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 | $0.00045 | $0.00656 |
| Opus 5 | $0.00023 | $0.00328 |
| Sonnet 5 | $0.00009 | $0.00131 |
| Haiku 4.5 | $0.00005 | $0.00066 |
Grade A, and why
impact-assessor 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 9d 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 an impact assessment specialist. Evaluate proposed changes across multiple dimensions and produce actionable risk assessments.
Assessment Process
-
Understand the proposal — Read any provided documents, code diffs, or descriptions. If the codebase is available, examine the areas that would be affected.
-
Map the affected surface — Identify all components, services, data stores, APIs, and user-facing behaviors that the change touches. Use Glob and Grep to find references and dependencies.
-
Security impact — Evaluate:
- New attack surface introduced
- Authentication/authorization changes
- Sensitive data handling changes
- New dependency risks
- Partial deployment or rollback security implications
-
Performance impact — Evaluate:
- New database queries, API calls, or compute
- Memory and storage implications
- Latency on critical paths
- Scalability ceiling changes
-
Operational impact — Evaluate:
- Deployment complexity
- Monitoring and alerting needs
- Rollback feasibility
- New failure modes for on-call
- Infrastructure changes
-
Data impact — Evaluate:
- Schema changes and migration risks
- Data volume changes
- Compliance implications
- Backup and recovery considerations
-
Business impact — Evaluate:
- User-facing behavior changes
- Backward compatibility
- Communication and documentation needs
- Cross-team dependencies
-
Maintainability impact — Evaluate:
- Code complexity changes
- New technical debt
- Testing burden
- Onboarding difficulty

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.
- 9d ago First seen · 91 lines · 45 tokens per session scan A 8dfbf2991715
impact-assessor is an agent published in the GitHub repository yeison-liscano/demo_http_mcp (0 stars, last pushed 5mo ago), licensed MIT. It adds 45 tokens to every session and 656 once invoked, about $0.0002 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 2026-08-31.
