code-distill

code-distill is a skill for Claude Code, Codex from pproenca/dot-skills. It costs 223 tokens per session (2,475 once invoked), scanned A, original, MIT.

A method for extracting implementation patterns from a specific GitHub codebase when no prepared guide exists for that library. It focuses on a narrowly defined subsystem or feature rather than the whole project.

In plain words
What is it for?
Use it to study focused topics such as a design system, composition, state management, effects, build setup, or routing in a named GitHub repository.
Why use it?
It helps answer how a real library solves a particular problem without relying on generic advice or an outdated reference.

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

code-distill 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 5d 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.

Code-Distill — Pattern Extraction Methodology for GitHub Codebases

Methodology distillation of the generic moves an agent makes when distilling code patterns on demand from a specific GitHub codebase, given a focused query. Not a per-library skill — one skill plus a thin per-library record in the shared knowledge graph (/knowledge/libraries/), because 90% of the work is the same regardless of which repo.

This is the dynamic light sibling of your static code-atlas distillations: opencode-ts, openai-codex-rust-patterns, nextjs-ppr-patterns. Those skills are heavy curated outputs — they distilled patterns from a single repo ahead of time. This skill is the on-demand alternative: when no static skill exists for the library yet, point at the repo and let the methodology run.

When to Apply

Use this skill when:

  • The user asks "how does <library> implement <feature>?" and points at (or names) a real GitHub repo
  • The query is focused on a single subsystem (design system, composition, state, error handling, effects, build, routing) — not "what is this whole codebase?"
  • No static code-atlas skill exists for the library yet (or the existing one is stale)
  • An ad-hoc invocation looks like /distill <library> <query> or "show me X in repo Y" in natural language
  • The library has too small a surface area, or too short a lifespan, to justify authoring a full static code-atlas distillation

This skill is NOT for:

  • Libraries with a static code-atlas skill — use opencode-ts, openai-codex-rust-patterns, nextjs-ppr-patterns, or other shipped per-library skills first. They are faster (already curated) and incorporate failure-gap lessons this skill cannot rediscover on demand.
  • Full-codebase architecture mapping — when the question is "what does this whole codebase do, by domain?", use codebase-comprehension-algorithms. That skill is the heavy algorithmic toolkit (Leiden, MoJoFM, SBM); this skill is focused-query extraction.
  • Authoring a full static code-atlas skill — the methodology playbook for that authoring task is a separate (not-yet-built) skill, the code-source sibling of library-reference-distillation. When you find yourself running code-distill against the same library more than ~3 times, that is the signal to graduate to a full static skill.
  • Documentation lookup — for "where do I find X in <library> docs?" use docs-search. This skill is for source code, not docs.
