What it does

Warden Service is an agent skill from getsentry/warden, published by the product's own GitHub organization. Queries and summarizes the Warden Service read API. Use when asked to inspect, search, summarize, or export Warden runs, findings, costs, outcomes, repositories, skills, or memories through Warden Service.

Its SKILL.md is about 940 tokens, which your agent loads only when the skill is triggered. The skill folder holds 11 other files, including reference files (for example `evals/cases/diagnose-api-errors.yaml`, `evals/cases/establish-safe-api-access.yaml` and `evals/cases/follow-bounded-pagination.yaml`).

The repository describes itself as: Your code is under new management. Agents that review your code.

When your agent uses it

  • Asked to inspect
  • Export Warden runs
  • Memories through Warden Service

Example prompts

  • “Use the warden-service skill to query and summarizes the Warden Service read API. An agent skill from getsentry/warden”
  • “/warden-service”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Identify the Warden Service origin and confirm WARDEN_PAT is set without displaying its value.
  2. If the token is missing, direct the user to API access in the Warden Service dashboard. Have them create a personal token and export it as…
  3. Read references/read-api.md to select the exact route, supported filters, pagination behavior, and response fields for the question.
  4. Narrow the request to the user's repository, time range, skill, severity, or other stated scope. Use a bounded limit for runs and findings.
  5. Send a GET request with the token read from the environment. URL-encode every query value.
  6. Follow nextCursor only while more results are needed. Preserve all original filters and stop when the requested scope is satisfied or the…
  7. Summarize the relevant JSON fields. State the route and filters used, and distinguish an empty result from a failed request.

What it can do on your machine

Read from SKILL.md and the folder at commit 1ee135e. 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:

    • curl

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use curl, 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 Service loads about 944 tokens when it runs, and up to ~2k if it reads all its reference files. Until then it costs about 55 tokens; SKILL.md has 423 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~55
When it runs · the whole SKILL.md, loaded when a task matches
~944
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2k

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.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 423 words (~944 tokens).

“Query Warden Service with a read-only personal token and return a bounded, evidence-based answer.”
