Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00032 | $0.00722 |
| Opus 5 | $0.00016 | $0.00361 |
| Sonnet 5 | $0.00006 | $0.00144 |
| Haiku 4.5 | $0.00003 | $0.00072 |
Grade A, and why
grace-cli 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 8d 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.
What it actually says
<command_run_contract>
--run-commands executes each declared MustPassCommand value once per lint, fail-fast, with a default 600s per-command timeout (--command-timeout SECONDS overrides, 0 disables). Plan, progress, and per-command result lines go to stderr; the lint report and JSON go to stdout, so piping stdout stays safe. Agents and pipes get compact output by default; interactive terminals see live streamed command output. Force modes with --verbose (live) or --quiet (compact); they are mutually exclusive, and --format json is always compact. Full combined output of every command is stored per run under ~/.cache/grace/run-commands/<project>/runs/<run>/ (respecting XDG_CACHE_HOME) with a machine-readable meta.json; failing commands print a bounded output tail plus the absolute log path. Interrupted runs (SIGINT/SIGTERM) kill the whole command process group, record interrupted status in meta.json, and exit 130.
</command_run_contract>
<lifecycle_command_contract>current evaluates active approved baselines and is not end-state evidence. Keep MustPassCommand entries as leaf project checks; do not nest grace lint, grace status, or another GRACE lifecycle command inside plan assertions. Run selected target/final lint externally.</lifecycle_command_contract>
<failure_contract>
Lint, status, and navigation commands validate before returning records. JSON argument/runtime failures are one { "schemaVersion": "1.0.0", "ok": false, "error": { ... } } object on stdout. Text failures are one concise actionable line with a nonzero exit code and no stack trace.
</failure_contract>
<runtime_contract>
TypeScript/JavaScript analysis is bundled. Python and Dart governed files require their runtimes on PATH; missing runtimes fail closed with actionable analysis.runtime-missing diagnostics instead of silently dropping parity checks.
</runtime_contract>
<migration_boundary>GRACE 4 commands do not dual-validate legacy GRACE 3 docs. Use grace-migrate.</migration_boundary>
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.

grace-cli is a skill published in the GitHub repository osovv/grace-marketplace (240 stars, last pushed 4d ago), licensed MIT. It adds 32 tokens to every session and 722 once invoked, about $0.0002 per session on Opus 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 2026-08-30.
