spec
Skill31 starsChanged 31 days agoMITView on GitHub
Writes or reviews a change or decision spec with explicit tradeoffs and closeout criteria. Use for /spec, "spec this", "write a spec", review of a spec's open questions, or closing, archiving, and promoting a finished spec. Does not authorize implementation by itself.

JuliusBrusseeSkillbackprop
Bug → spec protocol. When a bug is found or a test fails, trace the cause, decide whether a new §V invariant would catch recurrence, append to §B. This is the one non-obvious thing SDD does that plan-then-execute doesn't. Triggers on test failure, bug report, post-mortem, or explicit user ask.

bastosSkillios-design-review
Review iOS app UI/UX design quality using Apple's design principles and the Liquid Glass-era design language from WWDC25/26. Use when asked for a design review, UX critique, visual design assessment, or evaluation of an app's interface quality, design intent, alignment with the new Apple design system, or usability. Triggers: "design review", "UX review", "visual design critique", "review the UI", "does this design work", "evaluate this interface", "design feedback", "Liquid Glass review".

ShreyRaviSkillplan-tune
Self-tuning question sensitivity + developer psychographic for gstack (v1: observational). Review which AskUserQuestion prompts fire across gstack skills, set per-question preferences (never-ask / always-ask / ask-only-for-one-way), inspect the dual-track profile (what you declared vs what your behavior suggests), and enable/disable question tuning. Conversational interface — no CLI syntax required.

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
6 rules. 0 are common, 6 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 145 edited versions we read keep these.
6
Distinctive
This author's own choices. Worth a look.
0
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Distinctive: line 8
Read the project's current state, instructions, existing spec, and relevant artifacts.
- Distinctive: line 27
Do not invent alternatives for a question with one answer.
- Distinctive: line 61
Verify completion against actual artifacts and acceptance checks.
- Distinctive: line 62
If a live change still needs release, use its authorized project release path.
- Distinctive: line 64
Update the state/tracker pointer in the same turn.
- Distinctive: line 66
If the runtime cannot move files, preserve the source and record the limitation.
“Common” is measured: kept by at least 6 in 10 of the 145 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
Spec
Read the project's current state, instructions, existing spec, and relevant artifacts. Follow its naming and storage conventions. Otherwise use the existing outbound/ or specs/ folder, or create specs/. Write one topic per file and link it from the project's state or tracker.
Write or review
Choose depth by the work:
- Change spec: concise problem, intended behavior, scope, implementation plan, and acceptance checks.
- Decision spec: enough evidence to assess the recommendation without repeating the investigation: methods, measurements, rejected approaches, uncertainty, costs, and sources.
For later execution, put the plan near the top. Name exact files, relevant anchors or patterns, configuration defaults, disable/revert path, tests, and acceptance checks. Prefer stable symbols or headings to unexplained line numbers.
Attribute choices accurately: user decisions, measurements, and model recommendations are different. Preserve exact user wording only when it defines a requirement or decision; do not quote every exchange. State risks, affected surfaces, and non-goals. Use an actual date and avoid invented shorthand.
For each unresolved choice the user must make, include:
- The question and necessary context.
- Two or three real options, each with gains, losses, implementation cost, and maintenance cost.
- A recommendation, the one piece of evidence it rests on (file and line, command output, URL, or the user's own words with their date) or "no evidence beyond judgment", and the condition that would change it. A recommendation with a confident reason and no source reads as a finding when it is a guess.
Do not invent alternatives for a question with one answer. Support claims that an option fixes a failure with the relevant issue, test, or failure record; otherwise mark that claim unverified.
File shape
Adapt sections to the task; omit empty sections except Closeout.
# <Topic>
Status: proposed
Created: <date>
Owner / attribution: <who made decisions or recommendations>
## Execution plan
<when implementation is intended>
## Problem and goal
## Scope and non-goals
## Evidence and rejected approaches
<for investigated decisions>
## Design
## Choices requiring the user's decision
<options, gains, losses, costs, recommendation, its evidence, reversal condition>
## Acceptance checks
<observable success and relevant negative cases>
## Closeout
- [ ] Verify the work or decision against the acceptance checks.
- [ ] Release any live artifact through the project's authorized release path.
- [ ] Move this spec to decisions/ or archive/, update Status, and retire the open pointer.Report the path and status briefly. A spec request alone authorizes the document, not the build. Honor explicit existing implementation authorization; do not reset it merely because a spec is being written.
Close or promote
- Verify completion against actual artifacts and acceptance checks. Report unresolved work as open.
- If a live change still needs release, use its authorized project release path. Do not infer permission for a new external action from "close the spec".
- Move the completed spec to decisions/ or archive/ using a real file move. Record whether it was applied or is only a decision record.
- Update the state/tracker pointer in the same turn. Confirm the outcome and new path.
If the runtime cannot move files, preserve the source and record the limitation. A copied destination with a surviving original is not a completed archive.

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.
