "http" for a REST call — it's the training-data default, but StudioWeb rejects it (renders as a "block" icon). Use call: "UiPath.Http" from registry stub. See rule 16.
- Do NOT wrap connector
bodyParameters / queryParameters literals as ${'literal'} — rule 5's wrap is inverted for connectors; bare literals only, or the field clears on save. See rule 16.
- Do NOT ship a
<REPLACE_WITH_*> placeholder in a workflow — StudioWeb renders it as a broken connection and it 401s. No pinged UUID → ask the user. See rule 16.
- Do NOT read workflow inputs as
$input.<name> from a non-first activity — use $workflow.input.<name>. See rule 13.
- Do NOT invoke
uip api-workflow run autonomously, and never with auth without an explicit "yes" — vendor calls have irreversible side effects (emails sent, tickets created). See rules 20–21.
- Do NOT hand-assemble a project (
project.json + main.json/workflows/WF_*.json). Scaffold with uip api-workflow init <name> — it writes the correct project.uiproj shape and registers it in the .uipx. The legacy project.json-only shape runs and packs but Studio Web rejects it (invalid_project_folder) and never shows it. See rules 19–19a.
- Do NOT emit a lone
Workflow.json with no project files, even for a quick local run. It runs under uip api-workflow run but is not a Studio Web project — can't be edited or shipped. Every workflow lives in an init-scaffolded project (--skip-solution-registration when no solution is needed). See rule 19a ("Which mode").
- Do NOT wire a project into the solution with
uip solution projects add/remove — it errors on an already-registered name, and remove+add destroys the project Id. init registers it; for an already-built project, edit the .uipx ProjectRelativePath in place. See rule 19a.
- Do NOT trust "it packed / published / ran" as proof a project opens in Studio Web — every runtime gate passes on the wrong shape. Scaffolding with
init is what guarantees it (rule 19a).
- Do NOT copy expected outputs from the CLI's printed
Data — uip PascalCases every key (grade → Grade) and uipath-exact-match is case-sensitive on keys, so the row passes for you and fails in the Evaluations panel. Derive keys from output.schema / the Response expression and read the raw output from the debug log. See references/testing-and-evals.md §2.
- Do NOT author first and ask later in a project that has
evals/: rule 22 ends the turn with the two test questions (change / add tests? loop mode?) BEFORE any Workflow.json or eval file is written, unless the user already answered or asked not to be prompted. Do NOT offer tests or loop mode — or create an evals/ folder — in a project that has none: the feature is not enabled there. And do NOT "fix" the workflow to satisfy an expectation a requested behavior change made stale — re-derive the expected outputs instead, after asking. See rule 22 + references/testing-and-evals.md §3–4.
Infinite Loop Prevention
If a CLI command fails with the same error 2+ times, do NOT retry it. Investigate the root cause:
Not authenticated / Organization ID not available → ask the user to uip login, do not retry
File not found → check the path with ls
- Repeated structural errors after fixes → re-read the workflow and the relevant reference section; you may be misreading the file
Maximum 3 attempts for any single operation. After 3 failures, stop and report what was tried.
