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

ape-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 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.

What it actually says

Commit Message Style

Format

<short summary line>

- <change>
- <change>
- <change>

Rules

Summary line (first line)

  • One line only
  • Short and crisp -- aim for under 72 characters
  • Use the imperative mood: "Add feature" not "Added feature" or "Adds feature"
  • No trailing period
  • Describe what the commit does, not how

Blank lines

  • Always exactly one blank line between the summary line and the bullet list (never omit it)
  • No blank lines between bullet list items -- the list must be tight and contiguous (single newline after each item, never an empty/blank line)
  • No trailing blank lines at the end of the commit message

Bullet points

  • Each bullet describes a single, specific change
  • Short and crisp -- one line per bullet
  • Keep bullet items contiguous with no blank lines between them
  • Start each bullet with a verb in the imperative mood (Add, Fix, Remove, Update, Rename, Move, Extract, etc.)
  • No trailing periods
  • No fluff or filler words

Never include

  • Blank lines between bullet list items (loose lists)
  • Co-author lines (no Co-authored-by: trailer)
  • Generated by Claude or any AI attribution
  • Redundant context already obvious from the diff

Examples

Good:

Add user authentication middleware

- Add JWT validation to protected routes
- Return 401 on missing or expired token
- Extract auth logic into separate middleware file
- Add unit tests for token validation
Fix null pointer crash on empty cart checkout

- Guard against null items array before totalling
- Add early return when cart has no items
- Log warning when checkout attempted on empty cart

Bad (do not do this):

Updated some stuff and fixed a few things that were broken and also added
some new features to the codebase

- I made some changes to the auth file because it was crashing

- Also fixed the cart thing

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.
