Skill0 starsChanged 25 days agoMITView on GitHub
Write an implementation spec for a feature or bug fix from a ticket or requirements, or, in rfc mode, a structured RFC for others to review (context, goals, proposal, alternatives, risks, rollout). Use on "write a spec", "plan the implementation", "how should we build this", "create an RFC", "design doc", "/spec", "/spec rfc".

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
3 rules. 0 are common, 1 is distinctive, and 2 are very specific to this project.
0
Common
Most of the 145 edited versions we read keep these.
1
Distinctive
This author's own choices. Worth a look.
2
Very specific
Tied to their project's names, files or tools. Probably skip.
- Common
- Distinctive
- Very specific
- Very specific: line 13
Follow ../../shared/policy.md.
- Very specific: line 16
Use an existing context.md for this ticket if there is one.
- Distinctive: line 20
Read the code the context maps.
“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
Follow ../../shared/policy.md. Run dev-skills:project-profile if not loaded this session.
1. Context
Use an existing context.md for this ticket if there is one; otherwise run
dev-skills:gather-context first.
2. Choose the approach
Read the code the context maps. Consider the realistic options (usually 1-3). Pick the one that solves the requirement at the root with the smallest change that fits the codebase's existing patterns; reuse what already exists.
autonomous/balanced: decide and record why in the spec.guided: present the options with trade-offs and a recommendation; wait for the choice.
3. Write it
Save spec.md next to context.md.
Default mode (for the developer):
# Spec — <TICKET> <title>
## Approach
<what and why, 3-6 lines>
## Changes
- `path` — <change>
## Data / migrations
## API / contract changes
## Flags and rollout
## Risks and edge cases
## Testing
<pointer to qa-plan.md, or the test cases if small>
## AssumedOmit empty sections.
rfc mode (for reviewers): same research, more structure and less code detail:
Context · Problem · Goals / Non-goals · Proposal (with a diagram when flows or components change) ·
Alternatives considered (and why not) · Risks and mitigations · Rollout and rollback ·
Testing strategy · Open questions · Timeline/effort.
Save as rfc.md. Publishing it to Notion/Confluence/Docs goes to the confirmation list.
4. QA plan
Unless the caller says otherwise, run dev-skills:qa-plan on the spec.
In guided, show the spec and QA plan and wait for approval before returning. Otherwise return the
paths and a 5-line summary.
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.
