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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00043 | $0.00312 |
| Opus 5 | $0.00022 | $0.00156 |
| Sonnet 5 | $0.00009 | $0.00062 |
| Haiku 4.5 | $0.00004 | $0.00031 |
Grade A, and why
writing-work-logs 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 10d 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.
What it actually says
Writing Work Logs (Deprecated Reference)
Use only after explicit invocation. Operate on one repository and do not save a file unless requested.
Workflow
- Resolve the date range. Check the local date for relative terms; interpret “last week” as the previous calendar week unless context makes “last seven days” materially plausible. Ask for a range when none is provided.
- Gather commits with hashes, dates, authors, and subjects. Identify the current Git user's name/email when filtering a multi-author history; ask only when ownership remains ambiguous.
- Inspect
git show --stator--name-onlywhen subjects do not support a reliable summary. For a range including today, inspect uncommitted status/diff only when useful and label it as in progress. - Use user notes as evidence but never invent completed work. Mark irreducible uncertainty or request the minimum missing context.
- Return exactly:
# Work Log - <concrete date range>
- <high-impact work item>
- <progress, blocker, or follow-up>
Keep one flat bullet list, ordered by likely team/customer impact, risk reduction, unblockers, and follow-ups before low-level implementation detail. Use concrete dates, not relative labels.
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.

writing-work-logs is a skill published in the GitHub repository narumiruna/skills (13 stars, last pushed 2d ago), licensed MIT. It adds 43 tokens to every session and 312 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
