description	Diagnostic check for the ark-skills v2 invariants — routing-destination ecosystems, the 6-skill roster, OKF conventions, GitHub-Issues conventions, and NotebookLM recall

Ark Health Check

Run the v2 invariant checks across the Ark ecosystem and produce a scored report with actionable fix instructions. This skill diagnoses and recommends only — all fixes go through /ark-onboard.

ark-skills v2 is two co-equal cores: a workflow consultant (/ark-consult) that routes each task to one of four execution ecosystems, and a conventions layer (/ark-onboard, /ark-health, /ark-update, /vault, /notebooklm-vault) that converges projects onto OKF knowledge bundles + GitHub-Issues task management. The checks below verify both cores are healthy.

Context-Discovery Exemption

This skill is exempt from normal context-discovery. It must work when CLAUDE.md is missing, broken, or incomplete. When CLAUDE.md is absent:

• Ecosystem checks (1–4) and Repo & Skills checks (5–6) run normally
• OKF / GitHub / NotebookLM checks that need the vault root report "cannot check — CLAUDE.md missing" instead of failing silently

Never abort early. Run all checks regardless of earlier failures.

Required CLAUDE.md fields (v2)

• Project name — any string (header or table)
• Vault root — path to the OKF bundle (e.g. vault/)

Task tracking is GitHub Issues (no task-prefix / counter fields — those were retired with TaskNotes).

Diagnostic Checklist

Ecosystems — the consultant's routing destinations (Checks 1–4)

Detection is session-capability: read the system-reminder skill list in the current session and match for the listed skill names. Never inspect ~/.claude/plugins/ for plugin presence.

Check 1 — superpowers plugin | Tier: Critical

• Detect: session-list contains any superpowers:* entry (e.g. superpowers:brainstorming, superpowers:systematic-debugging)
• Pass: ≥1 match
• Fail action: /plugin install superpowers@claude-plugins-official (marketplace: anthropics/claude-plugins-official)
• Why Critical: it is a primary routing destination (hard debugging, TDD, refactors, plans)

Check 2 — gstack plugin | Tier: Standard

• Detect: session-list contains any of browse, qa, ship, review, design-review
• Pass: ≥1 match
• Fail action: run /ark-onboard (installs gstack for claude + codex)
• Unlocks: gstack routing (spec/ship/investigate/design/docs)

Check 3 — mattpocock skills installed | Tier: Standard

• Detect (filesystem — these skills declare disable-model-invocation: true, so they never appear as ambient session triggers): req=0; for s in to-tickets setup-matt-pocock-skills; do [ -d "$HOME/.claude/skills/$s" ] && req=$((req+1)); done opt=0; for s in to-spec triage implement; do [ -d "$HOME/.claude/skills/$s" ] && opt=$((opt+1)); done { [ "$req" -eq 2 ] && [ "$opt" -ge 2 ]; } && echo "PASS: to-tickets+setup present, $opt/3 optional" || echo "FAIL: req=$req/2 opt=$opt/3"
• Pass: to-tickets + setup-matt-pocock-skills present, plus ≥2 of to-spec/triage/implement
• Fail action: npx skills@latest add mattpocock/skills, then /setup-matt-pocock-skills
• Unlocks: /to-tickets + /triage issue machinery and mattpocock as a routing destination

Check 4 — oh-my-claudecode (OMC) | Tier: Standard | Upgrade-style (never fails)

• Detect: command -v omc OR ~/.claude/plugins/cache/omc exists; ARK_SKIP_OMC=true overrides to skip
• Pass: OMC present
• Upgrade action: install at https://github.com/anthropics/oh-my-claudecode — unlocks OMC routing (autopilot / ultrawork / team / autoresearch)

---

Repo & Skills (Checks 5–6)

Check 5 — exactly 6 skills | Tier: Critical

n=$(find skills -mindepth 1 -maxdepth 1 -type d ! -name shared | wc -l | tr -d ' ')
want="ark-consult ark-health ark-onboard ark-update notebooklm-vault vault"
got=$(find skills -mindepth 1 -maxdepth 1 -type d ! -name shared -exec basename {} \; | sort | tr '\n' ' ')
[ "$n" = "6" ] && echo "PASS: 6 skills ($got)" || echo "FAIL: $n skill dirs — expected 6: $want"

• Pass: exactly 6 skill directories under skills/ (ark-consult, ark-health, ark-onboard, ark-update, notebooklm-vault, vault), plus shared/ + AGENTS.md
• Fail action: a v1 skill lingered through the delete phase, or a new one was added — reconcile against the roster

Check 6 — plugin manifest freshness | Tier: Standard | Warn-only

rg -q "consultant" .claude-plugin/plugin.json && rg -q "okf" .claude-plugin/plugin.json \
  && echo "PASS: manifest carries the v2 identity (consultant, okf, …)" \
  || echo "WARN: plugin manifest not refreshed to the v2 identity"

• Pass: .claude-plugin/{plugin,marketplace}.json description/keywords carry the v2 identity (consultant, routing, okf, github-issues, …) and no retired-skill names
• Warn: refresh the keywords/description arrays (there is no skill list to maintain — skills auto-discover from skills/)

---

OKF Conventions (Checks 7–12)

Need the vault root from CLAUDE.md (default vault/). If CLAUDE.md is missing, report "cannot check".

