Individual skill

build

Plan-then-execute implementation against SPEC.md. Native single-thread loop, no sub-agents. On test or build failure, auto-invokes the backprop skill before retrying — a failed verification always considers whether a new §V invariant would prevent recurrence. Triggers when the user asks to build, implement, execute the spec, or tackle a specific §T task (`build §T.3`, `build --next`, `implement next task`, `run the build`). Expects SPEC.md to exist; if not, defers to the spec skill.

# build — implement spec

Single-thread native plan→execute. You are main Claude. No swarm.

## LOAD

1. Read `SPEC.md`. If missing → tell user to invoke the spec skill first. Stop.
2. Read `FORMAT.md` once if not loaded.
3. Read §R if present — external facts the build must honor, ⊥ re-derive or contradict.
4. Parse invocation args:
   - `§T.n` → that task only
   - `--next` → lowest-numbered row with status `.` or `~`
   - `--all` or empty → every `.` row in §T order
