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.

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 | $0.00095 | $0.01155 |
| Opus 5.5 | $0.00038 | $0.00462 |
| Sonnet 5.5 | $0.00019 | $0.00231 |
| Haiku 4.5 | $0.00010 | $0.00115 |
Grade A, and why
writing:no-diary 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.
How it starts
The opening of the file, as written. The whole thing — 87 lines — stays where its author put it; the contents beside it link to each section on GitHub.
No Diary
Arguments
$ARGUMENTS is freeform. Resolve it to concrete text:
- A path, optionally with a line range, reads that file.
- A PR or MR number or URL reads the body with the commands in
references/surfaces.md. - A section name or heading locates it in the artifact under discussion.
- A description with no target names the problem in the deliverable in play.
- A fraction or a keep-list (
50%,keep: the warning and the upstream link) sets the target length. Cut to it, taking theRemovalsin order, and say what went beyond the diary.
With no arguments, resolve the target in this order: text the user pasted this turn, the file this session last wrote or edited, then the PR for the current branch. Ask only when two candidates are equally live.
Output
- A file. Edit it in place.
- A PR or MR body. Write the new body under
tmp/, then apply it with the command inreferences/surfaces.md. Confirm first when the user did not name the PR. - Pasted text. Return the rewrite in your reply and leave the disk untouched.
Then report what you cut, grouped by the Removals headings, in a few lines.
The Test
Every sentence changes what the reader does. A sentence explaining why a decision was right, what it replaced, or where it came from fails.
Delete whole sentences. Cut within a sentence only for the cases in Gotchas.
Judge the text as a reader who was not in the session. For a whole artifact rather than a passage, dispatch a general-purpose agent that loads writing:no-diary and writing:writing and works from the artifact alone, plus its diff where one exists, with no session transcript.
The rewrite is done when every sentence passes the test and every fact a reader needs from the original survives.
Removals
- Change evolution. The shapes the work passed through. Any sentence needing an earlier draft to parse, and sequencing words such as "originally", "initially", "then", "turned out", "along the way", "ended up".
- Session leakage. The conversation inside the artifact: feedback echoed as commentary, a reviewer's question answered in a code comment, the user's own phrasing quoted back.
- Past states. What the code or doc used to be, and how bad it was. Remove the thing rather than commenting on its removal.
- Provenance and deliberation. Where an idea came from, what it beat, why a rule is correct. Alternatives belong in the commit or the PR body, so when the artifact is a PR body, keep a decision's reason in one clause.
- Restatement. Prose that re-describes the diff: file inventories, structural tours, a paragraph per function. Name the function instead.
- Self-reference. The artifact describing itself, its own sections, or harness behavior the harness already provides.
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.
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:no-diary is a skill published in the GitHub repository bendrucker/claude (18 stars, last pushed today), licensed MIT. It adds 95 tokens to every session and 1,155 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-09-03.
