Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00070 | $0.01655 |
| Opus 5.5 | $0.00028 | $0.00662 |
| Sonnet 5.5 | $0.00014 | $0.00331 |
| Haiku 4.5 | $0.00007 | $0.00166 |
Grade C, and why
standardize scanned grade C with 1 finding 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 1mo 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.
Harvests environment variableshighData exfiltration
Enumerating or grepping the environment for keys collects credentials unrelated to what the mod says it does.
- ALL subprocess calls MUST use `env -u CLAUDECODE` (or set `env={k: v for k, v in os.environ.items() if k != "CLAUDECODE"}` in Python). Without this the SDK hangs on file ops. Reference: `acp` skill, "Critical: Strip CL How it starts
The opening of the file, as written. The whole thing — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Standardize Journal Entries
The journal-tools check validator flags three failure modes:
- Standard over target - body > 150 words, no
[Extended]marker → either depth is real (add marker) or body is inflated (condense). - Extended over max - body > 400 words even with
[Extended]marker → condense, marker can stay. (Alternative when the depth is worth preserving:/journal:article Nextracts the body intodocs/<slug>.mdand slims the entry to a summary + link.) - Spurious marker -
[Extended]present but body < 150 words → marker is false advertising → drop it.
This command repairs all three via the ACP companion-process pattern: a shipped prompt YAML at src/stellars_claude_code_plugins/journal/prompts/standardize.yaml defines the per-entry rubric, the CLI renders it for one entry at a time, a fresh claude -p subprocess returns a structured decision, the CLI applies it. Run after a journal-tools check reports warnings; never inline-edit oversized entries by hand.
Pre-flight install (MANDATORY, no asking)
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.
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.

standardize is a skill published in the GitHub repository stellarshenson/claude-code-plugins (4 stars, last pushed 2d ago), licensed MIT. It adds 70 tokens to every session and 1,655 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it C with 1 finding (harvests environment variables). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
