spec

spec is a command for Claude Code from vignesh2027/AI-AGENT-SKILLS. It costs 0 tokens per session (109 once invoked), scanned A, original, MIT.

A command that loads instructions for writing a detailed specification before implementation begins. A specification describes what should be built, how success is measured, and the interfaces and data it needs.

In plain words
What is it for?
Use it to document stakeholders, success criteria, functional and non-functional requirements, data models, interface contracts, and open questions for a planned change.
Why use it?
It turns an informal feature request into testable requirements and surfaces unanswered questions before code is written.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 109 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe.
Origin original No closer match found in the catalogue.
Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

spec scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Load skills/spec-driven-development/SKILL.md and skills/requirements-analysis/SKILL.md.

Write a specification for the feature or change described. Follow the spec-driven-development process exactly:

  1. Capture the raw requirement
  2. Identify stakeholders and success criteria
  3. Write functional requirements (each independently testable)
  4. Write non-functional requirements
  5. Define the data model
  6. Define the interface contract
  7. List all open questions

Do not write any implementation code until the spec is complete and all open questions are resolved.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

spec is a command published in the GitHub repository vignesh2027/AI-AGENT-SKILLS (2 stars, last pushed 9d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 109 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
