What is hop CLAUDE.md?

A set of rules for writing Git commit messages in the conventional format, such as feat, fix, docs, or test followed by a short imperative description.

Writing commit messages for new features, bug fixes, documentation, refactoring, tests, chores, and continuous-integration changes.

It gives commits a consistent structure that makes project history easier to scan and automate.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00101	$0.00101
Opus 5.5	$0.00040	$0.00040
Sonnet 5.5	$0.00020	$0.00020
Haiku 4.5	$0.00010	$0.00010

Security

Grade A, and why

hop 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 2mo 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.

Commit Messages

Use conventional commit format with imperative mood:

Types: feat, fix, docs, refactor, chore, test, ci

fix: improve connection form UX
docs: sync documentation with recent feature additions
refactor: remove connection details panel from dashboard
chore: remove outdated specs directory

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.
