aid-prototype

aid-prototype is a skill for Claude Code from AndreVianna/aid-methodology. It costs 141 tokens per session (1,478 once invoked), scanned A, original, MIT.

A throwaway prototype builder for trying a product or technical direction before committing to a full implementation.

In plain words
What is it for?
Use it for low-fidelity models, runnable technical experiments, and other isolated feasibility checks.
Why use it?
It lets you test whether an idea works and capture evidence without treating the experiment as production work.

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

aid-prototype 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 26d 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.

Prototype (validate a direction, throwaway)

/aid-prototype builds a throwaway model now to de-risk a direction, captures the validation signal, presents it, and hands the real build off. It resolves nothing and its output is not production. For a design you intend to keep and build, use /aid-design. Deeper per-slot guidance: .aid/runtime/templates/shortcut-scaffolding/prototype.md.

  • Not a numbered pipeline phase; does not route to /aid-execute.

State machine: INTAKE -> BUILD -> VERIFY (light) -> PRESENT [user decides] -> HANDOFF? -> DONE. Print the [State: NAME] -- {purpose} entry line on each state.


State: INTAKE

  1. Require a direction. Empty argument -> ask one bootstrapping question ("What direction do you want to validate, and what would tell you it works?") and wait.
  2. Capture (thin): direction/hypothesis; fidelity (paper | low-fi | runnable spike, default low-fi); the success signal that would validate it; the scope boundary (what it does NOT attempt -- keeps it throwaway).
  3. Pick the path: Fast -- a clear direction + success signal -> build now. Guided -- vague ("prototype something for onboarding") -> scope direction / success signal / fidelity first.
  4. Classify complexity (model + effort): simple -> aid-architect at sonnet / medium; complex (a runnable spike, a rich flow) -> opus / high.
  5. Consult the Work Initiation Gate, then allocate the work folder + STATE. First run the gate (.aid/runtime/templates/work-initiation-gate.md): bash .aid/runtime/scripts/works/enumerate-works.sh (main tree + every git worktree). Empty -> allocate, no prompt. Works exist -> ask new-vs-continuation; on continuation route to the chosen work's resume door and STOP (allocate nothing); on new work: create and enter the worktree per the gate's § 3a step 2 (worktree-lifecycle.sh create <work-id> <name>, STOP on a non-zero exit or empty path, else enter the resolved path), then allocate (pipeline.path: lite, initiator: aid-prototype, lifecycle: Running, active_skill: aid-prototype; phase not driven). For a runnable spike, associate an opt-in git worktree so the throwaway code is isolated.

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.
