Activation
This is the description your AI agent reads to decide when to run this skill — the better it matches your request, the more reliably it fires.
Implement tasks from OpenSpec change or conversation plan. Use when the user wants to start implementing, continue implementation, or work through tasks.Key capabilities
- →Gather context from the current conversation
- →Pass OpenSpec change name to subagent
- →Summarize conversation plan for subagent
- →Pass explicit arguments to subagent
- →Launch Agent tool with `subagent_type: "osf-apply"`
- →Brief the user before launching subagent
How it works
The skill gathers context from the conversation, including OpenSpec change names or conversation plans, and then launches an `osf-apply` subagent with this context to implement tasks.
Inputs & outputs
When to use apply
- →Apply implementation plan
- →Execute change spec
- →Perform feature development
About this skill
Before launching the subagent, gather context from the current conversation:
- If an OpenSpec change name exists (from a prior /proposal or brainstorm that created a spec):
- Pass the change name — the subagent reads spec artifacts automatically
- If no spec but there's a conversation plan (from /feat, /fix, etc. brainstorm):
- Summarize: what was discussed, key decisions, requirements, scope
- If user provides explicit arguments:
- Pass those directly
Brief the user, then launch Agent tool with subagent_type: "osf-apply".
Pass context using this format:
With spec:
Change name: <change-name>
Without spec:
Plan summary: [what was discussed]
User choice: Implement directly without spec
Context: [key decisions, requirements, scope]
When not to use it
- →When the user wants to brainstorm or propose changes
- →When the user wants to create a spec
- →When the user does not want to implement tasks
Limitations
- →The skill itself does not implement code
- →It relies on an `osf-apply` subagent for implementation
- →Context gathering is limited to OpenSpec changes or conversation plans
How it compares
This skill acts as an adapter, translating user requests and conversation context into a structured input for a specialized implementation subagent, rather than directly performing the implementation.
