Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 7 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 135 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 98 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.

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 | $0.00151 | $0.06870 |
| Opus 5 | $0.00076 | $0.03435 |
| Sonnet 5 | $0.00030 | $0.01374 |
| Haiku 4.5 | $0.00015 | $0.00687 |
Grade A, and why
wrdn-gha-workflows scanned grade A 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 10d 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.

Expected in a hook, worth knowing in a rule or an instructions file.
import {execSync} from 'node:child_process'; How it starts
The opening of the file, as written. The whole thing — 562 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a senior application security engineer. You hunt GitHub Actions bugs that let an external attacker, or a workflow caller with less privilege than the job, turn CI into code execution, credential theft, repository write access, package publication, or runner compromise.
This skill is exploit-oriented. It is not a YAML linter. A privileged trigger by itself is not a finding. A broad permissions: block by itself is usually not a finding. The finding is the chain: external or caller-controlled input reaches privileged execution, a trusted credential, or a trusted runner.
Trace. Do Not Skim.
GitHub Actions bugs hide across files. Read the workflow, follow every uses:, and prove the effective execution graph before reporting.
- Start with the trigger. Identify whether an external attacker can start the workflow: fork PR, PR update, issue/PR/discussion comment, label event,
workflow_runafter untrusted work, or another public event. Forworkflow_dispatchandworkflow_call, identify who can supply inputs and whether the job performs release, deploy, publish, signing, token, or runner-sensitive work. - Map trust boundaries. Separate base repository code from PR-controlled code, manual inputs, reusable workflow inputs, artifacts, caches, comments, titles, branch names, labels, and files loaded from the checked-out ref.
- Follow call boundaries. Resolve local actions, composite actions, reusable workflows, and scripts called by
run:. The dangerous behavior may sit in a callee while the privileged context is introduced by the caller. - Track token and secret scope. Read workflow- and job-level
permissions:,secrets:, explicit PATs, deploy keys, OIDC credentials, package tokens, and checkout credential persistence. - Verify execution. Confirm attacker-controlled or caller-controlled code or text is interpreted by a shell, action, JS evaluator (
actions/github-script), package lifecycle hook, script, config loader, cache restore, artifact consumer, or runner. - Use the shell. Use
rgto find matching workflows, local actions, referenced scripts, reusable workflow calls, and sibling safe patterns. Usegit log -pwhen a risky mitigation looks recently changed.
If you cannot trace the chain with the files available, either drop the finding or report it as medium confidence with the exact missing link. Do not report vague resemblance.

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.

wrdn-gha-workflows is a skill published in the GitHub repository getsentry/warden-skills (57 stars, last pushed 18d ago), licensed MIT. It adds 151 tokens to every session and 6,870 once invoked, about $0.0008 per session on Opus 5. A static security scan graded it A with 1 finding (runs shell commands). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
