| description | Use the One CLI (`one`) to interact with 3rd-party platforms — Gmail, Slack, Stripe, Notion, etc. through their APIs. One handles auth, request building, and execution.
TRIGGER when:
- Interact with ANY 3rd-party platform or external service (e.g., "send an email", "create a Shopify order", "find a HubSpot contact", "post to Slack")
- List their connected platforms or check available ones
- Search for available actions (e.g., "what can I do with Gmail")
- Execute API calls with a connected platform
- Set up webhook-driven automations between platforms (e.g., "when a Stripe payment comes in, notify Slack")
- Build multi-step workflows that chain actions across platforms (e.g., "fetch Stripe customers and email each one")
- Anything involving 3rd-party APIs, integrations, or connected apps — even if they don't mention "One" by name
DO NOT TRIGGER for:
- Setting up One or installing MCP (use `one init`)
- Adding new connections (use `one add <platform>`)
- Configuring access control (use `one config`)

One CLI
You have access to the One CLI which lets you interact with 600+ third-party platforms through their APIs. Always include the --agent flag right after one for structured JSON output.
If the user wants a separate API key / connections for a specific project (vs. their default), walk them through running one init from that project folder and picking the "project" scope — see references/scoping.md. For monorepo subprojects (where a parent already has .git/package.json), have them mkdir .one in the subproject first so the config is keyed to that dir, not the monorepo root.
Authentication
one login
one logout
one login opens the browser for OAuth authentication and automatically creates and stores an API key. If already logged in, the user can choose to log in globally or for the current directory. one logout shows current session info and confirms before clearing credentials.
Onboarding a user with no prompts: run one init --auth browser — it opens a login window (the user authenticates there), saves the key, and auto-installs this skill, all without blocking on stdin. Add -g/-p for scope (default global). For CI/CD or headless environments, use one init --auth manual --api-key sk_live_....
Core Workflow: search -> knowledge -> execute
Always follow this sequence when the user wants to do something on a connected platform:
1. List connections
one --agent connection list
Returns connected platforms with their connection keys (needed for execution), platform names in kebab-case (needed for searching), and an access field per connection telling you what you may run there.
Read access before you plan a workflow — it saves you from discovering a restriction as a 403 halfway through:
access | What it means |
|---|
{"policy": "full"} | Every action on this connection is available |
{"policy": "methods", "methods": ["GET"]} | Only actions with these HTTP methods will execute — don't propose writes |
{"policy": "actions", "actions": [...]} | Only these exact actions may run. Each has actionId, title, method — use them directly and skip actions search |
Two more fields appear only when relevant:
"knowledgeOnly": true — actions execute is disabled. Read knowledge and write integration code instead of executing.
"unresolvedActionIds": [...] — allowlisted ids that couldn't be looked up; treat them as unavailable and tell the user.
An empty actions array means the allowlist grants nothing on that connection — say so rather than searching for alternatives.
1b. Delete a connection
one --agent connection delete <connection-key>
Removes a connection. Returns {"deleted": true, "platform": "...", "key": "..."} on success. Use the connection key from one --agent connection list.
2. Search for the right action
one --agent actions search <platform> "<query>" -t execute
- Platform names are lowercase; multi-word names use dashes:
gmail, hubspot, ship-station, google-calendar
- Use
-t execute when performing actions, -t knowledge when researching or writing code
- If no results, broaden the query (e.g.,
"list" instead of "list active premium customers")
3. Get the action's knowledge (REQUIRED before executing)
one --agent actions knowledge <platform> <actionId>
This tells you exactly what parameters are required, how to structure the request, and which flags to use. Never skip this step — without it you'll guess wrong on parameters.
4. Execute
one --agent actions execute <platform> <actionId> <connectionKey> [options]
Options:
-d, --data <json> — Request body (POST, PUT, PATCH)
--path-vars <json> — Path variables for URLs with {id} placeholders
--query-params <json> — Query parameters
--headers <json> — Additional headers
--form-data — Send as multipart/form-data
--form-url-encoded — Send as application/x-www-form-urlencoded
--dry-run — Preview the request without executing
--mock — Return example response without making an API call (useful for building UI)
--skip-validation — Skip input validation against the action schema
--output <path> — Save response to a file (for binary downloads like PDFs, images, documents). Text responses (text/plain, HTML, CSV, XML) render inline automatically; --output is only needed for genuinely binary payloads.
