Trinity — Multi-Model Orchestration

Dispatch tasks to external LLM providers via background sub-agents. Providers are auto-discovered from config + agent files. Sessions stored in .claude/trinity.json. Health monitoring via output file heartbeat.

Startup Check (run once per session before first dispatch)

# 0. Refuse nested dispatch when Trinity is running as a claude-code provider
if [ "${TRINITY_DISABLE_DISPATCH:-}" = "1" ]; then
  echo "trinity: Nested Trinity dispatch is disabled in this Claude Code process (set by the claude-code provider wrapper)."
  exit 1
fi

# 1. Verify python3 is available
command -v python3 >/dev/null 2>&1 || {
  echo "trinity: python3 not found. Install: brew install python3"
  # abort dispatch
}

# 2. Verify scripts are installed and up to date
SCRIPTS_VERSION=$(python3 ~/.claude/skills/trinity/scripts/session.py --version 2>/dev/null)
REQUIRED_VERSION="3.3.0"
if [ "$SCRIPTS_VERSION" != "$REQUIRED_VERSION" ]; then
  echo "trinity: scripts not installed or outdated (found: ${SCRIPTS_VERSION:-none}, need: $REQUIRED_VERSION)"
  echo "Run: make install (from trinity/ repo) or: cp -r trinity/scripts/. ~/.claude/skills/trinity/scripts/"
  # abort dispatch
fi

If scripts pass the version check, proceed normally.

Session Transcript Paths

Resolve a provider's on-disk JSONL transcript path for a stored session pointer (token-efficiency audits, replay debugging).

trinity session-path <provider>[:<instance>] [--project <dir>]

The command reads <project>/.claude/trinity.json, looks up the pointer for the given key, dispatches to a per-provider resolver, and prints the absolute JSONL path on stdout. Path-only — transcript content is never read or surfaced. The :default suffix is stripped at lookup (glm:default is equivalent to glm); other suffixes (e.g. glm:experimental) pass through verbatim.

Provider	Transcript root
glm	~/.factory/sessions/<encoded-project-path>/<session-id>.jsonl
codex	~/.codex/sessions/<YYYY>/<MM>/<DD>/...<session-id>.jsonl (index-first via ~/.codex/session_index.jsonl; broad-glob fallback)
claude-code	~/.claude-trinity-claude-code/projects/<PROJECT_SLUG>/<session-id>.jsonl
deepseek	~/.claude-deepseek/projects/<PROJECT_SLUG>/<session-id>.jsonl
openrouter	~/.claude-openrouter/projects/<PROJECT_SLUG>/<session-id>.jsonl
gemini	not yet supported (exits 3 with explicit deferral message)

Path encoding: absolute project path with / replaced by -. All resolvers KEEP the leading dash — glm (matches ~/.factory/sessions/-Users-frank-...) and the claude-CLI wrappers (claude-code / deepseek / openrouter, matches PROJECT_SLUG=$(echo "$PROJECT_DIR" | sed 's|/|-|g') per providers/<name>.md and the claude CLI's ~/.claude-*/projects/-Users-frank-... layout).

The claude-CLI wrappers themselves are installed at ~/.claude/skills/trinity/bin/<name> (e.g. ~/.claude/skills/trinity/bin/claude-code, ~/.claude/skills/trinity/bin/deepseek, ~/.claude/skills/trinity/bin/openrouter) — these are the CLI binaries. Their per-wrapper transcript stores listed above are separate from the wrapper bin directory.

Exit codes:

• 0 — path printed; file exists on disk.
• 2 — no session pointer for the provided key.
• 3 — provider unsupported, transcript file missing, malformed session_id, or codex multi-glob residual (>1 match).

Provider Discovery

On every dispatch, resolve available providers and presets:

1. Load ~/.claude/trinity.json → providers, presets, and preset_aliases (global)
2. Load .claude/trinity.json → project overlay; project entries win on conflict
3. Verify each provider has a matching agent file: ~/.claude/agents/trinity-<name>.md or .claude/agents/trinity-<name>.md

A provider is usable only when it has both a config entry AND an agent file.

