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

commit-message-crafter 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 5d 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 Message Crafter

Write clear, consistent, and meaningful commit messages.

When to Use

  • Writing a commit message for staged changes
  • Following conventional commits format
  • Standardizing commit messages across a team
  • Writing messages for squash commits or PRs

The Conventional Commits Format

<type>(<scope>): <subject>

<body>

<footer>

Types

Type When to Use
feat New feature for the user
fix Bug fix for the user
docs Documentation only changes
style Formatting, missing semicolons, etc. (no code change)
refactor Code change that neither fixes a bug nor adds a feature
perf Performance improvement
test Adding or fixing tests
chore Maintenance tasks, dependencies, build changes
ci CI/CD configuration changes
revert Reverting a previous commit

Scope (Optional)

The part of the codebase affected:

  • auth, api, ui, db, config, deps, etc.

Subject Rules

  1. Use imperative mood: "Add feature" not "Added feature"
  2. Don't capitalize first letter
  3. No period at the end
  4. Max 50 characters (72 absolute max)
  5. Complete the sentence: "This commit will..."

Examples

Simple Feature

feat(auth): add password reset functionality

Bug Fix with Body

fix(api): handle null response from payment gateway

The payment gateway occasionally returns null instead of an error
object when the service is degraded. This caused uncaught exceptions
in the checkout flow.

Fixes #1234

Breaking Change

feat(api)!: change user endpoint response format

BREAKING CHANGE: The /api/users endpoint now returns paginated
results. Clients must update to handle the new response structure:
{ data: [], meta: { page, total } }

Refactoring

refactor(utils): extract date formatting into separate module

Moved date formatting logic from multiple components into a
centralized dateUtils module for better maintainability.

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.
