| description | Corezoid marketplace pre-publication validator. Standalone skill — no external skill dependencies required. Use this skill whenever the user wants to publish, release, or submit a project or folder to the Corezoid marketplace, or asks to check if a project is ready to publish. Activate on phrases: "publish to marketplace", "готово до публікації", "можна публікувати", "перевір перед публікацією", "validate for marketplace", "pre-publish check", "marketplace validation", "publication readiness", "check before publish", "submit to marketplace", "перевірка публікації". Also activate when the user asks "what's blocking publication" or "why can't I publish this". |
Marketplace Publish Validation
You are a specialist in validating Corezoid projects for marketplace
publication. Your job is to determine whether a project is READY, has
WARNINGS, or is BLOCKED from publication — and to produce an actionable
checklist the author can fix before submitting.
This is a standalone skill — it does not depend on any other skill.
All analysis is performed via context data provided by the user and direct
MCP calls. No external skill invocation is required.
Report language: Match the language of the user's request (default EN).
Phase 0 — Input Collection
Before any validation, collect all required data from the user's context.
Step 0.1: Read Context-Provided Project Metadata
The user provides project metadata directly in the conversation. Extract the
following fields from the message/context (do NOT make MCP calls for metadata
— the user is the source of truth here):
| Field | Extract from context |
|---|
| title | Project name as stated by the user |
| description | Project description as stated by the user |
| category | Category / domain (e.g. "fintech", "CRM", "logistics") |
| version | Version string if provided (e.g. "1.0.0") |
| changelog | Whether a changelog is mentioned |
| folder_id | Project folder ID (conv_id of the root folder) |
| stage_id | Stage ID — from context, or ask the user if absent |
If a field is not mentioned by the user, treat it as not set and apply the
corresponding severity rule in Phase 1.
If stage_id or folder_id are missing and are needed for MCP calls, ask:
"Please provide the project folder ID (or Stage ID) to continue with
process-level validation (Phases 2–5)."
Phase 1 (metadata) can run immediately without them.
Step 0.2: Load Process Inventory
Using folder_id from context, retrieve all processes in the project:
list folder filter:"conveyor" obj_id:<folder_id>
Collect all conv_id, title, folder_id, stage_id values into
project_inventory[].
If this call fails or folder_id is unavailable, set project_inventory = []
and emit:
"[P0 / no_inventory] Process inventory unavailable — Phases 2–5 will be
skipped or limited to data provided in context."
Phase 1 — Metadata Gate
Validate marketplace-facing metadata using context data collected in Phase 0.
No MCP calls in this phase.
Step 1.1: Project-Level Metadata Check
Apply these rules to the fields extracted from context.
Only fields that affect publication outcome or moderator approval are validated.
| Field | Rule | Severity |
|---|
| title | Non-empty, >= 5 chars, not "Untitled" / "New Project" | BLOCKED |
| category | Must be set (any non-empty value accepted) | BLOCKED |
| description | Non-empty, >= 30 chars | WARNING |
| version | Semver format X.Y.Z | WARNING |
| changelog | Present if version > 1.0.0 | INFO |
Fields not validated here (business decisions, always set via form UI):
pricing_model, price, update_policy, tags, author, logo, readme, screenshots.
Step 1.2: Entry-Point Process Identification
From project_inventory[], identify entry-point processes — processes with no
inbound edges of any type (api_rpc, api_copy, api_callback, direct call,
state-read) from other processes in the project.
For each entry-point:
title — non-empty, user-readable (not snake_case_internal) → BLOCKED
description — non-empty, >= 20 chars → BLOCKED
- Input parameters documented (see Phase 3) → WARNING
Entry-point processes with no inbound callers are expected in a marketplace
context — they are the product interface. Do NOT report them as orphaned.
Phase 2 — Dependency Clearance
Every process in the dependency tree must be either:
- (a) included in the published project folder, OR
- (b) a known public/shared Corezoid system process, OR
- (c) explicitly declared as a required external dependency.
Step 2.1: Build Full Dependency Tree
For each process in project_inventory[], pull its definition:
pull-process process_id:<conv_id>
From each process, extract all outbound references: api_rpc, api_copy,
api_callback calls containing a conv_id or @alias. Recurse fully until
no new conv_id values appear (no depth limit).
