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 5.1 | $0.00016 | $0.00410 |
| Opus 5 | $0.00008 | $0.00205 |
| Sonnet 5 | $0.00003 | $0.00082 |
| Haiku 4.5 | $0.00002 | $0.00041 |
Grade A, and why
light-review-existing-diffs 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 9d 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
Overview
Quick review of existing diffs without full PR context. Full workflow: .cursor/skill-contracts/light-review-existing-diffs/SKILL.md (user install: ~/.cursor/skill-contracts/light-review-existing-diffs/SKILL.md).
Defaults
None. See skill for workflow defaults.
Steps
- Read
.cursor/skill-contracts/light-review-existing-diffs/SKILL.mdfor the full agent contract; if that file is missing, read~/.cursor/skill-contracts/light-review-existing-diffs/SKILL.md. - Execute the workflow in order; do not skip safety steps.
- Report outcomes per skill (summary, tables, or checklist as specified).
Anti-patterns
- Do not block on nitpicks. Trigger: a quick pass that surfaces minor style or preference issues. Wrong: holding up the change over cosmetic nits. Correct: note nits as optional and let the change proceed. Reason: a light review is meant to be fast, so blocking on cosmetics defeats its purpose.
- Flag security issues even in a light review. Trigger: spotting a security risk during a quick pass. Wrong: skipping it because the review is meant to be light. Correct: surface the security concern regardless of review depth. Reason: a missed vulnerability is costly no matter how quick the pass was.

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.
