A GitHub investigator for open issues and pull requests. It sorts them, examines the codebase for likely causes or changes, and reports findings with file and line references.

Use it to investigate individual or batches of issues, review pull requests, find stale issues, and optionally implement proposed fixes.

It turns a large or unclear queue of GitHub work into classified investigations with concrete code references.

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.

agentmods

npx agentmods add skills/sethgammon/citadel/triage

Any agent

npx skills add SethGammon/Citadel --skill triage

Clone the repo

git clone --depth 1 https://github.com/SethGammon/Citadel

Made for: Claude Code, Codex.

Or install citadel, the plugin that ships this one along with the rest of its 49 skills, 7 agents, 2 MCP servers.

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	$0.00071	$0.02796
Opus 5	$0.00036	$0.01398
Sonnet 5	$0.00014	$0.00559
Haiku 4.5	$0.00007	$0.00280

Security

Grade A, and why

triage 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.

How it starts

The opening of the file, as written. The whole thing — 300 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Triage — GitHub Issue & PR Investigator

When to Use

Don't use when: fixing a specific already-diagnosed issue (use /marshal); monitoring a single PR's CI (use /pr-watch); reviewing code quality outside of GitHub issues (use /review).

/triage — triage all open, unlabeled issues
/triage 10 — investigate issue #10 specifically
/triage pr 13 — review PR #13
/triage prs — review all open PRs
/triage --batch — pull all open issues, classify, investigate, report
/triage --stale — find issues older than 14 days with no activity
After the issue-monitor SessionStart hook reports new issues

Codex PR review integration

For Codex-visible PRs, decide whether to use native @codex review, local Citadel triage, or both:

node scripts/codex-pr-review.js plan --repo <owner/repo> --pr <number> --risk <low|medium|high|local-only> --write

Use native @codex review when the diff is GitHub-visible and the main need is a focused P0/P1 review. Use local Citadel triage when the answer depends on unpushed files, local generated artifacts, or hands-on edits. Use both for large or risky PRs.

After Codex posts a GitHub review, fetch and ingest the review comments before deciding merge readiness:

node scripts/codex-review-fetch.js --repo <owner/repo> --pr <number> --write

Use --file <review-comments.json> with the same script when working from exported/offline review data.

Treat ingested P0/P1 findings as blockers until local verification confirms they are fixed or not applicable.

Inputs

Input	Source	Required
Issue/PR number	Argument (e.g., `/triage 10`, `/triage pr 13`)	No — omit to triage all open
Mode	`pr` prefix for PRs	No — defaults to issues
Repo	Auto-detected from git remote	Yes (auto)
gh CLI	`"/c/Program Files/GitHub CLI/gh.exe"` on Windows, `gh` elsewhere	Yes (auto)

Execution Protocol

Phase 0 — Environment Setup

Detect repo from git remote get-url origin, extract owner/repo
Verify gh auth status
Set $GH: Windows → "/c/Program Files/GitHub CLI/gh.exe", other → gh

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

triage is a skill published in the GitHub repository SethGammon/Citadel (916 stars, last pushed yesterday), licensed MIT. It adds 71 tokens to every session and 2,796 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 2026-08-30.
