Doctor

A user-runnable self-check for the marketplace install: four fixed, read-only diagnostic checks, each reporting PASS / WARN / FAIL / SKIP with the evidence it actually observed and a one-line fix when it fails — so a broken or half-wired install reports itself instead of failing silently (per .lsa/pitches/onboarding-diagnostics.md). Free-form cited Q&A ("what is X?", "how do I Y?") is out of scope; the doctor never answers open questions — it only runs the checks below.

Goal

Produce a four-row diagnostic table — required plugins, CLAUDE.md fragment, version consistency, gate scripts — where every verdict is backed by evidence actually observed (never a bare "OK"), and every non-PASS row carries a one-line fix.

Input

• No required arguments. An optional user symptom ("skills don't trigger", "lint is red") is echoed above the report — the four checks themselves are fixed and always all run.
• The current project's files (read-only), and — when readable — Claude Code's plugin state under ~/.claude/plugins/ (installed_plugins.json, the marketplaces/NVZver/ clone).

Steps

1. Detect the environment. Read .claude-plugin/marketplace.json at the project root. If it exists with "name": "NVZver", the doctor is running inside the marketplace source repo; otherwise inside a consumer project. This picks the version source-of-truth in Step 4 and run-vs-SKIP in Step 5. Observable result: the environment named (marketplace-source / consumer) with the evidence quoted (the "name" line, or "no .claude-plugin/marketplace.json").

2. Check 1 — required plugins installed (core + lsa). Installation is only heuristically observable from inside a project, so gather evidence in order: (a) the session's own context — do core:* and lsa:* skills appear in the available-skills list? (b) ~/.claude/plugins/installed_plugins.json — do the keys core@NVZver and lsa@NVZver exist? Both plugins evidenced → PASS. Either missing from every readable source → FAIL for the missing one (fix: /plugin install <name>@NVZver, then /reload-plugins). No evidence source readable in this environment → WARN "not determinable", naming what was looked for. Never infer "installed" from the plugin source directories being present in the repo — source on disk is not an install. Observable result: the verdict plus the exact evidence found (skill names seen, or the JSON keys), or the not-determinable reason.

3. Check 2 — core/CLAUDE.md fragment present in the project CLAUDE.md. Grep the project's CLAUDE.md for the four always-on rule anchors the fragment declares (core/CLAUDE.md): ground-rules, core/output, flow-selector, reuse-first. All four found → PASS. Some found → WARN — partial merge (users adapt the fragment; report per-anchor, name each missing one). None found, or no CLAUDE.md at all → FAIL (fix: merge core/CLAUDE.md into the project CLAUDE.md, per core/README.md § "Merge the CLAUDE.md fragment"). Observable result: a per-anchor found/missing list, each hit cited as CLAUDE.md:<line>.

4. Check 3 — installed plugin versions vs source manifests. For each NVZver plugin evidenced installed in Step 2, read the installed version (the version field in installed_plugins.json, or the versioned cache path) and compare it to the source manifest <plugin>/.claude-plugin/plugin.json — the repo's own manifest when inside the marketplace source repo, else the synced clone under ~/.claude/plugins/marketplaces/NVZver/. All equal → PASS. Any mismatch → WARN, listing each <plugin>: installed X ≠ source Y (fix: update the NVZver marketplace and the stale plugins via /plugin, then /reload-plugins). Neither installed state nor a source manifest readable → WARN "not determinable". Observable result: per-plugin installed → source version pairs.

5. Check 4 — gate scripts pass. Inside the marketplace source repo only: run bash scripts/lint.sh, bash scripts/check-links.sh, bash scripts/check-citations.sh, bash scripts/check-version-changelog.sh. All exit 0 → PASS. Any nonzero → FAIL, quoting the script's own failing line as the fix pointer. In a consumer project → SKIP ("gate scripts are repo-internal to the marketplace source repo — nothing to run here"). Observable result: the four script exit codes, or the SKIP reason.

6. Render the report. One table, one row per check: # | Check | Verdict | Evidence | Fix — Verdict ∈ PASS / WARN / FAIL / SKIP; Evidence is what was observed (a quoted key, a file:line, an exit code); Fix is one line (— on PASS/SKIP). Close with a one-line overall verdict — PASS (all rows PASS), PASS WITH WARNINGS (any WARN or SKIP, no FAIL), FAIL (any FAIL) — labels per core/knowledge/output-vocabulary.md. Observable result: the environment line + table + overall verdict delivered as the turn-final message.

Output

The environment line, a four-row per-check table (# | Check | Verdict | Evidence | Fix), and a one-line overall verdict (PASS / PASS WITH WARNINGS / FAIL). Human-readable, delivered turn-final; every Evidence cell holds something the reader can re-check (a file:line, a JSON key, an exit code) — never a bare assertion.

Constraints

• Read-only. Never create, edit, or delete any user file; never install, update, or remove a plugin; never fetch the network. The doctor reports and instructs — the human fixes (the Step 5 scripts are the repo's own detect-and-report-only checks; auto-repair is a pitch no-go).
• No new shipped executable. Every check runs through the agent's existing tools (Read / Grep / read-only Bash) and the repo's already-existing scripts/*.sh; this skill ships no script or hook of its own — the trust boundary stays pure Markdown.
• Honest verdicts only. A check whose evidence is not observable in the current environment reports WARN or SKIP with the reason — never a guessed PASS, never a fabricated FAIL. Per ground-rules Rule 7 Done is a gate-proven, cited predicate.
• Fixed procedure, not Q&A. The doctor runs exactly the checks above — it never answers open questions.
• Outputs follow ../output/SKILL.md — citation by link, never restated.
