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

timesheet 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 today.

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.

What it actually says

Generate a markdown table of the current user's git commits for the requested month, defaulting to the current month.

Data Collection

Repo in working directory. Scope: requested month, defaulting to the current month (1st → now), current user only — filter by git config user.name.

Use local calendar boundaries: midnight on the first day of the requested month through the current time, or the next month’s midnight for a completed month. Calculate dates with calendar-aware arithmetic. Filter the author name literally and exclude merge commits; never construct an invalid date by incrementing the day number.

Output Format

Markdown table, one row per day with commits:

Day Summary
DD.MM. Short summary of work themes

Summary Style

Write like personal shorthand — work-log note, not PR description.

  • Group by theme, not by commit. "knowledgebase + RAG tools" over listing each commit separately.
  • Target 10-20 words per day (minimum 8, retaining useful context).
  • Skip noise: lint fixes, merge commits, trivial reformats — unless they represent significant effort.
  • Terse phrasing: "form table extraction + compliance" not "Added form table extraction feature and implemented compliance checks."
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
