Defame1297 54d7bd80ba docs: rule host built-ins out of the routing target universe
Closes the second open design decision on PR #103. The `/compact` finding was
recorded as a false positive needing an allowlist or a suppression mechanism.
It is neither: the routing universe is the apm marketplace, so a target either
resolves to a skill or an agent or it does not resolve, and `/compact`,
`/clear` and `/init` are Claude Code slash commands with no counterpart in
Copilot CLI or Codex. `.apm/` source compiles for all three, so a
vendor-neutral description routing to one is a portability defect and the hard
FAIL is a true positive.

An allowlist was rejected for a concrete reason, not a stylistic one: it
answers a different question ("does this exist on some host?"), it cannot
answer that portably from a single source file, and it goes stale the next
time a host ships a command — reintroducing the same-commit-two-verdicts
failure ADR-0020 already closed for deployed trees.

Nothing is blocked today: zero of the 43 descriptions name a host built-in,
and an author who needs to mention one writes it un-slashed, which is not
route notation and carries no routing claim.

Recorded in ADR-0020 and in both author-facing contract references, so the
next agent reads the decision rather than "fixing" the gate.

ADR: 0020

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 ~

Rows marked (source-only) exist in the authoring source (.apm/skills/agent-author/) but are not present in an installed plugin: scripts/sync-plugin-content.sh strips <category>/<name>/tests when it generates the flat mirror, because these are dev-time fixtures no plugin host needs to discover (ADR-0017). Run them from a repo checkout, not from an install. The assets/templates/ rows above are unaffected — the exclusion is depth-scoped to <category>/<name>/tests, so template trees that themselves contain a tests/ directory ship intact.