--no-cache — Bypass the cached action details and re-fetch them; the fresh details still refresh the cache (execution itself is never cached)
The CLI validates required parameters before executing. Missing params return a structured error with the flag name, parameter name, and description. Pass --skip-validation to bypass.
Examples:
one --agent actions execute shopify <actionId> <connectionKey>
one --agent actions execute hubspot <actionId> <connectionKey> \
-d '{"properties": {"email": "jane@example.com", "firstname": "Jane"}}'
one --agent actions execute shopify <actionId> <connectionKey> \
--path-vars '{"order_id": "12345"}' \
--query-params '{"limit": "10"}'
one --agent actions execute gmail <actionId> <connectionKey> \
--path-vars '{"userId": "me", "id": "msg123"}' \
--query-params '{"format": "metadata", "metadataHeaders": ["From", "Subject", "Date"]}'
Parallel execution
Execute multiple actions concurrently with --parallel, separating each action with --:
one --agent actions execute --parallel \
gmail send-email conn123 -d '{"to":"a@b.com"}' \
-- slack post-message conn456 -d '{"text":"done"}'
All segments are validated before any execution. Failed actions don't block others. Use --max-concurrency <n> (default 5) to control batching. Agent-mode output: {"parallel":true,"results":[...],"succeeded":N,"failed":N,"totalDurationMs":N}. Each result carries "_preflight":{"cache":"hit"|"miss"} showing whether that action's details were served from cache.
Error Handling
All errors return JSON: {"error": "message"}. Parse output as JSON and check for the error key.
Important Rules
- Always use
--agent flag for structured JSON output
- Platform names are lowercase; multi-word names use dashes (
hubspot not HubSpot, google-calendar not googleCalendar)
- Always use the exact action ID from search results — never guess or construct them
- Always read knowledge before executing — it has required params, validation rules, and caveats
- JSON values passed to
-d, --path-vars, --query-params must be valid JSON (use single quotes around JSON to avoid shell escaping)
- Do NOT pass path or query parameters inside the
-d body flag
Caching
Knowledge and search responses are cached locally (~/.one/cache/). Subsequent calls for the same action serve instantly from disk. actions execute reuses the cached action details for its preflight lookup, so after a knowledge call (or a prior execute of the same action) it makes a single API call — the action itself.
- Cache is automatic — no setup required
- Default TTL: 1 hour (configurable via
ONE_CACHE_TTL env var)
- In
--agent mode, responses include a _cache field: {"hit": true, "age": 1423, "fresh": true}; execute responses include "_preflight": {"cache": "hit"|"miss"}
- Use
--no-cache to force a fresh fetch: works on knowledge, search, and execute (refreshes execute's action-details lookup)
- Use
--cache-status to check cache state without fetching
- Manage cache:
one cache list, one cache clear, one cache update-all
- Execution responses are NEVER cached — the action always runs live; only action metadata (docs, method, path, schema) is cached
Unified Memory
One ships a local memory store (a real Postgres process bootstrapped on demand via the bundled embedded-postgres plugin, with a postgres plugin available for remote/self-hosted Postgres) that backs both user-authored notes and synced platform data. one mem <cmd> is the primary surface; one sync is a namespaced alias (one mem sync ...) that writes synced rows into the same store.
Zero-config. The first one mem call on a new machine auto-initializes — no separate mem init step required. The embedded-postgres plugin downloads its Postgres binaries on first run (~52MB) and writes a daemon PID/port file at ~/.one/pg/.pgserve.json so subsequent CLI invocations reuse the running cluster. If an OpenAI key is already resolvable (env, .onerc, or config.openaiApiKey), embeddings enable automatically and search becomes hybrid FTS + semantic. Otherwise you get FTS-only with a structured _upgrade hint on every response telling the user how to upgrade.