• Config entry but no agent file → "⚠️ unregistered (missing agent file)" in /trinity status; dispatch blocked
• Agent file but no config entry → "⚠️ unregistered (missing config)" in /trinity status; dispatch blocked
• Neither → not listed

Config Overlay

Merge semantics:

• providers: merged by key; project entry wins on same key. Global providers not overridden remain available.
• defaults: shallow merge; project value overrides global for each key. Keys absent in project inherit from global.
• presets: merged by key; project preset replaces the whole global preset object with that name.
• preset_aliases: merged by key; project alias wins on same alias.
• sessions: project-only; never in global config.

Global ~/.claude/trinity.json:

{
  "providers": {
    "glm":     { "cli": "droid exec --auto medium --model custom:GLM-5.2", "installed": true },
    "minimax": { "cli": "droid exec --auto medium --model custom:MiniMax-M3", "installed": true },
    "codex":   { "cli": "codex exec --skip-git-repo-check -m gpt-5.5", "installed": true },
    "gemini":  { "cli": "gemini -p",                        "installed": true }
  },
  "defaults": {
    "heartbeat_interval": 120,
    "timeout": { "tdd": 600, "review": 360, "general": 1200 }
  }
}

Project .claude/trinity.json:

{
  "providers": {
    "local": { "cli": "ollama run llama3", "installed": true }
  },
  "sessions": {
    "glm:auth": {
      "session_id": "...",
      "output_file": "/private/tmp/claude-501/.../tasks/<agentId>.output",
      "start_time": "2026-03-21T01:00:00",
      "task_type": "tdd",
      "last_line_count": null,
      "last_heartbeat": null,
      "stopped": false,
      "last_used": "2026-03-21T01:00:00",
      "task_summary": "JWT auth module"
    }
  }
}

Field notes:

• output_file: captured from Agent tool response text at dispatch (line matching output_file: /...). Cleared when task-notification arrives.
• last_line_count: null = never checked; integer = JSONL line count at last heartbeat.
• last_heartbeat: ISO timestamp of last check. Written back immediately after every heartbeat.
• stopped: true when stopped. Distinguishes ⏸️ stopped from ❌ failed.
• task_type: one of tdd, review, prp, general. Used for timeout thresholds.

Review Presets

Preset dispatch expands one keyword into a configured provider set:

Preset	Required providers	Optional providers
review	glm, gemini, deepseek	codex, claude-code
fast-review	glm, deepseek	none
deep-review	glm, gemini, deepseek	codex, claude-code

Aliases r, fr, and dr resolve to review, fast-review, and deep-review. Optional providers are used only when discovery marks them usable; otherwise show a warning and continue with the required providers.

Execution Rules

Dispatch mode (preset or provider detected)

Parse dispatch in this order:

1. Built-in subcommands: status, clear, plan, heartbeat, install, help.
2. Preset or alias name: expand providers and dispatch the same task to each.
3. Provider syntax: provider, provider:instance, or provider*N.

If a token is both a provider and a preset/alias, fail with an ambiguity error instead of guessing.

For EACH (provider, task) pair in the arguments:

1. Parse — extract base provider and optional instance name

   • glm → base=glm, instance=none (key: "glm")
   • glm:auth → base=glm, instance=auth (key: "glm:auth")
   • glm*2 → spawn 2 agents: key "glm:" each

2. Resolve providers — run provider discovery (see §Provider Discovery)

3. Validate — verify provider is usable (has both config entry and agent file)

   • If not usable: report error with reason ("missing agent file" / "missing config"), do NOT spawn

4. Spawn — for each validated (provider, task):

   Agent(
     subagent_type="general-purpose",
     description="{PROVIDER}: {short task description}",
     name="{PROVIDER-INSTANCE}",
     run_in_background=true,
     prompt="""
     You are the trinity-{base} worker agent.
     Read your instructions from ~/.claude/agents/trinity-{base}.md first.
     (Or from .claude/agents/trinity-{base}.md if present in the project.)
   
