dzhngSkillimplement-spec-with-codex
Run [implement-spec](../implement-spec/SKILL.md) with Codex doing the implementation passes while you orchestrate, integrate, and review. Use when the user asks to implement a spec with Codex, or to run implement-spec with Codex as the implementer.
Also in 4 projects that use this
dzhngSkillclose-spec
When a spec under specs/<feature>/ is done shipping (a write-spec build, or any planned task that produced a spec), archive it to specs/done/ and rewrite it from a build-plan into a durable rationale — the why, the principles, the invariants — pointing back to the real code for the how. Use when implementation has landed and the plan no longer matches what shipped, or the user says a feature/spec is finished. Pairs with [write-spec](../write-spec/SKILL.md) (the plan this closes) and [review](../review/SKILL.md) (run before closing).

Also in 3 projects that use this
transitive-bullshitSkillcompare-screenshots
Compare screenshots against the intended design, distinguishing approved references from historical baselines. Use for iterative implementation matching, before/after visual review, objective image telemetry, or checking a lone capture for flat, empty, or badly framed content.

How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

The file
We split this skill into the rules it gives an agent
4 rules. 0 are common, 1 is distinctive, and 3 are very specific to this project.
0
Common
Most of the 100 edited versions we read keep these.
1
Distinctive
This author's own choices. Worth a look.
3
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 12
Read the task, the requirements and acceptance criteria it serves.
- Very specific: line 13
Tests first: if the task has no test yet, delegate to test-engineer.
- Very specific: line 17
Run code-reviewer; if numbers changed, also numerical-auditor.
- Very specific: line 21
When all tasks are ticked, tick the acceptance criteria in spec.md, set status Implementing → leave Done to the maintainer, and suggest …
“Common” is measured: kept by at least 6 in 10 of the 100 edited versions of this file we could read. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
<!-- Generated from .agents/skills/implement-spec/SKILL.md by scripts/sync_agents.py. Edit the source, not this file. -->Preconditions: the spec is Approved and has plan.md and tasks.md. If not, stop and
use /spec-new.
Loop over unticked tasks in order (respect [P] only when working in parallel worktrees):
- Read the task, the requirements and acceptance criteria it serves.
- Tests first: if the task has no test yet, delegate to
test-engineer; run the tests and confirm they fail for the expected reason. - Implement the minimum to make them pass, following AGENTS.md hard rules.
uv run just checkmust pass.- Run
code-reviewer; if numbers changed, alsonumerical-auditor. Fix blocking findings. - Tick the task in
tasks.md, commit with a Conventional Commit message citing the spec:feat(<scope>): <what> [SPEC-NNNN R<n>], signed off (git commit -s).
When all tasks are ticked, tick the acceptance criteria in spec.md, set status
Implementing → leave Done to the maintainer, and suggest /pre-pr.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
