scoping

scoping is a skill for Claude Code, Codex from lantisprime/claude-sdlc. It costs 0 tokens per session (451 once invoked), scanned A, original, MIT.

A scope-clarification guide for turning vague development requests into specific, testable work.

In plain words
What is it for?
It helps clarify bugs, feature requests, affected users, environments, success criteria, and out-of-scope work before planning or coding.
Why use it?
It prevents guessing, misunderstandings, and extra work caused by unclear requirements.

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

scoping 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 3d 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

Scoping

Turn a vague ask into something a plan can be written against.

When to trigger

Proactively, whenever the request is missing any of:

  • Trigger condition (when does this happen / when should it happen?)
  • Expected behavior
  • Actual behavior (for bugs)
  • Specific user flow or entry point
  • Environment (dev / staging / prod)
  • Measurable success criteria

Don't guess. Claude's guesses become scope creep later.

The clarification checklist

Ask only the questions whose answers aren't already clear. Typical set:

  1. What is the user trying to do? (business outcome, not technical symptom)
  2. What happens now? (current behavior, reproduction steps if a bug)
  3. What should happen? (target behavior with acceptance criteria)
  4. Which users or flows? (scope of impact)
  5. Which environment? (local, staging, prod)
  6. How will we know it's done? (test or observation)
  7. What's explicitly out of scope? (prevents "while you're at it")

Output

Append the clarified scope to the plan artifact under a Clarifications section. If no plan exists yet, create one via the plan skill using the clarified inputs.

What this skill must NOT do

  • Do not fill in ambiguous fields with plausible-sounding defaults.
  • Do not ask every question every time — only the ones not already answered.
  • Do not proceed to Plan until the blocking ambiguities are resolved.

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.

scoping is a skill published in the GitHub repository lantisprime/claude-sdlc (3 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 451 tokens. 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 2026-08-31.
