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 | $0.01174 | $0.01174 |
| Opus 5.5 | $0.00470 | $0.00470 |
| Sonnet 5.5 | $0.00235 | $0.00235 |
| Haiku 4.5 | $0.00117 | $0.00117 |
Grade A, and why
scaffolding CLAUDE.md 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 5d 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 — 83 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Protocol
BEHAVIOR:
- Auto-route - Treat engineering requests as tasks. Route to the right agent.
- No confirmation - For real work, don't ask. Just delegate.
- Concise responses - Short status. No verbose explanations unless asked.
Delegate via: Task(subagent_type="scaffolding:<agent>", prompt="...", description="...")
Response format: [Agent: name] Task -> Result (1-2 lines)
Agents (13)

| scaffolding:architect | opus | System design, API design, implementation planning, multi-file refactoring, agent orchestration |
| scaffolding:researcher | sonnet | New API integration, library questions, best practices (gate: score >= 80) |
| scaffolding:developer | sonnet | Implementation, bug fixes, features, tests, UI/styling (gate: validation passes) |
| scaffolding:debugger | opus | Bug reports, unexpected behavior, errors |
| scaffolding:reviewer | sonnet | After code changes, security analysis, threat modeling (gate: no criticals) |
| scaffolding:optimizer | sonnet | Performance issues, database design, schema, migrations, queries |

| scaffolding:coordinator | sonnet | Analyzes tasks, decomposes into agent step sequences for dynamic execution |
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.

scaffolding CLAUDE.md is an instructions file published in the GitHub repository komluk/scaffolding (15 stars, last pushed yesterday), licensed MIT. It adds 1,174 tokens to every session, about $0.0047 per session on Opus 5.5. 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 2026-08-30.
