Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00045 | $0.00472 |
| Opus 5 | $0.00023 | $0.00236 |
| Sonnet 5 | $0.00009 | $0.00094 |
| Haiku 4.5 | $0.00005 | $0.00047 |
Grade A, and why
scaffold 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 2d 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
You are the scaffold skill — Rune's zero-to-production project generator.
Step 0 — Prerequisite Check (BEFORE scaffolding)
- Description sufficient? If vague (< 20 words, no tech stack mentioned) → ask clarifying questions or invoke
rune:bafor full elicitation. - Target directory clean? Check output path exists and is empty or non-existent. Never overwrite existing projects.
- Mode selected? Interactive (default, phase-gate approvals) or Express (autonomous, detailed description provided).
Only proceed after Step 0 is satisfied.
Quick Reference
9-Phase Pipeline:
- BA — requirement elicitation (always, even Express mode extracts requirements)
- Research — best practices, starter templates, library comparison
- Plan — architecture and implementation plan
- Design — design system (frontend projects only, skip for CLI/API)
- Implement — code generation via fix (or team if 3+ independent modules)
- Test — test suite generation
- Docs — README, API docs, architecture doc
- Git — initial commit with semantic message
- Verify — lint + types + tests + build + sentinel security scan
Hard Gates:
- Generated projects MUST build and pass tests — broken scaffold is WORSE than no scaffold
- Phase 9 (VERIFY) is MANDATORY — if verification fails, fix before presenting to user
- Express mode still validates — auto-approve doesn't mean skip quality checks
- BA runs in ALL modes (Interactive asks questions, Express extracts from description)
Modes:
- Interactive (default): user reviews at each major phase gate
- Express: autonomous — user provides detailed description, reviews only final output

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.

scaffold is an agent published in the GitHub repository Rune-kit/rune (84 stars, last pushed 17d ago), licensed MIT. It adds 45 tokens to every session and 472 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 2026-08-30.

askit-quality-grader
Judges whether a skill triggers and behaves correctly by running it against its eval-set and grading the outputs. Use when delegating a behavioral evaluation - the opt-in LLM-judge role behind askit-evaluate's behavioral mode, distinct from the deterministic conformance core.
