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 | $0.00240 | $0.00240 |
| Opus 5 | $0.00120 | $0.00120 |
| Sonnet 5 | $0.00048 | $0.00048 |
| Haiku 4.5 | $0.00024 | $0.00024 |
Grade A, and why
claude-code-starter-kit review.instructions.md 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 2d 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
When reviewing changes in this repository, explicitly check upgrade-path coverage in addition to fresh-install behavior.
If a pull request adds or changes a feature flag, setup prompt, generated file, profile default, hook, command, settings key, or any other user-visible setup behavior, review whether existing installs are upgraded correctly through setup.sh --update and /update-kit.
Look for cases where a new key is added for fresh installs but older saved config, manifests, or deployed files would silently miss the new behavior. Missing keys on older installs should receive the intended default for that profile, but explicit user choices that already exist must not be overwritten.
Also review whether user-facing documentation was updated in the same pull request when needed. Check for missing updates to:
CHANGELOG.mdfor user-visible behavior changes, new defaults, upgrade behavior changes, or new commandsREADME.mdandREADME.en.mdfor setup flow, defaults, CLI flags, or prerequisites- files under
docs/when configuration mapping, feature behavior, or upgrade behavior changed
If these update-path or documentation concerns are missing, call them out as review findings instead of assuming they can be handled later.
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.
