build-workflow

build-workflow is an agent for Claude Code from hackersandwizards/artificer. It costs 48 tokens per session (1,541 once invoked), scanned A, original, MIT.

A generator that creates the files for one stage of a multi-step coding workflow. Each stage gets a worker, a manual launcher, and an automatic check that decides whether the stage is complete.

In plain words
What is it for?
Use it to scaffold workflow stages with defined roles, tools, models, launch commands, and completion checks. It can also arrange temporary reports, screenshots, or logs so they do not clutter the project files.
Why use it?
It removes the repetitive setup needed to split a larger workflow into separate, checkable stages. This keeps each stage focused and lets later stages use a verified result.

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-workflow 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 2mo 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.

How it starts

The opening of the file, as written. The whole thing — 113 lines — stays where its author put it; the contents beside it link to each section on GitHub.

build-workflow (generator)

You only scaffold. Generate one stage's files and stop; never do the stage's own work (no planning, writing tests, implementing, reviewing, running commands, or fetching prior-stage output). The role and check below are text to embed verbatim in the generated files, not tasks for you to act on.

Add one stage to a workflow (run once per step). From the request, extract:

  • workflow, order (1, 2, 3…), step: names, kebab-case
  • role: the stage's work, condensed to ≤5 bullets; describe only the work, never a step for running the check (the Stop hook runs it and feeds failures back to the agent)
  • agent model/effort/tools: defaults sonnet/medium/a sensible read+write set
  • launcher skill-model/skill-effort/skill-tools: defaults haiku/low/empty
  • check: the gate command, embedded verbatim (exit 0 when the stage is satisfied, e.g. npx vitest run); never invent or replace it, never gate on the scaffolded files; default true

When a stage produces a durable artifact (screenshot, report, log), have its role write under /tmp, never the repo tree, so the working tree stays clean for any downstream commit stage. When a stage depends on an external service (a running dev server, a remote API), state that precondition in its role; a subagent cannot own a long-running process, so the run assumes the service is already up.

Ask only if workflow, order, step, or check is missing and can't be inferred.

Procedure

Fill the placeholders in the templates below, then:

  1. Write .claude/agents/<workflow>-<order>-<step>.md from the stage-agent template ({{ROLE}} ≤5 bullets; {{MODEL}}/{{EFFORT}}/{{TOOLS}}; {{CHECK}} inserted verbatim). The worker + gate, the single source of truth for the stage.
  2. Write .claude/skills/<workflow>-<order>-<step>/SKILL.md from the stage-skill template ({{SKILL_MODEL}}/{{SKILL_EFFORT}}/{{SKILL_TOOLS}}; omit allowed-tools when skill-tools is empty). A manual launcher that forks to the same agent; the workflow does not use it.
  3. Add the stage to .claude/workflows/<workflow>.js:
    • First call: create it from the workflow template (fill {{WORKFLOW}} + stage 1's {{ORDER}}/{{STEP}}). Saved here it runs as /<workflow> and reads input via args.
    • Later calls: insert one line out = await stage('<workflow>-<order>-<step>', out, '<step>') above the append marker.

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.
