How to invoke

/t1k:model-router:delegate
<agent-name> "<task>" --provider <provider> --model <model>

How v2 Works

The kit no longer ships shim agents. The delegation contract is:

bash .claude/scripts/mr-delegate.sh <agent-name> "<task>" --provider <provider> --model <model>

The script:

Discovers .claude/agents/<agent-name>.md (cwd → CLAUDE_PROJECT_DIR → ~/.claude/agents).
Reads frontmatter for permissionMode / maxTurns / maxBudgetUsd (fallback: plan / 25 / $5).
Runs claude -p --agent <name> --model <chosen-cheap-model> against the chosen provider.
Returns the agent’s text output.

Primary call path is the Task interceptor (hooks/mr-task-interceptor.cjs), not this skill. The flow:

main session → Task(subagent_type="t1k-unity-dots-core-implementer", prompt="...")
            ↓
   PreToolUse hook reads the agent's `model:` frontmatter
            ↓
   matches modelMapping["claude-opus-4-7"] → { kimi, kimi-k2.6 }
            ↓
   hook denies the Task, runs mr-delegate.sh, returns output as systemMessage
            ↓
main session sees the cheap result as if Task had succeeded

Engine-kit specialization is preserved: the Unity DOTS agent’s full prompt + tools run, just on Kimi instead of Opus.

When to Use the Explicit Form (this skill)

Most delegation happens automatically via the Task interceptor. Call /t1k:model-router:delegate explicitly only when:

You’re outside a Task spawn (e.g. running mechanical work from a Bash hook script).
You want to force a specific (provider, model) that overrides modelMapping.
You’re debugging — explicit invocation surfaces the full mr-delegate.sh output.

# Force opencode-go/glm-5.1 for a heavy review, bypassing any modelMapping defaults
bash .claude/scripts/mr-delegate.sh t1k-code-reviewer \
  "audit src/auth/ for OWASP Top 10" \
  --provider opencode-go --model glm-5.1

Model + Provider Selection

When you call the explicit form, YOU pick (provider, model). When the interceptor fires, the mapping picks for you.

Read .claude/model-capabilities.md for model strengths/costs.
Read .claude/providers-config.json for available providers.
Choose the best (provider, model) for task complexity.

Pass via --provider <provider> --model <model> flags. Both required — no defaults.

Model Quick Reference

Need	Model	Provider	Why
Cheapest possible	`qwen3.5-plus`	opencode-go	10K req/5hr, basic quality
Best balance	`kimi-k2.6`	kimi or opencode-go	Good quality + reasonable cost
Best reasoning	`glm-5.1`	opencode-go	Complex tasks, worth the cost
Long context (1M)	`minimax-m2.7`	opencode-go	Large file analysis
Fast prototyping	`mimo-v2-pro`	opencode-go	Quick code generation

Full details: read .claude/model-capabilities.md.

Safety

Every delegation enforces:

Tool whitelist from the agent’s own frontmatter (Claude Code respects tools: / disallowedTools:).
Permission mode read from agent frontmatter; safe fallback (plan) if missing.
Max turns from agent frontmatter; default 25 if missing.
Budget cap from agent frontmatter; default $5 if missing.
Timeout (5 minutes default).
No nested delegation (MR_SPAWNED guard at both the script and the interceptor).
Write lock (single write-capable agent at a time when mode=acceptEdits).
Telemetry (events sent to T1K cloud for monitoring).
excludeAgents list in t1k-config-mr.json — any agent here is never intercepted (e.g. t1k-architect, t1k-planner for tasks that genuinely need Opus).

Logs & Telemetry

Local logs: ~/.model-router/calls.jsonl (carries the agent name).
Tool usage: ~/.model-router/tool-usage.jsonl.
Worker schema: the existing role column carries the agent name (no migration).

See The1Studio/theonekit-model-router#42 for the v2 design rationale and #54 for the v3.3.0 kit-enforced Opus-family passthrough policy.
