specify

A design process for deciding how a software change should work before it is built. It records agreed choices in documents such as technical specifications, RFCs, or architecture decision records.

In plain words
What is it for?
Use it for feature planning, refactoring, migrations, public API or database changes, new modules, and other work that needs an agreed technical shape.
Why use it?
It clarifies requirements, tradeoffs, interfaces, and risks before code changes create conflicts or require rework.

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

specify 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 2d 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.

Specify

Iron Law

DESIGN-PARTNER MODE: READ THE SYSTEM, DECIDE THE SHAPE TOGETHER, THEN RECORD WHAT WAS AGREED.

When to Use

  • Feature work, refactors, migrations, or bug fixes that touch more than one contract, component, module boundary, state transition, or domain invariant.
  • Adding or changing a public surface: function signature, exported type, endpoint, event/queue payload, CLI flag, environment variable, config key, file format, or database schema/migration step.
  • Choosing shared project/package/module structure or a structural runtime dependency such as a framework, database, ORM, auth client, SDK, state library, or job queue.
  • Ambiguous or risky implementation intent where the agent should turn fuzzy goals into an approved design direction before code lands.
  • Significant new code with no caller-facing boundary: a substantial new module or component, new or rewritten non-trivial logic or an algorithm, or a deliberate change to observable behavior. Agree the plan or shape before implementing.
  • The user asks to design, specify, draft an ADR/RFC/tech spec, or capture a design note.
  • workflow chooses the Design-partner mode because architecture, domain modeling, caller-facing interfaces, cross-boundary contracts, or multi-component choices need human participation.

When NOT to Use

  • Typos, formatting, comment-only edits, or docs-only changes with no executable or contract effect.
  • Internal helper extraction with no caller-visible boundary.
  • Narrow bug fixes that restore intended behavior with no contract, state, data, or boundary change.
  • Pure dependency bumps with no public surface change.
  • Small local file moves or private implementation organization that does not establish a package/module boundary future work will depend on.
  • The user wants a concrete task plan after the design is already settled; use workflow or the harness planning mode instead.
  • A caller-facing interface is already concrete and only needs approval; use contract-first directly.

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

specify is a skill published in the GitHub repository kreek/consult (1 stars, last pushed 7d ago), licensed MIT. It adds 29 tokens to every session and 1,820 once invoked, about $0.0001 per session on Opus 5. 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.
