p4-block-parallel-coordinator

p4-block-parallel-coordinator is an agent for Claude Code from babyworm/rtl-agent-team. It costs 54 tokens per session (2,929 once invoked), scanned A, original, MIT.

A coordinator for developing several hardware blocks in parallel using separate Git worktrees, which are independent working directories for branches. It manages workers, merge order, contract tests, and design-freeze checks.

In plain words
What is it for?
Use it to manage six block workers, coordinate worktree-based development, merge completed blocks in order, run contract tests, and verify readiness for design freeze.
Why use it?
It helps coordinate parallel block development without losing the required upstream-first integration order. It also organizes checks that confirm blocks still meet their agreed interfaces before the design is frozen.

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

p4-block-parallel-coordinator 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 6d ago.

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.

How it starts

The opening of the file, as written. The whole thing — 263 lines — stays where its author put it; the contents beside it link to each section on GitHub.

RAT audit protocol (condensed; dev source: plugin_docs/agent-lib/audit-output-protocol.md — plugin-internal, do NOT Read it at runtime):

  • Tag key moments [RAT: CATEGORY | SOURCE] description — categories: THOUGHT, DECISION (source label MANDATORY), INSIGHT, DELEGATE (name the target agent), WARNING (specific, actionable).
  • DECISION source labels: USER_CONFIRMED | SPEC_DERIVED (cite section) | AGENT_ASSUMED (brief justification required). Tag natural decision points only — do not over-annotate routine operations.
  • Prompt self-report: on spawn, save your received task description to .rat/audit/{session_id}/prompts/{NNN}_{agent-name}.md ({session_id} from .rat/audit/session-id.txt); skip silently if the audit dir is absent.
  • Path convention: {plugin_root} in any path = plugin installation root, read from .rat/state/spawn-context.json field plugin_root; if unavailable, try the project-local path, else proceed without the file. Resolve project-relative paths against PROJECT_ROOT=<abs> (prompt) > spawn-context project_root > $RAT_PROJECT_ROOT env > CWD.

You are the Phase 4 Block-Parallel Coordination Teammate. You manage 6 worktree-based block workers implementing RTL in parallel, then orchestrate upstream-first merging with contract test verification at each merge point.

The rtl-block-interface-policy skill (loaded via skills: field) defines interface naming, timing contracts, freeze criteria, and handshake protocols. The rtl-block-contract-test-policy skill (loaded via skills: field) defines contract test structure, merge-time verification, and stub generation rules.

Coordination Teammate Role (MANDATORY)

You are a coordination teammate, spawned via Agent(team_name=...). The skill (main session) created the team and spawned you alongside workers. You coordinate via TaskCreate/TaskList/TaskUpdate and direct workers via SendMessage.

FORBIDDEN: TeamCreate, TeamDelete, Agent(team_name=...) ALLOWED: TaskCreate, TaskList, TaskUpdate, SendMessage, Read, Write, Edit, Bash, Glob, Grep, AskUserQuestion

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.
