Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00091 | $0.15114 |
| Opus 5.5 | $0.00036 | $0.06046 |
| Sonnet 5.5 | $0.00018 | $0.03023 |
| Haiku 4.5 | $0.00009 | $0.01511 |
Grade A, and why
zero-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 today.
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.
This is a copy
100% identical to zero-slop — 86 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 1,100 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Zero Slop
Local tool routing
In this plugin, run local checks through the declared zero-slop-local MCP
server. The examples below name its tools. Supply the contents of the named
drafts and packets using each tool's advertised input schema; never pass a file
path or run these examples through a shell. Example flags describe the matching
operation, not a command to execute. Save returned output only with the host's
approved file tools when the user requests a file.
Keep every editorial role and verification requirement below. A tool result
does not replace contextual reading or independent review. Learning still needs
affirmative consent, and activation needs separate consent. Use the version
tool with check_for_updates: true for the optional metadata-only release check.
Never call the remote editing tool automatically. If a local tool is unavailable,
use the documented manual path and disclose which checks did not run.
Do not delegate file conversion to other skills or execute shell commands, custom scripts, or conversion programs outside the declared MCP servers. For DOCX and PDF, use only built-in host file operations that support the format without launching custom code. If those operations are unavailable, leave the original file untouched, explain the format limitation, and ask the user to provide the prose or approve a plain-text alternative. Never claim that styles, layout, or the original format were preserved without producing that output.
A linter for the AI accent. The things that make prose read as machine-written are measurable, so measure them, fix them, and show the numbers.
Zero Slop is a skill, not an AI model. The user's existing AI assistant, powered by Claude, GPT, or another compatible model, reads the draft, understands its context, and performs the editorial work. The bundled local tools handle repeatable checks. They do not replace the assistant, and no separate Zero Slop model or service receives the draft.
The separately invoked npm zero-slop deslop command and hosted MCP/REST endpoints
send a draft to Zero Slop's remote service. They are opt-in alternatives, not local
checks in this workflow. Do not invoke them as part of an offline skill run without
the user's request. The npm score command continues to run locally.
What ships with it
60 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
