Run the full Sailfin compiler validation pipeline (make clean-build then make check). Use before declaring a feature shipped, before cutting a release, or when you need to verify self-hosting still works after a structural change.
Systematically diagnose why a Sailfin source file or self-hosting build step fails to compile. Isolates the failure, identifies the pipeline stage, escalates to seed-stabilizer or compiler-architect when the fix is non-trivial, and verifies via test-runner. Use whenever `make compile` fails, a .sfn file won't build, or LLVM rejects generated IR.
Systematically diagnose Sailfin compilation, self-hosting, or LLVM lowering failures without adding build-driver workarounds.
Run Sailfin compiler and test verification safely with the required self-hosting and formatting gates.
Pick up a ready Sailfin Linear or GitHub issue and drive it through branch, implementation, verification, and PR handoff.
Plan Sailfin work in Linear from Initiatives through Projects to session-sized compiler/runtime issues. Use when Codex needs to audit or create Linear planning structure, prioritize production compiler/runtime health and performance, assign Projects/Cycles/priorities/estimates, groom Triage/Backlog/Ready/Blocked queues, or propose/apply bulk Linear issue updates.
Pin the Sailfin seed compiler to a specific released version. Updates bootstrap.toml [seed].version and the compiler [toolchain] floor, fetches the binary, and optionally runs a smoke compile to verify the new seed builds the compiler. Usage: /pin-seed <version> (e.g. /pin-seed v0.5.10-alpha.12 or /pin-seed 0.5.10-alpha.12).
Pin the Sailfin seed compiler to a published release and verify the seed binary.