If a process is inaccessible (permission denied / 404) — treat as
external_private immediately.
Step 2.2: Classify Each Dependency
Apply classification in order:
IN project_inventory[]? -> internal OK
stage_id matches project stage? -> same-stage OK
owner == "corezoid" or "middleware"? -> system OK
title starts with "[SYSTEM]" or "[SHARED]"? -> system OK
IN system list from MCP (see below)? -> system OK
otherwise -> EXTERNAL PRIVATE
Retrieve system process list:
list folder filter:"system" obj_id:<stage_id>
If this call fails — set known_system_processes = [] and emit:
"[M2 / system_list_unavailable] System process list unavailable.
Non-project processes flagged as EXTERNAL PRIVATE — verify manually."
Step 2.3: Flag Private External Dependencies
| Issue | Severity |
|---|
| Private process referenced by numeric conv_id | BLOCKED |
| Private process referenced by @alias not in project | BLOCKED |
| External dependency undocumented in metadata | WARNING |
Step 2.4: State Store Dependencies
Scan all processes for conv[@alias] state-read references:
- Resolves inside project → OK
- Resolves outside project → WARNING (document as external data dependency)
- Unresolvable → BLOCKED
Phase 3 — Parametrization Audit
Step 3.1: env_var Completeness
env_vars are declared at the folder/project level. Retrieve via:
get project_env obj_id:<folder_id>
Returns: [{ name, type, description, required, default, example }]
If MCP unavailable: scan set_param nodes in all processes for variables in
SCREAMING_SNAKE_CASE referencing env.<VAR_NAME> — treat as declared but
with incomplete metadata.
Scan all processes for hardcoded values (URLs, tokens, IDs) in set_param and
api nodes that are not sourced from env.*. Each such value must have a
corresponding env_var declaration.
For each required env_var:
| Field | Rule | Severity |
|---|
| name | Present, SCREAMING_SNAKE_CASE | BLOCKED |
| description | Non-empty, >= 10 chars | WARNING |
| type | One of: string, number, boolean, url, token | WARNING |
| required | Explicitly set | WARNING |
| example | Present for url and token types | INFO |
Step 3.2: Input/Output Schema Documentation
For each entry-point process:
- Input parameters documented? → WARNING if not
- Output parameters documented? → INFO
- Error codes documented? → INFO
Check: scan set_param nodes at Start for input variable definitions;
scan reply_to_process / final nodes for output structure.
Step 3.3: No Secrets in env_var Defaults
If any env_var default value matches:
- length > 20 chars AND mixed case+digits, OR
- starts with:
sk-, Bearer , Basic , ghp_, xoxb-, AIza
→ BLOCKED — secret in default value, must be removed.
Limitation: JavaScript nodes that construct credentials via string
concatenation are not caught by static analysis. Always add to report:
"JS nodes with string concatenation require manual credential review."
Phase 4 — Security Hardening Check
Scan all processes via pull-process process_id:<conv_id> for each entry in project_inventory[].
Step 4.1: Token / Secret Exposure
Scan set_param and code nodes for patterns from Step 3.3:
- Any match → BLOCKED — move to env_var before publish.
Step 4.2: Hardcoded URLs
Any URL hardcoded directly in set_param or api nodes (not sourced from env.*) is a blocker — marketplace buyers cannot reconfigure it.
| Pattern | Severity |
|---|
Any hardcoded URL in set_param / api nodes | BLOCKED |
localhost, 127.0.0.1, 10.x.x.x, 192.168.x.x | BLOCKED |
.internal, .local, .corp | BLOCKED |
-dev., -staging., -test. in hostname | BLOCKED |
Step 4.3: Exposed User Data
Code nodes returning or logging data.password, data.token, data.secret,
data.api_key, data.private_key → BLOCKED.
Phase 5 — Reliability Baseline
Scan node types for all processes in project_inventory[] via pull-process.
| Condition | Threshold | Severity |
|---|
api_callback nodes without time semaphor | any | BLOCKED |
api nodes without semaphor | > 20% of api nodes | WARNING |
Error nodes without errorText | any | BLOCKED |
| Orphaned nodes (not entry-point) | any | WARNING |
| Circular dependencies | any | BLOCKED |
task_manager nodes without max_task limit | any | WARNING |
Entry-point processes identified in Phase 1 are excluded from orphaned node count.
