Techniques for writing clear product specifications, user stories, and acceptance criteria.

  • Works in 2 steps: Solution Masquerading as Problem → Missing Acceptance Criteria
  • Defining feature requirements
  • SKILL.md covers Overview, When to Use This Skill, Product Requirements Documents… and User Stories, plus 8 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Specification Techniques is an agent skill from slgoodrich/agents. Techniques for writing clear product specifications, user stories, and acceptance criteria. Use when defining feature requirements, writing user stories, creating acceptance criteria, or reducing spec ambiguity. Trigger on: 'write a spec', 'acceptance criteria for this feature', 'user story format', 'define requirements', 'Given-When-Then'.

Its SKILL.md is about 3.3k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including reference files and assets (for example `assets/edge-case-checklist.md`, `assets/job-story-template.md` and `assets/non-functional-requirements-template.md`).

It sits in Product & Project Management, covering User stories and PRD writing. The repository describes itself as: AI PM Workflows for Claude Code.

When your agent uses it

  • Defining feature requirements
  • Writing user stories
  • Creating acceptance criteria
  • Reducing spec ambiguity

Example prompts

  • “write a spec”
  • “acceptance criteria for this feature”
  • “user story format”
  • “/specification-techniques”

Workflow steps

2 steps, taken from the step headings in SKILL.md.

  1. Solution Masquerading as Problem
  2. Missing Acceptance Criteria

What it can do on your machine

Read from SKILL.md and the folder at commit 3b5835b. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Specification Techniques loads about 3.3k tokens when it runs, and up to ~26k if it reads all its reference files. Until then it costs about 92 tokens; SKILL.md has 1,005 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~92
When it runs · the whole SKILL.md, loaded when a task matches
~3.3k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~26k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SKILL.md

Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 1,005 words (~3,256 tokens).

“Structured methods for translating product vision into clear, actionable requirements that align teams, reduce ambiguity, and enable successful execution.”
