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 | $0.00000 | $0.00388 |
| Opus 5 | $0.00000 | $0.00194 |
| Sonnet 5 | $0.00000 | $0.00078 |
| Haiku 4.5 | $0.00000 | $0.00039 |
Grade A, and why
prp-core-commit 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
Create Git Commit
Create an atomic git commit with a properly formatted commit message following best practices for the uncommited changes or these specific files if specified.
Specific files (skip if not specified):
- File 1: $1
- File 2: $2
- File 3: $3
- File 4: $4
- File 5: $5
Instructions
Commit Message Format:
- Use conventional commits:
<type>: <description> - Types:
feat,fix,docs,style,refactor,test,chore - Present tense (e.g., "add", "fix", "update", not "added", "fixed", "updated")
- 50 characters or less for the subject line
- Lowercase subject line
- No period at the end
- Be specific and descriptive
Examples:
feat: add web search tool with structured loggingfix: resolve type errors in middlewaretest: add unit tests for config moduledocs: update CLAUDE.md with testing guidelinesrefactor: simplify logging configurationchore: update dependencies
Atomic Commits:
- One logical change per commit
- If you've made multiple unrelated changes, consider splitting into separate commits
- Commit should be self-contained and not break the build
IMPORTANT
- NEVER mention claude code, anthropic, co authored by or anything similar in the commit messages
Run
- Review changes:
git diff HEAD - Check status:
git status - Stage changes:
git add -A - Create commit:
git commit -m "<type>: <description>"
Report
- Output the commit message used
- Confirm commit was successful with commit hash
- List files that were committed
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.

prp-core-commit is a command published in the GitHub repository mort-lab/excel-mcp (5 stars, last pushed 25d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 388 tokens. 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.
