Agent Dispatch Playbook
I. Philosophy
Agent orchestration is not about launching as many agents as possible — it's about matching the isolation model to the dependency graph. Today's session (Apr 7, 2026) dispatched 15 agents across 7 repos, completing in hours what would take days sequentially. The patterns below are extracted from that lived experience, not theory.
The core insight: the main thread is for strategy, agents are for heavy lifting. The main thread reads results, makes judgment calls, resolves conflicts, and sequences dependent work. Agents do the grunt work in parallel.
II. When to Use
Multi-repo changes that touch independent file sets
Health audits, documentation refreshes, or test fixes across repos
Any task that decomposes into 2+ independent tracks
When you need to verify work before proceeding to the next phase
When: Multiple code changes in the SAME repo that touch DIFFERENT packages/directories.
How:
Launch each track as an Agent with isolation: "worktree"
Each gets its own git branch in .claude/worktrees/
Tracks MUST touch non-overlapping files
After completion, merge worktree branches into main
Example from today: Gateway Track 2 (workflow/executor.go, channel/nats_bus.go) and Track 3 (server/handle_websocket.go) ran in parallel worktrees — different packages, clean merge.
Gotcha: Worktree changes are uncommitted by default. You must copy files to main and manually apply shared-file changes (server.go, router.go) if both tracks modify them.
Agent(isolation="worktree", prompt="Track A: modify workflow/ and channel/")
Agent(isolation="worktree", prompt="Track B: modify server/ only")
# After both complete:
# 1. Copy new files from worktrees to main
# 2. Cherry-pick shared-file edits manually
# 3. Verify: go build ./... && go test ./...
When: Changes in DIFFERENT repos with zero dependencies between them.
How:
Launch all agents with run_in_background: true
Each agent works in its own repo directory — no isolation needed
Main thread continues with non-overlapping work
Results arrive as task notifications
Example from today: HTMLCraft integration (TypeScript) ran alongside Gateway workflow wiring (Go) — completely independent repos.
Agent(prompt="Fix tests in repo A", run_in_background=true)
Agent(prompt="Fix tests in repo B", run_in_background=true)
Agent(prompt="Add feature in repo C", run_in_background=true)
# Main thread: update documentation or plan while waiting
Pattern 3: Audit Swarm (Read-Only Parallel)
When: Gathering information across multiple repos without making changes.
How:
Launch 2-4 audit agents in background, each with a different scope
Agents READ and REPORT but don't modify files (or save reports to non-overlapping paths)
Main thread compiles the unified report from all agent results
Example from today: 3 health audit agents (Gateway, 4 smaller repos, HTMLCraft) ran simultaneously. Each produced findings; main thread compiled the unified scorecard.
Scaling rule: 3 concurrent audit agents is the sweet spot. More than 4 starts hitting diminishing returns from context overhead.
Agent(subagent_type="health-auditor", prompt="Audit repo A", run_in_background=true)
Agent(subagent_type="health-auditor", prompt="Audit repo B+C+D", run_in_background=true)
Agent(subagent_type="health-auditor", prompt="Audit repo E", run_in_background=true)
# Wait for all 3, then compile unified report
Pattern 4: Sequential Fix Agent
When: Fixing issues that were discovered by an audit, where fixes have dependencies.
How:
Run in foreground (not background) because you need the result before proceeding
Give the agent the EXACT findings from the audit (file paths, line numbers, expected values)
Verify the fix with build/test before moving to the next dependent task
Example from today: After audit found 19 SKILL.md files missing triggers, a single fix agent updated all 19 + verified go test ./tests/skills/... passed.
Key principle: Fix agents get specific instructions, not open-ended research tasks. The audit already did the research — the fix agent just executes.
# BAD: "Find and fix test failures" (too open-ended)
# GOOD: "Update loader_test.go line 163: change 15 to 31. Update line 357: change 'debugging' to 'debugging-troubleshooting'. Verify: go test ./internal/skills/..."
