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 | $0.00010 | $0.00342 |
| Opus 5 | $0.00005 | $0.00171 |
| Sonnet 5 | $0.00002 | $0.00068 |
| Haiku 4.5 | $0.00001 | $0.00034 |
Grade A, and why
revise-claude-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 10d 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 this session for learnings about working with Antigravity in this codebase. Update GEMINI.md with context that would help future Gemini sessions be more effective.
Step 1: Reflect
What context was missing that would have helped Gemini work more effectively?
- Bash commands that were used or discovered
- Code style patterns followed
- Testing approaches that worked
- Environment/configuration quirks
- Warnings or gotchas encountered
Step 2: Find GEMINI.md Files
find . -name "GEMINI.md" -o -name ".gemini.local.md" 2>/dev/null | head -20
Decide where each addition belongs:
GEMINI.md- Team-shared (checked into git).gemini.local.md- Personal/local only (gitignored)
Step 3: Draft Additions
Keep it concise - one line per concept. GEMINI.md is part of the prompt, so brevity matters.
Format: <command or pattern> - <brief description>
Avoid:
- Verbose explanations
- Obvious information
- One-off fixes unlikely to recur
Step 4: Show Proposed Changes
For each addition:
### Update: ./GEMINI.md
**Why:** [one-line reason]
\`\`\`diff
+ [the addition - keep it brief]
\`\`\`
Step 5: Apply with Approval
Ask if the user wants to apply the changes. Only edit files they approve.
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.

revise-claude-md is a command published in the GitHub repository ronmkr/PromptBook (2 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 10 tokens to every session and 342 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 2026-08-31.
