GFM: Gest Format

Use to mechanically clean and statically check a changeset. gfm does not own runtime tests or documentation checks; route those to gte and gdo.

Workflow

1. Identify project and changed files.
2. Read the project command contract in AGENTS.md, especially any just target mappings and focused-argument guidance.
3. Run formatting, linting, typechecking, compile/static checks, and diff hygiene appropriate to the project.
4. Fix mechanical issues.
5. Re-run failing checks.
6. Report every command run and whether it passed.

Use the target repository's project-specific command contract. Prefer just targets when AGENTS.md maps them. For the reusable Just command-contract model, see references/just_command_contract.md. Common concepts include:

just fmt [path]
just lint [path]
just typecheck
just static
just build
git diff --check

If no command contract exists yet, inspect the project manifests and propose or route to gsu to establish one. Do not substitute smoke checks for gte.

If the project uses cx in its Justfile, run cx lint or the mapped just cx-lint target as a static declaration check. cx lint validates incremental build/pipeline lines; it is not a test runner and should not be used as a substitute for gte.

When a repository is GitButler-managed, use but status or but diff to identify branch-owned changes before running mechanical checks. Read-only git diff commands are acceptable, but do not use raw git write commands in GitButler mode.

Tag And Dependency Checks

For code-facing changes, gfm may include lightweight ast-grep syntax or pattern checks from references/tag_dependency_workflow.md when those checks are part of the mechanical contract.
