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 | $0.00062 | $0.01236 |
| Opus 5 | $0.00031 | $0.00618 |
| Sonnet 5 | $0.00012 | $0.00247 |
| Haiku 4.5 | $0.00006 | $0.00124 |
Grade A, and why
anti-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 12d 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 — 144 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Anti-Slop Writing Rules
Apply before writing any KB document, synthesis, analysis, report, or technical documentation. These rules govern written artifacts, not chat.
Structural rules
Start with content. First sentence delivers the fact, claim, or decision. No "In this document we will explore...", no "This analysis covers...", no "It is worth noting that...".
No concluding recap. Final paragraph must add new information or be absent. Never restate what was just written.
Active voice. "The algorithm reduces latency" not "Latency is reduced by the algorithm."
One idea per sentence. Split compound sentences. Short is readable; long is a symptom.
Every word earns its place. Read the draft. Delete any sentence that could be removed without losing information.
Slop patterns — detect and cut
Confidence theater
Hedging on things that are simply true or false.
- Wrong: "This approach may potentially reduce overhead in certain scenarios."
- Right: "This approach reduces overhead when the input is sorted."
Fix: state the fact directly. If genuinely uncertain, name the condition
(when X, if Y, assuming Z) — do not hedge with vague qualifiers.
False enumeration
Turning a 2-item answer into a 5-bullet list for appearance of thoroughness.
- Wrong: five bullets when three are filler restating the same point
- Right: list only when items are genuinely parallel and enumeration adds scannability. Prose is often clearer for 2–3 items.
Fix: ask "would this be clearer as one sentence?" If yes, write one sentence.
Balance theater
Adding a counterpoint to seem fair when one position is correct.
- Wrong: "While approach A has merits, approach B also has its advantages..." (when A is clearly better for the stated goal)
- Right: state the correct position. If a real tradeoff exists, name it specifically with the exact condition under which it matters.
Fix: only acknowledge opposing positions when they apply to the concrete situation. Generic balance is noise.
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.
- 12d ago First seen · 144 lines · 62 tokens per session scan A b28cc57ccf0c
anti-slop is a skill published in the GitHub repository geronimo-iia/agent-skills (2 stars, last pushed 11d ago), licensed MIT. It adds 62 tokens to every session and 1,236 once invoked, about $0.0003 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 2026-08-31.
