In plain words

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

goal-flight-doctor 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.

What it actually says

goal-flight-doctor

Use this skill when the user asks for /goal-flight doctor, goal-flight readiness, setup verification, or host/worker diagnostics.

Steps

  1. Read the repository AGENTS.md first when present.
  2. Read the repository root SKILL.md as the canonical Goal Flight workflow.
  3. Read commands/doctor.md.
  4. Run the procedural doctor for the current repository:
python3 scripts/goalflight_doctor.py --project-root "$PWD"

Keep long probe details out of chat. Return the checklist summary and the highest-priority blocker, if any.

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.