Listing synced rows. mem list <type> takes a positional namespaced type — there is no --platform flag. Synced rows live under <platform>/<model> types:
one --agent mem list "gmail/threads"
one --agent mem list "attio/attioPeople" --limit 5
one --agent mem list "google-calendar/events"
Underneath, the store has no platform column — type is the only platform-scoping mechanism. If you need raw SQL via mem sql, filter with WHERE type LIKE 'platform/%' (not WHERE platform = ...).
one --agent mem add note '{"content":"..."}' --tags work --weight 7
one --agent mem update <id> '{"status":"done"}'
one --agent mem search "deadline"
one --agent mem list note --limit 20
one --agent mem link <from-id> <to-id> relates_to --bi
one --agent mem key <id> --add email:x@y.com
one --agent mem find-by-source attio/attioPeople:abc-1
one --agent mem find-by-key email:jane@acme.com
one --agent mem find-by-key email:jane@acme.com --type gmail/gmailThreads
one --agent mem find-by-key email:a@x.com email:b@y.com
one --agent mem reindex --searchable --type attio/attioPeople
one --agent mem status
one --agent mem doctor
Don't confuse mem key with mem find-by-key. mem key WRITES the merge column (keys[]) on one record — adding a key another active record already owns is an error, and --set replaces the whole array. mem find-by-key only READS, across both key columns. If you want "show me everything about this person", you always want find-by-key.
find-by-key agent output is grouped by record type:
{
"keys": ["email:jane@acme.com"],
"total": 13,
"truncated": false,
"fetchCap": 2000,
"perTypeLimit": 10,
"byType": {
"attio/attioPeople": { "count": 1, "items": [ {"id": "...", "type": "...", "data": {}, "keys": ["attio/attioPeople:J1", "email:jane@acme.com"], "updated_at"
items are whole mem records. keys and identity_keys are OMITTED, not [], when the record has none — the contact above matched on keys[] and so carries no identity_keys field at all. Always read them as (item.identity_keys ?? []).
Read it in this order:
truncated — if true, more than fetchCap (2000) records matched. total and every count are then floors, and because rows come back ordered by type, whole types sorting after the cut are MISSING from byType entirely. Re-run with --type <type> to get an accurate answer; do not report the counts as-is.
total / count — ungrouped and per-type match counts (accurate when truncated is false).
items — whole mem records, same fields as mem get, capped at perTypeLimit (--limit, default 10). count > items.length just means display truncation — raise --limit.
keys — the key form that actually matched. Lookups are lowercased/trimmed first (matching how sync writes them), with a one-shot verbatim retry for hand-written mixed-case keys, so email:Jane@Acme.com finds email:jane@acme.com.
Adding OpenAI for semantic search
Stored at the top level of ~/.one/config.json as openaiApiKey, same precedence as ONE_SECRET (env > .onerc OPENAI_API_KEY=... > project > global). Three equivalent ways to set:
one init
one --agent mem config set embedding.apiKey sk-...
export OPENAI_API_KEY=sk-...
Syncing platforms into memory
one --agent sync profiles
one --agent sync init stripe balanceTransactions
one --agent sync init attio attioPeople --config '{
"memory": {
"embed": true,
"searchable": [
"values.name[0].full_name",
"values.job_title[0].value",
"values.description[0].value",
"values.email_addresses[0].email_address"
]
}
}'
one --agent sync suggest-searchable attio/attioPeople
one --agent sync test attio/attioPeople --show-searchable
one --agent sync run stripe
one --agent sync schema stripe/customers
one --agent sync query stripe/balanceTransactions --where "status=available" --limit 20
one --agent sync search "refund"
one --agent sync list stripe
one schedule add stripe --every 1h
memory.searchable paths
Declared on the profile, drives what gets embedded + FTS-indexed. Supports numeric indexes AND [] wildcards for array fan-out:
values.name[0].full_name # numeric index (first element)
messages[].snippet # wildcard — every element's .snippet
messages[].payload.parts[].body.data # nested wildcards
Without declared paths, the default walker concatenates every string in the record — correct but often noisy for hierarchical APIs (Attio, HubSpot). Always declare paths for any profile with embed: true.
Sync rejects custom actions — profiles must use passthrough. sync init only surfaces passthrough models; sync run aborts if the list or enrich action is tagged custom. If no passthrough exists, compose a flow instead.
