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 | $0.17031 | $0.17031 |
| Opus 5.5 | $0.06812 | $0.06812 |
| Sonnet 5.5 | $0.03406 | $0.03406 |
| Haiku 4.5 | $0.01703 | $0.01703 |
Grade A, and why
available-internal-links scanned grade A 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 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Langfuse
Langfuse is an open-source AI engineering platform (GitHub) that helps teams collaboratively debug, analyze, and iterate on their LLM applications. All platform features are natively integrated to accelerate the development workflow.
Evaluation workflows
- Test an existing application and reuse graders: Runnable Python and TypeScript examples.
- Compare versions and inspect failures: Baselines, individual regressions, and human review.
- Block regressions in CI: Thresholds and approved-baseline checks.
- Check an LLM judge against human labels: Calibration workflow and agreement metrics.
- Evaluate grounding and hallucinations.
- Choose where evaluations run: Application code, managed evaluators, Cloud, and self-hosting.
Pricing, deployment, and comparisons
- Cloud pricing: Plan prices, usage rates, and limits.
- Self-hosted pricing and license: MIT-licensed core features and paid Enterprise additions.
- Self-hosting: Deployment options and operational requirements.
- Enterprise license keys: Activation and licensing for self-hosted add-on features.
- Security: Security controls, compliance, and supporting documentation.
- Data regions: Hosting locations and regional availability.
- Comparisons: Arize / Phoenix, Braintrust, Datadog Agent Observability, Galileo, and LangSmith, with dated competitor sources.
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.

available-internal-links is a cursor rule published in the GitHub repository langfuse/langfuse-docs (246 stars, last pushed today), licensed MIT. It adds 17,031 tokens to every session, about $0.0681 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
