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 | $0.00013 | $0.00077 |
| Opus 5 | $0.00006 | $0.00039 |
| Sonnet 5 | $0.00003 | $0.00015 |
| Haiku 4.5 | $0.00001 | $0.00008 |
Grade A, and why
review-diff 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.
What it actually says
Review the current git diff.
git diffto read the change.- Report only high-confidence findings as
file:line — issue — fix. - Separate bugs from nits.
- End with APPROVE or REQUEST-CHANGES and a one-line reason.
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.

review-diff is a command published in the GitHub repository ruvnet/metaharness (624 stars, last pushed 2d ago), licensed MIT. It adds 13 tokens to every session and 77 once invoked, about $0.0001 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.
Other commands, from other repositories
prepare-this-repo
Prepare the current repository to abcd's working conventions — audit it against the abcd record, then adopt the three-tier .abcd/ layout, an AGENTS.md conventions section, and the commit gates. Interim bridge until abcd manages repos directly. Use when the user asks to prepare, onboard, scaffold, or bootstrap a repo…
intent
Press-release intent lifecycle — status, quoted-text create, the implement-readiness gate, and the human planning interview that turns a draft into a planned, specced intent.
ideate
Put a big, unproven idea through the three-leg admission gauntlet — primary-source research, a grill against the existing record, and an independent adversarial review — then record the verdict, whether the idea survives or dies.
history
Manage the native session-transcript store for this repo by invoking the abcd binary. list, show and staged are read-only; capture and drain are the redacting write paths. The store is keyed on the repo's root-commit SHA and every stored transcript is redacted on write.
memory
Query and curate the per-project memory substrate at .abcd/memory/ by invoking the abcd binary. Bare invocation is a read-only status render; ingest/ask/lint curate, synthesise, and health-check the store.
nio
Nio — scan code, evaluate an action, read the audit report, manage config.
