## Why
skill-author explicitly excludes agent definition files ("Do not use to author
agent definition files"). No factory skill existed to create or improve the
.md / .agent.md files that define Claude Code subagents and Copilot CLI agents
in a plugin, project, or user scope. This fills that gap.
## Implementation Notes
Single-root scaffold convention: new-agent.sh <name> <root> derives both
provider file paths from the root by convention — plugin scope (plugin.json
present) writes both files into <root>/agents/; non-plugin scope writes
.claude/agents/<name>.md and .github/agents/<name>.agent.md. This keeps
input minimal while always generating both provider files. See ADR-0015.
Routing is file-level (not directory-level like skill-author): neither file
exists → create flow; at least one exists → improve flow; scaffold is a
file-by-file no-op so retries are safe.
No companion agent-audit skill — inline validation in the close step covers
the simpler agent field contract. agent-audit is tracked as a follow-on.
## Impact
Closes the skill-author gap for agent definitions. Follow-ons tracked in
Gitea #11: agent-audit skill and --copilot-dest override flag for non-standard
Copilot project paths.

agent-author
Creates and improves agent definition files for Claude Code and GitHub Copilot CLI.
What it does
Scaffolds and fills in agent definition files (.md for Claude Code, .agent.md for Copilot CLI) at plugin, project, or user scope. Always generates both provider files in one pass. Also applies improvement signals — grill output, inline feedback, session context — to existing agent files.
Before you start
Have ready: the agent's name (kebab-case), the root directory (plugin root, project root, or ~), a one-sentence purpose, and the triggering condition (when should the runtime delegate to this agent?).
Usage
/agent-author
Manual scaffold (human workflow):
bash scripts/new-agent.sh <agent-name> <root>
# Examples:
bash scripts/new-agent.sh code-reviewer plugins/kyberforge/
bash scripts/new-agent.sh deploy-assistant .
bash scripts/new-agent.sh security-reviewer ~
