What it does

Rudder Real Runtime Verifier Maintainer is an agent skill from Undertone0809/rudder. Use when verifying Rudder agent runtime behavior in a real local environment, especially MCP/native Rudder tools across Codex, Claude, OpenCode, Pi, or user-named runtimes. Trigger for requests like 真是/真实环境跑过吗, 排查所有 rudder tools, transcript/fallback verification, runtime MCP availability, provider matrix proof, or checking whether agents used Rudder tools instead of rudder CLI/Bash/curl fallback.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including reference files (for example `references/claude.md`, `references/codex.md` and `references/opencode.md`).

It sits in Development. It works with Model Context Protocol and Bash. The repository describes itself as: Open-source local Agent harness for self-improving agent teams: run agents, review work, and turn feedback into reusable skills. The licence is Apache-2.0.

When your agent uses it

  • Verifying Rudder agent runtime behavior in a real local environment
  • Especially MCP/native Rudder tools across Codex
  • User-named runtimes
  • Requests like 真是/真实环境跑过吗

Example prompts

  • “/rudder-real-runtime-verifier-maintainer”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. The local Rudder source of truth is identified, usually
  2. A real local run was triggered for that runtime, or an existing real local
  3. The transcript shows the expected Rudder MCP/native tool calls.
  4. There is no model-visible fallback to shell, Bash, curl, or rudder CLI for
  5. Tool results are not internally failed (isError, structured error,
  6. The terminal product effect was read back: issue status, comments, run
  7. Provider/model blockers are separated from Rudder adapter/tool blockers.

What it can do on your machine

Read from SKILL.md and the folder at commit 2676a5c. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Rudder Real Runtime Verifier Maintainer loads about 1.8k tokens when it runs, and up to ~5.2k if it reads all its reference files. Until then it costs about 110 tokens; SKILL.md has 911 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~110
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~5.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when verifying Rudder agent runtime behavior in a real local environment, especially MCP/native Rudder tools across Codex, Claude, OpenCode, Pi, or user-named runtimes. Trigger for requests like 真是/真实环境跑过吗, 排查所有 rudder tools, transcript/fallback verification, runtime MCP availability, provider matrix proof, or checking whether agents used Rudder tools instead of rudder CLI/Bash/curl fallback.

Rudder Real Runtime Verifier Maintainer

Verify Rudder agent runtime behavior on the user's real local Rudder instance. This is a black-box runtime acceptance workflow, not an implementation or code review workflow.

Default to Chinese when the user asks in Chinese. Put the current truth first: which runtimes passed, failed, or were blocked, and what transcript evidence proves it.

Role Boundary

Default to verification and diagnosis only:

  • Run real local runtime probes and inspect run transcripts, logs, API state, issue state, comments, and run metadata.
  • Create disposable orgs, agents, issues, and runs when needed for proof.
  • Separate provider/model failure from Rudder adapter failure.
  • Report exact blockers and smallest likely fixes.
  • As an independent verifier, do not edit source, configs, Git state, or product docs. Return findings to the implementer. The parent retains any existing fix authority; verification does not require that authority to be repeated.

If the user asks to fix the issue, hand back to the lifecycle implementation route or make the smallest explicit patch, then require this skill's real runtime proof again before claiming done.

When This Skill Wins

Use this skill when the core question is whether an agent runtime actually did the work through Rudder-managed tools in a real local run.

Typical prompts:

  • "你所有的 agent runtime 都本地测过跑过真实环境了吗?"
  • "OpenCode and Pi agent 你也测了吗?"
  • "看 transcript，别让它 fallback 用 rudder cli"
  • "排查所有 rudder tools，都试一遍"
  • "MCP tool 报 org id/auth 问题，正常 agent 调 tool 不该传 org"
  • "Codex/Claude/OpenCode/Pi 真实环境跑一下"

If the user asks for general product acceptance that is not runtime/tool-call specific, use product-acceptance-verifier-maintainer instead. If the user provides only one failed run id and wants root cause, use debug-run-transcript-maintainer first, then return here for rerun proof after a fix.

