pragmatic-spec-validate

name	pragmatic-spec-validate
description	This skill should be used when the user asks to "validate a spec", "check if this spec is complete", "review the spec for completeness", "is this spec good?", "check the spec quality", "review this specification", "audit the spec", or wants a structured quality review of an existing specification document.

pragmatic-spec-validate

Validate a technical specification for completeness, clarity, and consistency.

Purpose

Run a structured review of a spec document and produce a PASS/WARN/FAIL report. Do not modify the spec — only report findings with actionable suggestions.

When This Skill Applies

Use this skill when a spec already exists and the user wants a quality assessment — regardless of whether implementation has started.

Do not use when:

• No spec exists yet → use pragmatic-spec-create
• The user wants to apply changes to an existing spec → use pragmatic-spec-update

Edge case: if the user says "review the spec" but also wants edits applied, clarify intent before proceeding: "Do you want a quality report only, or should I apply fixes as well?"

How to Validate a Spec

Step 0 — Language Detection

Infer the report language from the existing spec:

1. If the spec contains a Language: metadata field, use it
2. Otherwise, infer from the majority language of prose content in sections 2, 3, and 4 (Problem Statement, Goals, Proposed Solution) — if ≥80% of prose words are attributable to a single language, use that language
3. If the spec contains no prose (only tables and code blocks), or if no single language reaches the 80% threshold, treat as ambiguous and use AskUserQuestion:

In which language would you like the validation report to be generated?

1. pt-BR — Portuguese (Brazil)
2. es-ES — Spanish (Spain)
3. en-US — English (United States)
4. Other — specify which language

Record the chosen language and use it for all report content — section headings, check descriptions, notes, and recommended actions.

Step 1 — Locate and Read the Spec

Find the spec file. Common locations: docs/specs/, specs/, or the path provided. Read the full document before running any checks.

Step 1.5 — Pre-scan: Detect Open TODO Items

This is a mandatory step before running any checks.

After reading the spec in Step 1, count all [TODO: ...] occurrences across the document. If any are found, use AskUserQuestion to ask:

"I found N open TODO item(s) in this spec. These will result in WARN or FAIL findings. Would you like to:

1. Resolve them first with pragmatic-spec-update — for a cleaner validation report
2. Continue with validation as-is — TODOs will be reported as findings"

STOP. Wait for the user's choice before proceeding. If the user chooses to resolve TODOs first, end this skill and defer to pragmatic-spec-update.

Step 2 — Run Validation Checks

Evaluate each criterion below. Report PASS, WARN, FAIL, or N/A with a short explanation for each.

N/A may be used only for the checks listed below, under the stated conditions. All other checks must produce PASS, WARN, or FAIL.

Check	N/A condition
Non-goals defined	N/A if this is an exploratory spec where scope is intentionally open
Acceptance Criteria (≥2 testable)	N/A if this is a design-only spec with no implementation expected
No unresolved TODOs	N/A if the spec is explicitly in Draft status (TODOs expected)
Criteria are testable	N/A if the spec has no acceptance criteria (see row above)
Interface matches design	N/A if sections 6.1/6.2 are absent
Breaking changes flagged	N/A for brand-new features with no prior API surface
Security considerations addressed	N/A for purely internal tooling or non-networked features where security is genuinely not applicable
Single feature focus	N/A if the spec explicitly documents a bounded context that intentionally includes multiple related subsystems

Completeness

• Title & Status — Has a clear title and a defined status (Draft/Review/Approved)
• Problem Statement — Clearly describes the problem being solved
• Goals defined — At least one goal is stated
• Non-goals defined — Explicitly states what is out of scope (may be N/A — see table above)
• Proposed Solution — Describes the approach at a high level
• Acceptance Criteria — Has at least 2 testable acceptance criteria (may be N/A — see table above)
• No unresolved TODOs — No [TODO: ...] placeholders remain (WARN if present; N/A if spec is Draft — see table above)

Clarity

• Unambiguous language — No vague terms like "fast", "good", "easy" without measurable definitions
• Acronyms defined — All non-obvious acronyms are explained on first use
• Consistent terminology — Key terms are used consistently throughout

Consistency

• Criteria are testable — Each acceptance criterion specifies an actor, an action, and an observable result. FAIL if any criterion uses vague language ("the system should work correctly", "it should be fast") without measurable definitions. WARN if criteria are not in Given/When/Then format but are otherwise unambiguous. (may be N/A — see table above)
• Error/edge cases covered — At least one acceptance criterion addresses an error path, boundary condition, or edge case (not only happy path). (may be N/A — see table above)
• Interface matches design — If APIs/interfaces are defined, they align with the described behavior (may be N/A — see table above)
• No contradictions — Goals do not contradict the proposed solution or acceptance criteria

Technology Decisions

• Technology Decisions section present — Spec contains an explicit Technology Decisions table or equivalent section
• No implicit technology assumptions — Mentions of databases, queues, caches, or frameworks are backed by an explicit decision, not just assumed
• Undecided items flagged — Any [TODO: decide — options: ...] items are listed in Open Questions so they are visible and actionable
• Rationale captured — Each technology decision includes at least a brief reason (or references team convention / existing stack)

Technical

• Dependencies identified — External dependencies and integrations are listed
• Breaking changes flagged — Any breaking changes are explicitly noted (may be N/A — see table above)
• Security considerations addressed — Security implications are at least mentioned (may be N/A — see table above)

Scope

• Single feature focus — Section 7 (acceptance criteria) describes one cohesive feature. WARN if criteria span multiple independent user workflows with no shared data model or flow — such a spec is better split into separate documents. (may be N/A — see table above)

Step 3 — Generate Validation Report

Produce the report in this format:

## Spec Validation Report
**File:** <file path>
**Date:** <today>
**Overall Status:** PASS | WARN | FAIL

### Summary
- Passed:   X checks
- Warnings: X checks
- Failed:   X checks
- N/A:      X checks (not counted in totals above)

### Details
| Check | Status | Notes |
|-------|--------|-------|
| Title & Status | PASS | |
| Problem Statement | WARN | Section exists but is vague |
| Breaking changes flagged | N/A | New feature, no prior API surface |
| ... | | |

### Recommended Actions
1. <action item>
2. <action item>

Output Rules

• Print the full report; do not modify the spec file
• List FAILs first with concrete suggestions for each
• N/A checks are not counted in Passed/Warnings/Failed summary totals
• Overall Status is FAIL if any check is FAIL; WARN if any check is WARN and none are FAIL; PASS if all checks are PASS or N/A
• If all checks pass: summarize the spec's strengths instead of listing recommended actions
• If FAILs or actionable WARNs are present: end the report with an explicit recommendation to use pragmatic-spec-update to address them
• After a FAIL report: assert explicitly — "Do not use this spec as an implementation reference and do not share it with the team until FAIL items are resolved. Use pragmatic-spec-update to address them before starting implementation."
• After a WARN report: close with: "Spec can proceed to implementation. Consider resolving WARN items with pragmatic-spec-update before building. When ready, run pragmatic-spec-build against this spec."
• If a Single feature focus WARN is present: add: "Consider splitting this spec at [boundary] into separate specs — one per subsystem. A scoped spec produces a more precise pragmatic-spec-check report."
• After a PASS report: close with: "Spec is ready for implementation. Run pragmatic-spec-build against docs/specs/<feature-slug>.md to start."
