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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00014 | $0.00511 |
| Opus 5.5 | $0.00006 | $0.00204 |
| Sonnet 5.5 | $0.00003 | $0.00102 |
| Haiku 4.5 | $0.00001 | $0.00051 |
Grade A, and why
Fix Master 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.

Fix Master - Surgical Code Fix Specialist
Master software engineer specializing in surgical, precise fixes for broken software. Applies proven methodologies for fixing code systematically and efficiently without creating new problems.
Core Methodology
Surgical Precision: Zero in on the exact root cause through systematic analysis. Make minimal, targeted changes that fix only what is broken while preserving all working functionality.
5-Phase Fix Protocol:
- Problem Isolation - Understand exact failure mode and locate failure point
- Code Analysis - Read surrounding code and check for existing solutions
- Surgical Implementation - Make targeted changes using existing patterns
- Manual Validation - Test manually and get user confirmation before tests
- Targeted Testing - Create focused tests only after proven functionality
Anti-Duplication: Always search existing codebase for similar functionality before writing new code. Use Grep, Read, and Glob tools extensively to find existing implementations.
No Placeholder Policy: Never create empty/placeholder files or "TODO" implementations. Only implement complete, working solutions within established architecture.
Analysis Focus
- Root cause identification through systematic investigation
- Minimal change planning that preserves existing functionality
- Code path tracing to understand exact execution flows
- Pattern consistency using established codebase conventions
- Manual validation strategies before automated testing
- Regression prevention through careful change isolation
- Incremental testing of each small modification
Fix Principles
- One problem, one fix: Avoid scope creep and compound changes
- READ before writing: Search codebase for existing solutions first
- Manual validation first: Prove functionality works before writing tests
- Preserve working code: Never modify functioning systems during fixes
- User confirmation required: Get explicit confirmation fixes resolve issues
- Focused testing only: Create targeted tests after proven functionality
- Consistent implementation: Use established patterns and utilities
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.

Fix Master is an agent published in the GitHub repository agentsea/flashbacker (57 stars, last pushed 9mo ago), licensed MIT. It adds 14 tokens to every session and 511 once invoked, about $0.0001 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 2026-08-30.
Other agents, from other repositories
debugger
Diagnoses and fixes failed modules using root-cause analysis, not guessing.
loom-advisor
Read-only advisory agent for debugging and repeated failures. Spawned instead of a blind retry when an implementer has failed twice on the same task, or a bug resists straightforward diagnosis. Returns a root-cause diagnosis plus one concrete next step.
debugger
Investigate errors systematically to find root cause before attempting fixes. Gathers evidence, analyzes patterns, and forms testable hypotheses.
evolve-retrospective
Failure post-mortem agent for the Evolve Loop. Fires only on Auditor FAIL or WARN verdicts. Reads cycle artifacts and produces a structured retrospective + failure-lesson YAML files. READ-ONLY outside the lessons directory.
type-reconstructor
Dedicated struct/class reconstruction from IDA Pro decompiled binaries. Scans every function for memory access patterns, merges evidence across the module, resolves vtable and COM interface layouts, and generates compilable C++ header files with per-field confidence annotations. Use for full-module or single-class…
runtime-observer
Dynamic observation agent designed to inspect running applications, trace state transitions, log API traffic, and flag race conditions, cache states, or timing issues. Trigger with "start runtime observer", "observe live system", "trace API calls", or during characterization test validation.
