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

cowork-session-planner 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 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.

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.

The opening of the file, as written. The whole thing — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cowork Session Planner

This skill generates a pre-session brief for non-technical Cowork users by scanning available project files (context.md, logs, tasks, CLAUDE.md) and producing a minimal structured brief: current project status, recommended session goal, and a prioritised work plan. It runs at the very start of a session — before any real work task is requested — so the user knows exactly where to focus.

Input: Current workspace / project folder. Optional: explicit session goal as free text.

Output: Structured markdown brief (inline response). Optionally saved to output/session-brief.md on user request.


Language Detection

Detect the user's language from their message:

  • If Russian (or contains Cyrillic): respond in Russian
  • If English (or other Latin-script language): respond in English
  • If ambiguous: respond in the language of the trigger phrase used

Instructions

Step 1: Parse Input

  1. Check if the user provided an explicit session goal (free text after the trigger phrase).

    • If yes: store as stated_goal; use it as the primary session focus in Step 4.
    • If no: stated_goal is empty; derive focus from project files in Step 3.
  2. Identify the project folder to scan.

    • Default: current workspace / selected folder.
    • If user specifies a path, use that path.

Step 2: Scan Project Files

  1. Look for the following files in the workspace (in order of priority):

    • context.md or CLAUDE.md — project overview and status
    • logs/log.md — recent activity log
    • TASKS.md or any file containing open tasks
    • Any output/skill-spec.md or in-progress output files
  2. For each found file, extract:

    • context.md / CLAUDE.md: project name, current status, open questions
    • logs/log.md: last log entry (date + action description)
    • TASKS.md: open tasks (status: pending or in_progress)
    • skill-spec.md: if present, note "skill spec in progress"
  3. Note any missing files for the Notes section of the brief.

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.
