build-tdds SKILL.md skillA
build-tdds from cahenesy/throughline is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add cahenesy/throughline/build-tdds@git:20261012.e4434fcPins git:20261012.e4434fc in mdr.lock. Pin the fingerprint instead.

Turn features described in the PRD and designed in TDDs into code and tests. Confirms the queue, then sequences one implementer worker, mechanical gates, one runtime-verify worker, and one reviewer worker. Opens a PR per TDD. Never merges. Invoke with /build-tdds.
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
# `/build-tdds`
Interactive parent skill. It sequences workers; it is not a detached
coprocess. Session survival is whatever the harness does.
Usage: `/build-tdds [<tdd-path>] [--combined | --parallel] [--escalate]
[--no-auto-escalate]`. `--escalate` (or `THROUGHLINE_ESCALATE=1`) runs
this run's judgment workers on the escalation model; `--no-auto-escalate`
(or `THROUGHLINE_AUTO_ESCALATE=0`) declines the automatic escalation of a
Retry (FR-88).
## Block contract (every `<!-- tl:… -->` block)
The harness runs each shell call in a fresh shell, so a marker-tagged
block never relies on a variable or function from an earlier call. Run
each block as one shell command. Each block:
- sources its own helpers, fail closed: plugin-root, `models.sh`, and
`run-record.sh` (except `tl:fr86-check`, whose bytes are shared with
`/prd-author` and `/tdd-author`);
- computes `TL_PARENT="$(tl_parent_model 2>/dev/null)" || TL_PARENT=""`
itself when it needs the parent model;
- reads inputs only from env vars, as `${VAR:?VAR required}`, so a
missing input fails loudly. Prefix the block with `export` lines that
carry the real values, e.g.

How to install
mdr add cahenesy/throughline/build-tdds@sha256:2bb26833d7e7d836The line at the top of this page pins the label git:20261012.e4434fc, 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.
