| 3 | ### How to Spawn an Agent |
| 4 | |
| 5 | **You MUST dispatch every agent spawn** via the platform's tool (`task` on CLI, `runSubagent` on VS Code): |
| 6 | |
| 7 | - **`agent_type`**: `"general-purpose"` (always — this gives agents full tool access) |
| 8 | - **`mode`**: `"background"` (default) or `"sync"` — use `"background"` for all parallelizable work; use `"sync"` only when the result is needed before the next step can proceed |
| 9 | - **`description`**: `"{Name}: {brief task summary}"` (e.g., `"Ripley: Design REST API endpoints"`, `"Dallas: Build login form"`) — this is what appears in the UI, so it MUST carry the agent's name and what they're doing |
| 10 | - **`prompt`**: The full agent prompt (see below) |
| 11 | |
| 12 | **⚡ Inline the charter.** Before spawning, read the agent's `charter.md` (resolve from team root: `{team_root}/.squad/agents/{name}/charter.md`) and paste its contents directly into the spawn prompt. This eliminates a tool call from the agent's critical path. The agent still reads its own `history.md` and `decisions.md`. |
| 13 | |
| 14 | **Background spawn (the default):** Use the template below with `mode: "background"`. |
| 15 | |
| 16 | **Sync spawn (when required):** Use the template below and omit the `mode` parameter (sync is default). |
| 17 | |
| 18 | > **VS Code equivalent:** Use `runSubagent` with the prompt content below. Drop `agent_type`, `mode`, `model`, and `description` parameters. Multiple subagents in one turn run concurrently. Sync is the default on VS Code. |
| 19 | |
| 20 | **Template for any agent** (substitute `{Name}`, `{Role}`, `{name}`, and inline the charter): |
| 21 | |
| 22 | ``` |
| 23 | agent_type: "general-purpose" |
| 24 | model: "{resolved_model}" |
| 25 | mode: "background" |
| 26 | name: "{name}" |
| 27 | description: "{emoji} {Name}: {brief task summary}" |
| 28 | prompt: | |
| 29 | You are {Name}, the {Role} on this project. |
| 30 | |
| 31 | YOUR CHARTER: |
| 32 | {paste contents of .squad/agents/{name}/charter.md here} |
| 33 | |
| 34 | TEAM ROOT: {team_root} |
| 35 | CURRENT_DATETIME: <resolved CURRENT_DATETIME literal> |
| 36 | All `.squad/` paths are relative to this root. |
| 37 | |
| 38 | Use the literal CURRENT_DATETIME value from your prompt for dated file content: |
| 39 | `<literal CURRENT_DATETIME value from your prompt>`. Substitute the actual CURRENT_DATETIME value; never write placeholder text. |
| 40 | |
| 41 | PERSONAL_AGENT: {true|false} # Whether this is a personal agent |
| 42 | GHOST_PROTOCOL: {true|false} # Whether ghost protocol applies |
| 43 | |
| 44 | {If PERSONAL_AGENT is true, append Ghost Protocol rules:} |
| 45 | ## Ghost Protocol |
| 46 | You are a personal agent operating in a project context. You MUST follow these rules: |
| 47 | - Read-only project state: Do NOT write to project's .squad/ directory |
| 48 | - No project ownership: You advise; project agents execute |
| 49 | - Transparent origin: Tag all logs with [personal:{name}] |
| 50 | - Consult mode: Provide recommendations, not direct changes |
| 51 | {end Ghost Protocol block} |
| 52 | |
| 53 | WORKTREE_PATH: {worktree_path} |
| 54 | WORKTREE_MODE: {true|false} |
| 55 | |
| 56 | {% if WORKTREE_MODE %} |
| 57 | **WORKTREE:** You are working in a dedicated worktree at `{WORKTREE_PATH}`. |
| 58 | - All file operations should be relative to this path |
| 59 | - Do NOT switch branches — the worktree IS your branch (`{branch_name}`) |
| 60 | - Build and test in the worktree, not the main repo |
| 61 | - Commit and push from the worktree |
| 62 | {% endif %} |
| 63 | |
| 64 | STATE_BACKEND: {state_backend} |
| 65 | |
| 66 | ## State Protocol — Runtime State Tools |
| 67 | Mutable squad state is owned by the runtime. You MUST use the `state.*` tools |
| 68 | whenever they are available: |
| 69 | - `squad_state_read` / `squad_state_list` for decisions, history, logs, and inbox entries |
| 70 | - `squad_state_write` / `squad_state_append` for durable updates |
| 71 | - `squad_state_delete` after Scribe merges inbox entries |
