# Skillify

Capture what this session learned as a skill the next session can run without the conversation. Use the host's native authoring tools for package mechanics; this skill owns workflow extraction, personal conventions, and the [catalog package rules](references/package-rules.md).

## Workflow

1. **Extract from the session**: the goal, the user's trigger phrases, the exact commands that worked (with flags), the decisions and why, the dead ends, and the tools required; drop session-specific paths, one-off values, and secrets.
1. **Apply the admission rule**: in [package rules](references/package-rules.md), first extend an existing owner or use project scope. A new global entry needs a distinct recurring trigger, demonstrated behavioral value, and space within the discovery and instruction budgets. If only general product knowledge remains, use documentation instead.
1. **Check the catalog**: `skills list` and `skills list -g` (preview `gh skill list` also scans every host directory), then read any neighbor with an overlapping description; extend it when the workflow is the same, write a new skill only for a distinct trigger, and link neighbors instead of copying them.
1. **Choose the scope**:
   - **Global** (reusable, tool-generic): `~/.agents/skills/<name>/`, the `skills/` directory of the dot repository, whose `dot-skills` skill owns registration (link declaration) and `mise run check:skills`. Installation or tooling changes also need their affected tests.
   - **Local** (repository-specific commands, data, or conventions): `.agents/skills/<name>/` in the project; add `.claude/skills -> ../.agents/skills` if missing per [agent-project](../agent-project/SKILL.md). In the dot repository, local skills also register through `dot-skills`.
1. **Write from the template**: copy [skill.md](templates/skill.md) and apply the size and output-efficiency rules in [package rules](references/package-rules.md); long configs and examples go to `references/`.
1. **Validate**: frontmatter `name` equals the directory, every link resolves, every resource is reachable from its owner, and `mise run check:skills` passes for a global skill.
1. **Test behavior**: follow the [adoption check](references/adoption-check.md) for substantial additions or routing changes: a natural trigger, a neighboring task, and an observable outcome in an isolated fixture. Keep paid or external effects within scope and report unavailable host validation separately.
1. **Report**: the path, the description, and the scope.

## Extracting from AGENTS.md

Keep durable preferences in the global persona and repository invariants in project `AGENTS.md`. Move procedures into the existing owning skill where possible; create a global or local skill only for a distinct reusable workflow. Leave a routing cue and re-run [repository-docs](../repository-docs/SKILL.md).

## Gotchas

- **Descriptions route, bodies instruct**: the description decides when the skill loads; the body decides what happens. Do not summarize the workflow in the description.
- **Keep dates current**: set `created` and `updated` to today; bump `updated` on every later edit.
- **Follow vendor policy for third-party content**: when the workflow came from an external skill, follow the shared [vendor-skill policy](../agent-project/references/vendor-skills.md) instead of retyping it.
- **Promote or publish per portability**: promoting a guide to a package, publishing one standalone, or adding `agents/openai.yaml` follows [portability](references/portability.md).

## Documentation

- [Agent Skills specification](https://agentskills.io/specification)
- [Catalog and usage review](references/catalog-review.md): measure discovery cost and bounded activation evidence before adding or retiring global entries.
