spec-anchored-agentic-development: Skill for Claude Code

.agents/skills/spec-to-tickets/SKILL.md

spec-to-tickets is a skill for Claude Code, Codex from w00fx/spec-anchored-agentic-development. It costs 38 tokens per session (2,604 once invoked), scanned A, original, MIT.

A planning tool that turns an approved capability specification into a set of complete delivery tasks. Each task is sized around one independently demonstrable result rather than one requirement or code layer.

In plain words
What is it for?
Use it to inspect a specification and create or update coherent implementation issues without changing production code or the specification.
Why use it?
It prevents work from being split into fragmented issues that are hard to own, review, or deliver. It also avoids losing related implementation and verification work across separate tickets.

Skill for Claude CodeCodex

Written for Claude Code and Codex: disable-model-invocation in frontmatter, but also agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents).

This is w00fx/spec-anchored-agentic-development's own configuration. It tells Claude Code and Codex how to work on spec-anchored-agentic-development itself, so it is not a mod to install elsewhere.

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-to-tickets 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 5d 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 — 342 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Convert one effective capability spec into a reviewed set of implementation issues. You may inspect the repository and publish or update issues. Do not modify production code or the capability spec.

Core law

One issue is one delivery task:

the smallest coherent unit that produces one meaningful, independently demonstrable outcome and justifies one owner, one branch, at most one PR, and one complete implementation-to-review lifecycle.

Optimize for cohesion and coordination cost, not for the smallest technically separable change.

Do not equate these units:

requirement ID       durable truth in the spec
issue / task         coherent delivery outcome
implementation step work inside the task's plan
verification case    evidence proving the task
specialist pass      mutation, QA, hardening, or review inside the task

One task may implement and verify many stable IDs, cross several layers, contain several test types, and use multiple fresh specialist agents.

1. Pin truth and inspect the seam

Read the complete capability spec and its canonical companion files. Resolve the exact committed revision that makes it effective on the protected/default branch.

Every task records:

capability ID
spec path
spec commit
stable IDs implemented and verified

If the spec is not effective, stop with SPEC_NOT_EFFECTIVE.

Inspect the relevant code, contracts, tests, ADRs, and repository conventions. Identify:

  • what already exists;
  • the missing delivery outcomes;
  • explicit milestones and checkpoints;
  • shared implementation contexts;
  • independent approval, rollout, rollback, migration, experiment, or operational boundaries.

Use capability language in titles and descriptions.

2. Draft outcome-oriented candidates

Use the spec's milestones, checkpoints, vertical validations, independently demonstrable experiments, and lifecycle boundaries as the first candidates. They are candidates, not automatic one-to-one tickets.

Build a milestone/checkpoint reconciliation before finalizing the candidates:

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.
