router-dispatch-build

router-dispatch-build is a skill for Claude Code, Codex from cintia09/CodeNook. It costs 0 tokens per session (540 once invoked), scanned A, original, MIT.

A tool that builds the JSON message used when the router hands work to a plugin or built-in skill. It limits the message to 500 UTF-8 bytes and records each handoff for later auditing.

In plain words
What is it for?
Use it to create dispatch messages with a target, user request, optional task, workspace, and available plugins.
Why use it?
It gives delegated work a consistent format and prevents oversized messages from breaking the handoff process.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

router-dispatch-build scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

The scan reads SKILL.md. This mod also ships 2 executable files (_build.py, build.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

router-dispatch-build (builtin skill)

Role

Builds the canonical dispatch payload that the router sub-agent emits when it decides to hand off to a plugin worker or a builtin skill.

Two responsibilities:

  1. Construct a JSON payload conforming to architecture §3.1.7: {role, target, task?, user_input, context: {plugins}} (context.active_phase is RESERVED for M4 and is currently always omitted — the resolver/orchestrator that owns phase state is not wired into the router until M4.)
  2. Enforce the 500-byte hard limit (decision #T-3) — truncating user_input to 200 chars + "..." if needed; failing if the envelope still doesn't fit after truncation. The limit is measured in UTF-8 bytes (CJK-safe).
  3. Audit the dispatch by calling dispatch-audit emit with the final payload, so the architectural invariant "every handoff is logged" holds even when the router builds payloads inline.

CLI

build.sh --target <plugin-id|skill-name>
         --user-input "<text>"
         [--task <T-NNN>]
         [--workspace <dir>]
         [--json]
  • --target — required; either an installed plugin id or a builtin skill name. The presence of <ws>/.codenook/plugins/<target>/plugin.yaml determines role (plugin-worker vs builtin-skill).
  • --user-input — required.
  • --task — optional active task id.
  • --workspace — defaults to upward .codenook/ search.
  • --json — output mode (currently the only mode).

Exit codes

code meaning
0 payload built + audited; envelope on stdout
1 manifest missing OR payload still >500 bytes after truncate
2 usage error

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