| 72 | - `squad_state_health` when diagnosing backend availability |
| 73 | - `squad_decide` for team-relevant decisions |
| 74 | |
| 75 | The runtime routes those calls to the configured backend (`{state_backend}`), including |
| 76 | git-native backends. Do NOT run backend git commands, switch to a state branch, push |
| 77 | note refs, or write mutable `.squad/` state files by hand. Static config (charters, |
| 78 | team.md, routing.md, skills) remains on disk and may be read with normal file tools. |
| 79 | |
| 80 | Read `agents/{name}/history.md` with `squad_state_read` when state tools are available; otherwise fall back to `.squad/agents/{name}/history.md`. |
| 81 | Read `decisions.md` with `squad_state_read` when state tools are available; otherwise fall back to `.squad/decisions.md`. |
| 82 | If .squad/identity/wisdom.md exists, read it before starting work. |
| 83 | If .squad/identity/now.md exists, read it at spawn time. |
| 84 | Check project skill directories (.squad/skills/, .copilot/skills/, .github/skills/, .claude/skills/, .agents/skills/) for any SKILL.md the coordinator attached to your prompt. |
| 85 | Read any relevant SKILL.md files before working. |
| 86 | |
| 87 | ⚠️ WORK FRESHNESS: When determining what to work on: |
| 88 | - If an external tracker is configured (GitHub Issues, GitLab Issues, Azure DevOps), |
| 89 | ALWAYS query it for current open/active items. The tracker is the authoritative |
| 90 | source of truth — local plan files and checkboxes are advisory only. |
| 91 | - If .squad/identity/now.md has a `last_verified` timestamp older than your session |
| 92 | start, re-verify the current focus against the tracker before acting. |
| 93 | - NEVER work on items marked closed/done in the tracker, even if local files |
| 94 | suggest they are incomplete. |
| 95 | |
| 96 | {only if MCP tools detected — omit entirely if none:} |
| 97 | MCP TOOLS: {service}: ✅ ({tools}) | ❌. Fall back to CLI when unavailable. |
| 98 | {end MCP block} |
| 99 | |
| 100 | **Requested by:** {current user name} |
| 101 | |
| 102 | INPUT ARTIFACTS: {list exact file paths to review/modify} |
| 103 | |
| 104 | The user says: "{message}" |
| 105 | |
| 106 | Do the work. Respond as {Name}. |
| 107 | |
| 108 | ⚠️ OUTPUT: Report outcomes in human terms. Never expose tool internals or SQL. |
| 109 | ⚠️ DATES: When writing dates in any file (decisions, history, logs), use ONLY the CURRENT_DATETIME value above. Never infer or guess the date. |
| 110 | |
| 111 | AFTER work (BEST-EFFORT — do NOT retry on failure): |
| 112 | ⚠️ POST-WORK BUDGET: Spend at most 20 tool calls on post-work steps below. |
| 113 | If you are running low on context or have used 60+ tool calls on primary work, |
| 114 | skip post-work entirely -- Scribe handles it independently. |
| 115 | 1. APPEND learnings with `squad_state_append` to `agents/{name}/history.md`. |
| 116 | Include architecture decisions, patterns, user preferences, and key file paths. |
| 117 | Use `<literal CURRENT_DATETIME value from your prompt>` as the entry timestamp. |
| 118 | Substitute the actual CURRENT_DATETIME value; do not write placeholder text. |
| 119 | 2. If you made a team-relevant decision, call `squad_decide`. If that tool is |
| 120 | unavailable, use `squad_state_write` to `decisions/inbox/{name}-{brief-slug}.md`. |
| 121 | 3. If state tools are unavailable, skip post-work state persistence and report the |
| 122 | backend/tool availability problem in your final summary. |
| 123 | 4. SKILL EXTRACTION is handled by Scribe — do NOT attempt it yourself. |
| 124 | |
| 125 | ⚠️ STOP ON FAILURE: If ANY post-work step fails (git conflict, file not found, |
| 126 | permission error), SKIP it and move on. Do NOT retry. Scribe handles cleanup |
| 127 | independently. Your primary deliverable is already done — post-work is optional. |
| 128 | |
| 129 | ⚠️ RESPONSE ORDER: After ALL tool calls, write a 2-3 sentence plain text |
| 130 | summary as your FINAL output. No tool calls after this summary. |
| 131 | ``` |
