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 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 1mo 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.

Origin

This is a copy

91% identical to commit — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 170 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sentry Commit Messages

Follow these conventions when creating commits for Sentry projects.

When to Use This Skill

Use this skill when:

  • Committing code changes
  • Writing commit messages
  • Formatting git history
  • Following Sentry commit conventions
  • Referencing Sentry issues in commits

Prerequisites

Before committing, ensure you're working on a feature branch, not the main branch.

# Check current branch
git branch --show-current

If you're on main or master, create a new branch first:

# Create and switch to a new branch
git checkout -b <type>/<short-description>

Branch naming should follow the pattern: <type>/<short-description> where type matches the commit type (e.g., feat/add-user-auth, fix/null-pointer-error, ref/extract-validation).

Format

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

<body>

<footer>

The header is required. Scope is optional. All lines must stay under 100 characters.

Commit Types

Type Purpose
feat New feature
fix Bug fix
ref Refactoring (no behavior change)
perf Performance improvement
docs Documentation only
test Test additions or corrections
build Build system or dependencies
ci CI configuration
chore Maintenance tasks
style Code formatting (no logic change)
meta Repository metadata
license License changes

Subject Line Rules

  • Use imperative, present tense: "Add feature" not "Added feature"
  • Capitalize the first letter
  • No period at the end
  • Maximum 70 characters

Body Guidelines

  • Explain what and why, not how
  • Use imperative mood and present tense
  • Include motivation for the change
  • Contrast with previous behavior when relevant

Reference issues in the footer using these patterns:

Fixes GH-1234
Fixes #1234
Fixes SENTRY-1234
Refs LINEAR-ABC-123
  • Fixes closes the issue when merged
  • Refs links without closing

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.
