Reference document describing six pre-flight checks (clean git state, not detached HEAD, gh auth, issue exists and OPEN, remote reachable, duplicate-branch warning) as pure bash exit codes with no LLM calls. Reference only (policy document; consumed by `/flow:start` Phase 0).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Pre-flight Checks ## Contract Iron law: no LLM calls in pre-flight — every check is a bash command with a pass/fail exit code, and a failed pre-flight stops the workflow before any token is spent on planning. Consumed by `/flow:start` Phase 0 (PRE-FLIGHT); the runnable bash lives in `plugins/flow/commands/start.md` and is never invoked as `Skill(preflight-checks)`. That bash returns a `### Pre-Flight` section with `ISSUE_NUM=`, `PREFLIGHT_ERRORS=`, `PREFLIGHT_WARNINGS=`, `PREFLIGHT_STATE=PASSED|BLOCKED`, then one `PREFLIGHT_FAIL=<reason>` line per error and one `PREFLIGHT_WARN=<reason>` per warning. `PREFLIGHT_STATE=BLOCKED` halts before EXPLORE. Permitted skips: none — warnings surface and proceed; errors always halt. ## What Pre-flight Protects Pre-flight is the cheapest filter: it runs before EXPLORE, before any agent dispatch, before any reasoning, and fails fast on conditions that would invalidate everything downstream. Because it is honest about what it proves, downstream phases trust their preconditions and stop re-checking them. ## The Checks | # | Check | Failure mode it prevents | |---|-------|--------------------------| …

How to install
mdr add synaptiai/synapti-marketplace/preflight-checks@sha256:7d52ba60f0a04ac1The line at the top of this page pins the label git:20260909.6778255, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
