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

register 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 6d 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.

Register Session

Register this session with a user-chosen name, role, and optional project tag.

Arguments (fast path)

If arguments are provided (e.g., name: planner | role: worker | project: myapp):

  1. Parse the provided name, role, and project from the arguments.
  2. Skip the pre-check gate and interactive prompts entirely.
  3. Call the register tool directly with the provided values.
  4. If the tool returns an error (e.g., name in use), report it clearly.
  5. If successful, confirm: "Registered as {name} with role {role}." If a project was set, add: "Broadcasts and DMs scoped to project {project}."
  6. Stop here — do not proceed to the pre-check or interactive registration.

Pre-check (gate)

Before prompting the user, determine if registration is needed:

  1. Read your session id from the MCP server instructions (the "Your session id is ..." line).
  2. Call the who tool to list active sessions.
  3. Find your session id in the results.
    • If your session's name is different from your session id (i.e. not session-XXXXXX), registration was already done AND no arguments were provided. Stop here silently — do not prompt the user.
    • If your session is not found or its name still equals the auto-generated id, proceed to registration.

Registration steps

  1. Ask the user: "What session name would you like to use?" (e.g., planner, backend, reviewer, tests)
  2. Wait for their response.
  3. Before proceeding, check the who results from the pre-check. If the requested name is already taken by another session, tell the user: "That name is already in use." Show the active session list and ask them to pick a different name. Repeat until available.
  4. Ask the user: "What role should this session have?" (e.g., orchestrator, worker, reviewer, specialist)
  5. Wait for their response.
  6. Ask the user: "What project tag should this session use? (optional — if set, broadcasts will be scoped to this project only)"
    • If there are active sessions with non-empty project tags, list the distinct project tags: "Active projects: myapp, api-server. You can pick one of these or enter a new one."
    • The user can leave this blank for no project (global broadcasts).
  7. Wait for their response.
  8. Call the register tool with the provided name, role, and project (if given).
  9. If the tool returns an error about the name being in use, it may be a stale session from a previous /resume or /clear. Tell the user: "That name is held by a stale session that will expire within 60 seconds. Wait and retry, or pick a different name." Show the active session list.
  10. Confirm success: "Registered as {name} with role {role}." If a project was set, add: "Broadcasts and DMs scoped to project {project}."

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.
