scaffold-execution-plan

scaffold-execution-plan is a skill for Claude Code from avmnu-sng/sutra. It costs 32 tokens per session (2,588 once invoked), scanned A, original, MIT.

A planning scaffold for large software builds that span multiple work sessions. It creates a lasting structure for recording what to build, the order of work, and what counts as finished.

In plain words
What is it for?
Use it to organise independent pieces of a long build, resume work across sessions, and connect the plan to a workflow that coordinates implementation.
Why use it?
It prevents teams from losing their place or relying on memory when a project is too large to complete in one session.

Skill for Claude Code

Written for Claude Code: ${CLAUDE_PLUGIN_ROOT} variable.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

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-execution-plan 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 9d 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 — 262 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Scaffold execution plan

Lay down a durable, resumable structure for a build too large for one session, then wire in the build-orchestrator workflow that drives it. The structure is the source of truth across sessions: what to build next, in what order, and what "done" means for each unit of work.

This skill copies ready-made skeleton files that carry explicit TODO placeholders. It does not invent project specifics -- you (or a later planning pass) fill the placeholders against the real repo.

When to use

  • A build that plausibly spans many sessions or many days.
  • Work that decomposes into independent, shippable vertical slices.
  • Any effort where "where did we leave off?" is a real cost and resume must be mechanical, not from memory.

When not to use

  • A single-session change, a bug fix, or a one-slice feature. The overhead is not worth it.
  • A repo that already has an execution_plan/ tree. Read it and resume instead of re-scaffolding (see Resume below).

Preconditions

  • Run on a dedicated build branch or a worktree. NEVER scaffold or build on the default branch. Create the branch/worktree first.
  • Confirm the repo root and the local fast-check command before writing DEV_LOOP.md; if unknown, leave it as a TODO rather than guessing.

Step 0 -- adversarial pressure-test first

Before writing the plan, pressure-test the intended approach. The goal is to surface the failure modes that a naive plan silently regresses on, then encode each one as an explicit "do not regress" invariant in MASTER_PLAN.md.

Walk these prompts and write down every real delta:

  • Where does the naive slice ordering create a dependency cycle or force a big-bang integration at the end?
  • Which slices share hidden state (a schema, a config file, a global) so that finishing them in the wrong order corrupts the other?
  • What does each slice's acceptance criterion NOT catch? Name the class of bug that passes the criterion but breaks the system.
  • Which "we will handle it later" is actually load-bearing now?
  • What breaks under the real deployment/runtime conditions that a local run never exercises?

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.
