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.

SkillSpector: 4 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.01318 |
| Opus 5 | $0.00024 | $0.00659 |
| Sonnet 5 | $0.00010 | $0.00264 |
| Haiku 4.5 | $0.00005 | $0.00132 |
Grade B, and why
crosspost scanned grade B with 2 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 5d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
resp = requests.post( How it starts
The opening of the file, as written. The whole thing — 200 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Crosspost
Distribute content across multiple social platforms with platform-native adaptation.
When to Activate
- User wants to post content to multiple platforms
- Publishing announcements, launches, or updates across social media
- Repurposing a post from one platform to others
- User says "crosspost", "post everywhere", "share on all platforms", or "distribute this"
Core Rules
- Never post identical content cross-platform. Each platform gets a native adaptation.
- Primary platform first. Post to the main platform, then adapt for others.
- Respect platform conventions. Length limits, formatting, link handling all differ.
- One idea per post. If the source content has multiple ideas, split across posts.
- Attribution matters. If crossposting someone else's content, credit the source.
Platform Specifications
| Platform | Max Length | Link Handling | Hashtags | Media |
|---|---|---|---|---|
| X | 280 chars (4000 for Premium) | Counted in length | Minimal (1-2 max) | Images, video, GIFs |
| 3000 chars | Not counted in length | 3-5 relevant | Images, video, docs, carousels | |
| Threads | 500 chars | Separate link attachment | None typical | Images, video |
| Bluesky | 300 chars | Via facets (rich text) | None (use feeds) | Images |
Workflow
Step 1: Create Source Content
Start with the core idea. Use content-engine skill for high-quality drafts:
- Identify the single core message
- Determine the primary platform (where the audience is biggest)
- Draft the primary platform version first
Step 2: Identify Target Platforms
Ask the user or determine from context:
- Which platforms to target
- Priority order (primary gets the best version)
- Any platform-specific requirements (e.g., LinkedIn needs professional tone)
Step 3: Adapt Per Platform
For each target platform, transform the content:
X adaptation:
- Open with a hook, not a summary
- Cut to the core insight fast
- Keep links out of main body when possible
- Use thread format for longer content
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.
- 5d ago First seen · 200 lines · 49 tokens per session scan B fca10db4980d
crosspost is a skill published in the GitHub repository loulanyue/awesome-claude-notes (270 stars, last pushed 5d ago), licensed MIT. It adds 49 tokens to every session and 1,318 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
