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 | $0.00093 | $0.02212 |
| Opus 5 | $0.00046 | $0.01106 |
| Sonnet 5 | $0.00019 | $0.00442 |
| Haiku 4.5 | $0.00009 | $0.00221 |
Grade A, and why
technical-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 4d 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 — 129 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Technical writing
Overview
House style for technical documents, composed from conventions used across my repositories. The rules themselves are in English; documents keep their own language: a Dutch document is written and reviewed in Dutch. The structural and truth rules apply in any language; the vocabulary lists in references/style.md are English-specific and other languages carry their own. Core principle: a document states current, verified behavior, conclusion first, with every claim traceable to a source, and every fact living in exactly one place. A thin document beats an overstated one, because the author is the one saying it out loud.
These rules govern documents, not chat replies. Length and section rules apply to running prose, not to reference lists like this file.
When to invoke
Load this skill for any technical prose, then the matching document-type skill on top. These are routing hints; each skill's own body is the authority.
When a repository regularly produces documents, record the invocation in project memory: one line in its CLAUDE.md or the platform's equivalent, telling agents to load this skill for any technical prose there. A skill the project names loads every session; one left to recall loads only when someone thinks of it.
| The task is | Also load |
|---|---|
| A proposal, RFC, design doc, spec, or migration plan | writing-design-docs |
| Recording a decision, an ADR, a decision log entry | recording-decisions |
| A changelog entry, release notes, "what shipped" | writing-changelogs |
| A runbook, setup guide, procedure, troubleshooting entry | writing-runbooks |
| A tracker item: epic, story, task, bug report, spike, acceptance criteria | writing-issues |
| A migration or deprecation guide | writing-runbooks |
| A postmortem, incident report, root-cause analysis | writing-postmortems |
| Documenting an existing, under-documented system; regrounding stale docs against code | documenting-legacy-codebases |
| A process, lifecycle, or interaction diagram; drawing business logic | diagramming-processes |
| An API reference: endpoints, message payloads, DTOs, CLI commands, file formats, webhooks | documenting-contracts |
| Reviewing or rewriting someone else's text; the final pass before delivering any document | reviewing-technical-prose |
What ships with it
2 files 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.

technical-writing is a skill published in the GitHub repository riekelt/technical-writer (15 stars, last pushed 5d ago), licensed MIT. It adds 93 tokens to every session and 2,212 once invoked, about $0.0005 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.
