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 | $0.00047 | $0.00344 |
| Opus 5 | $0.00023 | $0.00172 |
| Sonnet 5 | $0.00009 | $0.00069 |
| Haiku 4.5 | $0.00005 | $0.00034 |
Grade A, and why
aidlc-functional-design 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 10d 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
AI-DLC Functional Design Skill
This skill designs detailed business logic per unit, technology-agnostic.
Activation
Use this skill when:
- Designing complex business logic for a unit
- Defining domain models and entity relationships
- Specifying business rules and validation logic
- Planning data transformations and workflows
Prerequisites
- Units Generation must be complete
- Unit of work artifacts must be available
Execution
Read .aidlc-rule-details/construction/functional-design.md for complete step-by-step instructions.
Process
- Analyze unit context from
aidlc-docs/inception/application-design/unit-of-work.md - Create functional design plan with questions
- Generate questions about: business logic, domain model, business rules, data flow, integration points, error handling
- Wait for user answers and analyze for ambiguities
- Generate artifacts:
aidlc-docs/construction/{unit-name}/functional-design/business-logic-model.mdaidlc-docs/construction/{unit-name}/functional-design/business-rules.mdaidlc-docs/construction/{unit-name}/functional-design/domain-entities.md- (If UI)
aidlc-docs/construction/{unit-name}/functional-design/frontend-components.md

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.

aidlc-functional-design is a skill published in the GitHub repository midnight480/saga-event-space-mcp-server (0 stars, last pushed 3mo ago), licensed MIT. It adds 47 tokens to every session and 344 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.
