spec-writing
Skill0 starsChanged 7 months agoMITView on GitHub
Use when a feature, refactor, or workflow change is still underspecified and a short written spec should exist before issue creation or implementation. Trigger when goals, boundaries, users, or success criteria are still unclear. Do not use only because work spans multiple files; use `planning-workflow` or `issue-driven-workflow` once the problem is already clear enough to execute.

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
5 rules. 0 are common, 4 are distinctive, and 1 is very specific to this project.
0
Common
Most of the 15 edited versions we read keep these.
4
Distinctive
This author's own choices. Worth a look.
1
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 8
Write a short working spec before coding when the request is still loose.
- Distinctive: line 16
Write success criteria that can be validated later.
- Very specific: line 21
Prefer docs/product/ for the spec and link it from the issue doc before implementation starts.
- Distinctive: line 22
Stop once the work is clear enough to create an issue and a plan.
- Distinctive: line 35
follow-up tasks that already have a clear issue doc and plan
“Common” is measured: kept by at least 6 in 10 of the 15 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.

Spec Writing
Write a short working spec before coding when the request is still loose.
This skill is for problem framing, not task tracking.
Default flow
- State the problem, affected user or team, and desired outcome.
- Surface assumptions and unanswered questions early.
- Write success criteria that can be validated later.
- Record boundaries:
- in scope
- out of scope
- decisions that still need approval
- Prefer
docs/product/for the spec and link it from the issue doc before implementation starts. - Stop once the work is clear enough to create an issue and a plan.
Good fit
- new features with unclear shape
- refactors with behavior constraints
- architecture or workflow changes
- requests that would otherwise rely on chat memory
Avoid for
- typo fixes
- obvious one-line changes
- follow-up tasks that already have a clear issue doc and plan
Resources
- See
references/spec-checklist.mdfor a lean spec checklist. - Hand off to
planning-workflowafter the scope is stable and toissue-driven-workflowonce execution should be tracked.
Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
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.
