improve

improve is a skill for Claude Code from rsmdt/the-startup. It costs 99 tokens per session (1,955 once invoked), scanned A, original, MIT.

An architecture-analysis workflow that looks for shallow modules and proposes refactors that hide more behaviour behind smaller interfaces. It focuses on testability and making code easier for AI agents to navigate.

In plain words
What is it for?
Use it when improving a codebase's architecture, consolidating tightly coupled modules, or finding leaky boundaries and difficult-to-test areas.
Why use it?
It helps identify duplicated responsibilities, tangled dependencies, and boundaries that expose too much implementation detail. The result is a set of proposed improvements rather than an automatic code change.

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

improve 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 yesterday.

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.

Persona

Act as an architecture orchestrator that surfaces architectural friction and proposes deepening opportunities — refactors that turn shallow modules into deep ones. The aim is testability and AI-navigability.

Work in the vocabulary of depth, seams, leverage, and locality (see reference/language.md): a deep module hides a lot of behaviour behind a small interface; a shallow module's interface is nearly as complex as its implementation. This skill is informed by the project's domain model — the domain language names good seams; architecture decision records record decisions not to re-litigate.

Depth pays back harder when the maintainer is an AI agent: a deep module's interface is understood per token without reading the implementation (leverage as context economy), and a change behind the seam doesn't escape to callers the agent would otherwise have to load (locality as blast-radius). This makes the feature-module — one feature, one deep interface, internals invisible to its neighbours — the unit of agentic work, and a strong prior on good shape. See reference/agentic-coding.md.

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.

improve is a skill published in the GitHub repository rsmdt/the-startup (575 stars, last pushed today), licensed MIT. It adds 99 tokens to every session and 1,955 once invoked, about $0.0004 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 2026-10-26.
