scaffold

A command for creating a new module or service by following a similar one already in the repository. A repository is the project's tracked source-code directory.

In plain words
What is it for?
Use it to create the files, entrypoint, build wiring, and smoke test for a new module, then build and test it.
Why use it?
It reduces inconsistency by copying the project's existing layout, build settings, tests, and operational conventions.

Token cost

What it costs to keep this loaded

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.

Security

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

Scaffold: $ARGUMENTS

  1. Find the closest existing sibling (another service/module of the same kind) and read its layout, build files, config wiring, tests, and observability setup. Mirror it — directory structure, naming, error handling, DI, telemetry.
  2. Create the new module with the same conventions: build/manifest files, a minimal working entrypoint, a passing smoke test, and the wiring needed to build alongside the rest of the repo.
  3. Build it and run its test to prove it compiles and passes. Use the language-appropriate engineer subagent (go-engineer / rust-engineer) for the implementation if it's substantial.

Report the files created and the build/test result. Don't wire it into production config (routing, ArgoCD apps) unless I ask.

Changes

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 a command published in the GitHub repository dshakes/compass (19 stars, last pushed 8d ago), licensed MIT. It adds 12 tokens to every session and 236 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 2026-08-30.
