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 | $0.00804 | $0.00804 |
| Opus 5.5 | $0.00322 | $0.00322 |
| Sonnet 5.5 | $0.00161 | $0.00161 |
| Haiku 4.5 | $0.00080 | $0.00080 |
Grade A, and why
scaffold AGENTS.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 1mo 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 — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Instructions
This repository does not use Beads for repo task tracking. Do not use the Beads CLI when working on Scaffold itself.
Quick Reference
make check # Run bash quality gates (lint + validate + test + eval)
make check-all # Run all quality gates (bash + TypeScript); full pre-push gate
git status -sb # Inspect local state quickly
git pull --rebase # Rebase onto latest remote state
git push # Publish local commits
Autonomous Review Cycles
docs/review-standards.md is the source of truth. Keep each MMR review cycle
to at most three rounds. A round-three reproducible in-scope or
required-safeguard blocker may start a new bounded cycle on the same PR only
after a concrete repair, focused regression proof, and the required gate pass.
Review the repaired exact head from round one. No owner approval is required
for this in-scope remediation. Stop immediately when the user asks to stop;
otherwise use only the evidence-backed stopping conditions in the source of
truth.
Do not restart for duplicate, stale, hypothetical, speculative, cosmetic, or already-dispositioned findings. Merge only after the final exact head meets the configured channel floor, required gates are green, every finding is dispositioned, and no verified blocker remains.
Scaffold Releases
When releasing Scaffold itself, follow docs/architecture/operations-runbook.md
instead of the generic /scaffold:release guidance.
- Update
CHANGELOG.mdandREADME.mdwhen user-facing behavior, install or upgrade steps, migration instructions, or command semantics changed. - Merge the release-prep commit/PR to
mainbefore tagging. - Tag merged
mainasvX.Y.Zand push the tag. - Create the GitHub release.
publish.ymluses BOTH the GitHub OIDC trusted-publisher config (provenance signing only) AND theNPM_TOKENrepo secret (the actual registry PUT). As of v3.28.0 the OIDC token alone does NOT authorize the publish — if npm publish fails with auth errors, fix theNPM_TOKENsecret per docs/architecture/operations-runbook.md §4.2a, not the trusted-publisher config.- Verify the
publish.ymlandupdate-homebrew.ymlworkflows succeeded so users can update vianpm update -g @zigrivers/scaffoldandbrew upgrade scaffold.
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.
