Lightweight standalone design spec for AI coding agents: codebase scan → bounded clarify pass (3–5 questions, not a grill) → reviewed design doc written to docs/plans/ → independent scored review → stop. No task board, no build. Use when you want a spec to discuss, hand off, or review before committing to implementation. Chains into absolute-work when ready to build.

Lightweight standalone design spec for AI coding agents: codebase scan → bounded clarify pass (3–5 questions, not a grill) → reviewed design doc written to docs/plans/ → independent scored review → stop. No task board, no build. Use when you want a spec to discuss, hand off, or review before committing to implementation. Chains into absolute-work when ready to build. Triggers on "absolute spec", "write a spec", "spec out this feature", "draft a design doc", "I want a spec to hand off / review, don't build it yet".
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
Codebase before questions. Read what exists first; ask only what code can't answer.
Bounded, not relentless. A short clarify pass (3–5 questions), not the depth-first
grill work runs. Batching questions is fine.
The spec is the deliverable. Quality matters more here than anywhere — keep the
independent scored review.
Reuse, don't reinvent. Template, scaling rules, and review rubric come from
's . This command is the thin flow around them.
absolute-work
references/spec-writing.md
Stop after review. No code, no board, no execution. Hand off cleanly.
Never auto-commit. Write the spec file and report; the user commits.
The Flow
SCAN ─→ CLARIFY ─→ WRITE ─→ REVIEW ─→ HANDOFF
No hard gates between steps (that's work). The one checkpoint is the clarify pass —
ask, get answers, then proceed straight through to a reviewed spec.
Step 1 — SCAN
Ground the spec in reality before asking anything.
Convention detection — read cached config first: if .absolute.config.json or
~/.absolute/config.json exists (from /absolute init), resolve the effective config
(project file → global projects["<cwd>"] → global defaults) and use its conventions,
detecting only what's missing. No config → soft-suggest init and run work's Codebase
Convention Detection table (package manager, language/runtime, test runner, linter, build
system, directory conventions; see absolute-work's SKILL.md under Codebase Convention
Detection). The spec must speak the project's real stack, scripts, and paths.
Deep context scan — read what exists: docs/ (README first), root README.md,
CLAUDE.md, CONTRIBUTING.md, docs/plans/ (overlapping/related designs), recent
commits (last 10–20), package manifests, and the directories the feature touches.
Synthesize — state what you learned in 2–4 lines (stack, relevant existing code,
any overlapping prior design). Do not dump a file listing.
Detect the work type (feature / refactor / greenfield / migration) only enough to
shape the spec — spec does not run the full per-type question banks.
Step 2 — CLARIFY (bounded pass)
Ask only the questions the codebase genuinely cannot answer — the preference and
scope forks. Cap at 3–5 questions; batching is allowed (one AskUserQuestion call
with multiple questions where available).
Good questions to ask (when code can't answer them):
Scope boundary — what's in v1 vs explicitly deferred.
Behavior forks — real-time vs batch, sync vs async, the genuine "which way" decisions.
Data/contract shape — only where the design hinges on it and code gives no signal.
Non-goals — what this explicitly will NOT do.
Do NOT ask: anything a config, manifest, test file, or existing pattern already states.
When the code answers it, say so in the spec instead of asking.
If the user said "no questions, just draft it" — skip to WRITE and capture every guess
in an ## Open Questions / assumptions section instead.
Step 3 — WRITE
Write the spec to <specDir>/YYYY-MM-DD-<topic>-design.md (<topic> = short kebab-case
slug). <specDir> is preferences.specDir from config when present, else docs/plans.
Use the template, section-scaling rules, writing style, and Decision Log format
from absolute-work's references/spec-writing.md — that file is the single source of truth;
do not restate it here, load it. In particular:
Pick the complexity tier (Simple / Medium / Complex) using the complexity
heuristic table, and scale sections accordingly. Remove sections that would only say
"N/A".
Be concrete: real file paths, real endpoints, real schemas in code blocks — never
"an endpoint for X".
Fill the Decision Log with the forks resolved in CLARIFY plus any you recommended,
each with a one-line rationale.
Step 4 — REVIEW (scored, independent)
Dispatch a separate reviewer subagent — the agent that wrote the spec does not grade
it (generator ≠ evaluator). Use the rubric and reviewer prompt template verbatim from
absolute-work's references/spec-writing.md (Scored Spec Review Protocol): graded on
Completeness, Consistency, Clarity, Scope, Testability (1–5 each, weighted).
Weighted Score
Verdict
Action
4.0 – 5.0
Approved
Proceed to HANDOFF
3.0 – 3.9
Needs Work
Fix the flagged issues, re-dispatch (max 3 iterations)
< 3.0
Major Gaps
Surface to the user immediately; do not silently iterate
Reviewer approval is necessary but not the end — the user still has the final say at
HANDOFF.
Step 5 — HANDOFF
Present — the spec path, the complexity tier, and the reviewer's weighted score +
verdict. Summarize the key decisions in 2–4 lines.
Offer to build — chain into /absolute work, which will pick up the spec at
its decompose phase rather than re-running intake. Make this an explicit, optional
next step.
Stop. No code, no board. Never run git commit — suggest a message if asked;
the user commits.
Gotchas
Drifting into work. If you start decomposing into tasks or writing code, you've
left spec. Stop at the reviewed doc.
Asking what the code answers. The bounded pass is for preferences and forks only —
scan first, ask second.
Skipping the review to "stay light". The review is the cheap quality gate that
makes a standalone spec trustworthy. Keep it.
Restating spec-writing.md. Load it; don't copy the template/rubric in here —
two copies drift.
Over-asking. More than ~5 questions means you're running work's interview. Tighten.
Output / Response Style
Respond terse like smart caveman. All technical substance stay. Only fluff die. Drop
articles, filler, pleasantries, hedging. Fragments OK. Technical terms exact. Code blocks
and quoted errors unchanged. Drop caveman for security warnings, irreversible-action
confirmations, and any multi-step sequence where fragment order risks misread; resume
after. Spec prose itself is written normally (it's a deliverable, not chat).
Companion commands
Sibling commands in this skill chain naturally around spec:
/absolute work — build what the spec describes (picks the spec up at decompose).
/absolute ui — design the interface for a feature the spec defines.
/absolute docs — once it's built and shipped, document it for readers.
Suggest them where relevant; they're always available (same skill, no extra install).
