Project Capability Authoring
Turn a demonstrated repeated project workflow into a small local capability.
This skill creates project-local skills and scripts. It does not change Core,
build MCP servers, or write persistent memory.
When To Use
- Meditation identifies a repeated workflow or deterministic task worth keeping.
- A manual task has recurred and produced inconsistent results or avoidable
mistakes.
- The user asks to make a project workflow reusable, repeatable, or scripted.
Do not use this for a one-off task, an untested aspiration, shared continuity,
or a personal preference.
Author A Capability
Prove the pattern: name the repeated workflow, the concrete failure or
inconsistency it prevents, and the project users who benefit.
Scan prior art: search existing .github/skills/, scripts/, and
project guidance. Extend an existing capability when it already covers the
workflow.
Choose the smallest placement:
| Need |
Destination |
| Guided repeatable workflow |
.github/skills/<name>/SKILL.md |
| Workflow with deterministic automation |
.github/skills/<name>/scripts/<task>.cjs |
| Cross-cutting project automation |
scripts/<task>.cjs |
Define the contract: write the trigger, inputs, outputs, failure mode,
and one should-fire plus one should-not-fire example. A script must state its
prerequisites, accepted arguments, and validation command.
Preview the change: show every proposed file and the validation plan.
Obtain explicit user approval before creating or modifying project files.
Validate: run the narrowest executable check for a script, and exercise
the skill's should-fire and should-not-fire cases. Run diagnostics on every
changed file.
Report: state the extracted pattern, artifact path, validation evidence,
and why a new capability was warranted instead of a one-off solution.
Memory Boundary
Meditation may separately recommend user memory, repository memory, a handoff,
or a chronicle. Do not write any persistent memory from this skill. A memory
write requires the relevant explicit user request or approval and must pass the
PII filter.
Anti-Patterns
| Anti-pattern |
Correction |
| Creating a skill after one routine task |
Require a demonstrated repeat or concrete failure first. |
| Copying a skill that already exists locally |
Extend the existing capability after the prior-art scan. |
| Hiding a destructive script behind a skill |
Preview the command and require explicit approval before execution. |
| Creating project files while summarizing meditation |
Meditation routes the candidate; this skill previews and validates it. |
| Treating an MCP server as a project script |
Evaluate MCP construction separately; it is not this skill's scope. |
Would Revise If
Revisit by 2026-11-15 if real meditations produce no demonstrated reusable
workflow, authors repeatedly choose the wrong local placement, or generated
capabilities fail their focused validation more than once.
