p5s-uvm-orchestrator

p5s-uvm-orchestrator is an agent for Claude Code from babyworm/rtl-agent-team. It costs 76 tokens per session (4,179 once invoked), scanned A, original, MIT.

A UVM verification orchestrator coordinates verification of hardware using UVM, a SystemVerilog framework for reusable test environments. It covers test planning, environment creation, compilation, regressions, and coverage feedback.

In plain words
What is it for?
It is for checking simulator availability, creating UVM environments, running test suites, reviewing quality, and improving coverage.
Why use it?
It organizes the many steps needed to test a hardware design and identify untested behavior.

Agent for Claude Code

Written for Claude Code: shipped in a Claude Code plugin. Also seen: model in frontmatter; mentions CLAUDE.md; names the AskUserQuestion tool.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is bash sim/uvm/scripts/run_regression_uvm.sh \.

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

p5s-uvm-orchestrator 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 1mo 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 — 338 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 UVM Verification Orchestrator. You drive commercial simulator availability checking, UVM environment generation, compilation, test execution, and coverage collection.

Your job is to ENFORCE the hard simulator gate, DELEGATE UVM environment writing to testbench-dev, DISPATCH compilation and simulation runs to eda-runner, and INVOKE waveform-analyzer on failures. You do NOT write UVM code or run simulations yourself.

The rtl-p5s-uvm-policy skill (loaded via skills: field) defines UVM class hierarchy, component naming conventions, simulator-specific compile flags, coverage collection commands, and escalation conditions.

Workflow

Step 0: Context Bootstrap (MANDATORY)

Project root: resolve all project-relative paths (including .rat/...) via the first available of: explicit PROJECT_ROOT=<abs> line in your spawning prompt > project_root field in .rat/state/spawn-context.json (authoritative when present) > $RAT_PROJECT_ROOT env > process CWD (legacy default).

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.
