What is gh-fine-grained-pat?

A browser-automation tool that creates, checks, lists, and revokes narrowly scoped GitHub personal access tokens. A personal access token is a password-like credential that programs use to access GitHub.

Use it to make tokens for release tools, continuous-integration status reporting, read-only auditing, or account-specific access, and to rotate or revoke them.

GitHub does not provide an API for creating these fine-grained tokens, so repeated manual setup is difficult to reproduce and review. A declarative specification records the requested permissions and settings.

NVIDIA SkillSpector warn 7 Sept 2026

SkillSpector: 4 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

high Privilege Escalation · line 3
Code accesses credential files (SSH keys, AWS credentials, etc.). This could indicate credential theft attempts.

Fix: Remove references to credential paths. Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.
medium Rogue Agent · line 3
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.
medium Prompt Injection · line 69
Large whitespace padding was detected (a block of blank lines or a long run of spaces). This can push injected instructions below or to the right of the visible area so a human reviewer never sees them while the agent still reads them. Manual review of the hidden content is recommended.

Fix: Remove the large whitespace padding (blank-line blocks or long space runs) and review any content hidden below or to the right of it. Keep skill files compact and reviewable so no instructions can be
medium Privilege Escalation · line 95
Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.

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	$0.00096	$0.01932
Opus 5	$0.00048	$0.00966
Sonnet 5	$0.00019	$0.00386
Haiku 4.5	$0.00010	$0.00193

Security

Grade B, and why

gh-fine-grained-pat scanned grade B with 1 finding 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 6d ago.

The scan reads SKILL.md. This mod also ships 11 executable files (scripts/autosudo.mjs, scripts/browser.mjs, scripts/form.mjs, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

GitHub's **sudo mode** ("Confirm access") normally needs a human gesture. The engine can clear it autonomously using a self-custodied credential — see the [ADR](/docs/adr/2026-06-26-autonomous-github-web-auth-virtual-pas

gh-fine-grained-pat — declarative fine-grained PAT forge

GitHub exposes no API to create fine-grained PATs (community #148626) — the web UI is the only way. This skill drives that UI over the Chrome DevTools Protocol from a declarative JSON spec, so token creation is repeatable, reviewable, and anti-fragile instead of a hand-clicked one-off.

Self-Evolving Skill: This skill improves through use. GitHub's settings UI drifts — if a selector misses, the modal/picker/permission flow changed, or a permission's detail-page noun is wrong, fix scripts/, CLAUDE.md (selector map + noun map), or the spec immediately; don't defer. Only update for real, reproducible breakage.

When to use

Mint a scoped token (release bot, CI reporter, read-only auditor, account-scoped) for storage in the SCS vault.
Re-create / rotate a token from a checked-in spec.
List, verify (read back settings), or revoke fine-grained tokens.

Prerequisites

node (NOT bun — Bun's connectOverCDP times out) and playwright-core (already pinned at the repo root package.json).
Google Chrome at the standard macOS path.
A one-time GitHub login (persisted in a profile; see below).

A persistent Chrome profile holds the GitHub session cookie, so you log in once and every later run reuses it:

cd plugins/gh-tools/skills/gh-fine-grained-pat
node scripts/pat.mjs login      # opens Chrome; sign in (incl. 2FA); it auto-detects success
node scripts/pat.mjs doctor     # runtime + chrome + profile + auth health

The profile lives at ~/.local/share/gh-pat-automation/profile (override with GH_PAT_PROFILE_DIR). Treat it as sensitive — it can impersonate your GitHub session. It is outside the repo and never committed.

Create a token from a spec

# write the value to a 0600 file (default) — the value is NEVER printed to the terminal
node scripts/pat.mjs create specs/release-bot.json --out /tmp/.tok

# …or pipe it straight into the SCS vault (value passed in-process, never to chat)
node scripts/pat.mjs create specs/release-bot.json --vault cc-skills:gh.token

# rotate: revoke the same-named token, create a replacement, store it (sink required)
node scripts/pat.mjs rotate specs/release-bot.json --vault cc-skills:gh.token

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.

gh-fine-grained-pat is a skill published in the GitHub repository terrylica/cc-skills (72 stars, last pushed yesterday), licensed MIT. It adds 96 tokens to every session and 1,932 once invoked, about $0.0005 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
