debug-task

A troubleshooting guide for problems in the infrastructure that runs coding-agent tasks, such as incorrect folders, files, virtual environments, browser startup, retries, or missing instructions.

In plain words
What is it for?
Use it to investigate wrong paths, incorrect working directories, browser failures, repeated retries, failed skill loading, and misleading task-failure reports.
Why use it?
It treats wasted steps and workarounds as signs of a platform problem, helping teams find the underlying cause instead of accepting that the agent eventually recovered.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 B, and why

debug-task scanned grade B with 2 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 2d 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 Task Infra

Debug agent task execution infrastructure issues by analyzing agent logs.

Core Philosophy

Every agent failure, detour, or workaround is an infra/platform bug — not an agent problem.

When an agent:

  • Tries a wrong file path then searches for the right one → catalog or path resolution bug
  • Uses wrong CLI syntax then self-corrects → skill docs not loaded or incomplete
  • Takes a screenshot but can't find/view it → tool integration bug
  • Retries a command with different args → missing docs or unclear API
  • Reflects "no failures" when there were failures → reflection prompt bug

Even if the agent eventually succeeds, each detour:

  1. Wastes tokens and time
  2. Signals a gap in the platform that WILL hit other tasks
  3. Must be traced to a specific infra root cause and filed as a bug

Do NOT dismiss detours as "the agent will self-correct." Your job is to find every single failure step, trace it to a code/config/prompt root cause, and report it.

When to use

When a task execution shows symptoms like:

  • Agent sees unexpected files or can't find expected ones
  • Agent runs in wrong working directory
  • Browser (Ziniao/Chrome) fails to start or takes multiple retries
  • Task uses wrong Python environment
  • Store context (bookmarks, browser config) missing from agent prompt
  • Agent repeats same bash command 3+ times (infra issue, not agent fault)
  • Agent repeats browser-open attempts (browser startup failure)
  • Agent can't load skills (wrong skill path or skill not synced)
  • Agent passes wrong arguments to tools (schema mismatch)
  • Agent uses workarounds for things that should "just work"
  • Agent's post-task reflection misses failures that clearly happened

Environment first: are you in WSL debugging a native-Windows server?

Before running ANY command below, figure out where the server actually runs. vibe-seller ships as a native-Windows install and as a Linux/WSL install, and the two do not share a data directory. Debugging the wrong one is the single biggest time-sink — you'll read a stale DB, grep empty logs, and "fix" a store that isn't the one serving traffic.

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.

debug-task is a skill published in the GitHub repository zpoint/vibe-seller (57 stars, last pushed 9d ago), licensed Apache-2.0. It adds 31 tokens to every session and 5,816 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (enumerates other installed skills, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
