Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

octant-council-builder scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Read this file, then follow the steps below to set up the council plugin for the user.

Steps

  1. Detect the user's shell ($SHELL) and resolve the config file:

    • zsh → ~/.zshrc
    • bash → ~/.bashrc (or ~/.bash_profile on macOS if .bashrc doesn't exist)
    • fish → ~/.config/fish/config.fish
  2. Check if the council repo exists locally:

    • Look for .claude-plugin/plugin.json in the current directory
    • Check common locations: ~/git/octant-council-builder, ~/octant-council-builder, ~/projects/octant-council-builder, ~/code/octant-council-builder, ~/src/octant-council-builder
    • If found, store the absolute path as $PLUGIN_DIR
    • If not found, set $REPO_FOUND=false
  3. Before doing anything else, explain to the user what setup will do and ask for confirmation. Include:

    • How plugins work: --plugin-dir tells Claude Code to load .claude-plugin/plugin.json from a directory and register all skills/*/SKILL.md files as slash commands
    • If repo not found: that we'll clone it from https://github.com/golemfoundation/octant-council-builder.git
    • That we'll create a shell alias (e.g. alias council='claude --plugin-dir /path/to/repo')
    • Why the alias is useful: keeps things isolated — the council only loads when you use the alias, plain claude stays clean
    • That we'll enable the agent teams env var (CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1)
    • That the alias points at the local clone, so editing agent/skill markdown files takes effect immediately
    • Mention /reload-plugins for picking up skill changes during a live session
    • Wait for user confirmation before proceeding. If they cancel, stop.
  4. If repo was not found, ask where to clone it (default: ~/git/octant-council-builder) and run:

    git clone https://github.com/golemfoundation/octant-council-builder.git "$CLONE_DIR"
    

    Set $PLUGIN_DIR to the clone location.

  5. Ask the user what alias name they want (e.g. council, pgc, eval, betty, hal).

  6. Check the alias isn't already taken (command -v / alias). If it is, let them know and ask again.

  7. Remove any existing lines tagged # public-goods-council from the config file, then append:

    For zsh/bash:

    alias NAME='claude --plugin-dir PLUGIN_DIR'  # public-goods-council
    export CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS=1  # public-goods-council
    

    For fish:

    alias NAME "claude --plugin-dir PLUGIN_DIR"  # public-goods-council
    set -gx CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS 1  # public-goods-council
    
  8. Tell the user to run:

    source [config file] && cd $PLUGIN_DIR && $ALIAS_NAME
    

    Then explain:

    • How the alias works: --plugin-dir loads the plugin from the repo. The council skills only appear when you use the alias — plain claude stays unaffected.
    • Developing your council: agents are markdown files in agents/ — edit them and changes are picked up on the next /council:evaluate. Skills are in skills/*/SKILL.md — run /reload-plugins inside a session to pick up skill changes without restarting. No build step, no compilation.
    • Sharing your council: once you design your own council, push your fork and share the repo URL. Anyone can clone it and run /council:settings to install your council as a plugin.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
