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 | $0.00049 | $0.00780 |
| Opus 5 | $0.00024 | $0.00390 |
| Sonnet 5 | $0.00010 | $0.00156 |
| Haiku 4.5 | $0.00005 | $0.00078 |
Grade A, and why
agentic-sdd-router 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 12d 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.
How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agentic SDD Router
Use this skill first for spec-driven development work. It chooses the current phase, loads only the needed phase skill, and prevents accidental jumps from vague intent to code.
Source Backing
This workflow is based on:
- Local guide:
/Users/nawodyaishan/Downloads/production-spec-driven-agentic-coding-guide.md - GitHub Spec Kit workflow: constitution, specify, clarify, plan, tasks, analyze/checklist, implement
- OpenAI Codex safety guidance: bounded sandboxing, explicit approvals for high-risk actions, and auditable tool activity
Phase Map
| User intent | Use skill |
|---|---|
| Set up SDD in a repo | agentic-sdd-bootstrap |
| Write or improve product intent | agentic-sdd-spec |
| Resolve unclear requirements | agentic-sdd-spec |
| Create a technical plan | agentic-sdd-plan |
| Review plan before coding | agentic-sdd-architecture-review |
| Break plan into agent tasks | agentic-sdd-tasks |
| Implement an approved task | agentic-sdd-implement |
| Verify implementation or review diff | agentic-sdd-verification-review |
| Detect drift, release notes, retrospective | agentic-sdd-drift-retro |
Required Order
For non-trivial production work, enforce this order:
bootstrap, if needed
-> spec
-> clarify, if needed
-> plan
-> architecture review and approval
-> tasks
-> implementation
-> verification and code review
-> drift check, release notes, retrospective
Routing Rules
- If there is no
spec.mdfor the requested work, route toagentic-sdd-spec. - If
spec.mdhas open questions or ambiguous requirements, stay inagentic-sdd-spec. - If there is no
plan.md, route toagentic-sdd-plan. - If
plan.mdexists but lacks approval, route toagentic-sdd-architecture-review. - If there is no
tasks.md, route toagentic-sdd-tasks. - If implementation is requested and the plan is not approved, stop and ask for architecture approval.
- If implementation is requested for high-risk areas, require explicit approval before edits:
- dependencies or lockfiles
- database migrations
- auth or authorization
- payments
- secrets or credentials
- production config, infrastructure, deployment
- If the user asks for parallel agents or subagents, allow them only inside the implementation or review phases and only for bounded, disjoint work.
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.

agentic-sdd-router is a skill published in the GitHub repository nawodyaishan/universal-mcp-sync (6 stars, last pushed 1mo ago), licensed MIT. It adds 49 tokens to every session and 780 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.
