Stack check

/stack-check

What it does

Walks stack.toml, queries each declared dependency's installed version, optionally fetches the latest available version, and reports a Markdown table:

# Stack check — <YYYY-MM-DD>

| Tool | Installed | Required | Status | Update |
|------|-----------|----------|--------|--------|
| claude (Claude Code) | 2.1.89 | ≥2.1.0 | ok | — |
| codex (Codex CLI) | 0.39.0 | ≥0.40.0 | **outdated** | npm i -g @openai/codex |
| claude-leverage (this plugin) | 1.0.0 | latest 1.0.1 | **outdated** | /plugin update claude-leverage |
| git | 2.45.0 | ≥2.40.0 | ok | — |
| rg | 14.0.3 | ≥13.0.0 | ok | — |
| jq | (not found) | ≥1.6 (optional) | missing | brew install jq |
| python | 3.12.1 | ≥3.10 | ok | — |
| mmdc | (not found) | ≥10.0.0 (optional) | missing | npm i -g @mermaid-js/mermaid-cli |
| node | 20.10.0 | ≥20.0.0 | ok | — |
| shellcheck | (not found) | ≥0.8.0 (optional) | missing | brew install shellcheck |

On successful completion (no errors thrown), updates ~/.local/state/claude-leverage/.last-stack-check (or ~/.claude/claude-leverage/.last-stack-check if XDG state dir is unavailable) with the current epoch time so the SessionStart hook stays quiet for the next N days.

Workflow

1. Load stack.toml. From the plugin install dir ($CLAUDE_PLUGIN_ROOT/stack.toml) or, if running standalone, from the repo root. If neither exists, STOP and report.

2. For each [[host.tool]] and [[deps.tool]]:

   • Run check_cmd. Capture stdout+stderr.
   • Parse the version with a simple regex ((\d+\.\d+(\.\d+)?) — accept "X.Y" and "X.Y.Z" both). If parse fails or command not found, mark "missing" (and "outdated" if optional = false).
   • Compare against min_version using a tuple compare (split on .).
   • Mark: ok | outdated | missing | unknown (parse failed).
   • Resolve update hint per-OS: detect platform via uname -s (or PowerShell $env:OS / $IsWindows). Prefer update_hint_macos / update_hint_linux / update_hint_windows when present and the platform matches; otherwise fall back to the generic update_hint field. This is what stack.toml manifest_version = 2 introduced.

3. For the plugin itself:

   • Read version from the installed .claude-plugin/plugin.json.
   • WebFetch https://raw.githubusercontent.com/Filip-Podstavec/claude-leverage/main/.claude-plugin/plugin.json and compare to the installed version. Cache the network result for 24h in ~/.claude/claude-leverage/.stack-check-cache.json to avoid hammering GitHub if the user runs the skill repeatedly.

4. For Claude Code itself:

   • claude --version is the installed version.
   • We do NOT fetch the latest Claude Code version from the network — Anthropic doesn't expose a stable scrapable endpoint. Instead, the min_version in stack.toml is hand-maintained: bump it when this plugin starts depending on a feature only present in a newer CC.

5. Walk the current repo for AIDEV anchor health (if cwd is inside a git repo). Grep git rev-parse --show-toplevel for AIDEV-(TODO|QUESTION) matches and parse each line.

   Two flavors of anchor:

   • Deadline-bearing: AIDEV-TODO(by: 2026-08-01): or AIDEV-QUESTION(by: YYYY-MM-DD):. Extract the ISO-8601 date and compare against today.
     • due-soon (deadline in the next 14 days)
     • overdue (deadline already passed)
   • Age-based (no deadline): use git log -1 --format=%cI -- <file> for the file's last-modified timestamp.
     • fresh (≤30 days)
     • aging (30–90 days)
     • stale (>90 days)

   Cap walk at 5000 files; skip the bench archive, vendor dirs, node_modules, pycache, .git.

