What it does

Common Product Requirements is an agent skill from HoangNguyen0403/agent-skills-standard. Standardize PRD discovery and drafting for product scope, user outcomes, requirement IDs, and acceptance criteria. Use when creating PRD, product requirements, feature specification, or acceptance criteria plan.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/evals.json`, `references/checklist.md` and `references/lean-spec-template.md`).

It sits in Product & Project Management, covering PRD writing and User stories. The repository describes itself as: A collection of Agent Skills Standard and Best Practice for Programming Languages, Frameworks that help our AI Agent follow best practies on frameworks and programming laguages. The licence is MIT.

When your agent uses it

  • Product requirements
  • Feature specification
  • Acceptance criteria plan

Example prompts

  • “/common-product-requirements”

Workflow steps

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

  1. Discovery Phase (Iterative)
  2. Drafting Phase (System of Record)
  3. Verification Checklist (Mandatory)

What it can do on your machine

Read from SKILL.md and the folder at commit b529c2d. 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

Common Product Requirements loads about 1.1k tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 60 tokens; SKILL.md has 429 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~60
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.5k

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.

Product Requirements Expert

Priority: P0 (CRITICAL)

Role: PM-owned product spec owner. Define the product "What" before technical design or implementation.

1. Discovery Phase (Iterative)

  • Context Injection: Ask for linked BRD objective and business success metric.
  • Gap Analysis: Identify missing info (problem, persona/JTBD, use cases, metrics, platform, flows, constraints, priorities, analytics, rollout, open questions).
  • Active Inquiry:
  • Ask 3-5 clarification questions at a time.
  • MUST provide (a, b, c) options to reduce user friction.
  • Example: "Target platform? a) Web b) Mobile c) Both"
  • Repeat: Continue until Actionable State reached.

2. Drafting Phase (System of Record)

  • Filesystem: Ensure docs/prd/ exists.
  • Load Template: Read references/prd-template.md.
  • Slug Alignment: Use the same [slug] from the source docs/brd/brd-[slug].md to maintain filename-level traceability.
  • Fill & Fix: Map Discovery answers to template. Mark unknowns as TBD.
  • Traceability: Assign stable REQ-* and AC-* IDs, and map each requirement to a BRD objective reference.
  • User Stories: Require specific persona, clear business value, and INVEST self-check.
  • Acceptance Criteria: Use Given/When/Then for behavior that could be misread; cover happy, edge, and negative paths.
  • Implementation Gate: Do not hand off to engineering until each slice names REQ-*, AC-*, owner, status, priority, and verification lane.
  • Handoff Quality: Name requirement owners, status, and define rollout/ops. Identify whether design-solution is required.
  • Readiness Route: Existing code without PRD/AC proof is partial/unverified; route through implementation-readiness.
  • Outcome Report: Include feature_status, requirement trace, completed/missing evidence, decision needed, and recommended next workflow.
  • Living Spec: Include analytics, risks, rollout, decisions, and changelog.
  • Output: Write to docs/prd/prd-[slug].md.

3. Verification Checklist (Mandatory)

  • Functional: all user flows defined?
  • Traceability: every AC mapped to REQ-* and business objective?
  • Non-Functional: Performance? Security? Offline mode?
  • Analytics/Ops: Events, guardrails, rollout, and support readiness?
  • Tech Constraints: DB schema impacts? API changes?
  • Edge Cases: Zero state? Error state?
  • Scope Hygiene: Out-of-scope items explicitly listed?

Anti-Patterns

  • No Assumptions: Never guess business logic. Ask.
  • No Vagueness: "Fast" -> "Load < 200ms".
  • No Implementation: PRD = "What", Implementation Plan = "How".
  • No Coding Before ACs: route missing ACs, owners, or RACI back to PM planning.
  • Offshore handoff: explicitly include a PM/BA/Engineering/QA RACI and name the validation owner before development starts.
  • No Orphan Requirements: every requirement must have owner, status, and linked objective.
  • No BRD/SRS Conflation: Route business-only items to BRD skill and technical-contract items to SRS skill.
  • No Generic Actors: replace "user" with a specific role or persona.

References

Ownership checklist

  • Record the Product owner, Engineering owner, and QA/release owner for every requirement or release decision.