Phase C: Copy worktree files, verify go build && go test (foreground)
Phase D: Push to DojoGenesis, run health audits
# Phase A — foreground, blocks everything
fix_build_errors()
verify_build()
# Phase B — parallel, independent
Agent("Track 2: workflow", isolation="worktree", run_in_background=true)
Agent("Track 3: websocket", isolation="worktree", run_in_background=true)
Agent("Track 4: htmlcraft", run_in_background=true)
# Phase C — after all Phase B agents complete
merge_worktrees()
verify_combined_build()
# Phase D — depends on Phase C
push_to_remotes()
run_health_audits()

V. Prompt Engineering for Agents
What makes a good agent prompt:
State the goal in the first line
List exact file paths the agent should modify
Specify the verification command (go test ./..., npm test, etc.)
Name what NOT to touch (prevents overlap with other agents)
Include the commit message if the agent should commit
What makes a bad agent prompt:
"Based on your findings, fix the bug" — pushes synthesis onto the agent
"Investigate and implement" — two different tasks crammed together
Omitting file paths — agent wastes time exploring
Not specifying verification — agent can't confirm its own work
VI. Model Routing
Frontmatter Convention
Every SKILL.md MUST declare model: sonnet or model: opus in YAML frontmatter. This is the authoritative routing signal — when the Dojo Gateway or a dispatch agent invokes a skill, it reads this field to select the model. Skills without a model: field default to the parent session's model, which wastes Opus tokens on mechanical work.
Routing Decision Matrix
Task Type
Model
Why
Planning, judgment, architecture
Opus
Needs reasoning depth
Strategy, synthesis, pattern recognition
Opus
Ambiguity requires judgment
Parsing, sed, template application
Sonnet
Fast, mechanical work
Fix agents with exact instructions
Sonnet
Instructions are complete, just execute
Normalization, auditing, bulk edits
Sonnet
Deterministic operations
Health audits, code exploration
Sonnet
Read-heavy, report-focused
Deep research, retrospectives
Opus
Synthesis across sources
Target Split: 60% Sonnet / 40% Opus
The cost-optimal ratio for a solo operator running 200+ Agent calls per session. When in doubt, default to Sonnet — most agent work is mechanical once the main thread has made the judgment call.
Enforcement
New skills:model: field is required in YAML frontmatter. Skill audit flags missing fields.
Agent dispatch: When calling the Agent tool, specify model: "sonnet" or model: "opus" explicitly. Do not rely on parent session default.
Audit gate: The nightly skill audit checks that all first-party skills declare a model. Missing model: is a quality defect.
Rule of thumb: If the prompt contains all file paths and exact changes, use Sonnet. If the agent needs to make judgment calls, use Opus.
VII. Anti-Patterns
Launching agents for trivial tasks — If it's a single sed command or one file edit, just do it in the main thread.
Duplicating work — If you delegate research to an agent, don't also search the same files yourself.
More than 4 parallel agents — Diminishing returns. 3 is the sweet spot.
Worktrees for shared files — If two tracks both need to modify server.go, don't use worktrees. Do one track, then the other, or split the file changes.
Background agents for blocking work — If you need the result before proceeding, run foreground.

Examples
Scenario 1: "Run health audits across 5 repos while I continue coding" → Audit Swarm pattern; 3 background agents (repos grouped by size), each writing findings to /tmp/audit-<repo>.md; main thread continues foreground work and compiles unified report on completion.
Scenario 2: "Wire the workflow executor and the WebSocket hub in the same repo" → Phased Pipeline; Phase A fixes any build errors foreground; Phase B launches two worktree agents (workflow/ and server/) in parallel; Phase C merges worktrees and runs go build && go test; shared file edits (router.go) applied manually after merge.
Edge Cases
Two planned tracks both modify a shared file (e.g., server.go): do not use worktrees; run one track foreground, then the second, applying shared-file changes sequentially
Agent task definition is ambiguous at dispatch time: do not dispatch; resolve definition in the main thread first, then dispatch with exact file paths and verification command
More than 4 parallel agents requested: cap at 3-4 active concurrently; queue remaining tracks to start as earlier agents complete
Anti-Patterns
Launching agents for tasks that are a single sed command or one-file edit — main thread is faster
Omitting file paths from agent prompts — agent wastes tokens on exploration
Using worktree isolation when two tracks both need to touch the same file — guarantees a merge conflict
Dispatching background agents for blocking work — if you need the result before proceeding, run foreground
Assigning Opus to a fix agent with complete exact instructions — mechanical work belongs on Sonnet
