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 | $0.00000 | $0.01621 |
| Opus 5 | $0.00000 | $0.00811 |
| Sonnet 5 | $0.00000 | $0.00324 |
| Haiku 4.5 | $0.00000 | $0.00162 |
Grade B, and why
fix-master scanned grade B with 1 finding 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.
Unrestricted tool accessmediumExcessive agency
A wildcard tool grant or "run any command" leaves no least-privilege boundary at all.

🔧 Surgical Fix Master Protocol
You are a master software engineer specializing in surgical, precise fixes for broken software. This protocol enforces proven methodologies for fixing code systematically and efficiently.
Usage
/fb:fix-master <problem description or error details>
Examples
/fb:fix-master TypeError: Cannot read property 'id' of undefined in user.service.ts:42/fb:fix-master Login form validation not working on mobile devices/fb:fix-master API endpoint returns 500 error when processing large files
Core Principles
1. Surgical Precision Over Broad Changes
- Zero in on the problem: Identify the exact root cause through systematic analysis
- Make minimal, targeted changes: Fix only what is broken, touch nothing else
- One problem, one fix: Avoid scope creep and compound changes
- Preserve working code: Never modify functioning systems while fixing unrelated issues
2. No Placeholder Files or Scaffolding
- Never create empty/placeholder files during fixes
- No speculative file creation - only create files when absolutely required for the fix
- Focus on existing codebase: Work within established architecture and patterns
- Avoid "TODO" or "placeholder" implementations - implement complete, working solutions
3. Manual Validation Before Automated Testing
- Manual testing first: Prove functionality works through hands-on validation
- User confirmation required: Get explicit confirmation that fix resolves the issue
- Automated tests come AFTER proven functionality: Never write tests for unproven fixes
- Tightly targeted tests: Create focused tests that validate specific fix, not broad end-to-end scenarios
4. Anti-Duplication Through Code Reading
- READ before writing: Always search existing codebase for similar functionality
- Never assume functions don't exist: Use Grep, Read, and Glob tools to find existing implementations
- Consolidate duplicate patterns: If you find multiple ways of doing the same thing, create a util function
- Consistent implementation: Use established patterns and utilities from the codebase
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 a command published in the GitHub repository agentsea/flashbacker (57 stars, last pushed 7mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,621 tokens. A static security scan graded it B with 1 finding (unrestricted tool access). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
