+- **`kyberforge`** — marketplace management toolkit and skill/agent factory. Contains `skill-author` (create/improve SKILL.md files), `skill-audit` (validate skills against agentskills.io spec), and `agent-author` (create/improve Claude Code + Copilot CLI agent definition files at plugin, project, or user scope) skills.

 ### Skills
 13 skills deployed directly to `~/.agents/skills/` via `install.sh`. Available as slash commands in Claude Code via `~/.claude/skills/ → ~/.agents/skills/` symlink. Factory and marketplace skills (`write-eval`, `write-skill`, `create-plugin`, `marketplace-architect`) have moved to the `kyberforge` plugin and are only available after plugin install.

 ## Recent changes
 
+- 2026-06-27 — `agent-author` skill added to kyberforge plugin. Creates and improves agent definition files for both Claude Code (`.md`) and GitHub Copilot CLI (`.agent.md`) from a single root directory input via `new-agent.sh`. Supports plugin, project, and user scope — scope auto-detected from root (`plugin.json` presence). File-by-file no-op scaffold; routing on file existence (neither → create, any exists → improve). `agents/sources.md` for provenance at plugin scope. No companion `agent-audit` skill (deferred, tracked in issue #11). ADR-0015 documents the dual-provider single-root scaffold decision.

 - 2026-06-20 — kyberforge plugin created and registered in `holocron` marketplace. Consolidates `create-plugin`, `marketplace-architect`, `write-skill`, and `write-eval` skills (previously in `.agents/skills/`) plus their evals, bundled scripts, references, and the plugin-marketplace-architecture research doc into a single installable plugin at `plugins/kyberforge/`. Plugin template (`templates/plugin/`) bundled into `plugins/kyberforge/skills/create-plugin/assets/plugin-template/` and removed from repo root. Evals moved from `.agents/evals/marketplace/` and `.agents/evals/factory/write-eval/` into `plugins/kyberforge/tests/evals/`. These four skills are no longer available as standalone slash commands — install the plugin to use them.
 
 - 2026-06-20 — Gitleaks secret scanning added. `scripts/setup-gitleaks.sh` installs gitleaks v8.24.2, seeds `.gitleaks.toml` (first run only — project-owned after that), and writes a managed pre-commit hook block that is replaced on re-run. `scripts/gitleaks.toml` is the base config template extending gitleaks defaults. `tests/test-setup-gitleaks.sh` covers 6 behaviors (reject non-git dir, config deploy, hook create, append, stale-block replace, idempotency). `.gitleaks.toml` in repo root adds path allowlist for `docs/research/` (high-entropy terminal captures). `gitleaks` skill added (`cross-cutting`) covering full lifecycle: install, update, tune allowlist, scan modes, resolve real findings. Key lesson: v8.24.2 uses `[allowlist]` (singular); v8.25.0+ uses `[[allowlists]]` — wrong syntax silently does nothing.
