Validate and Fix

Restore a clean repository by identifying root causes, applying deterministic repairs, and re-running the full check suite. Validation passing is necessary but not sufficient: supporting scripts and templates must still implement the skill's stated behavior.

Operating Rules

• Inspect the working tree and current branch before changing files. Preserve unrelated user edits.
• Run diagnostics before formatting or auto-fixing so the original failures are visible.
• Apply mechanical fixes automatically only when intent is unambiguous.
• Never delete an orphan file, rename a skill, replace a symlink, or weaken a validator merely to make CI green without determining the intended behavior.
• Treat parser, network, timeout, and missing-data paths as first-class test cases; errors must not become favorable conclusions.
• When a validator conflicts with valid formatted Markdown or repository policy, fix the validator and add a regression case rather than distorting every skill.
• Do not commit, push, merge, or discard changes unless requested.

Workflow

1. Capture Repository State

git status --short
git diff --stat
git diff

Identify user-owned changes, generated files, symlinks, and the last known good check. Do not reset the tree.

2. Run Focused Diagnostics

just validate-verbose
just readme-table --check
just typecheck
just lint
just fmt-check

Run just check after individual failures have been understood. Record each failure by file, rule, and likely root cause rather than fixing messages one by one without a model.

3. Classify the Failure

Frontmatter or Name

• name must be lowercase kebab-case and match the parent directory.
• description must be one physical YAML line, nonempty, within the schema limit, and explain both capability and trigger conditions.
• Remove unsupported keys only after checking the current schema and whether the validator itself is stale.

Broken Links or File References

Resolve relative to the document containing the link. Preserve anchors and code-formatted link labels. Confirm the target exists on the current branch and is not a broken symlink.

Orphan Resources

Determine whether the file is:

1. necessary and should be linked;
2. duplicated and should be consolidated into a canonical implementation;
3. obsolete and safe to remove;
4. generated or package metadata that should be explicitly exempt.

Do not add meaningless references solely to silence the check.

Sources

A ## Sources item must be a logical Markdown list item containing [Title](https://...). Formatters may wrap long links across physical lines; the validator should parse the logical item. Verify time-sensitive claims against current authoritative sources.

Word or Size Limit

Remove repetition and move optional depth into a linked reference. Do not move critical operating rules, safety boundaries, failure states, or the output contract out of the main skill merely to satisfy a count.

Formatting

Use repository formatters:

just fmt

Confirm idempotence by running just fmt-check afterward. If a construct toggles on repeated formatting, simplify the Markdown syntax or pin/fix the formatter configuration; do not add a CI job that silently commits forever.

TypeScript, Scripts, or Templates

Bring every bundled TypeScript helper under the root typecheck. Exercise safe valid, invalid, empty, and failure-path inputs. Check that:

• input validation is explicit;
• timestamps and evidence sources are retained;
• network and parse failures remain unknown/error;
• destructive or external actions require authorization;
• templates preserve unresolved facts;
• package dependencies and lockfiles match imports;
• scripts, templates, examples, and the main skill agree.

README Freshness

Regenerate only through the canonical command:

just readme-table --write

Inspect that only the marker-delimited generated region changed.

Plugin Exposure

For marketplace skills, verify the expected relative symlink, target, and SKILL.md. Do not replace a conflicting path automatically.

4. Apply the Smallest Coherent Repair

Fix the root cause and all directly inconsistent artifacts in one pass. Add or adjust regression coverage when a validator or helper bug allowed the failure. Keep a short decision log for non-obvious changes.

5. Re-run the Complete Suite

just fmt
just check

Run the same checks in CI when available. A final pass must include marketplace and internal skills, TypeScript helpers, formatting, README freshness, and resource validation.

6. Review the Diff

git status --short
git diff --check
git diff --stat
git diff

Look specifically for accidental content loss, changed legal/security claims, stale generated files, secrets, absolute local paths, broken symlinks, and broad formatter churn.

Output Contract

Report:

1. original failures and root causes;
2. files changed and rationale;
3. automatic fixes versus judgment calls;
4. regression protection added;
5. final local/CI check results;
6. remaining warnings or untested external behavior;
7. any change deliberately left for human review.
