What it does

Phoenix Framework is an agent skill from podlove/radiator. Use this skill working with Phoenix Framework. Consult this when working with the web layer, controllers, views, liveviews etc.

Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/phoenix/ecto.md`, `references/phoenix/elixir.md` and `references/phoenix/html.md`).

It sits in AI & LLM Engineering, covering LLM observability. It works with Elixir. The repository describes itself as: Podcast Hosting & Publishing | The spark ✨ that lights the fire 🔥. The licence is MIT.

When your agent uses it

  • Tasks that involve LLM observability

Example prompts

  • “/phoenix-framework”

What it can do on your machine

Read from SKILL.md and the folder at commit 1da64dd. 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

    No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).

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

  • Network

    No URLs in SKILL.md.

    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

Phoenix Framework loads about 562 tokens when it runs, and up to ~5.4k if it reads all its reference files. Until then it costs about 36 tokens; SKILL.md has 185 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~36
When it runs · the whole SKILL.md, loaded when a task matches
~562
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.4k

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.
