eval-harness

eval-harness is a skill for Claude Code, Codex from MiaoDX/roboclaws. It costs 33 tokens per session (1,471 once invoked), scanned A, original, MIT.

A skill for choosing and running validation checks, product tests, evaluation suites, and live-agent tests for Roboclaws changes. Roboclaws is the project this add-on supports.

In plain words
What is it for?
It is for validating plans, pull requests, and agent-facing changes, then locating the resulting reports and evidence for promoting regressions.
Why use it?
It helps maintainers decide which checks apply to a plan or code change and records why checks were run, skipped, failed, or blocked.

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

eval-harness 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.

The opening of the file, as written. The whole thing — 147 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Eval Harness

Use this skill when a Roboclaws plan, diff, PR, or agent-facing change needs one maintainer proof surface. The skill answers:

  1. which deterministic gates, product runs, eval suites, and live-agent evals are relevant;
  2. why each row was selected, skipped, run, failed, or blocked;
  3. where the resulting reports and regression-promotion evidence live.

It is an orchestration skill, not a robot behavior skill. Keep household-world task strategy in household-world; keep reusable robot capability semantics in MCP tools and capability profiles.

Use Just only as the human-facing facade shown below. Frozen rows execute their package owners directly: eval rows use python -m roboclaws.evals.cli, and product rows use python -m roboclaws.cli.main run surface. Keep the subprocess boundary for row timeout and isolation; do not route an executing row back through Just or add a second command registry. The eval CLI grammar is an optional documented kebab-case tool name followed by key=value arguments.

Commands

Recommend rows without running them:

just agent::eval recommend plan=docs/plans/example.md budget=focused

Execute relevant rows for a plan or diff:

just agent::eval execute plan=docs/plans/example.md budget=focused
just agent::eval execute since=origin/main budget=focused
just agent::eval execute profile=baseline-core budget=focused max_parallel=4

Pass scene=<source>/<index>,... to expand rows whose catalog uses scene_scope=selected; the current scene-portable rows are the MapBuild product rows. Case identity, dependencies, commands, and result schema are resolved before local execution. Scheduling respects shared backend locks and writes one result per frozen benchmark case.

Refresh the current baseline at the appropriate cost tier:

just agent::eval execute profile=baseline-core budget=focused
just agent::eval execute profile=baseline-live-default budget=focused
just agent::eval execute profile=baseline-refresh budget=focused

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.