     Then execute this task:
   
     - Provider instance: {key}
     - Project dir: {cwd}
     - Task: {task}
     """
   )
   

5. Capture output_file — from the Agent tool response text, extract the line matching output_file: /.... Record dispatch metadata in .claude/trinity.json under sessions.<key>:

   {
     "session_id": null,
     "output_file": "<captured path>",
     "start_time": "<ISO now>",
     "task_type": "<inferred: tdd|review|prp|general>",
     "last_line_count": null,
     "last_heartbeat": null,
     "stopped": false,
     "last_used": "<ISO now>",
     "task_summary": "<short task description>"
   }
   

   Infer task_type from task keywords: "review"/"审查" → review; "tdd"/"test"/"测试" → tdd; "prp"/"proposal" → prp; otherwise → general.

6. Confirm — reply with a brief launch summary:

   Dispatched:
   - GLM:auth → "实现认证模块" (background)
   - Codex → "review auth 代码" (background)
   

7. On completion — when task-notification arrives, present the agent's summary to the user, then clear output_file, last_line_count, last_heartbeat from that session entry (keep session_id for future resume).

Proactive progress updates (always active)

On every user message while any agent has output_file set and stopped: false:

Load heartbeat_interval from merged config (default: 120s). For each such agent, check if last_heartbeat is null OR ≥heartbeat_interval seconds have elapsed. If so, run a heartbeat check and prepend results to the response.

This is message-triggered with throttling — not a background timer.

Also check timeout thresholds (§C) on every proactive check.

Heartbeat mode (/trinity heartbeat [<instance>])

On-demand liveness check. If <instance> given, check only that entry; otherwise check all entries with output_file set and stopped: false.

For each agent to check:

1. Read output file:

   wc -l <output_file>           # total JSONL line count
   tail -10 <output_file>        # last 10 lines for parsing
   

2. Handle missing file:

   • File absent, elapsed < 30s → "🟡 starting"
   • File absent, elapsed ≥ 30s → "❌ failed to start"
   • File present but empty → "🟡 starting (0 lines)"

3. Parse last activity from tail output (skip malformed/partial lines):

   • Find last line with type: "assistant" → extract text or tool name + input summary
   • Find last line with type: "user" and tool_result → extract result preview

4. Liveness signal:

   • current_lines > last_line_count (or last_line_count was null) → "🔄 alive (+N lines)"
   • current_lines == last_line_count and elapsed since dispatch > 60s → "⚠️ possibly stalled (no new lines)"
   • Zero delta can be a false positive during long reasoning — report "possibly stalled", not "stuck"

5. Update .claude/trinity.json: write last_line_count = current_lines, last_heartbeat = now atomically (fcntl.flock on the project sessions file).

6. Display:

   GLM:auth    🔄 alive    +23 lines   [4m 12s]   Bash: pytest tests/test_auth.py -v
   Codex       ⚠️ possibly stalled  +0 lines  [6m 05s]   Read: auth.py (line 45-80)
   Gemini      ✅ done      —          [2m 10s]   —
   

Timeout alerts (§C)

Load thresholds from merged config defaults.timeout. Built-in defaults:

task_type	warn_at	max_at
tdd	10 min	15 min
review	6 min	10 min
prp	5 min	8 min
general	10 min	20 min

On each proactive check or heartbeat, compare now - start_time against thresholds:

• At warn_at: ⚠️ GLM:auth review 已跑 6 分钟（预期 <4 分钟）— 最后活动: Read auth.py (2 分钟前)
• At max_at: 🚨 GLM:auth review 已跑 10 分钟（已超时）— 建议: /trinity clear glm:auth 或继续等待

Status mode (/trinity status)

Run provider discovery. Display two sections:

Registered providers:

**Configured presets:**

Preset	Providers	Optional	Aliases
review	glm, gemini, deepseek	codex, claude-code	r
fast-review	glm, deepseek		fr
deep-review	glm, gemini, deepseek	codex, claude-code	dr

| Provider | Status    | CLI                              |
|----------|-----------|----------------------------------|
| glm      | ✅ usable  | droid exec --auto medium --model custom:GLM-5.2 |
| minimax  | ✅ usable  | droid exec --auto medium --model custom:MiniMax-M3 |
| codex    | ✅ usable  | codex exec --skip-git-repo-check -m gpt-5.5 |
| gemini   | ⚠️ missing | (agent file not found)           |

Active sessions (run heartbeat check for each with output_file set):

| Provider | State         | Duration | Last Activity            | Task            |
|----------|---------------|----------|--------------------------|-----------------|
| glm:auth | 🔄 alive +12  | 4m 12s   | Bash: pytest -v          | TDD auth module |
| codex    | ⚠️ stalled +0  | 6m 05s   | Read: auth.py:45         | Review auth     |

If no sessions, show "No active sessions."

