Post-implementation review of PR #93 (issue #89's apm.yml-native retargeting of skill-author/skill-audit/agent-author/agent-audit) found four confirmed defects across the four scripts' apm.yml `type:` walk-up logic: - field-inventory.md's apm-agent-allowlist was missing `source_keys`, contradicting agent-author/SKILL.md's own instruction (Step 5 checklist) to allow it at plugin/APM scope — a correctly-authored file with source_keys failed validate.sh. - validate.sh's APM_TYPE_RE and validate-provenance.sh's TYPE_RE disagreed: the former tolerated a quoted `type: "skill"` value, the latter didn't, despite agent-audit/SKILL.md explicitly documenting that validate-provenance.sh walks up "the same way validate.sh does". Both also used `\b` word-boundary matching, which false-matches a malformed value like `type: prompts-only` on the `prompts` prefix. Unified both regexes to be quote-tolerant and require an exact value. - All four scripts' `.git` project-boundary check used isdir()/[[ -d ]], which misses git worktrees where `.git` is a regular file (`gitdir: ...`) rather than a directory. Switched to exists()/[[ -e ]]. - new-agent.sh and new-skill.sh had the same quote-intolerance as above via inline `grep -qE` calls (new-skill.sh's also had the `\b` false-match bug); replaced both with a shared-shape `is_apm_package_manifest` bash helper matching the Python regex's semantics. Four other findings from the same review turned out not to be bugs: a bare `plugin.json` no longer signaling plugin scope is documented, intentional behavior (agent-audit/SKILL.md:30, agent-author/SKILL.md:87), deferred to issue #90's real plugin.json-to-apm.yml conversion — not something this fix should reverse. Verified via direct reproduction of each defect plus the full test suite: 147/147 bats tests, 39/39 shell-script tests, 12/12 summary categories. Refs: #89
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 at plugin/APM, project, or user scope. Project and user scope always generate a Claude Code + Copilot CLI file pair (.md + .agent.md) in one pass. Plugin/APM scope generates a single vendor-neutral .apm/agents/<name>.agent.md file instead — no separate Claude Code / Copilot split, since apm compile has no per-target field integrator (see ADR-0016). Also applies improvement signals — grill output, inline feedback, session context — to existing agent files. Bumps the version after every change: the resolved package's apm.yml at plugin/APM scope (minor for new agents, patch for improvements); project/user scope has no manifest to bump.
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 packages/my-package/ # plugin/APM scope if packages/my-package/apm.yml has a type: field
bash scripts/new-agent.sh deploy-assistant .
bash scripts/new-agent.sh security-reviewer ~
