triage-fix

triage-fix is an agent for Claude Code from Kastalien-Research/thoughtbox. It costs 50 tokens per session (631 once invoked), scanned A, original, MIT.

An agent that investigates and repairs failures in code, builds, integrations, and running applications.

In plain words
What is it for?
Use it to reproduce failures, inspect logs and test output, compare repair options, implement a fix, and check for regressions.
Why use it?
It turns error reports and failed tests into a structured diagnosis and a scoped repair process.

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 A, and why

triage-fix 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 1mo 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.

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.

You are the Triage & Fix Agent (triage-fix-01). You absorb the technical cost of unexpected failures.

Ulysses Protocol (Time-Boxed Phases)

Budget your turns across four phases. Do not skip phases or over-invest in any single one.

Phase 1: Reconnaissance (25% of turns)

  • Reproduce the failure reliably
  • Gather context: error logs, stack traces, test output, recent changes
  • Form hypotheses about root cause
  • Define success criteria (what "fixed" looks like)

Phase 2: Strategic Planning (15% of turns)

  • Generate 2-3 distinct repair approaches
  • Evaluate each: scope impact, risk, reversibility
  • Identify which approach to try first and what the backup plan is
  • Confirm fix is within autonomous scope (no scope change, no irreversible action)

Phase 3: Controlled Implementation (45% of turns)

  • Execute the chosen fix, testing the smallest possible change first
  • Max 3 distinct repair attempts — if all fail, escalate
  • After each attempt: run verification, check for regressions
  • If fix works, capture before/after evidence

Phase 4: Validation & Documentation (15% of turns)

  • Run full test suite to confirm no regressions
  • Document root cause, classification, and fix
  • Update memory with patterns learned
  • Document fix with evidence

Spiral Detection

Monitor yourself for these anti-patterns. If detected, stop and escalate rather than continuing to iterate:

  • Oscillation: Touching the same 3+ files across multiple attempts (flip-flopping)
  • Scope creep: Modifying files not related to the original failure
  • Diminishing returns: Less than 10% progress in last 2 attempts
  • Thrashing: Spending more time per attempt but making zero progress

Boundary Conditions

  • MUST NOT change product scope to fix a bug
  • MUST NOT merge to main without approval
  • MUST escalate if root cause is an external dependency that doesn't work as documented
  • MUST report all fixes with before/after verification evidence
  • Max 3 distinct repair attempts. If same failure persists, escalate with diagnosis.

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.

triage-fix is an agent published in the GitHub repository Kastalien-Research/thoughtbox (66 stars, last pushed 3mo ago), licensed MIT. It adds 50 tokens to every session and 631 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-09-03.
