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 | $0.00133 | $0.03782 |
| Opus 5 | $0.00067 | $0.01891 |
| Sonnet 5 | $0.00027 | $0.00756 |
| Haiku 4.5 | $0.00013 | $0.00378 |
Grade A, and why
reddit-post-writer 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 7d 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.
This is a copy
100% identical to reddit-post-writer — 0 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 — 393 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Reddit Post Writer
Write Reddit posts and comments that earn upvotes by leading with genuine value. The affiliate recommendation comes second — after trust is built. Reddit users have a finely tuned spam detector. This skill helps affiliates write like Redditors, not marketers.
Stage
This skill belongs to Stage S2: Content
When to Use
- User wants to drive affiliate traffic from Reddit
- User wants to recommend a product in a relevant subreddit
- User is active in a community and wants to add a helpful product mention
- User has a genuine experience with a product and wants to share it naturally
- User asks how to participate on Reddit without getting banned for self-promotion
Input Schema
{
product: {
name: string # (required) "Notion"
description: string # (optional) What the product does
url: string # (optional) Affiliate link — used in disclosure only
reward_value: string # (optional) Commission — never revealed in post
}
subreddit: string # (optional) Target subreddit, e.g., "r/productivity"
post_type: string # (optional, default: auto) "post" | "comment_reply" | "ama_style"
trigger_question: string # (optional) Specific Reddit question or post you're replying to
personal_experience: string # (optional) Real experience with the product to use as anchor
audience: string # (optional) Who reads this subreddit — "students", "developers"
tone: string # (optional, default: "genuine") "genuine" | "analytical" | "casual"
problem_focus: string # (optional) The specific problem this post addresses
}
Workflow
Step 1: Understand Reddit Culture First
Before writing, confirm the target subreddit context. If subreddit is provided,
use web_search "reddit r/[subreddit] rules affiliate" to check:
- Are affiliate links explicitly banned? (many subreddits ban them outright)
- What post formats are most common? (links, text posts, discussions)
- What gets upvoted vs. downvoted in this community?
- Is there a community expectation of neutrality or personal experience?
What ships with it
1 file 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.
