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 | $0.04698 | $0.04698 |
| Opus 5 | $0.02349 | $0.02349 |
| Sonnet 5 | $0.00940 | $0.00940 |
| Haiku 4.5 | $0.00470 | $0.00470 |
Grade A, and why
presonus-studiolive-mcp phase-09-operation-maintenance.instructions.md 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 11d 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.

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

Phase 09: Operation & Maintenance
Standards: ISO/IEC/IEEE 12207:2017 (Maintenance Process, Operation Process)
XP Integration: Continuous Improvement, Sustainable Pace, Collective Ownership
🎯 Phase Objectives
- Operate system in production environment
- Monitor system health and performance
- Respond to incidents and problems
- Perform corrective, adaptive, and perfective maintenance
- Continuously improve based on feedback
- Plan and execute system evolution
📋 Incident and Maintenance Tracking via GitHub
Incident Tracking
Use GitHub Issues for incident management:
Template: Bug Report or create custom "Incident" template
Example Incident Issue:
Title: [INC-001] Login failures for users with special characters in email
Severity: High (P1)
Impact:
- Affects: ~500 users with '+' or '.' in email addresses
- User-facing: Login fails with 400 Bad Request
- Workaround: None currently available
- Revenue impact: Potential churn for affected users
Root Cause Analysis:
Related to #45 (REQ-F-AUTH-001: User Login)
Component: #79 (ARC-C-AUTH: Authentication Service)
**Cause**: Email validation regex doesn't handle RFC 5322 compliant addresses
**Fix**: Update validation to use proper email RFC compliance
Resolution:
Implements fix: #PR-155
Verified by: #156 (TEST-INC-001-REGRESSION)
Deployed: v1.2.1 hotfix on 2025-11-12
Labels: bug, incident, priority-high, phase-09
Maintenance Request Tracking
Maintenance Types (use labels):
maintenance-corrective: Fix defects (bugs)maintenance-adaptive: Adapt to environment changesmaintenance-perfective: Improve performance/featuresmaintenance-preventive: Prevent future issues
Example Maintenance Issue:
Title: [MAINT-PERF] Optimize database queries for user search
Type: Perfective Maintenance
Justification:
Performance degradation observed:
- User search response time: 2.5s (target: <200ms)
- Database CPU: 85% during peak hours
- N+1 query problem identified in user search endpoint
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.
