absolute-spec

absolute-spec is a skill for Claude Code, Codex from maddhruv/absolute. It costs 122 tokens per session (2,265 once invoked), scanned A, original, MIT.

A lightweight design-spec workflow for turning a vague feature idea into a reviewed document. It scans the codebase, asks a small number of necessary questions, writes the result to docs/plans/, and stops before implementation.

In plain words
What is it for?
Use it to explore a feature on paper, prepare work for another developer or agent, and obtain an independent review of the proposed design.
Why use it?
It creates a clear handoff or discussion document before anyone commits to building the feature.

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

absolute-spec 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 4d 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.

Absolute Spec

Absolute Spec turns a fuzzy intent into a reviewed design-spec document — then stops. It is the planning artifact of work, lifted out of the full lifecycle: scan the codebase, ask only the questions the code can't answer, write the spec, run an independent scored review, and hand back a doc you can discuss, hand off, or feed into /absolute work to build.

It is deliberately lightweight. No relentless interview, no task board, no decompose, no execution. One deliverable: a spec good enough that an unfamiliar developer could build from it.


When to use this command

Use spec when:

  • You want a design spec to discuss, review, or hand off — not build right now.
  • You need to think a feature through on paper before committing to implementation.
  • A teammate or another agent will do the building from your spec.
  • You want a fast, reviewed design doc without the full phase-gated lifecycle.

Do NOT use spec when:

  • You want to design AND build in one flow → use /absolute work (spec is its Phase 2, followed by decompose + safe-wave execution).
  • You're documenting code that already exists / already shipped → use /absolute docs (reference/explanation docs, not a forward design).
  • The change is a one-line obvious fix needing no design.

The line vs work: spec produces a doc and stops; work produces a doc and then builds it. If you're unsure whether you'll build it now, start with spec — you can chain into work afterward and it will pick the spec up.


Key Principles

  1. Codebase before questions. Read what exists first; ask only what code can't answer.
  2. Bounded, not relentless. A short clarify pass (3–5 questions), not the depth-first grill work runs. Batching questions is fine.
  3. The spec is the deliverable. Quality matters more here than anywhere — keep the independent scored review.
  4. Reuse, don't reinvent. Template, scaling rules, and review rubric come from absolute-work's references/spec-writing.md. This command is the thin flow around them.
  5. Stop after review. No code, no board, no execution. Hand off cleanly.
  6. Never auto-commit. Write the spec file and report; the user commits.

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.