Check 7 — CLAUDE.md exists | Tier: Critical

• Pass: CLAUDE.md in project root
• Fail action: create it with the two required fields above

Check 8 — Python 3.10+ | Tier: Critical

v=$(python3 --version 2>/dev/null | grep -oE '[0-9]+\.[0-9]+' | head -1)
python3 -c "import sys; sys.exit(0 if sys.version_info>=(3,10) else 1)" 2>/dev/null \
  && echo "PASS: Python $v" || echo "FAIL: need Python >= 3.10 (have '$v')"

• Fail action: install Python 3.10+ (macOS: brew install python@3.12) — required for the OKF tooling

Check 9 — OKF tooling present | Tier: Critical

d="${VAULT_ROOT:-vault}/_meta/okf"
for f in okf_lint.py okf_cli.py convert_links.py normalize_frontmatter.py; do
  [ -f "$d/$f" ] || { echo "FAIL: missing $d/$f"; MISS=1; }
done; [ -z "$MISS" ] && echo "PASS: OKF tooling present"

• Pass: _meta/okf/ holds okf_lint.py, okf_cli.py, convert_links.py, normalize_frontmatter.py, and _meta/generate-index.py exists
• Fail action: run /ark-onboard to copy the OKF tooling into the bundle

Check 10 — OKF lint clean | Tier: Critical

python3 "${VAULT_ROOT:-vault}/_meta/okf/okf_lint.py" --quiet; rc=$?
[ "$rc" = "0" ] && echo "PASS: okf_lint 0 errors" || echo "FAIL: okf_lint exit $rc"

• Pass: okf_lint.py --quiet exits 0 (warnings are allowed; errors are not)
• Fail action: fix the reported errors (usually a wikilink that should be a relative link, a missing description, or a malformed timestamp)

Check 11 — okf_version declared | Tier: Critical

grep -q 'okf_version: *"0.1"' "${VAULT_ROOT:-vault}/index.md" \
  && echo "PASS: okf_version 0.1" || echo "FAIL: bundle index.md missing okf_version"

• Pass: the bundle root index.md declares okf_version: "0.1"
• Fail action: run /ark-onboard OKF init or add the frontmatter key

Check 12 — index fresh | Tier: Standard | Warn-only

• Pass: index.md exists and no page is newer than it
• Warn: pages modified since generation — refresh: python3 ${VAULT_ROOT:-vault}/_meta/generate-index.py
• Fail: index.md absent

GitHub Issues Conventions (Checks 13–16)

Check 13 — gh CLI installed + authenticated | Tier: Standard

command -v gh >/dev/null 2>&1 && gh auth status >/dev/null 2>&1 \
  && echo "PASS: gh authed" || echo "FAIL: gh missing or not authenticated"

• Fail action: install gh and run gh auth login

Check 14 — label taxonomy present | Tier: Standard

have=$(gh label list --limit 100 2>/dev/null | cut -f1)
for l in needs-triage epic P1 consultant conventions vault onboarding; do
  echo "$have" | grep -qx "$l" || { echo "FAIL: missing label '$l'"; MISS=1; }
done; [ -z "$MISS" ] && echo "PASS: triage+type+priority+component families present"

• Pass: triage (needs-triage…), type (epic/story/task), priority (P1–P3), and component (consultant/conventions/vault/onboarding) labels exist
• Fail action: run /ark-onboard label bootstrap block

Check 15 — docs/agents config present | Tier: Standard

for f in issue-tracker triage-labels domain; do
  [ -f "docs/agents/$f.md" ] || { echo "FAIL: missing docs/agents/$f.md"; MISS=1; }
done; [ -z "$MISS" ] && echo "PASS: docs/agents present"

• Pass: docs/agents/{issue-tracker,triage-labels,domain}.md exist (written by /setup-matt-pocock-skills + the ark additions)
• Fail action: run /setup-matt-pocock-skills on this repo

Check 16 — frozen trackers frozen | Tier: Standard

tn="${VAULT_ROOT:-vault}/TaskNotes"; sl="${VAULT_ROOT:-vault}/Session-Logs"
ok=1
grep -rql "FROZEN" "$tn" 2>/dev/null || { echo "WARN: TaskNotes missing FROZEN banner"; ok=0; }
grep -rql "FROZEN" "$sl" 2>/dev/null || { echo "WARN: Session-Logs missing FROZEN banner"; ok=0; }
[ "$ok" = 1 ] && echo "PASS: legacy trackers frozen, no automation targets them"

