At a glance

Check Kiln's model list for deprecated or sunset models across all providers.

  • Works in 5 steps: Extract Current Model-Provider Pairs → Check Each Provider → Report Findings → …
  • The user wants to find deprecated models
  • SKILL.md covers Global Rules, Phase 1 – Extract Current…, Phase 2 – Check Each Provider and Phase 3 – Report Findings, plus 3 more sections
  • Runs Python scripts from its folder; calls python3, gcloud and jq; reaches remote-config.getkiln.ai and ai-cloudflare-com.pages.dev; needs CLOUDFLARE_API_KEY and OPENAI_API_KEY

What it does

Kiln Check Deprecation is an agent skill from Kiln-AI/Kiln. Check Kiln's model list for deprecated or sunset models across all providers. Use when the user wants to find deprecated models, check model availability, audit the model list for stale entries, or mentions model deprecation/sunset/end-of-life.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including scripts (for example `scripts/check_provider.py` and `scripts/extract_models.py`).

It sits in AI & LLM Engineering. It works with Python and Google Cloud. 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 find deprecated models
  • Check model availability
  • Audit the model list for stale entries
  • Mentions model deprecation/sunset/end-of-life

Example prompts

  • “/kiln-check-deprecation”

Requirements

  • Python 3
  • A credential in CLOUDFLARE_API_KEY
  • A credential in OPENAI_API_KEY

Workflow steps

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

  1. Extract Current Model-Provider Pairs
  2. Check Each Provider
  3. Report Findings
  4. Mark Deprecated
  5. Verify

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

    Ships 2 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3
    • gcloud
    • jq
    • aws
    • curl
    • uv

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • remote-config.getkiln.ai
    • ai-cloudflare-com.pages.dev
    • raw.githubusercontent.com

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • CLOUDFLARE_API_KEY
    • OPENAI_API_KEY
    • ANTHROPIC_API_KEY
    • GEMINI_API_KEY
    • FIREWORKS_API_KEY
    • TOGETHER_API_KEY
    • SILICONFLOW_CN_API_KEY
    • CEREBRAS_API_KEY
    • GROQ_API_KEY

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

Context cost

Kiln Check Deprecation loads about 2.5k tokens when it runs. Until then it costs about 67 tokens; SKILL.md has 1,019 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k

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:15
    - **Env vars:** Source `.env` before running check scripts: `export $(grep -v '^#' .env | xargs)`
  • NoteMentions a .env fileSKILL.md:51
    export $(grep -v '^#' .env | xargs)
  • NoteMentions a .env fileSKILL.md:58
    export $(grep -v '^#' .env | xargs)

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); the scripts in this folder 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 1,019 words (~2,517 tokens).

“Audit libs/core/kiln_ai/adapters/ml_model_list.py to find models that have been deprecated, removed, or are approaching end-of-life across all providers. All checks are free — they use model-listing endpoints, not inference.”
