 #### Closed director fleet (`src/agent/directors/`)
 
-Every shipped specialist is a **director package** — a prompt-first `DirectorPackage` (system prompt, tool envelope, spawn rights, nudge budget, report contract, `modelRole`, fleet authority `tier`) registered in a **closed** set of 18 ids. There is no catch-all worker: `spawn_agent` without `agent` or non-general `intent`, and `spawn_agent(intent="general")`, fail closed so the primary reclassifies. Nested directors with a spawn allowlist reject off-list children at `spawn_agent` dispatch time (not prompt-only). Skywalker is the primary session identity: `spawn_agent(agent="skywalker")` is refused, and `directorProfiles()` omits it from the spawn catalog.

 ## Multi-agent (fleet agents)
 
-The primary session is always **orchestrator** (single-agent mode is gone). Its identity is **Skywalker** (product name remains Corbits Code; when asked its name, answer Skywalker): classify work, DIY tiny/single-file/one-route product edits, dispatch a **closed fleet of 18 directors** for substantial work, track the fleet, and synthesize. Product mutation tools (`write_file` / `edit_file` / `delete_file`) are mounted on the primary (CORE / `SKYWALKER_TOOLS`) — path tools are the DIY surface; spawn remains the default for substantial, multi-file, parallel, or specialist work. Shell file-writes stay denied. MCP tools are not re-filtered by a product-write deny list (that list is gone). There is no static per-package write-path declaration (CL-6952 removed it — no shipped director ever set one). A concurrent dispatch landing on the same working directory as another still-running lane is recorded as a `conflict` intervention, not blocked. Operator slash recipes (`/implement`, `/plan`, `/refactor`, `/review`, `/pull-request-review`, `/create-issue`, `/scribe`, `/interview`, `/ast-grep`) tell Skywalker which directors to spawn for substantial work; tiny/bounded edits may run on the primary.

 There is **no catch-all worker**. `spawn_agent` requires `agent=…` or a non-general `intent` (implement/explore/plan/review→critic); bare dispatch and `intent=general` are refused. Named `spawn_agent(agent=…)` selects a director package without requiring a plugin profile, except `skywalker` which is the primary session identity and is refused as a spawned worker. Nested spawn is runtime-enforced: only skywalker (full fleet allowlist) and greybeard (intern/explorer/critic) may spawn; other workers have no fleet tools. Primary omits an allowlist so plugin profiles remain reachable from the main session.
