Written for Claude Code: allowed-tools in frontmatter. Also seen: mentions .claude-plugin.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

archive scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Archive Journal

Prefer the programmatic tool. It preserves numbering and appends idempotently.

Pre-flight install (MANDATORY, no asking)

Before invoking journal-tools archive, always run:

python3 -m pip install --user --upgrade stellars-claude-code-plugins 2>&1 | tail -1
LIB=$(python3 -c "import importlib.metadata as m;print(m.version('stellars-claude-code-plugins'))" 2>/dev/null) || { echo "FATAL: toolkit unavailable"; exit 1; }
PLUG=$(grep -m1 '"version"' "${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json" 2>/dev/null | cut -d'"' -f4)
OLDER=$(printf '%s\n%s\n' "$LIB" "$PLUG" | sort -V | head -1)
[ -n "$PLUG" ] && [ "$LIB" != "$PLUG" ] && [ "$OLDER" = "$LIB" ] && { echo "STALE: library $LIB older than plugin $PLUG - refusing to run on an outdated CLI; re-run the upgrade"; exit 1; }
echo "toolkit $LIB"

Run the CLI without touching the caller's project. The gate above puts it on PATH, so the bare command name is the whole invocation. uv run instead resolves whatever project the working directory sits in and writes uv.lock and .venv into it, so if you reach for uv pass --no-project (uv run --no-project <cli> ...) - it skips project discovery, leaves the tree untouched and still finds the same PATH binary. --no-sync and --frozen are not substitutes; both still create .venv.

The upgrade always runs - a stale-but-importable install is exactly the failure this gate prevents, and the reinstall also repairs a stale shim on PATH whose package is uninstalled in the active Python. Never skip. Never ask.

Primary path (programmatic)

journal-tools archive .claude/JOURNAL.md

Default: threshold 40, keep last 20. Flags: --keep-last N, --threshold N, --archive-path PATH. If uv not available, try plain journal-tools archive ... or python -m stellars_claude_code_plugins.journal.journal_tools archive ....

After run:

  1. Read .claude/JOURNAL.md last 5 lines — confirm last 20 entries remain, note at top links to archive
  2. Read JOURNAL_ARCHIVE.md beside the real journal file (.agents/JOURNAL_ARCHIVE.md, Layout in skills/journal/SKILL.md) last 5 lines — confirm entries appended, numbering continuous
  3. Run journal-tools check .claude/JOURNAL.md — exit 0 = clean

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

archive is a skill published in the GitHub repository stellarshenson/claude-code-plugins (4 stars, last pushed 2d ago), licensed MIT. It adds 45 tokens to every session and 857 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
