sip

sip is a skill for Claude Code, Codex from LilMGenius/paperthin. It costs 55 tokens per session (702 once invoked), scanned A, original, MIT.

A self-review workflow for add-ons and other artifacts after they are created or changed. It uses the project's own checking skills to test clarity, factual claims, consistency, and portability when relevant.

In plain words
What is it for?
Use it after editing a skill or artifact to run a fresh-eyes review, fact check reality-based claims, audit repeated content, and review portability claims.
Why use it?
It helps catch misunderstandings, unsupported claims, duplicated information, and portability problems before work is handed off.

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

sip 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 4d 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 — 37 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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. Tidyre0 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.

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.
