preflight

preflight is a command for coding agents from AURORA-NEURO/aurora-agent. It costs 20 tokens per session (296 once invoked), scanned A, original, Apache-2.0.

A preflight check for an aurora-agent mission, meaning a review performed before the mission runs. It validates the request, builds an execution plan, and shows approval-gate status without dispatching work.

In plain words
What is it for?
Use it to inspect the plan digest, execution waves, evidence decision, required approvals, group gates, prerequisites, and readiness status.
Why use it?
It exposes missing requirements and human-review needs before anything is executed.

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

preflight 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 5d 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

Preflight a mission against the aurora-agent backend without executing it.

  1. If $ARGUMENTS names a JSON file, read it as the mission request. Otherwise use the demo mission from the mission-lifecycle skill (fiber_compile on the reference fixtures; remember every step needs domain and capability).
  2. Preferred transport: the agent_mission MCP tool is EXECUTION — do NOT use it here. Preflight goes through the HTTP gateway: POST /v1/missions/preflight on a running bioprism-api (launch line is in the aurora-agent docs/HTTP_API.md). If no gateway is running, say so and offer the launch command rather than executing anything.
  3. Report verbatim: dispatch (expect "not_started"), the plan digest, the wave decomposition, operations_evidence.decision, acceptance_required/present/valid, dispatch_prerequisite, each group's gate_state and missing gates, and readiness_claimed. A complete evidence set still requires human review — never present preflight success as authorization to dispatch.
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.
