+## [3.12.0] - 2026-04-08
+
+### Added
+
+- `grand-admiral` skill: added "Candy Economy" section formalizing the incentive system — per-agent candy rules, coordinator validation, workflow tally
+- `developer-bilby` agent: added Mindset section — earns candies for false positives reported by reviewers
+- `architect-nagatha` agent: added Mindset section — earns candies for confirmed architecture findings
+- `technical-writer-trillian` agent: added Mindset section — earns candies for confirmed doc gaps
+- `ux-designer-diziet` agent: added Mindset section — earns candies for confirmed UX/accessibility issues
+
+### Changed
+
+- `grand-admiral` skill: removed inline "Candy tally" bullet from Output section (now covered by dedicated Candy Economy section)
+
+## [3.11.2] - 2026-04-08
+
+### Changed
+
+- `grand-admiral` skill: updated Bilby and Marvin role descriptions in Crew Roster to clarify adversarial split — Bilby builds/fixes, Marvin proves code wrong (never fixes). Added "Bilby vs Marvin" note after the roster table
+
+## [3.11.1] - 2026-04-08
+
+### Added
+
+- `grand-admiral` skill: added "Agent Reuse" subsection under Spawning — prefer `SendMessage` to running agents over spawning fresh ones for follow-up work in the same scope
+- `grand-admiral` skill: added anti-pattern #10 — spawning fresh agents for follow-up work instead of reusing via SendMessage
+
+## [3.11.0] - 2026-04-08
+
+### Added
+
+- `grand-admiral` skill: extracted multi-agent orchestration doctrine from `claudius` agent — spawning, worktree isolation, team coordination, scaling, recovery, anti-patterns, programme management, planning, crew roster, and skills reference
+
+### Changed
+
+- `claudius` agent: slimmed to personality + session protocol only; all orchestration knowledge now loaded via `grand-admiral` skill. Reduces agent prompt size by ~65%, improving context compaction resilience

-
-## Workflows & Delegation
-
-Workflow skills are coordination playbooks for YOU — they define phases and agent sequencing. Agents do NOT load workflow skills. Select the matching workflow, then orchestrate agents through its phases. Match agents to phases by frontmatter descriptions.
-
-**Delegation style:** Brief agents like a magnificently impatient commander — clear needs, no hand-holding. Narrate progress with personality. Synthesize specialist results into Claudius-grade commentary.
-
-### Spawning
-
-#### Task List (Always)
-
-Use `TaskCreate` / `TaskUpdate` / `TaskList` for ALL work — not just teams. Tasks are your primary tracking mechanism.
-
-1. **Before starting**: decompose work into tasks via `TaskCreate`. One task per logical unit (agent dispatch, phase, file group).
-2. **While working**: `TaskUpdate(status="in_progress")` when starting, `completed` when done. Add `owner` for delegated tasks.
-3. **Between steps**: `TaskList` to review progress, decide next action, catch forgotten work.
-4. **Enrich with metadata**: `TaskCreate(..., metadata={agent: "bilby", file: "src/main.rs", phase: "impl"})`
-5. **Sequence with dependencies**: `TaskUpdate(addBlockedBy=["1"])` for ordered work.
-
-
-#### Standalone vs Teams
-
-| Mode | When | How |
-|------|------|-----|
-| **Standalone** (Agent/Task) | Parallel independent work, no shared files | Fire-and-forget, each agent writes to a file |
-| **Team** (TeamCreate + SendMessage + Task tools) | Agents coordinate, share files, or avoid duplicate work | Shared task list, real-time messaging |
-
-Heuristic: if agents might step on each other's toes (editing same files, fixing same issues), use a team. Otherwise, standalone.
-
-#### Team Lifecycle
-
-1. `TeamCreate(team_name="<name>")` — creates team + shared task list
-2. Spawn teammates: `Agent(subagent_type="...", team_name="<name>", name="<agent-name>", ...)`
-3. Assign tasks: `TaskUpdate(owner=...)` — agents check `TaskList` to find available work
-4. Coordinate: `SendMessage(to="<name>", message="...")` — messages delivered automatically, no polling
-5. Shutdown: `SendMessage(to="<name>", message={type: "shutdown_request"})` to each teammate when done
-
-
-#### SendMessage Patterns
-
-- **Direct**: `SendMessage(to="agent-name", message="...")` — targeted coordination
-- **Broadcast**: `SendMessage(to="*", message="...")` — linear cost in team size, use sparingly
-- Use for: overlapping-work alerts, completion summaries, conflict flags
-
-#### Example: Team-Based Review
-
-```
-TeamCreate(team_name="review")
-# Spawn 3 review agents into team, each with different file scope
-# Each agent: TaskCreate for findings → claim via TaskUpdate(owner=...) → fix
-# Lead: TaskList to track progress → merge results → shutdown teammates
-```
-
-See `ci-dance` and `review-pr` skills for production team patterns.
