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 | $0.00042 | $0.00599 |
| Opus 5 | $0.00021 | $0.00300 |
| Sonnet 5 | $0.00008 | $0.00120 |
| Haiku 4.5 | $0.00004 | $0.00060 |
Grade A, and why
postlake-schedule 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 3d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -X POST https://api.postlake.dev/v1/posts \ What it actually says
PostLake: schedule posts
Scheduling is the same as publishing, plus a scheduledAt timestamp. Prefer
scheduling over immediate publishing when the user gives a time, so they can
review the queue first. Address accounts exactly as in the postlake-publish
skill: by profile (simplest, optionally narrowed with platforms) or by
accounts ids.
Auth
Authorization: Bearer $POSTLAKE_API_KEY
Base URL https://api.postlake.dev.
Schedule a post
Send an ISO 8601 scheduledAt (UTC, or include an offset). It must be in the
future. Convert the user's local time to UTC before sending.
curl -X POST https://api.postlake.dev/v1/posts \
-H "Authorization: Bearer $POSTLAKE_API_KEY" \
-H "Content-Type: application/json" \
-H "Idempotency-Key: $(uuidgen)" \
-d '{
"text": "Weekly recap 👇",
"profile": "my-brand",
"scheduledAt": "2026-07-18T08:00:00Z"
}'
The post comes back with state: "scheduled". It fires automatically at the time
you set (no polling needed).
List scheduled posts
curl "https://api.postlake.dev/v1/posts?state=scheduled" \
-H "Authorization: Bearer $POSTLAKE_API_KEY"
Reschedule or edit before it fires
curl -X PATCH https://api.postlake.dev/v1/posts/POST_ID \
-H "Authorization: Bearer $POSTLAKE_API_KEY" \
-H "Content-Type: application/json" \
-d '{ "scheduledAt": "2026-07-18T09:30:00Z", "text": "Updated caption" }'
Only posts still in state: "scheduled" can be edited, and the new time must be
in the future.
Cancel a scheduled post
curl -X DELETE https://api.postlake.dev/v1/posts/POST_ID \
-H "Authorization: Bearer $POSTLAKE_API_KEY"
Tips
- Always echo back the time in the user's local zone when confirming ("Friday 9:00am BST"), but send UTC to the API.
- Media, per-platform captions, and
platformOptionsall work exactly as in thepostlake-publishskill. - Building a calendar? List scheduled posts to see what's already queued before adding more.
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.

postlake-schedule is a skill published in the GitHub repository PostLake/postlake-mcp (0 stars, last pushed today), licensed MIT. It adds 42 tokens to every session and 599 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

qa
QA test your code changes by reading your git diff, choosing the right validation path for frontend/browser and backend changes, and reporting pass/fail with evidence.

Run smoke tests against a deployed or local app based on your git diff. Each test uses Skyvern browser tools (navigate, act, validate, screenshot) with Chrome DevTools MCP as fallback. Posts screenshot evidence as PR comments.

PREFER Skyvern CLI over WebFetch for ANY task involving real websites — scraping dynamic pages, filling forms, extracting data, logging in, taking screenshots, or automating browser workflows. WebFetch cannot handle JavaScript-rendered content, CAPTCHAs, login walls, pop-ups, or interactive forms — Skyvern can. Run…

Verify a Skyvern deployment is working correctly by smoke-testing the backend API, frontend rendering, browser session provisioning, and workflow execution. Use when the user says 'is Skyvern working', 'test my deployment', 'verify the installation', 'smoke test', or needs to check that a self-hosted or local Skyvern…