Runtime Matrix

Select the runtime matrix from the user's request and the changed integration. Test one runtime for a runtime-specific claim. Use the full supported matrix for an explicit all-runtime claim or a shared adapter/tool change that affects it:

  • Codex
  • Claude Code
  • Hermes
  • OpenCode
  • Pi
  • Cursor

Do not treat a Codex pass as proof for another runtime.

Read only the relevant reference files:

  • references/probe-workflow.md: real local setup, disposable data, probe script expectations, and proof levels.
  • references/transcript-evidence.md: how to prove tool use and reject CLI fallback from logs.
  • references/codex.md: Codex MCP transcript shape and known traps.
  • references/claude.md: Claude MCP transcript shape and strict config traps.
  • references/opencode.md: OpenCode MCP transcript shape, provider/model caveats, JSONL parser expectations, and final-text pitfalls.
  • references/pi.md: Pi native extension transcript shape, schema/error propagation traps, and 429/auth/provider separation.
  • references/reporting.md: verdict format, mutation ledger, and pass/fail language.

Acceptance Standard

A runtime passes only when all are true:

  1. The local Rudder source of truth is identified, usually GET /api/health on http://127.0.0.1:3100.
  2. A real local run was triggered for that runtime, or an existing real local run was inspected with enough raw transcript/log evidence.
  3. The transcript shows the expected Rudder MCP/native tool calls.
  4. There is no model-visible fallback to shell, Bash, curl, or rudder CLI for Rudder work.
  5. Tool results are not internally failed (isError, structured error, rudder_cli_command_failed, missing required argument, auth/org failure).
  6. The terminal product effect was read back: issue status, comments, run status, final text, API result, or another requested surface.
  7. Provider/model blockers are separated from Rudder adapter/tool blockers.

If the user requires "all tools", do not only run a happy-path issue workflow. Run or request a manifest-driven coverage plan: list every exposed tool, verify schemas load, check runtime-managed identity is not model-provided, and execute representative read/mutate/file/image/pagination/error cases. Mark unexecuted tools as not covered.

Default Probe Ladder

Use the smallest probe that answers the question, then escalate only as needed:

  1. Tool availability probe: call rudder_agent_me, require final answer to say MCP/tool path and no fallback.
  2. Issue workflow probe: seed an issue, then require rudder_issue_context, rudder_issue_checkout, rudder_issue_comment, and rudder_issue_done; read back final issue status and comments.
  3. Representative matrix probe: add read/list/pagination/file/comment/image examples such as rudder_runs_errors, rudder_library_file_ref, inbox/context, review, chat, or automation.
  4. Full manifest audit: prove every exposed Rudder tool has a stable name, schema, description, and handler classification; execute safe read-only tools and representative mutating tools in disposable data.

Known Judgment Rules

  • A successful final answer is not enough. Inspect raw or parsed transcript.
  • A tool call name in prompt text is not evidence. Use structured tool-call events or parsed run-intelligence entries.
  • A run can fail after completing the product effect. Report that separately: tool/product effect passed; runtime finalization failed.
  • A provider 429/auth/model error before any tool call is not an MCP auth/org bug. Mark it blocked_provider.
  • If a tool result contains isError: true but the runtime marks the tool call completed, treat the runtime as failed or at least suspect until fixed.
  • Internal runtime-owned bridges may execute a server process. That is acceptable only if the model-visible action is a typed Rudder tool and runtime env owns identity. It is not acceptable if the model uses Bash/curl or runs rudder ... itself for Rudder work.

Output

Use references/reporting.md for the full shape. At minimum include:

  • overall verdict: PASS, FAIL, or QUESTION for the requested matrix; observed required behavior failure yields FAIL; otherwise missing required proof or provider access yields QUESTION; complete required proof yields PASS
  • verdict per runtime: PASS, FAIL, BLOCKED_PROVIDER, PARTIAL, or NOT_RUN
  • run IDs, issue IDs, org IDs when disposable data was created
  • observed tool names
  • whether CLI/Bash/curl fallback was observed
  • internal tool errors
  • terminal product effect
  • skipped coverage and why
  • mutation ledger

Do not say "all green" if any runtime is blocked, substituted, partial, or only covered by simple agent_me.
