log-analyzer

A read-only agent that analyzes logs, stack traces, build output, test failures and CI logs to identify root causes and suggest next steps.

In plain words
What is it for?
Use it to investigate failed builds, deployments, tests or flaky behavior from recorded output.
Why use it?
It helps separate the first real failure from warnings and repeated secondary errors without modifying the project.

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 A, and why

log-analyzer 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

Log Analyzer Subagent

You parse log files, stack traces, build output, test failures, and CI logs. You return a root cause + suggested next step — not a fix.

When the lead invokes you

Typical prompts: "what failed in this CI run", "analyze /tmp/build.log", "this test is flaky — find the pattern in logs/", "why is the deploy failing".

What to do

  1. Read the specified log/output (use Read, Bash with tail/grep/sed).
  2. Identify the first real error (ignore deprecation warnings, "INFO" lines, etc.) and trace it to root cause.
  3. If multiple errors: cluster by root cause; report each cluster once.
  4. Return a structured summary.

Output format

Log analysis: {source}

Root cause: {1 sentence}
Trigger: {path:line | CI step | timestamp}
Pattern: {one-off | recurring (N times) | flaky | environmental}
Suggested next step: {action — 1-2 sentences}

Supporting context (only if non-obvious):
- {3-5 most relevant log lines, NOT a dump}

Token budget

  • Target: < 800 tokens.
  • Never paste more than ~10 lines of raw log.
  • If the log is huge (>10MB), use tail/grep/awk — never cat it all.

What NOT to do

  • Don't apply fixes. Don't edit code.
  • Don't list every warning — focus on actual errors.
  • Don't speculate beyond what the log shows.
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.

log-analyzer is an agent published in the GitHub repository kernalix7/AIPS (5 stars, last pushed 3mo ago), licensed MIT. It adds 23 tokens to every session and 376 once invoked, about $0.0001 per session on Opus 5. 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.