   Reported after the version table:

   ## AIDEV anchors (current repo: <name>)
   
   - 14 AIDEV-TODO total: 3 fresh, 8 aging, 2 stale (>90d), **1 overdue (by deadline)**
   - 5 AIDEV-QUESTION total: 1 fresh, 2 aging, 1 stale, 1 due-soon
   
   **Overdue (deadline passed):**
   - `src/billing/charge.py:47` — AIDEV-TODO due 2026-04-01 (44 days overdue)
     "replace the polling loop with webhooks"
   
   **Due soon (next 14 days):**
   - `src/auth/middleware.py:89` — AIDEV-QUESTION due 2026-06-05 (in 12 days)
   
   **Stale (no deadline, last touched >90 days ago):**
   - `src/legacy/handlers.py:120` — AIDEV-TODO (last touched 2025-12-03)
     "migrate to v2 API"
   

   If not in a git repo, skip this section silently.

   Deadline parsing tolerates a few formats. The distinguishing rule for implementors: the parenthesized content matches one of these regexes (anchored, case-insensitive on the keyword):

   • ^by:\s*(\d{4}-\d{2}-\d{2})$ — (by: 2026-08-01)
   • ^(\d{4}-\d{2}-\d{2})$ — (2026-08-01) (bare ISO date)
   • ^deadline:\s*(\d{4}-\d{2}-\d{2})$ — (deadline: 2026-08-01)

   Anything else in the parens (free-form notes like (Q3 2026) or (after the migration)) is NOT a deadline; that anchor falls under age-based stale tracking. This prevents misclassifying ambiguous parenthetical text as a date.

6. Sanity-check AGENTS.md (if present in cwd or repo root):

   • File size, two tiers (report the size either way):
     • warn over 8 KiB — lean target exceeded; an always-loaded file this large dilutes attention. Suggest extracting topic depth to docs/ behind a when-to-read link.
     • flag over 32 KiB — Codex caps the assembled project doc at project_doc.max_bytes (default 32768) and silently drops the rest, so content past that byte is invisible to Codex agents. Both tiers are advisory here and do not stop the timestamp reset (step 9). /repo-doctor escalates the 32 KiB tier to a hard ❌ — that split is intentional (see ADR 0009): /stack-check informs, /repo-doctor gates.
   • Broken @<path> imports: grep for ^@ lines, verify each referenced file exists relative to the importer.
   • Stale file references: extract path/to/file.ext-shaped strings from the body and check existence (best-effort; lots of false positives, so report only the obvious ones — e.g. when AGENTS.md mentions scripts/foo.sh and scripts/foo.sh does not exist). Per-directory AGENTS.md files (**/AGENTS.md, depth ≤ 3) get the same two-tier size check — and they share the same ~32 KiB Codex budget as the root file, so a large root plus several per-dir files can truncate even when no single file exceeds the cap.

   Reported after the anchors section:

   ## AGENTS.md sanity
   
   - `AGENTS.md` — 11.3 KiB, **over 8 KiB lean target** (extract topic
     depth to `docs/` behind a when-to-read link)
   - `src/billing/AGENTS.md` — 1.1 KiB, ok
   - `src/api/AGENTS.md` — **38.4 KiB, over Codex 32 KiB cap** (Codex
     will silently drop content beyond byte 32768; split it)
   - Broken imports: _none_
   - Possibly stale references: 1 (`scripts/old_runner.sh` mentioned
     but not found)
   

7. Walk every tracked *.md file for stale path references. This is the generalization of step 6's "Possibly stale references" check beyond AGENTS.md — the failure mode "doc references a file that was moved or deleted N versions ago" is repo-wide, not AGENTS.md-only.

   Scope:

   • Use git ls-files '*.md' so untracked / .gitignored markdown is not scanned. Skip files under the bench archive, node_modules/, vendor/, __pycache__/, .git/, and anything inside a .gitignored tree (relying on ls-files filters most of this).
   • Cap walk at the first 200 markdown files (sorted) — repos with larger doc trees get a "(truncated)" footer; honest scope, not a silent half-job.

   Per file:

   • Strip fenced code blocks (``` ... ```) and inline backticks before regex-walking the body. Path-like tokens inside code blocks are usually placeholders / examples, not live links.
   • Extract candidates with a deliberately conservative regex (rough shape, implementor adjusts): (?:^|[\s(\[>])([a-zA-Z][a-zA-Z0-9_.-]*(?:/[a-zA-Z0-9_.-]+)+.[a-zA-Z0-9]+)(?:$|[\s.,;:)\]]) — must contain at least one /, must end in a file extension, must not look like a URL (skip if preceded by :// or starting with http).
   • Skip tokens that look like commit hashes, version strings (v1.2.3), or domain names (anything matching \.(com|org|io|dev|gov)$).
   • Resolve relative to the repo root (git rev-parse --show-toplevel). If the file does not exist, record <md-file>:<line> → <token>.