• Pass: TaskNotes/ and Session-Logs/ carry FROZEN banners; no surviving skill/script writes to them (the active work record is GitHub Issues + log.md)
• Warn action: run /ark-onboard to (re-)apply the freeze banners

---

NotebookLM Recall (Checks 17–19)

Check 17 — NotebookLM CLI installed | Tier: Full | Upgrade-style

command -v notebooklm >/dev/null 2>&1 && echo "PASS" || echo "UPGRADE: notebooklm not installed"

• Upgrade action: pipx install notebooklm-cli — unlocks synthesized recall via /notebooklm-vault

Check 18 — NotebookLM config reachable | Tier: Full | Requires Check 17

{ [ -f .notebooklm/config.json ] || [ -f "${VAULT_ROOT:-vault}/.notebooklm/config.json" ]; } \
  && echo "PASS: config found" || echo "FAIL: no .notebooklm/config.json (project or vault root)"

• Pass: .notebooklm/config.json present (project root or vault root) with a notebook ID
• Fail action: run /notebooklm-vault setup

Check 19 — NotebookLM authenticated | Tier: Full | Requires Check 17

notebooklm auth check --test >/dev/null 2>&1 && echo "PASS: authenticated" || echo "FAIL: auth check failed"

• Fail action: notebooklm auth login, then rerun /ark-health

Vault-awareness Convention (Check 20)

Check 20 — vault-awareness region + reminder hook | Tier: Standard | Warn-only | Requires Check 7

# (a) managed region present in CLAUDE.md
grep -q 'ark:begin id=vault-awareness' CLAUDE.md 2>/dev/null && b=OK || b=MISSING
# (b) reminder hook installed: script executable AND registered in settings.json Stop
{ [ -x .claude/hooks/ark-vault-reminder-hook.sh ] \
  && grep -q 'ark-vault-reminder-hook.sh' .claude/settings.json 2>/dev/null; } && h=OK || h=MISSING
{ [ "$b" = OK ] && [ "$h" = OK ]; } && echo "PASS" || echo "WARN: block=$b hook=$h"

• Pass: the vault-awareness managed region is in CLAUDE.md and the reminder hook is executable + registered.
• Warn action: run /ark-update (converges the block) and /ark-onboard Block C.2 (installs the hook). Warn-only — does not demote the health tier.

---

Workflow

1. Run all checks in sequence. Do not abort on failure.
   • Checks needing the vault root: if Check 7 failed (CLAUDE.md missing), record skip with "cannot check — CLAUDE.md missing".
   • Checks 18, 19: if Check 17 failed, record skip with "requires NotebookLM CLI (check 17)".
2. Classify each result:

Symbol	Outcome	Condition
OK	Pass	Check passed
!!	Fail	Check failed — has a fix instruction
~~	Warning	Non-blocking (Check 6 manifest, Check 12 index staleness, Check 16 banner, Check 20 vault-awareness)
--	Available upgrade	Feature not installed, above current tier (Check 4 OMC, Check 17 NotebookLM CLI)

3. Assign tier from the highest level where no Critical or Standard check fails. Warn/skip/upgrade never demote tier.

   • Minimal: no fail in ecosystem + repo checks (1–6)
   • Quick: no fail in 1–12 (OKF conventions healthy)
   • Standard: no fail in 1–16 (GitHub-Issues conventions in place)
   • Full: no fail in 1–19 (NotebookLM recall reachable)

4. Emit scorecard per the Output Format. Always end with Run /ark-onboard to fix or upgrade.

Run /ark-onboard to fix or upgrade

Rules:

• Always show all 5 section headers (Ecosystems, Repo & Skills, OKF Conventions, GitHub Issues, NotebookLM)
• Never omit a check — skipped checks render as -- {name} -- cannot check (CLAUDE.md missing)
• !! → indented Fix: line; ~~ → indented Refresh:/Fix:; -- → indented Unlock: + Install:
• Singular/plural: 1 fix, not 1 fixes
• Always end with: Run /ark-onboard to fix or upgrade

Design Decisions

• No auto-fix. /ark-health diagnoses and recommends only. All fixes go through /ark-onboard.
• Authoritative check definitions. This skill is the source of truth for the v2 invariant checks. If /ark-onboard's copy drifts from here, this file wins.
• Session-based plugin detection. Ecosystems are detected by whether their skills appear in the current session — never by inspecting ~/.claude/plugins/. mattpocock is the exception (its skills are disable-model-invocation, so it is detected on the filesystem).
• Graceful degradation. Never abort on CLAUDE.md absence. Report clearly and continue.
• Two-core invariants. The checks map directly to the v2 acceptance criteria: the consultant's four routing destinations, the 6-skill roster, an OKF-clean bundle, the GitHub-Issues convention layer, and NotebookLM recall.
