/heal-skill — Automated Skill Maintenance

Purpose: Detect and auto-fix common skill hygiene issues across the skills/ directory.

YOU MUST EXECUTE THIS WORKFLOW. Do not just describe it.

Quick Start

/heal-skill                    # Check all skills (report only)
/heal-skill --fix              # Auto-repair all fixable issues
/heal-skill --strict           # Check all skills, exit 1 on findings (CI mode)
/heal-skill skills/council     # Check a specific skill
/heal-skill --fix skills/vibe  # Fix a specific skill

---

What It Detects

Ten checks, run in order:

Code	Issue	Auto-fixable?
MISSING_NAME	No name: field in SKILL.md frontmatter	Yes -- adds name from directory
MISSING_DESC	No description: field in SKILL.md frontmatter	Yes -- adds placeholder
NAME_MISMATCH	Frontmatter name differs from directory name	Yes -- updates to match directory
UNLINKED_REF	File in references/ not linked in SKILL.md	Yes -- converts bare backtick refs to markdown links
EMPTY_DIR	Skill directory exists but has no SKILL.md	Yes -- removes empty directory
DEAD_REF	SKILL.md references a non-existent references/ file	No -- warn only
SCRIPT_REF_MISSING	SKILL.md references a scripts/ file that does not exist	No -- warn only
INVALID_AO_CMD	SKILL.md references an ao subcommand that does not exist (only runs if ao is on PATH)	No -- warn only
DEAD_XREF	SKILL.md references a /skill-name that has no matching skill directory	No -- warn only
CATALOG_MISSING	A user-invocable skill is missing from the using-agentops catalog	No -- warn only

---

Execution Steps

Step 1: Run the heal script

# Check mode (default) -- report only, no changes
bash skills/heal-skill/scripts/heal.sh --check

# Fix mode -- auto-repair what it can
bash skills/heal-skill/scripts/heal.sh --fix

# Target a specific skill
bash skills/heal-skill/scripts/heal.sh --check skills/council
bash skills/heal-skill/scripts/heal.sh --fix skills/council

Step 1A: Audit Codex Parity Drift When The Codex Bundle Looks Wrong

When the problem is not source-skill hygiene but skills-codex/ drift, run the Codex parity audit first:

bash scripts/audit-codex-parity.sh
bash scripts/audit-codex-parity.sh --skill swarm

Use this when a checked-in Codex skill still contains Claude-era primitives (TaskCreate, TaskList, Tool: Task), Claude backend references, or obviously broken runtime rewrites.

Repair rule: keep canonical shared behavior in skills/<name>/SKILL.md. Update skills-codex/<name>/SKILL.md when the shipped Codex artifact is wrong, and keep durable Codex-only tailoring in skills-codex-overrides/<name>/SKILL.md.

After repair:

bash scripts/audit-codex-parity.sh
bash scripts/validate-codex-override-coverage.sh
bash scripts/validate-codex-generated-artifacts.sh --scope worktree

Step 2: Interpret results

• Exit 0: All clean, no findings. Also exit 0 for --check mode with findings (report-only).
• Exit 1: Findings reported with --strict or --fix flag. In --fix mode, fixable issues were repaired; re-run --check to confirm.

Step 3: Report to user

Show the output. If --fix was used, summarize what changed. If DEAD_REF findings remain, advise the user to remove or update the broken references manually.

Output Format

One line per finding:

[MISSING_NAME] skills/foo: No name field in frontmatter
[MISSING_DESC] skills/foo: No description field in frontmatter
[NAME_MISMATCH] skills/foo: Frontmatter name 'bar' != directory 'foo'
[UNLINKED_REF] skills/foo: refs/bar.md not linked in SKILL.md
[EMPTY_DIR] skills/foo: Directory exists but no SKILL.md
[DEAD_REF] skills/foo: SKILL.md links to non-existent refs/bar.md
[SCRIPT_REF_MISSING] skills/foo: references scripts/bar.sh but file not found
[INVALID_AO_CMD] skills/foo: references 'ao badcmd' which is not a valid subcommand
[DEAD_XREF] skills/foo: references /nonexistent but skill directory not found
[CATALOG_MISSING] using-agentops: bar is user-invocable but missing from catalog

---

Notes

• The script is idempotent -- running --fix twice produces the same result.
• DEAD_REF, SCRIPT_REF_MISSING, INVALID_AO_CMD, DEAD_XREF, and CATALOG_MISSING are warn-only because the correct resolution requires human judgment.
• INVALID_AO_CMD only runs if the ao CLI is available on PATH. Skipped silently otherwise.
• CATALOG_MISSING is a global check (not per-skill) and only runs when using-agentops/SKILL.md exists.
• When run without a path argument, scans all directories under skills/.
• Use --strict for CI gates: exits 1 on any finding. Without --strict, check mode exits 0 even with findings.
• For Codex parity drift, use the audit script plus override-layer repair workflow in references/codex-parity.md. The shell fixer is intentionally not allowed to rewrite generated Codex bodies directly.

Examples

Running a health check across all skills

User says: /heal-skill

What happens:

1. The heal script scans every directory under skills/, checking each for the ten issue types (missing name, missing description, name mismatch, unlinked references, empty directories, dead references, script reference integrity, CLI command validation, cross-reference validation, catalog completeness).
2. Findings are printed one per line with issue codes (e.g., [NAME_MISMATCH] skills/foo: Frontmatter name 'bar' != directory 'foo').
3. The script exits with code 0 in check mode (even with findings), or code 1 with --strict or --fix flags.

Result: A diagnostic report showing all skill hygiene issues across the repository, with no files modified.

Auto-fixing a specific skill

User says: /heal-skill --fix skills/vibe

What happens:

1. The heal script inspects only skills/vibe/, running all per-skill checks against that skill.
2. For each fixable issue found (e.g., MISSING_NAME, UNLINKED_REF), the script applies the repair automatically -- adding the name from the directory, converting bare backtick references to markdown links, etc.
3. Any DEAD_REF findings are reported as warnings since they require human judgment to resolve.

Result: The skills/vibe/SKILL.md is repaired in place, with a summary of changes applied and any remaining warnings.

Troubleshooting

Problem	Cause	Solution
DEAD_REF findings persist after --fix	Dead references are warn-only because the correct fix (delete, create, or update) requires human judgment	Manually inspect each dead reference and either create the missing file, remove the link from SKILL.md, or update the path
Script reports EMPTY_DIR for a skill in progress	The skill directory was created but SKILL.md has not been written yet	Either add a SKILL.md to the directory or remove the empty directory. Running --fix will remove it automatically
NAME_MISMATCH fix changed the wrong name	The script always updates the frontmatter name to match the directory name, not the other way around	If the directory name is wrong, rename the directory first, then re-run --fix
Script exits 0 but a skill still has issues	The issue type is not one of the ten checks the heal script detects	The heal script covers structural hygiene only. Content quality issues require manual review or /council validation
Running --fix twice produces different output	This should not happen -- the script is idempotent	File a bug. Check if another process modified the skill files between runs
skills-codex/ keeps regressing after sync	Mechanical conversion is preserving the wrong semantics	Run bash scripts/audit-codex-parity.sh, then move the durable Codex body rewrite into skills-codex-overrides/<name>/SKILL.md instead of patching generated output
