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

.agents/skills/implement-backlog/SKILL.md

implement-backlog is a skill for Claude Code, Codex from w00fx/spec-anchored-agentic-development. It costs 60 tokens per session (505 once invoked), scanned A, original, MIT.

An unattended workflow for implementing small, already-defined backlog issues. It follows a shared implementation process with automated review gates and does not originate new capabilities or architectural decisions.

In plain words
What is it for?
Use it to process bug fixes, technical debt, rule adjustments, reference-data proposals, and features already within scope. It prepares changes and pull requests while requiring human sign-off for business-value changes.
Why use it?
It allows eligible incremental work to move through planning, implementation, and review without a person guiding every step. Unclear issues stop for human clarification instead of being guessed.

Skill for Claude CodeCodex

Written for Claude Code and Codex: disable-model-invocation in frontmatter, but also agents/openai.yaml present. Also seen: mentions subagents; 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. Copy it as a starting point and replace the rules that are about this project. Everything spec-anchored-agentic-development 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

implement-backlog 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.

What it actually says

implement-backlog — unattended Owner adapter

First action: read .agents/protocols/implementation-protocol.md. No human answers mid-run. The parent worker is the Owner and must inspect every returned subagent diff before integrating it.

Mode identity

Invoke implement-backlog issue #<N> with the runtime's native explicit-skill syntax as the launcher's first user message. One qualified issue, one worktree/branch, at most one PR. New capabilities, semantic invention, broad architecture, and truth/oracle changes are out of scope.

Gate and pass providers

Protocol need Provider in this mode
Ambiguity / load-bearing decision NAMED_BLOCKER with exact question/evidence; never guess
Plan Owner writes a plan only when the qualified ticket, effective spec, repository policy and deterministic oracle fully determine it. Any unpinned decision aborts; there is no plan-review agent
Spec change SPEC_CHANGE_REQUIRED; proposal/comment only; never edit semantics
Scope/dependency/schema/data/external-action expansion Blocker, always
General code hardening general-code-reviewer; Owner inspects exact commit/report, scope and semantics before integrating
Mutation hardening mutation-hardener; Owner inspects exact commit/report and requires the 100% eligible-target contract
External specialized reviews Outside this run; separate monitor/pipeline/human owns them
Delivery Open PR, post link/outcome, terminal PR_READY_AWAITING_HUMAN; never monitor or claim merge

If either authoring agent returns a semantic/scope/oracle/dependency decision that the unattended policy cannot authorize, abort upstream. A subagent commit is never auto-cherry-picked without the Owner's recorded inspection.

Loop discipline

One issue per run. Release the claim on any blocker. Stop repeated non-progressing attempts and preserve commands, outputs, agent handoffs, Owner dispositions, and cost in the log.

Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

implement-backlog is a skill published in the GitHub repository w00fx/spec-anchored-agentic-development (5 stars, last pushed 4d ago), licensed MIT. It adds 60 tokens to every session and 505 once invoked, about $0.0003 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 2026-08-31.
