What it does

Warden Security Review is an agent skill from UsefulSoftwareCo/executor. Run Warden security scans in this repo using Sentry's warden-skills. Use when asked to audit security, scan with Warden, investigate authz/data-exfil/code-execution/GitHub Actions risks, or triage Warden findings.

Its SKILL.md is about 1.3k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Security, covering Security review and Authorization and RBAC. It works with GitHub Actions and Sentry. The repository describes itself as: The missing integration layer for AI agents. Let them call any OpenAPI / MCP / GraphQL / custom js functions in secure environment. The licence is MIT.

Example prompts

“/warden-security-review”

What it can do on your machine

Read from SKILL.md and the folder at commit 9ef04e9. It shows what the files ask for, not the result of running them.

Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
- npm
- rg
- claude
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use npm, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Warden Security Review loads about 1.3k tokens when it runs. Until then it costs about 59 tokens; SKILL.md has 289 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~59
When it runs · the whole SKILL.md, loaded when a task matches: ~1.3k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description: Run Warden security scans in this repo using Sentry's warden-skills. Use when asked to audit security, scan with Warden, investigate authz/data-exfil/code-execution/GitHub Actions risks, or triage Warden findings.

Warden security review runbook

Use Warden as a first-pass scanner, then manually verify every finding against the code. A clean Warden run means "no findings from that skill/pass", not "the codebase is secure."

Setup

Warden uses Claude Code auth locally. For Claude Max usage:

bash

claude login

Run Warden through npm so the package version does not need to be committed:

bash

npm exec --yes --package=@sentry/warden -- warden --help

The repo has a warden.toml that uses remote skills from getsentry/warden-skills.

Reference skills are mirrored under .reference/warden-skills when needed. .reference/ is gitignored.

Local Outputs

Write run artifacts under .warden-runs/. Do not commit .warden/ or .warden-runs/.

Use JSONL output for later triage:

bash

mkdir -p .warden-runs
npm exec --yes --package=@sentry/warden -- \
  warden <targets...> --skill <skill> --fail-on off --report-on low --min-confidence low \
  --parallel 2 --log -o .warden-runs/<name>.jsonl

Warden may not treat bare directories as recursive targets. Prefer explicit quoted globs or a target file list.

Recommended Scans

Authz on cloud/API surfaces:

bash

npm exec --yes --package=@sentry/warden -- \
  warden "apps/cloud/src/auth/**/*.ts" "apps/cloud/src/api/**/*.ts" \
  "apps/cloud/src/routes/**/*.tsx" "packages/core/api/src/**/*.ts" \
  --skill wrdn-authz --fail-on off --report-on low --min-confidence low \
  --parallel 2 --log -o .warden-runs/authz.jsonl

Code execution on sink-bearing runtime/plugin files:

bash

rg -l "\b(exec|spawn|execFile|fork|subprocess|Deno\.Command|new Function|eval\(|vm\.|QuickJS|quickjs|Worker\(|import\(|compile|instantiate|runIn|shell|command|child_process)\b" \
  apps/local/src/server apps/cli/src packages/core/execution/src packages/core/sdk/src packages/kernel packages/plugins \
  -g "*.ts" -g "*.tsx" -g "!*.test.ts" -g "!*.spec.ts" -g "!*.e2e.ts" -g "!**/dist/**" -g "!**/node_modules/**" \
  > .warden-runs/code-execution-targets.txt

npm exec --yes --package=@sentry/warden -- \
  warden $(tr '\n' ' ' < .warden-runs/code-execution-targets.txt) \
  --skill wrdn-code-execution --fail-on off --report-on low --min-confidence low \
  --parallel 2 --log -o .warden-runs/code-execution.jsonl

Data exfiltration on backend/API/storage/plugin SDK surfaces:

bash

find apps/cloud/src/api apps/cloud/src/auth apps/local/src/server \
  packages/core/api/src packages/core/storage-core/src packages/core/storage-file/src \
  packages/core/storage-postgres/src packages/core/storage-drizzle/src \

  packages/plugins/file-secrets/src packages/plugins/keychain/src \
  -type f \( -name "*.ts" -o -name "*.tsx" \) |
  rg -v '(\.test\.|\.spec\.|\.e2e\.|dist/|node_modules/|embedded-migrations\.gen\.ts|/react/)' \
  > .warden-runs/exfil-targets-focused.txt

npm exec --yes --package=@sentry/warden -- \
  warden $(tr '\n' ' ' < .warden-runs/exfil-targets-focused.txt) \
  --skill wrdn-data-exfil --fail-on off --report-on low --min-confidence low \
  --parallel 2 --log -o .warden-runs/data-exfil.jsonl

GitHub Actions workflow risks:

bash

find .github -type f \( -name "*.yml" -o -name "*.yaml" \) > .warden-runs/gha-targets.txt

npm exec --yes --package=@sentry/warden -- \
  warden $(tr '\n' ' ' < .warden-runs/gha-targets.txt) \
  --skill wrdn-gha-workflows --fail-on off --report-on low --min-confidence low \
  --parallel 2 --log -o .warden-runs/gha-workflows.jsonl

How to Triage

Deduplicate findings by root cause. Warden often reports the same bug at the low-level sink, wrapper, API handler, and plugin-tool entrypoint.

For each candidate:

Trace whether input is user-controlled.
Identify the exact sink.
Check whether auth, scope, host allowlists, private-IP blocks, redirects, and DNS rebinding defenses exist.
Determine what data returns to the caller: raw body, parsed fields, typed error message, timing/status oracle, or no observable data.
State confidence and deployment caveats.

Current Known Findings

As of the Warden pass on 2026-04-29:

Real: authenticated SSRF in plugin/source setup URL fetching for OpenAPI, Google Discovery, GraphQL, and MCP remote endpoints.
Real: mutable third-party GitHub Actions refs in publish/release workflows, especially oven-sh/setup-bun@v2 and changesets/action@v1.
Clean in that pass: authz scan on cloud auth/API/core API surfaces; code-execution scan on narrowed CLI/runtime/kernel/plugin sink files.

Do not claim the whole codebase is secure from those clean runs. They are scoped scanner results.
