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. About 0 are common, 1 is distinctive, and 2 are very specific to this project.
≈0
Common · estimate
Many files like this have a rule of this kind.
≈1
Distinctive · estimate
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
- Distinctive: line 6
Only for requested delegation, read Poteto.
- Very specific: line 15
Keep chores inline on Opus.
- Very specific: line 29

≈ “Common” is an estimate: at least 1 in 5 of the 350,495 skill files we read have a rule of the same kind, not the same words. “Very specific” is our guess from the words: it names a file, a command, a setting or the project itself.
Files
Only for requested delegation, read Poteto.
Use tool choice.
config/model-routing.json owns routing; omit subjective prompt scores.
- Owner: Opus 5.5
xhighfor daily work, plans, code, UI. - Sol
xhighreviews PRs via/codex; if unavailable, label a clean-context Opusxhighpass and disclose missing different-family coverage. - Opus owns UI, copy, API design (taste >= 8); if unavailable, report the UI lane blocked.
- Keep chores inline on Opus. Use Sol
xhighfor user-selected Codex execution, computer use, or investigation. - Route only Opus/Sol; never
max. If neither is available, report the lane blocked. Owner preference overrides historical scores. - The user explicitly authorizes a different-family pass; model preference is not spawning consent.
ultraneeds explicit delegation or/swarm. Pro mode, persisted reasoning, programmatic tools, explicit cache: API-only unless exposed.
Without delegation, keep lanes inline. Authorized briefs bound objective, inputs, exclusions, evidence, stop. One owner keeps architecture, priority, risk, synthesis and acceptance.
Capacity
Capacity: /stay-within-limits host meter, else unknown. Never infer from tokens/cost; remove routes, never lower quality.
Promotion
xhigh is owner-selected, not benchmark-promoted.
Before unrequested default changes run agent-evals/context-ablation/: vary one context group, fix tasks/scoring, prefer lower cost only among quality-equivalent results. Record winner in routing config.
Packet and source: authorized delegation only.
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.