Clear mode (/trinity clear)

Synchronous. Operates on .claude/trinity.json sessions key.

• /trinity clear glm:auth → delete "glm:auth" entry, confirm
• /trinity clear glm → delete "glm" and all "glm:*" entries, confirm
• /trinity clear all → write {} to sessions key, confirm

Parallel mode (/trinity glm*2 "task")

Parse glm*2 as: spawn 2 agents with base=glm. Auto-generate instance keys:

import uuid
key = f"glm:{uuid.uuid4().hex[:6]}"

Each agent gets its own instance key and independent session.

Install mode (/trinity install <provider>)

Flow (atomic — all steps must succeed or roll back):

1. Check which <provider-cli> → already in PATH → skip to step 4
2. Try Homebrew: brew search <provider> → formula found → brew install <formula> → on failure fall through
3. Try npm: npm install -g <npm-package> → on failure try pip (glm and minimax — both droid-backed) → on all failures: report ❌ + manual install link, abort
4. Copy agent template: trinity/providers/<provider>.md → ~/.claude/agents/trinity-<provider>.md
5. Register in ~/.claude/trinity.json under providers.<provider> (atomic write: read → merge → write)
6. Smoke test (Bash timeout 30s): <cli> "Reply with exactly: trinity-ok" → verify response contains trinity-ok
7. On any failure in steps 4–6: delete ~/.claude/agents/trinity-<provider>.md if created, remove providers.<provider> from config if written, report ❌ with specific step that failed
8. Report ✅ <provider> installed and verified

Built-in install specs:

Provider	brew	npm	pip	Prerequisite
codex	brew install codex*	npm i -g @openai/codex	—	OpenAI account
gemini	brew install gemini-cli*	npm i -g @google/gemini-cli	—	Google account
glm	—	—	pip install factory-droid	Factory AI account
minimax	—	—	pip install factory-droid	Factory AI account

*Brew formula name verified at runtime via brew search; if no result or install fails, fall through to npm/pip.

Plan mode (/trinity plan)

Two input modes:

Manual assignment — user specifies providers and tasks:

/trinity plan glm:auth "实现认证" glm:order "实现订单" codex "review 全部代码"

Auto-decompose — single string description (no provider specified):

/trinity plan "实现电商系统，需要认证、订单、支付三个模块"

Auto-decompose algorithm:

1. Analyze the description and identify independent sub-tasks
2. Assign each sub-task to a provider based on task type (coding → glm, review → codex/gemini, analysis → any)
3. Identify dependencies (review waits for coding; independent tasks run in parallel)
4. Draw ASCII sequence diagram showing assignment and dependency order
5. Ask user to confirm ([Execute] / [Modify] / [Cancel]) via AskUserQuestion
6. On Execute: dispatch parallel tasks first, then sequential tasks after notifications arrive

Sequence diagram format:

User    Claude    GLM:auth   GLM:order   Codex
 │        │          │          │          │

 │◀─done──│          │          │          │

Help mode (/trinity help)

Synchronous. Read ~/.claude/skills/trinity/README.md and output its full content.

Error Handling

• Unknown provider → run provider discovery, report "Unknown provider: xxx. Available: . Run /trinity install xxx to add it."
• Usable providers list empty → "No providers registered. Run /trinity install <provider> to get started."
• Missing agent file → "Provider xxx has no agent file. Run /trinity install xxx to set it up."
• Missing config entry → "Provider xxx has no config entry. Run /trinity install xxx to register it."
• Empty task → "Task cannot be empty"
• .claude/ doesn't exist → create it with empty trinity.json
• trinity.json doesn't exist → create with {} before first write
• output_file capture fails → log warning, proceed without monitoring for that agent

Reserved Words

status, clear, plan, heartbeat, install, and help are subcommands, NOT provider or preset names. Preset/provider collisions are invalid and must be reported as ambiguous. Alias names must not collide with subcommands, providers, or preset names.
