Defame1297 4a5c3c0cff feat(kyberforge): enforce the ADR-0020 context contract for skills and agents

Skill name+description pairs are preloaded into every session, costing
~6,200 tokens across 39 skills before any skill is invoked. The authoring
rules mandated that growth: skill-author:104 and description-quality.md:21
both required padding, while skill-author:102 (the deflating rule) had no
FAIL condition behind it.

Gates (blocking, no baseline file):
- description 250 chars SUGGESTION / 400 FAIL, measured on the folded
  YAML value
- body-only 600 words SUGGESTION / 900 FAIL, independent of the unchanged
  whole-file 2770-word / 500-line spec backstop
- every boundary-clause routing target must resolve to a real skill or
  agent; catches skill-improve, neuledge-context and gitea-labels
- agents take the description gates but deliberately no body gate; a test
  pins that absence

Vale: DescriptionOpener widened to ^This\b, new CompositionNote rule
banning architecture notes from descriptions. 10 hits, 0 false positives.

Kyberforge's own four skills retrofitted: descriptions 3,364 -> 938 chars
(-72%), bodies 8,306 -> 2,487 words (-70%), all via the apm-workflow
dispatch pattern. Fixes the skill-improve dangling route and the
agent-author misroute to manual review.

Also fixes a pre-existing false positive where any line-initial 'read '
was flagged as interactive input, which had already caused two scripts to
be rewritten around it.

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 ~

Files

File	Purpose
`SKILL.md`	Skill instructions for agents — gotchas, the create/improve dispatch table, the scope dispatch table, the shared gates, and validation/close
`scripts/new-agent.sh`	Scaffolds agent definition file(s) from templates — a single `.apm/agents/<name>.agent.md` at plugin/APM scope, or a Claude Code + Copilot CLI pair at project/user scope
`references/create.md`	Create flow: prerequisites, scaffold and scope walk-up, what to fill in, package-root `sources.md`
`references/improve.md`	Improve flow: signal verification, root-cause grouping, generalizing, delegation over growth, ADR-0020 retrofit
`references/contract.md`	Description and body contract: three-part description shape, 250/400 tiers, delegation rule in place of a body word gate, invocation axis
`references/plugin-scope.md`	Plugin/APM scope field rules for the single vendor-neutral file, plus its pre-audit checklist
`references/project-user-scope.md`	Project/user scope field rules for the Claude Code + Copilot pair, both Copilot formats, plus its pre-audit checklist
`references/deployment-modes.md`	Scope hierarchy and precedence, scoped identifiers, cache isolation, path conventions
`references/scripts.md`	Conventions for new-agent.sh and the templates it copies: contract, template variables, file placement, error messages
`references/sources.md`	Research provenance — sources that informed this skill
`assets/templates/claude-code.md`	Annotated Claude Code agent definition template (project/user scope)
`assets/templates/copilot.agent.md.template`	Annotated Copilot CLI agent definition template (project/user scope)
`assets/templates/apm-agent.md`	Annotated vendor-neutral APM agent definition template (plugin/APM scope)
`tests/new-agent.bats`	(source-only) bats tests for `scripts/new-agent.sh`
`assets/README.md`	Directory meta-documentation for assets/
`references/README.md`	Directory meta-documentation for references/
`scripts/README.md`	Directory meta-documentation for scripts/
`tests/README.md`	(source-only) bats dependency instructions and run command

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.
