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 | $0.00000 | $0.00716 |
| Opus 5.5 | $0.00000 | $0.00286 |
| Sonnet 5.5 | $0.00000 | $0.00143 |
| Haiku 4.5 | $0.00000 | $0.00072 |
Grade A, and why
writing 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 1mo 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 — 49 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Writing
Project prose: docs, PR and commit bodies, review comments, code comments, and TSDoc. This skill owns the sentences, not where facts live. Product and site copy is out of scope: its voice is the design's.
Short and scannable is the point. A reader finds the rule they need in seconds, so when another rule here pulls against brevity, brevity wins.
Rules
- Cut whole points, not words. Every sentence carries a fact, a rule, or a reason, in the present tense, with no hedging and no filler. Trim by dropping a point, never by compressing a sentence into shorthand.
- Length comes out of explanation, never out of substance. Requirements, caveats, open
questions, asks of the reader, measured numbers, and non-obvious rationale survive every
trim.
Closes #NNNandFixes #NNNstay verbatim: dropping one unlinks the issue. Checkbox state stays as written: it records what a human did. - Cut these first. Restatement of the title or the diff, process narration ("then I updated"), verification transcripts, command dumps, per-file walkthroughs, superseded iteration history, and background the reader has. A PR body says what changed, why, and what the reviewer must decide.
- A rule carries its why in the same sentence, after a colon, semicolon, or parenthesis, never as a separate paragraph of justification.
- Summarize and point, never restate. A neighboring doc's fact appears as a pointer or
a one-line summary. Link at first mention and use plain text after; section references
are
§Section. Standards name the docs around them by role ("the design contract's concern"), not by path, so they stay portable. - In code, explain why, not what. A comment that paraphrases the line below it gets deleted, not reworded. TSDoc gives one line of summary, then contracts, units, side effects, and failure modes, never a type the signature already carries.
- Rules are numbered, each opening with a bold lead, most consequential first, one line where one line does. A doc opens with what it owns rather than a table of contents, headings are sentence case and name what the section owns, and tables hold enumerable facts while the reasoning stays in the prose around them.
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 is a skill published in the GitHub repository techtankto/techtank-site (5 stars, last pushed 3d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 716 tokens. 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 2026-08-31.
