caliber-pre-commit

A commit rule for Caliber, a tool that synchronizes coding-agent configuration files.

In plain words
What is it for?
Use it whenever you are about to commit changes in a repository that uses Caliber, so agent instructions and configuration stay updated.
Why use it?
It checks whether the repository’s pre-commit hook will perform the synchronization automatically. If not, it refreshes and stages the relevant configuration files before a commit.

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.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

caliber-pre-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 yesterday.

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

Before every git commit, check if the Caliber pre-commit hook is installed: Run: grep -q "caliber" .git/hooks/pre-commit 2>/dev/null && echo "hook-active" || echo "no-hook"

If hook-active: just commit normally — Caliber syncs automatically via the hook. Tell the user: "Caliber will sync your agent configs automatically." If no-hook: run caliber refresh && git add CLAUDE.md .claude/ .cursor/ .cursorrules .github/copilot-instructions.md .github/instructions/ AGENTS.md CALIBER_LEARNINGS.md 2>/dev/null before committing, and tell the user what was updated.

If caliber is not found, read the setup-caliber skill from .cursor/skills/setup-caliber/SKILL.md and follow its instructions to install Caliber.

Changes

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.
