What it does

Sip is an agent skill from LilMGenius/paperthin. After you create or change an artifact or skill, taste-test it with our own skills instead of trusting your in-session judgment — recursive self-improvement, made automatic. Use right after writing or editing anything, before calling it done, committing, or handing it off.

Its SKILL.md is about 760 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development. The repository describes itself as: Low-level agentic design patterns. Turning old engineering wisdom into reflexes your agent reaches for on its own—on any agent. The licence is MIT.

When your agent uses it

  • Development work in your project

Example prompts

  • “/sip”

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Spot the trigger: you just created or changed an artifact or skill and are about to call it done, commit, or hand it off.
  2. Cold-read it — run shower on the artifact (fresh-eyes comprehension / handoff check).
  3. Verify it's true — if the artifact asserts a reality-grounded claim, run factchk; if it defines an eval, metric, or experiment, run…
  4. Check consistency — run ssotize in audit mode across the repo for anything the change duplicated or contradicted; execute its…
  5. Detool portability claims — run detool only when the artifact claims portability, tool-neutrality, stack-agnostic durability, or…
  6. Tidy — re0 the changed docs so the result reads as a clean v0, not a patch over a draft.
  7. Apply the findings here, then serve it.

What it can do on your machine

Read from SKILL.md and the folder at commit 7d5dc62. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Sip loads about 761 tokens when it runs. Until then it costs about 69 tokens; SKILL.md has 423 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~69
When it runs · the whole SKILL.md, loaded when a task matches
~761

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
After you create or change an artifact or skill, taste-test it with our own skills instead of trusting your in-session judgment — recursive self-improvement, made automatic. Use right after writing or editing anything, before calling it done, committing, or handing it off.

Taste your own cooking: the moment you finish making something, check it with the very skills this repo ships before you serve it.

Goal

A reminder buried in docs ("remember to verify") won't reliably fire in a fresh session. sip makes the recursive self-improvement loop a triggered habit: right after any create or change, run our own skills on the result — the clean checks and the true ones — so quality doesn't ride on the author's biased in-session judgment.

Workflow

  1. Spot the trigger: you just created or changed an artifact or skill and are about to call it done, commit, or hand it off.
  2. Cold-read it — run shower on the artifact (fresh-eyes comprehension / handoff check).
  3. Verify it's true — if the artifact asserts a reality-grounded claim, run factchk; if it defines an eval, metric, or experiment, run mandela. Skip when it has neither.
  4. Check consistency — run ssotize in audit mode across the repo for anything the change duplicated or contradicted; execute its consolidation plan only after approval.
  5. Detool portability claims — run detool only when the artifact claims portability, tool-neutrality, stack-agnostic durability, or cross-agent reuse. Skip when it is provenance, operational notes, a tool-targeted runbook, or does not claim portability.
  6. Tidy — re0 the changed docs so the result reads as a clean v0, not a patch over a draft.
  7. Apply the findings here, then serve it.

Rules

  • Trigger on your OWN output, right after making it — that's when bias is highest and a check is cheapest.
  • Use the skills; don't re-implement them — shower for clarity, factchk/mandela for truth, ssotize for SSOT, detool for portability claims, re0 for cleanup. sip orchestrates and routes findings back to the author session to fix; the skills do the work.
  • Skip what plainly doesn't apply, or any check whose skill isn't installed — run only what's present. factchk/mandela fire only when there is a claim or an eval; detool fires only when the artifact claims portability, tool-neutrality, stack-agnostic durability, or cross-agent reuse; a one-line prose tweak may need only a consistency check. Say what you skipped and why.
  • Stop at the artifact — sip never touches git or makes commits.
  • Chain only model-invoked skills; a user-invoked skill (marked disable-model-invocation) is a human's to fire deliberately, so sip must not call one.

Verification

Before finishing:

  1. The change was actually run through the relevant skills, not eyeballed.
  2. Findings were applied (or consciously deferred with a stated reason).
  3. The artifact actually changed as a result (a diff exists), or every skipped skill has a stated reason.

Sip is an agent skill from LilMGenius/paperthin. After you create or change an artifact or skill, taste-test it with our own skills instead of trusting your in-session judgment — recursive self-improvement, made automatic.

When should I use Sip?

Sip fits situations like: development work in your project.

How do I install Sip in Claude Code?

Run `npx skills add LilMGenius/paperthin --skill sip -a claude-code`. Or copy the skill folder (skills/depth/sip in LilMGenius/paperthin) into .claude/skills/sip in your project. Claude Code loads it when a task matches its description.

How do I install Sip in Codex?

Run `npx skills add LilMGenius/paperthin --skill sip -a codex`. Or copy the skill folder (skills/depth/sip in LilMGenius/paperthin) into .agents/skills/sip in your project. Codex loads it when a task matches its description.

Can I use Sip in Cursor, Gemini CLI or GitHub Copilot?

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add LilMGenius/paperthin --skill sip -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/sip, .gemini/skills/sip, .github/skills/sip and .opencode/skills/sip in your project.

What does Sip need to run?

SKILL.md names no scripts, command-line tools or credentials: Sip is instructions for the agent only.

Does Sip access the network?

SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.

Is Sip safe to install?

Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.

What licence does Sip use?

Sip is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Sip use?

About 761 tokens (SKILL.md is roughly 3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Sip?

Skills that share tags, products or a category with Sip: Vercel Composition Patterns (supabase/supabase, 111k stars), Finishing a Development Branch (obra/superpowers, 296k stars), Typescript Advanced Types (rolling-scopes/rsschool-app, 10k stars) and PR Babysitter (openinterpreter/openinterpreter, 69k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Sip?
