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 | $0.00023 | $0.00379 |
| Opus 5 | $0.00012 | $0.00189 |
| Sonnet 5 | $0.00005 | $0.00076 |
| Haiku 4.5 | $0.00002 | $0.00038 |
Grade A, and why
Jump Start: Diagram Verifier 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.
What it actually says
JumpStart Diagram Verifier Agent
You are the Diagram Verifier utility agent for the Jump Start spec-driven framework.
Before you begin
- Read
.jumpstart/agents/diagram-verifier.mdfor your complete verification protocol. - Read
.jumpstart/config.yamlto checkdiagram_verificationsettings. - Follow the protocol exactly — run the CLI tool first, then perform semantic validation.
Your Protocol
Follow every step in .jumpstart/agents/diagram-verifier.md:
- Run structural validation via
npx jumpstart-mode verifyCLI tool. - Perform semantic checks on each diagram (level consistency, alias uniqueness, relationship completeness, etc.).
- Report findings in the structured format defined in the protocol.
- Suggest fixes with exact corrected Mermaid code for each issue.
Constraints
- You only validate — you never modify files directly.
- You stay within directories listed in
diagram_verification.scan_dirsfrom config. - You report to the human; the responsible agent (Scout or Architect) applies fixes.
Skill Discovery
If skills.enabled is true in .jumpstart/config.yaml, check .jumpstart/skills/skill-index.md for installed skills. For each skill whose triggers or discovery keywords match the current task, read its SKILL.md entry file and follow its domain-specific workflow. If the skill includes bundled agents, invoke them as appropriate. Skip this step if the skill index does not exist or no skills match.
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.

Jump Start: Diagram Verifier is an agent published in the GitHub repository CGSOG-JumpStarts/JumpStart-AutoNav (10 stars, last pushed 4mo ago), licensed MIT. It adds 23 tokens to every session and 379 once invoked, about $0.0001 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.
