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

postlake-accounts scanned grade A with 1 finding 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 6d 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.

What it actually says

PostLake: connected accounts

Returns each connected account's acc_… id, platform, handle, and health status. You only need this if you want to post to specific accounts by id. For most posts it's simpler to skip the lookup and post to a whole profile by name (see the postlake-publish skill). Handy here for checking which accounts are connected and whether any show status: "needs_reauth" (they need reconnecting before they can post).

Auth

All requests use a Bearer key from the POSTLAKE_API_KEY environment variable:

Authorization: Bearer $POSTLAKE_API_KEY

Get a key at https://app.postlake.dev/app/keys. Base URL: https://api.postlake.dev.

List connected accounts

curl https://api.postlake.dev/v1/social-accounts \
 -H "Authorization: Bearer $POSTLAKE_API_KEY"

Response:

{
 "accounts": [
  { "id": "acc_84a4…", "platform": "bluesky", "handle": "yourbrand.bsky.social", "status": "active" },
  { "id": "acc_e553…", "platform": "linkedin", "handle": "Your Name",       "status": "active" },
  { "id": "acc_54d8…", "platform": "instagram","handle": "yourbrand",       "status": "needs_reauth" }
 ]
}

Connecting new accounts

Connecting a platform is an OAuth flow a human completes in the browser. If a platform the user wants isn't listed, tell them to connect it at https://app.postlake.dev/app/channels, then re-list.

What platforms support

To check limits/options for a platform (character limits, media rules) before composing, call the public capabilities endpoint (no auth needed):

curl https://api.postlake.dev/v1/platforms/bluesky

Tips

  • Always resolve account ids from here rather than guessing.
  • Skip accounts with status: "needs_reauth" and tell the user to reconnect.

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.
