spec-workflow is a skill for Claude Code, Codex from znlgis/my-opencode-deepseek-config. It costs 104 tokens per session (1,554 once invoked), scanned A, original, MIT.

A lightweight workflow for planning a non-trivial software change with Markdown files tracked in Git.

In plain words
What is it for?
Use it to create a proposal, write specifications, document the design when needed, track implementation tasks, and archive completed work.
Why use it?
It keeps the reason for a change, its requirements, technical approach, and task checklist in durable project documents that people and agents can share.

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 1mo 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.

Spec-Driven Change Workflow

Plan and land a change through durable, git-tracked artifacts shared by humans and coding agents. Adapted (pure prompt, no tooling) from OpenSpec OPSX.

Philosophy

  • Enablers, not gates. Artifacts show what's possible next, not what you MUST do — edit an earlier artifact anytime.
  • Artifacts are the source of truth. Plans live as markdown in the repo, so they survive the session and stay greppable.
  • Brownfield-friendly + scale down. Delta specs (ADDED/MODIFIED/REMOVED/RENAMED) describe only what changes; skip the ceremony for a one-line fix.

Directory convention

openspec/
├── specs/<capability>/spec.md          ← source of truth (shipped behavior)
├── explorations/<topic>.md             ← optional pre-proposal notes
└── changes/
    ├── <change-id>/                    ← one in-flight change (kebab-case)
    │   ├── proposal.md                 ← WHY + WHAT (required)
    │   ├── design.md                   ← HOW (optional, only when warranted)
    │   ├── tasks.md                    ← checklist the apply step tracks (required)
    │   └── specs/<capability>/spec.md  ← delta: what this change adds/edits
    └── archive/YYYY-MM-DD-<change-id>/ ← completed changes, kept for history

Project-wide context and rules live in AGENTS.md — honor it in every artifact.

Action: propose

Create openspec/changes/<change-id>/ with a proposal, tasks, delta specs, and (when warranted) a design. Research existing code and openspec/specs/ first.

  • proposal.md (1–2 pages, WHY not HOW): ## Why, ## What Changes (mark BREAKING), ## Capabilities, ## Impact, an initially-empty ## Updates.
  • tasks.md: - [ ] checkboxes, grouped and ordered by dependency; each task fits one session and states its observable done-condition in the checkbox text (the verification that must pass to mark it [x]).
  • design.md: only if cross-cutting, a new pattern/dependency/data-model, or security/performance/migration complexity (Context · Goals/Non-Goals · Decisions · Risks · Migration · Open Questions).
  • skip_specs — a pure refactor, tooling, or docs change with no observable behavior change needs no spec contract. Set skip_specs: true in proposal.md and omit delta specs; the tasks checklist still carries its own done-conditions.

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.
