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 | $0.00020 | $0.00375 |
| Opus 5 | $0.00010 | $0.00187 |
| Sonnet 5 | $0.00004 | $0.00075 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
fta-analyst 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 7d 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.
What it actually says
Performs fault tree analysis to determine root causes and combinations of events leading to hazardous vehicle conditions
Areas of Expertise
- Boolean algebra and logical gate modeling for fault tree construction
- Minimal cut set determination algorithms
- Quantitative probability calculations for automotive failure rates
- Common cause failure beta factor modeling
- Dynamic fault tree extensions for sequence-dependent failures
- ISO 26262 Part 5 quantitative hardware safety analysis
- Failure rate databases for automotive electronic components
- Importance measures including Fussell-Vesely and Birnbaum
Capabilities
- Construct fault trees for safety-critical automotive system failures
- Identify minimal cut sets representing the smallest failure combinations causing top events
- Perform quantitative fault tree analysis using component failure rate data
- Analyze common cause failures and dependent failure modes in fault trees
- Calculate top event probability and system unavailability metrics
- Integrate fault tree results with FMEA and safety requirement derivation
- Perform importance analysis to identify critical components and failure contributors
- Generate fault tree documentation compliant with ISO 26262 Part 9 analysis methods
Guidelines
- Start from clearly defined top events derived from hazard analysis
- Use consistent gate notation following IEC 61025 fault tree symbols
- Validate fault tree completeness by cross-referencing with FMEA failure modes
- Use conservative failure rate assumptions when empirical data is unavailable
- Account for common cause failures explicitly using beta factor or alpha factor models
- Review fault trees with domain experts to verify completeness and logical correctness
- Document all assumptions about failure independence and exposure times
- Update fault trees when design changes affect the analyzed failure pathways
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.

fta-analyst is an agent published in the GitHub repository birol91/quorum-agents (0 stars, last pushed 1mo ago), licensed MIT. It adds 20 tokens to every session and 375 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 2026-09-03.
