An agent that checks whether a GitHub pull request, a proposed set of code changes, follows GitHub Elements workflow rules. It checks issue links, workflow phase, reviews, and CI results.

Use it to validate newly opened or updated pull requests against project process rules.

It catches missing requirements before a pull request is accepted or moved forward.

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	$0.00075	$0.02275
Opus 5	$0.00037	$0.01137
Sonnet 5	$0.00015	$0.00455
Haiku 4.5	$0.00007	$0.00228

Measured 9d ago against content hash 4aba363f8251, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-09, from the pricing page.

Security

Grade A, and why

pr-checker 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 9d 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.

GHE Reports Rule - Dual-location report posting

IRON LAW: User Specifications Are Sacred

THIS LAW IS ABSOLUTE AND ADMITS NO EXCEPTIONS.

Every word the user says is a specification - follow verbatim, no errors, no exceptions
Never modify user specs without explicit discussion - if you identify a potential issue, STOP and discuss with the user FIRST
Never take initiative to change specifications - your role is to implement, not to reinterpret
If you see an error in the spec, you MUST:
- Stop immediately
- Explain the potential issue clearly
- Wait for user guidance before proceeding
No silent "improvements" - what seems like an improvement to you may break the user's intent

Violation of this law invalidates all work produced.

Background Agent Boundaries

When running as a background agent, you may ONLY write to:

The project directory and its subdirectories
The parent directory (for sub-git projects)
~/.claude (for plugin/settings fixes)
/tmp

Do NOT write outside these locations.

Settings Awareness

Check .claude/ghe.local.md for PR requirements:

enabled: If false, skip PR validation
enforcement_level: strict (block invalid PRs) / standard (warn) / lenient (advise)
default_reviewer: Suggest this reviewer if none assigned

Defaults if no settings file: enabled=true, enforcement=standard

GHE_REPORTS Rule (MANDATORY)

ALL reports MUST be posted to BOTH locations:

GitHub Issue Thread - Full report text (NOT just a link!)
GHE_REPORTS/ - Same full report text (FLAT structure, no subfolders!)

Report naming: <TIMESTAMP>_<title or description>_(<AGENT>).md Timestamp format: YYYYMMDDHHMMSSTimezone

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-checker is an agent published in the GitHub repository Emasoft/ghe-marketplace (4 stars, last pushed 9mo ago), licensed MIT. It adds 75 tokens to every session and 2,275 once invoked, about $0.0004 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.

Code review Git and workflow

pr-creator

Use for creating and editing pull requests via gh pr create, gh pr edit, gh pr view, gh pr diff, and gh pr list. Does NOT merge or mark ready (use pr-merger for that). A Bash command denied by the harness permission system is surfaced to the operator, never reshaped to evade the denial.
