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 C, and why

deepseek-worker scanned grade C 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 11d 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

DeepSeek Worker

Send a prompt to DeepSeek via browser and return the response.

Environment

  • URL: https://chat.deepseek.com
  • Browser: Chrome on localhost:9222 (managed by local-browser-tools)
  • Login: Required — session persisted in ~/.cache/browser-tools profile
  • Tools: browser-start.js, browser-nav.js, browser-eval.js, browser-screenshot.js

Input

prompt: string        # The text to send to DeepSeek
task_type: string     # qa | summary | translation | rewrite | extraction | comparison | brainstorming | analysis

Output

Always output this JSON block first:

{
  "site": "deepseek",
  "task_type": "<task_type>",
  "status": "success | partial | error",
  "answer": "<extracted response text>",
  "retry_count": 0,
  "elapsed_ms": 0,
  "error_reason": null
}

Then follow with a short human-readable summary (2–3 sentences max).


Workflow

Step 1 — Start browser

node ~/.pi/agent/skills/local-browser-tools/browser-start.js

Expected: ✓ Chrome already running on :9222 or ✓ Chrome started on :9222

If fails: return error status, stop.


Step 2 — Navigate to DeepSeek

node ~/.pi/agent/skills/local-browser-tools/browser-nav.js https://chat.deepseek.com

Take a screenshot and verify:

  • Textarea input box is visible with placeholder "Message DeepSeek"
  • Not showing a login form

If login page appears: return error_reason: "login_required", stop.


Step 3 — Locate input box

DeepSeek uses a <textarea> with placeholder="Message DeepSeek". Note: no aria-label.

Check:

!!document.querySelector('textarea[placeholder="Message DeepSeek"]')

Fallback selectors in order:

  1. textarea[placeholder="Message DeepSeek"]
  2. textarea

If no selector works after 3 attempts: trigger retry.


Step 4 — Insert prompt

DeepSeek uses React — setting textarea.value directly does NOT update React's internal state and will cause "Message is empty" on send. Must use nativeInputValueSetter:

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.
