DeepAgent Toolchain Plan (VCO)

When to use

Use this skill when:

• VCO router returns route_mode=confirm_required and you want a better, evidence-backed choice
• The task spans multiple domains/tools and you need a skill chain, not a single skill
• The user asks “用什么工具/技能最好？” / “怎么编排这套技能？”
• The conversation is long or messy and you need to re-anchor on goal → toolchain → verification

Non-goals (avoid redundancy)

• This is not a replacement for VCO routing. It is an augmentation that proposes a chain.
• This is not GitNexus. For code dependency/impact, use GitNexus overlays.
• This does not introduce long-term episodic memory (VCO governance disables it).

Runtime (Upstream vendoring)

DeepAgent upstream is vendored for reference / optional advanced runs:

• C:\Users\羽裳\.codex\_external\ruc-nlpir\DeepAgent\

VCO-managed runtime config and self-check scripts (no secrets stored/printed):

• C:\Users\羽裳\.codex\skills\vibe\config\ruc-nlpir-runtime.json
• pwsh C:\Users\羽裳\.codex\skills\vibe\scripts\ruc-nlpir\preflight.ps1

Core output (must)

Return a toolchain with:

1. Goal + deliverable (1–2 lines)
2. Chain steps (3–8 steps, each: skill/tool + why + expected artifact)
3. Verification points (at least 1 falsifiable check)
4. Fallbacks (what to do if a tool is unavailable)

Workflow

Step 1: Capture the task in a contract

• Goal (one sentence)
• Deliverable (code / plan / report / dataset / etc.)
• Constraints (time, no heavy deps, offline-only, etc.)

Step 2: Ask VCO router for a white-box view (recommended)

Run the router script in probe mode to get candidates + overlays in a machine-readable form:

• pwsh C:\Users\羽裳\.codex\skills\vibe\scripts\router\resolve-pack-route.ps1 -Prompt "<PROMPT>" -Grade L -TaskType planning -Probe -ProbeLabel "toolchain" -ProbeOutputDir outputs/runtime/router-probes

Then use the emitted confirm_ui + overlay advice to decide the chain.

Step 3: Build a minimal chain (DeepAgent principle)

Prefer a chain that:

• Starts with evidence acquisition (local docs / web / code graph)
• Then planning
• Then execution
• Ends with verification + review

Step 4: Guardrails

• If the chain requires web browsing, explicitly choose between:
  • web.run (fast structured browse)
  • playwright / turix-cua (dynamic/interactive)
• If the chain requires heavy model hosting (vLLM), provide a Lite alternative.

Suggested chains (templates)

A) “Research → report”

1. webthinker-deep-research (Lite) → outputs/webthinker/.../report.md
2. flashrag-evidence (local protocol checks) → citeable snippets
3. code-reviewer (if code changes) or verification-quality-assurance (if routing changes)

B) “VCO enhancement work (config/skills)”

1. flashrag-evidence (locate existing policy/overlays)
2. writing-plans (implementation plan with file paths + verify steps)
3. verification-before-completion (run check + router probe)