Connections are late-bound — profiles use "connection": { "platform": "<name>" }, not literal connectionKey strings. The key is resolved at sync time, so one add <platform> (re-auth) doesn't break the profile. For multi-account platforms, add "tag": "<connection-tag>" to disambiguate, and create the tagged connection with one add <platform> --tag <name>. Don't hardcode connection keys in profiles.
Extracting a flat field? Use derive, not transform. derive computes top-level fields from paths already in the record ("derive": { "from_email": { "path": "messages[0].payload.headers[name=From].value", "extract": "email" } }), using the same path syntax as identityKeys. transform spawns sh -c, so it needs jq on PATH and silently does nothing on Windows — never put one in a profile you intend to share. A path that resolves to nothing omits the field rather than writing null.
Installed profiles do not auto-update. sync run reads only .one/sync/profiles/<platform>_<model>.json and never merges the shipped built-in, so a profile created before a capability shipped silently lacks it — a pre-#167 gmail profile writes zero identity keys, forever, with no change in record counts. sync run warns when the built-in declares identityKeys / identityKey / enrich / dateFilter / memory that your copy lacks (agent mode: a profileDrift array). Fix with one sync init <platform> <model>, which patches rather than overwrites.
Cross-platform identity on a profile. Two separate fields, and picking the wrong one silently mangles data:
"identityKey": "properties.email" — singular. "This record IS this entity." One dot-path; the value lands in keys[] and MERGES records for the same entity across platforms (HubSpot + Attio for one person collapse into a single record).
"identityKeys": [{"prefix": "email", "path": "attendees[].email"}] — plural. "This record INVOLVES these people." Paths support [] wildcards and a [name=From] equality filter (Gmail headers). Values land in the separate identity_keys[] column, which does NOT merge — a 20-attendee event stays one event, not 20 contacts. Use this for anything with N participants.
Both are queryable with one --agent mem find-by-key <prefix>:<value>.
Enriching profiles (gmail/gmailThreads, fathom/meetings) sync in two phases: a list pass, then a detail pass that fetches full bodies/transcripts. Two things follow. Enrichment happens once per record by default — phase 2 only visits rows it has never enriched, and --full-refresh does not reset that (it reconciles deletions, it is not a detail refresh). To refresh detail content, either set enrich.invalidateOn in the profile to a list field that moves when the detail changes (historyId, updated_at) so only genuinely-changed records re-enrich automatically, or run one sync run <platform> --re-enrich to re-fetch every detail endpoint. And the list pass never overwrites an enriched record: data merges rather than replaces, and searchable_text / identity_keys[] are left alone. sync run reports these as memPreserved. So on an enriching profile without invalidateOn, a record whose upstream detail changed will look stale until you re-enrich — that is expected, not a sync failure.
Advanced features (enrich, transform, exclude, hooks, --full-refresh, alternative backends, embedding tuning): run one guide memory or one guide sync for the full reference.
Beyond Single Actions
One also supports more advanced patterns. Read the relevant reference file before using these:
- Webhook Relay — Receive webhooks from a platform and forward to another (e.g., Stripe event -> Slack message). Read
references/relay.md in this skill's directory for the full workflow.
- Multi-step Workflows — Chain actions across platforms as JSON workflow files (like n8n/Zapier but file-based). Read
references/flows.md in this skill's directory for the schema and examples. To debug: flow execute <key> --dry-run (resolve interpolations without running), --stop-after <stepId> (run up to a step then stop), and flow inspect <runId> (a past run's per-step outputs).
Adding New Connections
If the user needs a platform that isn't connected yet, tell them to run:
one add <platform>
one add <platform> --tag <name>
This is interactive and opens the browser for OAuth. After connecting, the platform will appear in one --agent connection list. Use --tag when the user has (or will have) more than one connection for the same platform so sync/flow profiles can target a specific one via "connection": { "platform": "<name>", "tag": "<name>" }.
Removing Connections
To delete a connection that is no longer needed:
one --agent connection delete <connection-key>
The connection key comes from one --agent connection list. Returns {"deleted": true, "platform": "...", "key": "..."} on success.