   Output budget: hard cap of 20 broken refs in the report; if more, show the first 20 plus a "(N more not shown)" footer so the section does not dominate the report.

   Reported as a new section:

   ## Markdown link audit
   
   Scanned 47 tracked `*.md` files; 3 broken path references.
   
   - `README.md:118` → `scripts/legacy/runner.sh` (not found)
   - `docs/adr/0002-...md:42` → `agents/old-reviewer.md` (not found)
   - `workflows/security-first-feature.md:88` → `templates/old-logging.md` (not found)
   

   If zero broken refs, write _All links resolve._ and move on. If the scan was skipped (not in a git repo, or CLAUDE_LEVERAGE_SKIP_MD_LINK_AUDIT=1), omit the section entirely.

   This check exists because the v1.0.0 → v1.3.3 pivot in this repo left three stale tests/README.md / AGENTS.md / ci.yml refs that survived 4–7 version bumps before being caught by a human-led pre-push audit. Catching that class of drift automatically is the point.

8. Emit the Markdown report combining version table + anchors + AGENTS.md sanity + markdown link audit. Tier the version rows: required first, then optional. Required-failing rows in bold.

9. Reset the timestamp. Only if no row failed with an error (process crashed, network exception). A failure status (outdated / missing / stale anchors / oversized AGENTS.md) is information, not an error — reset the timestamp.

   Run exactly this command — do NOT write a literal number into the file:

   date +%s > "$STATE_DIR/.last-stack-check"
   

   where $STATE_DIR is ${CLAUDE_LEVERAGE_STATE_DIR:-${XDG_STATE_HOME:-$HOME/.local/state}/claude-leverage} (matching the fallback chain in scripts/hooks/stack-freshness.sh). The SessionStart hook reads the epoch from the file body — not the mtime — so a stale or hallucinated number suppresses nudges for weeks. Capturing the value via date +%s is the only reliable way to avoid the v1.4.0 field-feedback #7 bug where the body and mtime disagreed by ~2 months.

Hard rules

• Never install anything. Output update commands, but never run them. The user types whichever they want.
• Never block. Read-only network + filesystem.
• Cache network results for 24h. If the cache file exists and is fresh, use it without hitting the network. Cache key: the fully-resolved marketplace.json URL.
• Network is optional. If WebFetch fails (offline), report "(cannot fetch latest — offline)" for the rows that need network and keep the rest of the report.
• Always run Bash(... --version) defensively. Use 2>&1 and treat exit code != 0 OR empty output as "not found".

Tunables

• CLAUDE_LEVERAGE_FRESHNESS_DAYS=N — override the 30-day default for the SessionStart hook.
• CLAUDE_LEVERAGE_FRESHNESS_DAYS=0 — disable the SessionStart nudge entirely.
• CLAUDE_LEVERAGE_STATE_DIR=<path> — override the state directory.
• CLAUDE_LEVERAGE_ANCHOR_STALE_DAYS=N — change the "stale" threshold for AIDEV-TODO/QUESTION (default 90).
• CLAUDE_LEVERAGE_SKIP_ANCHOR_AUDIT=1 — skip the AIDEV anchor walk entirely (useful when running outside any project repo).
• CLAUDE_LEVERAGE_SKIP_AGENTS_MD_AUDIT=1 — skip the AGENTS.md sanity pass.
• CLAUDE_LEVERAGE_SKIP_MD_LINK_AUDIT=1 — skip the repo-wide markdown link audit (step 7). Use when the repo has a very large doc tree and the audit is producing too many false positives to be useful.

Codex parity

Same SKILL.md ships in Codex via scripts/install-codex.sh. The skill checks Codex's own version too (if codex is on PATH); the row is optional so a Claude-only user doesn't see a false missing.

What this skill does NOT do

• Install or update anything. Suggest commands; let the user run them.
• Check arbitrary user-installed plugins. Scope is limited to this plugin's own stack. Policing every other plugin's freshness is scope creep with bad failure modes (marketplaces change shape, plugins uninstall, etc.).
• Telemetry / phone-home. All state is local. Only network calls are to public GitHub and (optionally) npm registry for plugin/codex latest-version lookup, and only when the user explicitly runs this skill.
