At a glance

Run the Kiln pre-release smoke test suite plus the standard CI checks (checks.sh), diagnose every prerelease test that broke (and why), and write a clean readable report with recommended actions.

  • Works in 6 steps: Set up the output directory → Run checks.sh → Run the prerelease pytest set → …
  • The user wants to validate a release candidate
  • SKILL.md covers What "prerelease" means here, Global rules, Phase 1 — Set up the output… and Phase 2 — Run checks.sh, plus 6 more sections
  • Calls uv, claude and gcloud; needs OPENAI_API_KEY and ANTHROPIC_API_KEY

What it does

Kiln Prerelease Check is an agent skill from Kiln-AI/Kiln. Run the Kiln pre-release smoke test suite plus the standard CI checks (checks.sh), diagnose every prerelease test that broke (and why), and write a clean readable report with recommended actions. Read-only — it never edits code. Use when the user wants to validate a release candidate, run prerelease tests, or asks for a "prerelease check / smoke / audit".

Its SKILL.md is about 7.8k 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 Testing & QA, covering QA and bug reports. It works with pytest and OpenAI. The repository describes itself as: Build, Evaluate, and Optimize AI Systems. Includes evals, RAG, agents, fine-tuning, synthetic data generation, dataset management, MCP, and more.

When your agent uses it

  • The user wants to validate a release candidate
  • Run prerelease tests
  • Asks for a prerelease check / smoke / audit

Example prompts

  • “prerelease check / smoke / audit”
  • “/kiln-prerelease-check”

Requirements

  • Python 3
  • A credential in OPENAI_API_KEY
  • A credential in ANTHROPIC_API_KEY

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Set up the output directory
  2. Run checks.sh
  3. Run the prerelease pytest set
  4. Diagnose
  5. Write the report
  6. Hand back to the user

What it can do on your machine

Read from SKILL.md and the folder at commit 8ac9075. 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:

    • uv
    • claude
    • gcloud

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

  • Network

    No URLs in SKILL.md. Its commands use uv and gcloud, 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 these keys or tokens, usually read from environment variables:

    • OPENAI_API_KEY
    • ANTHROPIC_API_KEY
    • GEMINI_API_KEY
    • GROQ_API_KEY
    • OPENROUTER_API_KEY
    • FIREWORKS_API_KEY
    • TOGETHERAI_API_KEY
    • SILICONFLOW_CN_API_KEY
    • COHERE_API_KEY
    • TYPESAFE_API_KEY
    • CLOUDFLARE_API_KEY
    • AWS_ACCESS_KEY_ID

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Kiln Prerelease Check loads about 7.8k tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 2,734 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~7.8k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:58
    - **Env vars:** Source `.env` before running anything that needs API keys. Use a real sourcing pass (not `export $(... |
  • NoteMentions a .env fileSKILL.md:60
    set -a; . ./.env; set +a

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 2,734 words (~7,766 tokens).
