Build spex tasks — one task here, or, given only the spec folder, every ready task through fresh developer subagents, wave by wave, with spex done (the task's own tests green) as the only completion. A wrong test is judged by a decider and rewritten by a test-developer subagent, never by the developer or the user. Use when the user says "develop T01", "spex develop", "implement", "build everything", or when a NEXT block names /spex:develop.
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
# spex develop
`SPEX` = `node ${CLAUDE_PLUGIN_ROOT}/scripts/spex.mjs`, from the repo root.
Arguments: `<dir> <task>` builds one task here. `<dir>` alone orchestrates every ready task
through subagents until none is ready.
## One task, here
1. A `blocked` task: a person read its reason and named it, so `SPEX unblock <dir> <task>`
first. A block with `--ask`: this run is the yes. Then `SPEX gate develop <dir> <task>`:
the task's tests exist, its `needs` are met, and the tests fail (it runs them).
Refused: report `STATUS: blocked` with the findings and stop. Never work around a gate.
2. `SPEX show <dir> <task>` is your spec: the task, its tests (the proof), its records, the
boundaries, the decisions, the design slice. Read the files under `context`, and only
those. Pull more by id (`SPEX show <dir> REQ-…`, `--design`, `--decisions`), named in
the report.
3. Write only inside `paths`. Never a `protected` path, never a test folder, never
`tests.yaml`. A test that asserts other than its claim: do not fix it or code around it;
do **A wrong test** below, then step 7.
4. Red first: the tests fail before the code. Write the smallest code that makes them pass,
…Read the whole file at its exact version.
How to install
mdr add lukaskellerstein/claude-my-marketplace/develop@sha256:d0e62bbc44afe4dcThe line at the top of this page pins the label git:20261107.629412d, 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.
