Running ci:preflight
SkillProductivityCatch the deterministic CI failures reachable from your diff before pushing, with `hogli ci:preflight`. Use when the pre-push hook blocks a push, before reporting a task done, or after editing Python, serializers, migrations, workflows, or dependency manifests — to avoid burning a CI matrix on a failure you could catch locally (formatting, lint, broken lockfiles, OpenAPI drift, migration conflict, stale branch). Trigger terms: ci:preflight, preflight, pre-push checks, pre-push hook failed, "will this break CI".

hogli ci:preflight scopes a curated set of checks to the files your branch touched — each mapped to a
CI failure class that has taken master down — plus an always-on branch-freshness check. It is the
pre-push counterpart to hogli ci:insights (what is already broken on master).
The pre-push hook runs ci:preflight --strict automatically and blocks the push on failed checks.
Never bypass it with --no-verify — fix what it reports instead.
The loop (when the hook blocks, or before reporting done)
hogli ci:preflight --fix
- Run with
--fix— it formats, lints, and auto-fixes what is safe. - Read each line:
✓ pass,✗ fail,⚠ warning(non-blocking finding),→ advisory(do it yourself),· skipped(capability absent). - Resolve every
✗ fail— these are what--fixcould not (real lint error, broken lockfile, migration conflict). These block the push. - Act on every
→ advisory— e.g.openapiadvisory → runhogli build:openapiand commit the drift;stalenessadvisory →git merge origin/master. Advisories never block, but ignoring them ships the failure to CI. Resolve them before pushing, including drift you didn't introduce — you own the branch state you push. - Re-run until clean, then push.
Notes
- Strict = failures only.
--strict(what the hook runs) exits non-zero only on✗ fail— advisories are unverifiable-locally classes, so they warn without blocking. A clean exit means "nothing left to fix", not "CI will pass" — CI stays the authoritative gate. Non-blocking is a mechanism limit, not permission to skip. type-checkis a nudge, not a run. Only a repo-wide mypy run matches CI (mypy follows imports, so a changed-file subset misses reverse-dependency breakage), and that costs minutes cold — too much to tax every push with. So preflight names the command instead of running it: judge whether your change is type-risky and run it yourself. CI blocks on the same command, so a type error you skip here comes back as a full re-run.complexitywarns only. Cyclomatic complexity above 10 in a changed file shows as⚠ warningand never blocks; CI annotates the same warning and posts it to the CI report comment. Simplify the function when you next touch it rather than gaming the number.- Staleness is risk-based. It fires when merging master now would actually break something — textual merge conflicts (computed via
git merge-tree, working tree untouched), migrations added on both sides, generated-file inputs changed on both sides, or CI workflows changed on master — plus a behind/age backstop, aggressive by default (5 commits / 2 days; env-tunable viaHOGLI_PREFLIGHT_STALE_COMMITS/HOGLI_PREFLIGHT_STALE_DAYS) so we over-warn to start and tune down from telemetry. Merge master in when it fires. Advisory only, never auto-merged. · skipped (needs …)is expected on a bare checkout or sandbox.needs stack/needs clickhousewant a running dev stack (hogli start),needs nodewantspnpm install,needs desktop-nodewantspnpm --dir products/desktop install(the nested desktop workspace is excluded from the root install and has its own lockfile), andneeds python-envwantsuv sync, so the synced project environment is thepythonon PATH. Satisfy what you can, or let CI cover the rest. No hooks in your environment (nonode_modules)? Run the loop yourself before pushing.- Flags.

HOGLI_PREFLIGHT_DISABLED=1makes the command (and the hook) a no-op with exit 0. It is a rollout/emergency lever — respect it; never unset it to force a run.
Why it matters
Drafts already run a trimmed CI subset; the expensive waste is a ready PR that fails the full matrix on something deterministic, gets fixed, and re-runs the whole matrix. Catching that locally is the cheapest CI saving available.
