PM Skill Validate

This skill audits an existing pm-skills skill against the repo's structural conventions and quality criteria. It produces a validation report that a human can scan and that

/pm-skill-iterate

can consume as input.

The validator checks two tiers:

Tier 1 (Structural) . deterministic checks that mirror CI: frontmatter, naming, file presence, description word count.
Tier 2 (Quality) . LLM-assessed coherence checks: does the output contract reference the template? Is the example complete? Are checklist items testable?

When to Use

After creating a skill with
```
/pm-skill-builder
```
, before shipping
After manually editing a skill, to confirm it still passes conventions
Before running
```
/pm-skill-iterate
```
, to identify what needs improvement
When a convention changes, to audit which skills need updating (batch mode)
When reviewing a contributed skill for quality and completeness

When NOT to Use

To create a new skill from scratch -> use
```
/pm-skill-builder
```
To fix or improve a skill -> use
```
/pm-skill-iterate
```
(feed it this report)
To run CI checks in a pipeline -> use
```
scripts/lint-skills-frontmatter.sh
```
(this skill is for interactive, deeper-than-CI validation)

Instructions

When asked to validate a skill, follow these steps:

Step 1: Identify the Target

Accept the skill name in any form:

Directory name:
```
deliver-prd
```
Full path:
```
skills/deliver-prd/SKILL.md
```
Slash command:
```
/prd
```

Resolve to the canonical directory path:

skills/{name}/

If the skill directory does not exist, report immediately:

# Validation Report: {input}
Result: FAIL
Skill directory `skills/{input}/` does not exist.

Batch mode: If the input is

--all

, run Tier 1 structural checks across all skills and produce a summary table (see Step 5). Do not run Tier 2 in batch mode.

Step 2: Read Skill Files

Read all files in the skill directory:

File	Required	Purpose
`SKILL.md`	yes	Frontmatter + instructions
`references/TEMPLATE.md`	yes	Output template
`references/EXAMPLE.md`	yes	Worked example
`HISTORY.md`	no	Version history (if present)

Step 3: Run Tier 1 . Structural Checks

Run these deterministic checks. Each produces a

PASS

FAIL

line.

Check ID	What to check	Pass condition
`name-match`	Frontmatter `name` matches directory name	Exact string match
`description-present`	Frontmatter `description` exists	Non-empty value
`description-length`	Description word count	20-100 words
`version-present`	Frontmatter `version` exists	Non-empty, valid SemVer
`updated-present`	Frontmatter `updated` exists	Non-empty, ISO date
`license-present`	Frontmatter `license` exists	Non-empty value
`phase-classification`	Phase/classification consistency	Domain has `phase:` , foundation/utility has `classification:` , not both
`template-exists`	`references/TEMPLATE.md` exists	File present
`template-sections`	TEMPLATE.md has sufficient structure	≥3 `##` level-2 headers
`example-exists`	`references/EXAMPLE.md` exists	File present
`command-exists`	Command file exists in `commands/`	File present and references correct skill path
`agents-entry`	AGENTS.md has an entry for this skill	Entry exists with matching `Path:`

Step 4: Run Tier 2 . Quality Checks

Run these LLM-assessed checks. Each produces a

PASS

WARN

, or

INFO

line. Tier 2 findings are capped at

WARN

unless objectively grounded (placeholder leakage is the exception . it can

FAIL

Check ID	What to assess	How to assess	Max severity
`output-contract-coverage`	SKILL.md references the template	Check for explicit reference to `references/TEMPLATE.md` or "use the template" in an Output section. Accept either pattern as valid. WARN only if template is not referenced at all.	WARN
`checklist-verifiability`	Quality checklist items are testable	Read each checklist item. Flag items that are vague ("is good quality") vs. specific ("metrics are measurable"). WARN if ≥2 items are vague.	WARN
`example-completeness`	EXAMPLE.md fills all template sections	Compare `##` headers in TEMPLATE.md against `##` headers in EXAMPLE.md. WARN if EXAMPLE.md is missing sections that appear in the template. Also check for unresolved placeholders. Line count is informational only . report it but do not gate on it.	WARN
`template-example-alignment`	EXAMPLE.md follows TEMPLATE.md structure	Compare section header ordering. WARN if EXAMPLE.md has sections in a different order or uses different header names than TEMPLATE.md.	WARN
`description-actionability`	Description tells when to use the skill	Check for a trigger phrase like "Use when..." or "Use for..." in the frontmatter description. WARN if the description only says what the skill does without indicating when to use it.	WARN
`instruction-clarity`	Instructions are numbered and imperative	Check for `### Step` headings or a numbered list pattern in the Instructions section. WARN if instructions are prose paragraphs without clear step structure.	WARN
`placeholder-leakage`	No leftover scaffolding in any shipped file	Scan SKILL.md, TEMPLATE.md, and EXAMPLE.md for: `[Placeholder]` or `[Feature Name]` patterns, `<!-- ... -->` HTML comments (except the license header), template guidance blockquotes that should have been removed, and authoring notes like "TODO" or "FIXME". FAIL if any are found . this is objectively grounded.	FAIL
`when-not-to-use`	"When NOT to Use" section present in SKILL.md	Check for a section with "When NOT to Use" or similar heading. INFO only . this is present in 1/27 shipped skills and is not yet a convention.	INFO

