paoding-skill

A guide for studying and reviewing packages of instructions for AI coding agents, including skill files and workflow playbooks.

In plain words
What is it for?
Reverse-engineering, comparing, reviewing, or learning design patterns from AI-agent skills and instruction packages.
Why use it?
It helps turn complicated agent instructions into clear notes about their behavior, safeguards, reusable ideas, and unnecessary complexity.

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

paoding-skill 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.

Purpose

Turn a skill package into useful creator notes. Explain how the skill changes an agent's behavior, what bad output it prevents, which parts are worth copying, and which parts are too heavy for the job.

Default to the smallest useful output. A web handbook is an output mode, not the identity of this skill.

Start Here

  1. Map the source package first.
  2. Choose the output mode from the user's request:
    • Review / keep-cut advice: write a direct Markdown review.
    • Pattern extraction: write human notes and optional JSON/YAML.
    • Web handbook / 解剖手册: read references/handbook-spec.md, then references/web-production-flow.md.
  3. Load only the companion reference needed for the current section. Examples are calibration only; references and source files are the contract.

Workflow

1. Map the Package

Treat the input as a single SKILL.md, a skill directory, or a folder of skills.

  • Find every SKILL.md.
  • Note references/, scripts/, assets/, examples/, tests/, and metadata.
  • Read the entry SKILL.md first.
  • Read referenced files only when they explain the skill's design.
  • Inspect scripts to see which fragile jobs they take away from the agent — and run every script that has a valid in-package input (mandatory; see 可执行工件必跑 in references/evidence-collection.md).

For a batch, analyze representative skills first, then scan the rest for repeated structures.

2. Find the Real Task Pain

Read references/pain-dimensions.md, then run its item-driven sweep:

  1. Imagine doing the task bare (a human novice, then a default agent) and list where each would fail.
  2. Inventory every rule, script, intermediate artifact, and checkpoint in the package. List the intermediate artifacts completely.
  3. Run each item through the three-question pain test (counterfactual, baseline, evidence grade) and tag it with one of the seven dimension labels.
  4. Reconcile: pains the skill catches that you missed, pains you expected that it ignores (blind spots), and residue that fits nowhere.

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.

paoding-skill is a skill published in the GitHub repository longyunfeigu/paoding-skill (24 stars, last pushed 2mo ago), licensed Apache-2.0. It adds 105 tokens to every session and 2,269 once invoked, about $0.0005 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 2026-08-30.
