spec-workflow

A planning guide for medium-to-large software changes that turns unclear requirements into an agreed design and task plan before implementation.

In plain words
What is it for?
Use it to define requirements, technical designs, acceptance criteria, implementation steps, and staged plans for new features or cross-module work.
Why use it?
It reduces confusion and rework when a change spans several modules, files, user flows, or architectural decisions.

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

spec-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 2d 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 — 162 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Sibling skills (local only)

Sibling CloudBase skills ship beside this skill. Use local relative paths such as ../auth-tool-cloudbase/SKILL.md.

If a referenced sibling skill file is missing from this environment, ask the user to install the full CloudBase plugin (or the missing skill). Do not HTTP-fetch remote skill or protocol markdown into the agent context.

Spec Workflow

Activation Contract

Use this first when

  • The request is a new feature, multi-step product change, cross-module integration, or architecture/design task.
  • Acceptance criteria are unclear and need to be made explicit before implementation.
  • The work involves multiple files, user flows, database design, or UI design that needs staged confirmation.

Read before writing code if

  • You are unsure whether the task should go straight to coding or should first go through requirements, design, and task planning.
  • The request mentions a new page, a new system, a redesign, a workflow, or a multi-module refactor.

Then also read

  • Frontend page or visual design work -> ../ui-design/SKILL.md
  • Advanced data-model work -> ../data-model-creation/SKILL.md

Do NOT use for

  • Small bug fixes with clear scope.
  • One-file documentation updates.
  • Straightforward config changes.
  • Tiny refactors where the user already gave exact implementation instructions.

Common mistakes / gotchas

  • Jumping into coding before acceptance criteria are explicit.
  • Skipping user confirmation between requirements, design, and tasks.
  • Writing vague tasks that do not map back to user-visible outcomes.
  • Treating UI work as purely technical implementation without clarifying design intent.

Minimal checklist

  • Decide whether the change really needs the full spec flow.
  • If yes, stop and produce requirements first.
  • If the change is small, low-risk, and acceptance is already clear, allow direct execution without forcing spec artifacts.
  • Use EARS-style acceptance criteria.
  • Get confirmation before moving to the next phase.

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.

spec-workflow is a skill published in the GitHub repository TencentCloudBase/CloudBase-AI-Toolkit (1,087 stars, last pushed 2d ago), licensed MIT. It adds 38 tokens to every session and 1,071 once invoked, about $0.0002 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 2026-08-30.