Quality standard framing: These checks validate against current library conventions . what the shipped library actually does today. Findings graded WARN or INFO represent the v2.8 quality standard that newer skills (built with

/pm-skill-builder

) meet. Older skills may legitimately receive these findings until iterated through the lifecycle.

Step 5: Produce the Validation Report

Assemble the report using this exact structure. F-11 (

/pm-skill-iterate

) parses this report by section headings and pipe-delimited fields.

# Validation Report: {skill-name}
Date: {YYYY-MM-DD}
Skill version: {version from frontmatter}
Validator version: 1.0.0
Report schema: v1
Result: {PASS | WARN | FAIL}

## Summary
{1-2 sentence overall assessment.}
Errors: {n} | Warnings: {n} | Info: {n}

> Tier 2 findings are heuristic quality assessments and may require human review.

## Structural Checks
- {STATUS} | structural | {check-id} | {message}
- {STATUS} | structural | {check-id} | {message}
...

## Quality Checks
- {STATUS} | quality | {check-id} | {message}
- {STATUS} | quality | {check-id} | {message}
...

## Recommendations
1. {STATUS} | {check-id} | Target: {file-path}
   Action: {what to do}
2. {STATUS} | {check-id} | Target: {file-path}
   Action: {what to do}
...

Report rules:

Result = worst severity found: any FAIL →
```
FAIL
```
, else any WARN →
```
WARN
```
, else
```
PASS
```
.
Structural Checks: one line per Tier 1 check. STATUS is
```
PASS
```
or
```
FAIL
```
.
Quality Checks: one line per Tier 2 check. STATUS is
```
PASS
```
,
```
WARN
```
, or
```
INFO
```
.
Recommendations: only include checks that did NOT pass. Each recommendation includes the check ID, the target file path, and a specific action.
If all checks pass, the Recommendations section should say: "No issues found."
Omit passing checks from Recommendations . only list findings that need action.

Batch mode output (when input is

--all

Run Tier 1 structural checks only across all skills. Produce a summary table:

# Batch Validation Summary
Date: {YYYY-MM-DD}
Validator version: 1.0.0
Report schema: v1
Skills checked: {n}

| Skill | Result | Errors | Warnings |
|-------|--------|--------|----------|
| deliver-prd | PASS | 0 | 0 |
| define-hypothesis | WARN | 0 | 1 |
| foundation-persona | FAIL | 1 | 0 |
...

Skills passing: {n}/{total}
Run `/pm-skill-validate {skill}` for a detailed report.

Degraded Mode

If you cannot read skill files directly (e.g., running via MCP or in an embedded environment without file system access):

Ask the user to provide the content of each required file:

```
skills/{name}/SKILL.md
```
```
skills/{name}/references/TEMPLATE.md
```
```
skills/{name}/references/EXAMPLE.md
```

Run all checks against the provided content.
Note in the report: "Validated from user-provided content (file system not available)."
Batch mode is not available in degraded mode . single skill only.

Output Contract

The validator MUST produce a validation report following the format in Step 5.

The report:

Uses the exact section headings:

## Summary

## Structural Checks

## Quality Checks

## Recommendations

Uses pipe-delimited check lines:
```
STATUS | TIER | CHECK-ID | message
```
Uses pipe-delimited recommendations:
```
STATUS | CHECK-ID | Target: path
```
followed by
```
Action: description
```
on the next line
Includes
```
Report schema: v1
```
in the header for F-11 compatibility
Includes the Tier 2 caveat line in the Summary section

Quality Checklist

Before delivering the report, verify:

All Tier 1 structural checks were run (not skipped)
All Tier 2 quality checks were run (not skipped) . single skill mode only
Report follows the exact section and line format from Step 5
Every non-passing check appears in Recommendations with a target file path
Result field reflects the worst severity found
Tier 2 findings are capped at WARN (except placeholder-leakage which can FAIL)
No Tier 2 check was marked FAIL unless objectively grounded