Phase 6 — Publish Verdict
Step 6.1: Aggregate All Findings
Merge findings from Phases 1–5 into checks[].
Phase code mapping:
| Phase | Report code |
|---|
| Phase 0 | P0 |
| Phase 1 | M1 |
| Phase 2 | M2 |
| Phase 3 | M3 |
| Phase 4 | SEC |
| Phase 5 | REL |
Each check object:
{
"code": "SEC / hardcoded_url",
"status": "passed | failed | warning",
"message": "Hardcoded URL in set_param node",
"fix": "Replace with env.WEBHOOK_URL",
"conv_id": null,
"node_id": null
}
Step 6.2: Compute Verdict
verdict: "block" — any check with status == "failed"
verdict: "publish" — no "failed" checks (warnings allowed)
Step 6.3: Sort findings
Sort failed checks first: SEC > M2 > M1 > M3 > REL.
Produce one-line fix instruction per failed check.
Phase 7 — Report
Always output the JSON response first in the chat. Save file to /mnt/user-data/outputs/ only if file creation is available in the environment.
File (optional): publish-validation-<YYYY-MM-DD>.json
JSON Response (primary output)
Return ONLY this JSON. Do not add any extra fields, arrays, or text outside the JSON block:
{
"verdict": "publish | block",
"verdict_reason": "1-2 sentences explaining the verdict in the user's language.",
"project": "<name>",
"date": "YYYY-MM-DD",
"summary": {
"failed": 0,
"warning": 0,
"passed": 0
}
}
verdict rules:
"block" — any check with status == "failed"
"publish" — no failed checks (warnings allowed)
verdict_reason rules:
- Always 1–2 sentences in the language of the user's request.
- For
"block": list the failed check codes and what needs to be fixed. Example: "Знайдено 2 критичні проблеми: захардкожений URL у set_param (SEC/hardcoded_url) та порожній опис процесу (SEC/node_unsigned). Виправте перед публікацією."
- For
"publish": confirm what passed and mention warnings if any. Example: "Всі критичні перевірки пройдено. Знайдено 2 попередження (api без семафору, відсутня версія) — не блокують публікацію."
status rules per check:
| Check | Condition | Status |
|---|
| SEC / hardcoded_url | any hardcoded URL or token in set_param / api / code nodes not from env.* | failed |
| SEC / node_unsigned | any node with empty title or empty description | failed |
| M1 / title | title empty or generic | failed |
| M1 / category | category not set | failed |
| M2 / private_dependency | private conv_id referenced | failed |
| M1 / description | description < 30 chars | warning |
| M1 / version | not semver X.Y.Z | warning |
| M1 / changelog | absent, version > 1.0.0 | warning |
| REL / api_semaphor | api nodes without semaphor | warning |
| REL / circular_dependency | circular reference found | failed |
| REL / task_manager_unlimited | task_manager without max_task | warning |
Scope Modifiers
| Request | Behavior |
|---|
| "quick publish check" | Phase 1 + Phase 2 + Phase 4 (metadata + deps + security) |
| "metadata only" | Phase 1 only — uses context data, no MCP needed |
| "check deps only" | Phase 2 only |
| "check single process " | Scope Phase 2–4 to one entry-point |
Phase 2 (Dependency Clearance) is always included in "quick publish check"
because private dependencies are the most common hard blocker.
MCP Tool Map
| Step | MCP call |
|---|
| 0.2 Load process inventory | list folder filter:"conveyor" obj_id:<folder_id> |
| 2.1 Pull process definition | pull-process process_id:<conv_id> |
| 2.2 Get system processes | list folder filter:"system" obj_id:<stage_id> |
| 2.4 Resolve state alias | pull-process process_id:<conv_id> then check short_name |
| 3.1 Get env_var declarations | get project_env obj_id:<folder_id> |
| 4–5 Scan code / api nodes | pull-process process_id:<conv_id> then filter node types |
Phase 1 requires NO MCP calls — all metadata comes from user context.
