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
2 rules. 0 are common, 1 is distinctive, and 1 is very specific to this project.
0
Common
Most of the 148 edited versions we read keep these.
1
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 10
Prefer existing highest useful behavioural test seam.
- Very specific: line 12
Write docs/specs/<slug>.md unless repo prescribes another local path.
“Common” is measured: kept by at least 6 in 10 of the 148 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
Synthesise existing discussion; no new interview. Read relevant context.md, docs/Language.md, domain context, ADRs, current behaviour. Mark missing decisions explicitly; never invent agreement. No emojis.
Prefer existing highest useful behavioural test seam. Confirm seam with user unless already agreed. New seam: explain need. Cover distinct user outcomes, edge cases, failures; skip repetitive story boilerplate.
Write docs/specs/<slug>.md unless repo prescribes another local path. Status: draft, active, complete, superseded, or abandoned. Include owner/domain, related ADRs, tickets, superseded-by when relevant.
Sections: problem; intended behaviour; acceptance checks; implementation decisions/contracts; test seam + commands/prior art; exclusions; unresolved decisions. Paths useful for navigation; avoid brittle implementation recipes. Prototype snippet only when clearer than prose; label provenance.
Recommend breakdown when change spans independently verifiable slices, substantial migration, or exceeds fresh agent context. Small coherent change stays single spec. Never manufacture ticket count threshold.
Consequential durable tradeoff: recommend ADR + scoped small-model research/review subagent, e.g. Luna/Haiku if available. Spawn only when authorised. Domain definitions belong in Language.md, not framework glossary.
Local Markdown only. Preserve existing files; revise deliberately, never overwrite unrelated spec. No tracker publishing. Completion needs acceptance evidence; age never proves staleness. Preserve decision rationale through linked ADRs before proposing spec deletion; deletion always explicit approval.
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.

- 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.
