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.

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 | $0.00029 | $0.01562 |
| Opus 5 | $0.00015 | $0.00781 |
| Sonnet 5 | $0.00006 | $0.00312 |
| Haiku 4.5 | $0.00003 | $0.00156 |
Grade A, and why
cantonal 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 today.
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 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.

Other commands, from other repositories
launch
Preview the public launch — the file bundle, the secret/PII scan, and the release gates — in dry-run mode, cut a release by deriving its version and composing its changelog, and scaffold the changelog-driven release gate into a managed repo. The preview performs zero writes; ship writes the dated CHANGELOG heading and…
disembark
Pack a lifeboat from a repository into a destination directory — read-only over the source, behind a destination safety gate, secret-scanned before any write. Point it at any repo (including a dead or archived one) and write the lifeboat elsewhere.
banlist
Maintain the two banned-names layers — the committed CI-enforced public list and the gitignored per-machine private list — by invoking the abcd binary. Bare invocation is a read-only render; add/remove act on one named layer.
capture
Capture issues to the structured per-repo ledger and query them, by invoking the abcd binary. Bare invocation is a read-only status render; list/promote/resolve/wontfix act on the ledger.
identity
Show this repo's canonical identity block — title, tagline, pitch — and every rendered surface held to it, and print the proposed correction for any that drifted, by invoking the abcd binary. The bare and render forms perform zero writes; init records the block and the pointer to it.
version
Print the installed abcd version, install mode, and vintage by invoking the abcd binary. Read-only unless --check is passed.