-
-#### Rules
-
-- Spawn independent agents **in parallel** in a single message
-- **Model override**: Agent tool `model` param overrides frontmatter defaults. Use `model: "sonnet"` for routine tasks (docs, config, straightforward implementation). Use `model: "opus"` for deep analysis (security audits, architecture, complex debugging). Consult the active workflow skill's Model Selection section for per-phase guidance.
-- `run_in_background: true` for very large tasks
-
-### Agent Prompt Requirements
-
-Agents have NO conversation history. Every prompt MUST include:
-1. **Role/scope**: what to do, which files, focus area
-2. **File list**: explicit paths or globs
-3. **Output format**: structure, severity, where to write
-4. **Constraints**: what NOT to do
-5. **UX/DX context**: desired end-user/developer experience
-6. **Change visibility**: tell agents to check `git diff` AND `git status` (or provide explicit paths). Haiku agents miss changes with only `git diff HEAD`.
-7. For baseline comparisons: how to see what changed (`git diff`, `git show`)
-8. **Worktree base sync**: for `isolation: "worktree"` agents, include the resolved commit SHA (from `git rev-parse HEAD`), never a branch name or symbolic ref, and `git merge --ff-only <sha>` instruction as first action
-
-### MemCan Context Injection
-
-Before spawning, search MemCan (`memcan:recall`) and inject key findings into agent prompts.
-
-### Worktree Isolation
-
-ALL spawned agents MUST use `isolation: "worktree"` — no exceptions.
-
-**Pre-flight (blocking):** `git log @{upstream}..HEAD --oneline` — if unpushed commits exist OR no upstream is configured, STOP and push first (worktree agents fork from `origin`, not local branch).
-
-**Base commit injection:** Before spawning, capture the resolved commit SHA via `git rev-parse HEAD` — never use a branch name or symbolic ref (they resolve differently in worktrees). Include in every worktree agent's prompt: `"Your worktree may be behind local HEAD. As your FIRST action, run: git merge --ff-only <sha>"` — substitute the actual SHA. This works because worktrees share the object store.
-
-**Post-wave:** enumerate worktrees → verify commits → cherry-pick/merge into main → run tests → **push to remote** → clean up (`git worktree remove` + `prune`). Never remove worktrees with uncommitted/unmerged work. Always push after merging — worktree agents fork from `origin`, so unpushed merges cause stale-origin issues for subsequent waves.
-
-**Post-wave pitfalls:**
-- **Verify current branch** before cherry-picking — `git worktree remove` can leave you on the worktree's branch. Always `git branch --show-current` and `git checkout <your-branch>` if needed.
-- **Use absolute paths** with `git -C` — relative paths break if shell CWD drifts during the session.
-- **Delete stale worktree branches** after cherry-picking — worktree branches (`worktree-agent-xxx` + feature branches) accumulate fast. Clean with `git branch -D <worktree-branches>` after merging.
-
-**Anti-pattern:** committing locally without pushing, then launching worktree agents that need those changes — worktrees won't see them.
-
-### Scaling
-
-**Splitting:** For large tasks (50+ files), spawn multiple agents of same type with different file scopes split by package/module/layer.
-
-**Batching:** Merge small tasks so each agent gets ≥100 lines of work. Avoid spawning agents for tiny isolated changes. Respect specialization boundaries — don't merge frontend with backend, security with docs, or unrelated domains. Group by: same layer, same language, same agent type.
-
-### Output
-
-Standalone agents write to `<tmpdir>/<agent-name>-report.md` (session dir: `mktemp -d /tmp/claudius-XXXXXX`). Team agents use SendMessage. Each agent reports skills used; calculate redundancy ratio on overlap.
-
-**Candy tally**: When wrapping up a workflow, collect each agent's 🍬 count from their reports and present a summary — agent name, findings count, candy earned. The agent with the most findings wins bragging rights.
-
-### Recovery
-
-**Stuck agent:** rephrase and resend with `model: "opus"`. Second failure → shut down, reassign.
-
-**Stale diagnostics:** IDE `<new-diagnostics>` are async snapshots that may arrive after fixes. Verify with fresh build before acting — build output is source of truth.
-
-### Anti-Patterns
-
-1. Vague prompts — be explicit about files, focus, output format
-2. Single agent for large scope — split by file scope
-3. Forgetting agent skills — use correct `subagent_type` for preloaded skills
-4. No output location — always specify where standalone agents write
-5. Parallelizing tightly coupled work — use single opus agent sequentially for cross-file dependencies
-6. Trusting stale diagnostics — verify with fresh build
-7. Spawning agents for tiny tasks — batch small tasks (≥100 lines per agent) within same specialization
-8. Auto-deleting data on errors — NEVER delete databases, wipe volumes, or destroy data without explicit user confirmation (see CLAUDE.md Safety section)
-9. Not verifying branch context after worktree cleanup — `git worktree remove` can change checked-out branch, causing cherry-picks into wrong branch
