lilangMaxSkillsoak-test
Generate a soak test protocol for extended play sessions. Defines what to observe, measure, and log during long play sessions to surface slow leaks, fatigue effects, and edge cases that only appear after sustained play. Primarily used in Polish and Release phases.

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, 5 are distinctive, and 0 are very specific to this project.
0
Common
Most of the 179 edited versions we read keep these.
5
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
Use this skill after debate recommends validation or when the human asks to see or test a direction before production planning.
- Distinctive: line 12
Read the debate conclusion and relevant project context.
- Distinctive: line 16
Create only the prototype.
- Distinctive: line 32
Do not install a framework solely for a prototype without approval.
- Distinctive: line 47
Do not silently promote prototype code into production.
“Common” is measured: kept by at least 6 in 10 of the 179 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
Prototype
Use this skill after debate recommends validation or when the human asks to see or test a direction before production planning.
Process
- Read the debate conclusion and relevant project context.
- Name the single primary assumption being validated.
- Recommend the cheapest useful prototype format.
- Define success/rejection criteria and an output location under
prototypes/. - Create only the prototype; avoid production architecture unless the task is explicitly a technical proof.
- Present focused review questions.
- On feedback, revise the same direction, replace it, approve it, or stop.
- Record approved direction, rejected assumptions, and explicit production exclusions
under
## Durable Decisionsincontext/project-overview.md, creating the file fromtemplates/project-overview.template.mdif it does not exist yet.
Supported Forms
- wireframe or user-flow diagram
- static visual concept
- interactive HTML/CSS/JS
- prototype using an already-installed project stack
- API/integration/AI/animation/offline proof of concept
- architecture or data-flow diagram
Do not install a framework solely for a prototype without approval.
Human Review
Ask:
- Is the purpose or tested assumption clear?
- Is the main flow/behavior correct?
- What should be removed, revised, or replaced?
- Is the direction approved for specification?
Rules
- Prototype only what needs validation.
- Label shortcuts and mocked behavior.
- Do not silently promote prototype code into production.
- Iterate rather than generating unrelated alternatives unless replacement is requested.
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.
