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

plan 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 1mo 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

Plan

Plan the requested work without implementing it. Inspect relevant context with read-only Qubicl tools. Do not change implementation files, start deployments, publish, or commit as part of planning.

Return a concise Markdown plan in the conversation. If the user requests a saved plan, writing that plan is the only planned file change: prefer write_file for a new plan and edit_file for an existing one. Use a user-provided destination; otherwise use .agents/plans/ with a descriptive kebab-case filename. A request for read-only planning does not authorize creating a plan file.

Include only useful sections:

  • goal and success criteria;
  • current evidence and assumptions;
  • ordered implementation steps;
  • files or components likely to change;
  • validation and rollback;
  • risks, tradeoffs, and unresolved decisions.

Use exact local paths and commands when known. Clearly label anything inferred. End by summarizing the decisions required before implementation.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
