ralph-two-pass-scan

ralph-two-pass-scan is a skill for Claude Code, Codex from github/gh-aw. It costs 20 tokens per session (345 once invoked), scanned A, original, MIT.

A two-step GitHub issue-scanning process: first list lightweight issue details, then load full details only for issues that need review.

In plain words
What is it for?
Scanning open GitHub Issues, filtering the list, selectively loading issue bodies and comments, and applying triage rules.
Why use it?
It avoids making a separate full API request for every issue. Filters remove already-owned, blocked, completed, postponed, or low-signal issues before detailed triage.

About the project

GitHub Agentic Workflows is a GitHub CLI extension that lets developers define AI-assisted repository automation in Markdown and run it through GitHub Actions. It is intended for tasks requiring interpretation or reasoning, such as issue triage, pull-request review, CI investigation, documentation maintenance, and dependency analysis. The catalogue entries provide skills and agents for working with these workflows.

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

ralph-two-pass-scan 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 2d 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

Skill: Ralph — Two-Pass Issue Scanning

Confidence: high Domain: work-monitoring Last validated: 2026-03-24

Context

Cuts GitHub API calls from N+1 to ~7 per round (~72% reduction) by separating list scanning from full hydration. Addresses the scanning inefficiency described in issue #596.

Pattern

Pass 1 — Lightweight Scan

gh issue list --state open --json number,title,labels,assignees --limit 100

Skip hydration if ANY of these match:

Condition Skip reason
assignees non-empty AND no status:needs-review Already owned
Labels contain status:blocked or status:waiting-external Externally gated
Labels contain status:done or status:postponed Closed loop
Title matches stale/noisy pattern ([chore], [auto]) Low-signal

Pass 2 — Selective Hydration

For each issue surviving Pass 1:

gh issue view <number> --json number,title,body,labels,assignees,comments,state

Then apply normal Ralph triage logic. Rule of thumb: hydrate ≤ 30% of scanned list. If more than 30% survive Pass 1, tighten filter rules.

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.
