build

build is a command for coding agents from nguyenvanphituoc/shapeup-sdlc-plugin. It costs 15 tokens per session (420 once invoked), scanned A, original, MIT.

A command that implements one development task from its specification, following its acceptance criteria and allowed code area.

In plain words
What is it for?
Use it to pick up a specific task, or the next ready task on the board, and implement it with a minimal code change.
Why use it?
It keeps changes small and focused, while verifying the visible result instead of building an entire feature at once.

Command

Installs and runs on its own, but its text points at files inside its plugin — anything it tells you to read at a ${CLAUDE_PLUGIN_ROOT} path is only there once the plugin is installed. Installing the plugin gets both.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

build scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Use the task-executor skill on $ARGUMENTS.

Standalone build: implements one task (TASK-NNN) from a spec folder — assumption scan first, minimum code, surgical diffs, verified observable outcomes. Inside an orchestrated run the tech-lead dispatches this skill through the envelope port instead; this command is for picking up a single task directly.

If no task ID was given, read the board (.shapeup/<slug>/tasks/_index.md) and take the next ready task, stating which one you picked. Respect the substrate: if scope contracts exist, writes outside the active scope's whitelist will be denied by the sandbox hook — that is the harness working, not an error to route around.

Building a whole scoped feature is not this command

This command builds one task. A full BUILD round — every scope, the per-scope attempt loop, T0 verification, the inner circuit breaker, then the single EVAL — is a workflow-script launch, and it belongs to the orchestrator:

Workflow({
  scriptPath: "${CLAUDE_PLUGIN_ROOT}/skills/tech-lead/workflows/shapeup-run.js",
  args: <the RunArgs object>
})

Reach it through /ship (or the tech-lead skill), which opens the run properly — harness init run first, so the receipt exists. Do not hand-roll the round by calling this command once per task: the attempt loop, the T0 ratchet and the breakers are branches in that script, not steps a caller can be trusted to reproduce, and a session that rebuilds them by hand is the prose lane the cutover replaced. On a --tiny run or a spec with no committed scopes/*.md, the prose loop in skills/tech-lead/references/protocol.md still applies, unchanged and by design.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

build is a command published in the GitHub repository nguyenvanphituoc/shapeup-sdlc-plugin (2 stars, last pushed 14d ago), licensed MIT. It adds 15 tokens to every session and 420 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
