askit-build-output-style
Purpose
Author a Claude Code output style: a definition that changes how the agent formats and frames its responses (for example an explanatory or terse mode). Output styles are CLAUDE-ONLY - Codex and the wider agentskills.io ecosystem have no equivalent (Standard sec 2.3) - so this skill emits no Codex artifact and the authored component declares agent-targets: [claude]. Two modes: create scaffolds a new output style; improve refines an existing one. Authoring depth is in references/authoring-output-styles.md. Follows the shared builder contract (../../docs/reference/builder-pattern.md).
When to use
When the user asks to create, scaffold, write, or improve a Claude Code output style (a response mode or response-formatting definition).
create mode
- Brief interview: the style's purpose (when Claude should use it), the response shape it enforces (structure, tone, length), and any required elements. Skip if in context.
- Scaffold the output-style markdown (copy
templates/output-style.md): a name, a description of when it applies, and the response-formatting instructions.
- Declare
agent-targets: [claude] (Claude-only) and state the asymmetry plainly; do not emit a Codex artifact.
- Register it in
library.json components.outputStyles as { name, version, tier, status }.
- Evaluate (
node scripts/evaluate.mjs . --json).
improve mode
- Run evaluate and read findings.
- Tighten the description (when-to-use) and the formatting instructions; remove ambiguity about when the style applies and what it requires.
- Re-run to confirm.
Scope
Claude-only (sec 2.3). The build SKILL is portable, but the artifact it produces runs only on Claude Code; state this clearly rather than silently emitting nothing for other targets (the F-06 expectation-setting principle). Output styles are an Advanced, agent-specific capability.
