update-log

update-log is a skill for Claude Code from benthamite/dotfiles. It costs 57 tokens per session (3,190 once invoked), scanned A, original, no licence file.

An end-of-session bookkeeping task for updating a project's session log. It is meant to be run only when the user explicitly requests a log update.

In plain words
What is it for?
Use it with `/update-log` or an explicit request to update the log, including when the request comes from the session's end-of-work process.
Why use it?
Session records can become inconsistent if they are edited manually or updated at the wrong time. This provides the designated way to handle that bookkeeping.

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

update-log 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 6d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/test_write_receipt.py, scripts/write_receipt.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 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.
