vuestrata: Skill for Claude Code

.github/skills/vuestrata-spec-workflow/SKILL.md

vuestrata-spec-workflow is a skill for Claude Code from boussadjra/vuestrata. It costs 28 tokens per session (202 once invoked), scanned A, original, MIT.

A workflow for deciding when complex development work needs a written specification and how it should fit the existing backlog. It is intended for changes spanning multiple systems or affecting public behavior, documentation, settings, or architecture.

In plain words
What is it for?
Use it to find or extend an existing specification, or to create the required specification, plan, and task files before implementing non-trivial work.
Why use it?
It reduces the risk of starting implementation before the requirements, design, and project contracts are clear.

This is boussadjra/vuestrata's own configuration. It tells Claude Code how to work on vuestrata itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything vuestrata configures →

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

vuestrata-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 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.

What it actually says

Vuestrata Spec Workflow

Use this skill for work that should not jump straight to code.

Use When

  • the request spans multiple subsystems
  • public behavior, docs, env keys, or settings may change
  • the issue exposes architecture or contract drift

Rules

  1. Treat .specify/specs/ as the source of truth for non-trivial work.
  2. Reuse or extend an existing spec before creating a new one.
  3. New work belongs in .specify/specs/NNN-name/ with spec.md, plan.md, and tasks.md.
  4. Specs stay brownfield-specific and reflect repo reality, not generic templates.
  5. Before implementation, read the active spec, then plan, then tasks.
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.
