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 | $0.00093 | $0.00911 |
| Opus 5.5 | $0.00037 | $0.00364 |
| Sonnet 5.5 | $0.00019 | $0.00182 |
| Haiku 4.5 | $0.00009 | $0.00091 |
Grade A, and why
get-started 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 24d 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 — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Get started with PostFast
These steps check the PostFast connection and take the user to their first post. They only read, apart from a connect link the user asks for. Scheduling, comments, repurposing and reports have their own skills: schedule-posts, manage-comments, repurpose-content and performance-report.
Rules
- Read first, change nothing. Setup uses tools that only read. The one exception is
generate_connect_link, and only when the user wants a link to connect or reconnect an account. - Report what the tools return. Don't guess which accounts are connected, and mention the ones that are not.
- Keep it short. Show what the next step needs, then offer it.
Steps
1. Check the connection
Call list_workspaces.
- It answers: PostFast is connected. Carry on.
- The PostFast tools are missing, or the call says the user is not signed in or the sign-in expired: PostFast is not connected in this app yet, or its sign-in lapsed. Ask the user to add or reconnect PostFast in their app's connector or app settings and sign in with their PostFast account. While signing in they choose the workspace this connection uses by default. Then try again.
- They have no PostFast account: say that PostFast works with an existing PostFast account and that they need one to use it here. Don't link to sign-up, plans or pricing.
2. Pick the workspace
list_workspaces shows every workspace this connection can use. With one, carry on. With several, show them by name and ask which to work in, then pass its id as workspaceId on every call that follows. Leaving workspaceId out uses the workspace chosen at sign-in.
3. See the connected accounts
Call list_accounts and list the accounts by network, with each one's platformUsername or displayName.
- CONNECTED accounts can publish.
- DISABLED accounts won't publish until they are reconnected. Give the
disabledReasonand offer a reconnect link:generate_connect_linkwithplatformsset to that network. Whoever owns the account opens the link and signs in again. SetsendEmailonly when the user asks you to email the link and gives the address. - No accounts: nothing is connected in this workspace yet. The user connects accounts in the PostFast app (https://app.postfa.st) or sends a link from
generate_connect_linkto whoever owns them. inboxCapableshows which accounts' comments reach the PostFast inbox.
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.

get-started is a skill published in the GitHub repository peturgeorgievv-factory/postfast-mcp (7 stars, last pushed 2d ago), licensed MIT. It adds 93 tokens to every session and 911 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-10-02.
