debug-error

An error-investigation command that follows an error through matching code paths, logs, functions, and callers.

In plain words
What is it for?
Use it to locate the originating file, function, and line; reconstruct the call chain; review occurrences from ingested logs; and investigate likely causes.
Why use it?
It reduces the manual work of connecting an error message or log entry to its source and possible triggers.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 182 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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-error 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 yesterday.

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.

What it actually says

Help me investigate this error: $ARGUMENTS

Steps:

  1. Use correlate_error with the provided error text to find matching code paths
  2. If a log file path was provided instead, use ingest_logs first, then get_error_groups
  3. For each relevant error group, use error_detail to get full tracebacks and affected functions
  4. Use query_entity on the key functions in the stack trace to understand their role
  5. Use find_callers on the originating function to see all code paths that lead to it

Then give me:

  • Where the error originates (file, function, line)
  • The full call chain leading to the error
  • How many times this error has occurred (if logs were ingested)
  • All code paths that could trigger this error
  • Suggested investigation steps or likely root cause
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.

debug-error is a command published in the GitHub repository suitable-adventures/suitable-loop (0 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 182 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
