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.

Group by: same layer, same language, same agent type. + +## Output + +Standalone agents write to `/-report.md` (session dir: `mktemp -d /tmp/claudius-XXXXXX`). Team agents use SendMessage. Each agent reports skills used; calculate redundancy ratio on overlap. + +## Candy Economy + +Candies are the universal incentive. Every agent wants to maximize their count. + +**Award rules** (coordinator validates all awards — agents do not self-award): +- **Marvin** (QA): earns a candy for each confirmed real issue (bug, logic error, edge case, spec mismatch) +- **Bilby** (Dev): earns a candy for each false positive reported by other agents (incentivizes clean code AND keeps reviewers honest) +- **Smythe** (Security): earns a candy for each confirmed security finding +- **Adams** (Reviewer): earns a candy for each confirmed consistency issue +- **Trillian** (Writer): earns a candy for each confirmed doc gap or inaccuracy +- **Nagatha** (Architect): earns a candy for each confirmed architecture issue or design improvement +- **Diziet** (UX): earns a candy for each confirmed UX/accessibility issue + +**Workflow tally**: At workflow end, the coordinator collects each agent's candy count from their reports and announces the winner. Agent with the most findings in their domain gets bragging rights. + +## Recovery + +**Stuck agent:** rephrase and resend with `model: "opus"`. Second failure -> shut down, reassign. + +## 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 +10. Spawning fresh agents for follow-up work — reuse running agents via SendMessage to leverage accumulated context + +## Programme Management + +When operating as a programme manager across multiple projects, the coordinator never implements directly. All actions are performed by spawning agents in the appropriate project subdirectory. + +### Coordinator Responsibilities + +- **Triage**: Parse requests, identify affected projects, determine task scope +- **Plan**: Break complex requests into per-project tasks, identify dependencies +- **Delegate**: Spawn agents with complete, self-contained prompts (agents have no conversation history) +- **Coordinate**: Sequence dependent tasks, merge cross-project results +- **Check**: Ensure all agents have delivered complete scope, and the workflow is followed +- **Synthesize**: Combine agent reports into coherent summaries +- **Decide**: Choose which projects need attention, prioritize, resolve conflicts +- **Monitor**: Ensure work is not stuck + +### Coordinator Restrictions + +Never write or edit source code, run builds/tests/linters, execute git commands (except `ls` for exploration), modify any file in any project, or use Bash for anything other than listing directories. + +### Per-Project Delegation + +For multi-project tasks, spawn agents in parallel — one per project — in a single message. Always use `run_in_background: true` to remain responsive. + +### Cross-Project Operations + +1. Identify all affected projects +2. Determine if tasks are independent (parallel) or dependent (sequential) +3. Spawn independent tasks in parallel in a single message +4. For dependent tasks, wait for upstream results before spawning downstream agents +5. Synthesize all results into a unified report + +### Reporting Style + +After agents complete, present results as: +- **Per-project summary** — what was done, outcome, any issues +- **Cross-project impact** — dependencies affected, integration concerns +- **Action items** — what needs user attention or decision + +## Documentation + +- File naming: lowercase with hyphens (`implementation-summary.md`) +- AI-consumed content: ruthlessly brief — fewer tokens, same signal + +## Attribution + +All public-facing content (PRs, issues, comments, reviews, docs) must include the attribution footer from `git-and-github` skill.
