rudder: Skill for Claude Code

.agents/skills/maintainer/debug-run-transcript-maintainer/SKILL.md

debug-run-transcript-maintainer is a skill for Claude Code, Codex from Undertone0809/rudder. It costs 54 tokens per session (3,158 once invoked), scanned A, original, Apache-2.0.

A debugging skill for examining Rudder agent runs, including their IDs, transcripts, logs, execution traces, and failures. Rudder is the system whose agent runs are being investigated.

In plain words
What is it for?
Use it to investigate runtime errors, transcript parsing problems, finalization failures, missing output, and recent run behavior.
Why use it?
It helps determine what happened when a run fails, when records are incomplete, or when the final status does not match the actual work.

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

debug-run-transcript-maintainer scanned grade A with 1 finding 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.

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.

Debug Run Transcript

Analyze Rudder agent runs by reconstructing the execution story from the best available source.

Purpose

Runs fail for several different reasons:

  • the model/runtime emitted an error
  • the transcript parser missed useful structure
  • the event stream is incomplete
  • the stored excerpts are too shallow
  • a tool call succeeded, but Rudder's message/run lifecycle marked the workflow failed during stream finalization, persistence, or UI status mapping
  • the operator has only a partial run ID or limited context

This skill helps diagnose those cases without getting stuck on the wrong data source.

Debugging proves what happened in a run; it does not by itself prove that a product fix works. When a transcript diagnosis leads to a code, CLI, skill, runtime, or UI change, hand the work back to the lifecycle verification path and require product proof for the affected actor and terminal surface.

Source Priority

Always use sources in this order:

  1. Run-intelligence loader/API
    • Best default.
    • Reads run metadata, run events, and the underlying run log.
    • Reconstructs transcript entries with runtime-specific parsers.
  2. Filesystem run log fallback
    • Use when the local API is unavailable but run logs exist on disk.
    • Good for transcript/tool-call reconstruction.
  3. Direct database queries
    • Use only for targeted checks or when the first two paths are unavailable.
    • DB rows alone are not the full transcript story.

Important Lessons / Known Traps

  • Do not assume ~/.rudder/instances/dev/postgres-uri exists. In this repo it is not a reliable universal entrypoint.
  • Do not start with heartbeat_run_events and assume they are the complete transcript. They are supplemental run events, not the full parsed execution trace.
  • Do not write WHERE id LIKE 'prefix%' against uuid columns. Cast first: id::text ILIKE 'prefix%'.
  • Do not assume pnpm exec tsx works from the repo root here. Prefer the repo-local launcher:

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.
