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.

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 | $0.00225 | $0.00225 |
| Opus 5 | $0.00112 | $0.00112 |
| Sonnet 5 | $0.00045 | $0.00045 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
pr-creation 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
Pull request creation
When opening or editing a GitHub PR, read and follow the create-pull-request skill
(.agents/skills/create-pull-request/SKILL.md).
Quick rules
- Title:
type(scope): plain English— no feature ledger IDs, audit codes, or contract paths. - Body: full template in the skill — Summary, Problem, Solution, Behaviour changes, Files changed, Risk and rollout, Test plan. Enough detail for a reviewer who was not in the session.
- Keep local: contracts,
FEATURES.jsonIDs, harness-review output,PENDING_REVIEW— chat only. - Never: tool attribution (
Made with Cursor,Co-Authored-Byassistant) in title, body, or commits.
Harness review runs before the PR; its output goes to the human in chat, not on GitHub.
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.

pr-creation is a cursor rule published in the GitHub repository David405/harness-kit (2 stars, last pushed 3d ago), licensed Apache-2.0. It adds 225 tokens to every session, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
