What it does

Brief is an agent skill from greenfield-inc/Pane. Use when a problem, idea, or change of intent is worth capturing as a long-form page, or the person asks to write it up. Never chooses a solution; the tracker issue belongs to create-ticket.

Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/brief-layout.md` and `references/saving.md`).

The repository describes itself as: Terminal-first, open-source AI agent manager for any CLI agent (agent agnostic), any OS (mac, windows, linux). The Open-Source Agentic Development Environment for running…

When your agent uses it

  • Change of intent is worth capturing as a long-form page
  • The person asks to write it up

Example prompts

  • “/brief”

What it can do on your machine

Read from SKILL.md and the folder at commit 0c471a3. 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.

    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

Brief loads about 821 tokens when it runs, and up to ~1.6k if it reads all its reference files. Until then it costs about 49 tokens; SKILL.md has 473 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~821
With references · SKILL.md plus every file in references/, read only if the agent opens them
~1.6k

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 473 words (~821 tokens).

“A brief says what is wrong or wanted, for whom, and how a user would know it is solved. It survives a change of approach, because it contains no approach. Alternatives belong in the options document. Steps belong in the…”
