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 | $0.00015 | $0.00292 |
| Opus 5.5 | $0.00006 | $0.00117 |
| Sonnet 5.5 | $0.00003 | $0.00058 |
| Haiku 4.5 | $0.00002 | $0.00029 |
Grade A, and why
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 1mo 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
Analyze branch diff: $ARGUMENTS
Pre-loaded context
Branch: !git branch --show-current
Merge base: !git merge-base main HEAD 2>/dev/null || echo "N/A"
Instructions
⚠️ CRITICAL: Always use merge-base, never bare git diff main
# CORRECT — only shows YOUR changes
git diff $(git merge-base main HEAD)..HEAD
# WRONG — includes main's forward progress as noise
git diff main
Determine action from arguments:
| Argument | Action |
|---|---|
stat or (empty) |
git --no-pager diff $(git merge-base main HEAD)..HEAD --stat |
full |
git --no-pager diff $(git merge-base main HEAD)..HEAD |
files |
git --no-pager diff $(git merge-base main HEAD)..HEAD --name-only |
commits |
git --no-pager log $(git merge-base main HEAD)..HEAD --oneline |

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.

diff is a command published in the GitHub repository brain-bootstrap/claude-code-brain-bootstrap (11 stars, last pushed 5mo ago), licensed MIT. It adds 15 tokens to every session and 292 once invoked, about $0.0001 per session on Opus 5.5. 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.
