jules: Skill for Claude Code

.claude/skills/stop-slop/SKILL.md

stop-slop is a skill for Claude Code from jonathanmalkin/jules. It costs 66 tokens per session (1,346 once invoked), scanned A, original, MIT.

A review method for spotting writing patterns that make text sound machine-generated, such as repetitive structure, vague claims, artificial contrasts, and hidden responsibility.

In plain words
What is it for?
Auditing articles, social posts, and other content-pipeline drafts after they have been written and edited.
Why use it?
It helps make drafts clearer, more specific, and closer to natural human writing before publication.

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

stop-slop 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 6d 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 — 112 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stop Slop: Structural AI Pattern Audit

Eliminate structural AI writing patterns from prose. This skill focuses on paragraph-level and structural tells that survive word-level editing. Voice-Profile.md handles banned words/phrases. This handles the architecture of the writing.

When to Use

  • Content pipeline output (articles, Reddit posts, X threads) before publishing
  • As part of /write-article Stage 5 review panel
  • In content agent humanize mode as Pass 3 (structural audit)
  • Manual invocation via /stop-slop on any draft

Do NOT run on: Jules conversational output, internal docs, code comments, quick replies.

Core Rules

  1. Break formulaic structures. No binary contrasts ("Not X. Y."), negative listings, dramatic fragmentation, rhetorical setups. See references/structures.md.

  2. Kill false agency. Inanimate things don't perform human actions. "The complaint becomes a fix" = no. "The team fixed it" = yes. Name the human actor.

  3. Use active voice. Every sentence needs a subject doing something. No passive constructions hiding the actor.

  4. Be specific. No vague declaratives ("The reasons are structural"). Name the specific thing.

  5. Put the reader in the room. No narrator-from-a-distance. "You" beats "People." Specifics beat abstractions.

  6. Vary rhythm. Mix sentence lengths. Two items beat three. End paragraphs differently. No em dashes. No staccato fragmentation stacking.

  7. Trust readers. State facts directly. Skip softening, justification, hand-holding.

  8. Cut quotables. If it sounds like a pull-quote, rewrite it.

  9. No formulaic article structure. Don't default to: intro hook, context, 3-5 body sections, takeaway, CTA. Vary. No "Final thoughts" or "Key takeaways" headers. No rhetorical questions as section transitions.

Changes

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.
