Automated summary

Pairs requirements and issue acceptance criteria with acceptance-level validation, closing the top of the V cycle for a feature or release slice.

Strengths

  • Maps every acceptance criterion to a concrete validation method: automated check, scripted test, manual checklist, or monitored metric
  • Enforces testable acceptance criteria, ideally with copy-pasteable steps
  • Reuses validation drafting and detailing skills to derive scenarios once behaviour is known
  • Suggests forward references to existing requirement clauses instead of duplicating prose

Limitations

  • Assumes well-formed requirements and acceptance criteria already exist upstream
  • Provides no automation tooling; executing the validations is still manual work
  • Of little use outside a requirements-driven workflow or when no requirements documentation exists
When to use it

Use when writing or refining an issue so each acceptance criterion maps to observable evidence, or when preparing a stakeholder demo, UAT, or audit trail.

When not to use it

Avoid for exploratory tasks or one-off fixes with no formalized requirements or acceptance criteria to validate.

Security analysis

Safe
Quality score85/100

This is a documentation-only process skill with no declared tools or executable instructions. It describes linking requirements to acceptance criteria and validation methods, with no destructive, exfiltration, obfuscation, or safety-disabling behavior.

How this analysis is made

Examples

Map AC to validation
Take the acceptance criteria in issue #142 and, for each one, name the validation method (automated test, scripted check, manual checklist, or metric) and flag any criterion that isn't testable yet.
Harden mushy criteria
Review our feature ticket and rewrite vague acceptance criteria like 'works well' into measurable or binary checks, keeping a single canonical statement of intent and linking to the requirements doc instead of copying it.
Prepare UAT evidence
Build the acceptance-level validation plan for the current release slice: list each goal from the requirements doc, its linked acceptance criteria, and the evidence we'll show stakeholders during UAT.

V-model: requirements ↔ acceptance

Links left: requirements (2.x) and well-formed issue-acceptance-criteria with right: acceptance-oriented validation (8.x).

When to use

  • Defining or refining an issue so each AC maps to observable evidence.
  • Preparing stakeholder demo, UAT, or audit evidence for “what we said we would deliver.”

Instructions

  1. Ensure acceptance criteria are testable (copy-pastable steps where possible).
  2. For each AC, name the validation method: automated check, scripted test, manual checklist, or monitored metric.
  3. Use validation-draft to derive scenarios; refine with validation-detail once behaviour is known.
  4. If requirements docs exist (goals, constraints, scope from 2.x), add explicit forward references from AC to those clauses where helpful.

Pitfalls

  • Duplicate prose: keep one canonical statement of intent; link instead of copying long specs into both issue and docs.
  • Mushy AC: “works well” → replace with measurable or binary checks.

From the file to a first result

The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.

View the source and supporting files

This download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.

1. Download the file

Download SKILL.md

From the root of a test project, save the file as .skill-downloads/v-model-requirements-acceptance-criteria-mrx3xyw4/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.

Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.

mkdir -p '.skill-downloads/v-model-requirements-acceptance-criteria-mrx3xyw4' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/v-model-requirements-acceptance-criteria-mrx3xyw4/download' --output '.skill-downloads/v-model-requirements-acceptance-criteria-mrx3xyw4/SKILL.md.part' && mv '.skill-downloads/v-model-requirements-acceptance-criteria-mrx3xyw4/SKILL.md.part' '.skill-downloads/v-model-requirements-acceptance-criteria-mrx3xyw4/SKILL.md'

2. Check prerequisites

Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.

No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.

The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.

3. Load the skill

After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

Official OpenSkills installation
openskills install './.skill-downloads/v-model-requirements-acceptance-criteria-mrx3xyw4'

openskills read 'v-model-requirements-acceptance-criteria-mrx3xyw4'

Reading should display the installed file content and its base directory. It does not run the skill or install its dependencies.

For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.

openskills sync

Manual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.

4. Try a first task

Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:

Read .skill-downloads/v-model-requirements-acceptance-criteria-mrx3xyw4/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.

Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
