research-implement-feature

research-implement-feature is a skill for Claude Code from wanshuiyin/Auto-claude-code-research-in-sleep. It costs 120 tokens per session (8,079 once invoked), scanned A, original, MIT.

A software-building workflow for turning an underspecified “implement X” request into a working application. It records unclear design choices before writing dependent code, builds a basic end-to-end path first, then adds features.

In plain words
What is it for?
Use it when you want a coding agent to implement a feature without first conducting a long requirements interview. It helps structure the work, record decisions, and deliver the feature in successive steps.
Why use it?
It prevents hidden assumptions from shaping the code unnoticed and gives the implementation a usable path early. A separate review can look for decisions that were missed.

About the project

ARIS is a collection of Markdown-based skills that define a workflow for autonomous machine-learning research, including idea discovery, experiment automation, and review loops. Researchers and AI coding agents use it across tools such as Claude Code, Codex, Cursor, and OpenClaw without depending on a single framework. The catalogue entries are ARIS workflow skills and agents.

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

research-implement-feature 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 8d 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.

How it starts

The opening of the file, as written. The whole thing — 595 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Research Implement: Feature

Before each reviewer slot, follow Selectable Reviewers: resolve invocation → .aris/reviewer.json → Claude Code default (Codex MCP) with reviewer_route.py through the canonical helper resolver, preserving this slot's tier, fresh contexts, source/image inputs and deterministic gates. Codex examples/pins below apply only to backend=codex; other routes use their own first-call/reply contract. Save the route and actual returned identity; unavailable selections are REVIEW_UNAVAILABLE. Classify acceptance from actual families/completion/scope. Forward invocation reviewer/model/effort overrides to reviewer-bearing children. Generation workers are unchanged.

Build: $ARGUMENTS

This skill exists for one request shape — "just implement X for me" — where the user has a capability in mind, not an experiment plan, and does not want to be interviewed about it first.

It resolves that request the only honest way: stay autonomous, stop being silent. The skill never blocks to ask permission; it declares every decision the request left open, in a ledger, at the moment it makes it, and then a different model family goes looking for the ones it forgot to declare.

Two invariants

  1. Declare before you act. The instant a decision is under-determined by the request and changes an interface or a meaning, it gets a ledger row — before the code that depends on it exists. A ledger reconstructed at the end of the run is not a ledger, it is a changelog, and it systematically omits exactly the assumptions the author stopped noticing.

    Under ASK=semantic, this invariant strengthens to ask before you act for the semantic class: the ledger row is the unit of ambiguity, so a row that would have been written silently is a question that gets asked first.

  2. Spine before features. Rung F0 is a walking skeleton: the thinnest path from real entry point to real artifact, with stubs inside. It must run before any feature is added. Features are then added one rung at a time, each with its own acceptance check, each leaving every earlier rung green.

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.

research-implement-feature is a skill published in the GitHub repository wanshuiyin/Auto-claude-code-research-in-sleep (18,176 stars, last pushed 3d ago), licensed MIT. It adds 120 tokens to every session and 8,079 once invoked, about $0.0005 per session on Opus 5.5. 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 2026-09-16.
