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

post-today 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 4d 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 — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Post Today

Post today's approved content to X, auto-reply with {{WEBSITE_URL}} link, and stage crosspost drafts.

Trigger

User invokes /post-today or says "post it", "publish today", "send the post", "go live"

Prerequisites

  • Today's X copy must exist at content-engine/output/[week]/[day]/x-copy.md
  • Content must have passed /content-qa (check for QA report or run it now)
  • Banner must exist at content-engine/output/[week]/[day]/banner.png (or video.mp4)

If prerequisites aren't met, tell the user what's missing and stop.

Steps

1. Load today's content

Detect today's day name. Read the X copy, banner path, and any LinkedIn copy from the output folder.

Run /content-qa if no QA report exists for today. Block on FAIL.

2. Final confirmation

POSTING TO X
════════════════════════════════════════
Copy ([char count]/280):
[the post text]

Media: [banner.png / video.mp4]
════════════════════════════════════════
Post now? (yes/edit/cancel)

3. Post to X

Post the approved copy to X using whichever channel the user has wired:

  • If an X/Twitter MCP is installed: call its post tool with the copy text and media path.
  • Otherwise: present the copy + media in a final confirmation block and ask the user to post it manually from their X client, then paste the resulting tweet URL back.

Capture the tweet ID from the returned URL — you need it for Step 4 and for /reply-monitor.

4. Auto-reply with link

Wait 10 seconds, then reply to the posted tweet with {{WEBSITE_URL}}:

  • MCP path: call the post tool with reply_to=<tweet_id> and body {{WEBSITE_URL}}.
  • Manual path: prompt the user to reply with the link and confirm once done.

5. Stage crosspost drafts

If LinkedIn copy exists in the output folder, present it:

CROSSPOST STAGED
════════════════════════════════════════
LinkedIn ([char count]/3000):
[linkedin copy]

Post to LinkedIn manually in 30-60 min.
════════════════════════════════════════

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.
