What it does

Council is an agent skill from simstudioai/sim. Spawn parallel task agents to explore a given area of the codebase from multiple angles, then use their findings to answer the question or build a plan. Use when a task needs broad fan-out exploration across many files before acting.

Its SKILL.md is about 260 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

The repository describes itself as: Sim is the collaborative workspace to build, deploy, and monitor AI agents and workflows. Used by 100,000+ builders. The licence is Apache-2.0.

When your agent uses it

  • A task needs broad fan-out exploration across many files before acting

Example prompts

  • “/council”

Workflow steps

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

  1. Dig around the codebase in terms of that given area of interest, gather general information such as keywords and architecture overview.
  2. Spawn off n=10 (unless specified otherwise) task agents to dig deeper into the codebase in terms of that given area of interest, some of…
  3. Once the task agents are done, use the information to do what the user wants.

What it can do on your machine

Read from SKILL.md and the folder at commit 546d4e7. 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

Council loads about 256 tokens when it runs. Until then it costs about 60 tokens; SKILL.md has 93 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~256

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.

argument-hint
<area-of-interest>

Based on the given area of interest, please:

  1. Dig around the codebase in terms of that given area of interest, gather general information such as keywords and architecture overview.
  2. Spawn off n=10 (unless specified otherwise) task agents to dig deeper into the codebase in terms of that given area of interest, some of them should be out of the box for variance.
  3. Once the task agents are done, use the information to do what the user wants.

If user is in plan mode, use the information to create the plan.
