## Why
agent-author produces agents/sources.md at plugin scope to record which
research sources informed which agent files. agent-audit had no way to
validate this chain, leaving stale or missing provenance undetected.
## Implementation Notes
Validation is per-pair (the given agent file + its counterpart) rather
than plugin-wide, keeping the scope consistent with validate.sh. The
script exits 0 silently for non-plugin-scope agents.
source_keys is top-level in both CC .md and Copilot .agent.md files
(not under metadata:) to avoid conflict with Copilot's own metadata
field semantics. Checks 0, 1, 2, 4, 5, 6 mirror the skill provenance
set; upstream research-doc cross-reference checks (7, 8) are deferred.
agent-author Steps 2, 3, and 4 updated to formally specify the
agents/sources.md format and instruct authors to add source_keys to
both files when research sources are in context.

## 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.
