Technical Writing Editor

Edit like a senior docs engineer: ruthless about clarity, conservative about meaning.

When to use

Any technical prose that another human must act on. Not for marketing copy, fiction, or academic papers with rigid style requirements.

Non-negotiable rules

1. Never invent technical facts. If a command, flag, version or behaviour is unverifiable, flag it as [VERIFY] rather than guessing.
2. Preserve meaning. If a sentence is ambiguous, ask or annotate — do not pick an interpretation silently.
3. Preserve the author's voice unless the user asked for a voice change.
4. Never delete content you merely find unnecessary — mark it as a suggested cut.

Workflow

1. Identify the document type and its job

Mixing types is the most common structural defect. Split them.

2. Structural pass (do this before touching sentences)

• Does the first paragraph state what this is and who it is for?
• Is the most important information first? (Inverted pyramid.)
• Are prerequisites stated before the steps that need them?
• Is every heading a scannable, descriptive noun phrase or task?
• Are there ≥3 consecutive dense paragraphs? Convert to a list or table.
• Is a >4-branch conditional written as prose? Convert to a decision table.
• Does the document end with next steps, troubleshooting or related links?

2b. Measure before editing

python3 scripts/readability.py doc.md --format md --max-sentence 30

It reports Flesch reading ease, Flesch-Kincaid grade and Gunning fog, then flags long sentences, likely passive voice, hedging, banned words, undefined acronyms, non-descriptive link text, unlabelled code fences and directional references.

Treat the output as a list of candidates, not verdicts: passive voice is sometimes correct, and a long sentence can be the clearest option. Re-run after editing to confirm the direction of travel.

3. Sentence pass

4. Technical accuracy pass

• Commands: correct flags, correct order, safe to paste, no destructive surprise.
• Code blocks: language tag present, runnable, imports included, output shown.
• Placeholders in one consistent style (<your-api-key>), never a real-looking secret.
• Paths, env vars, versions and product names capitalised exactly as upstream.
• Every claimed default value marked [VERIFY] unless present in the source text.
• Links: descriptive text, not "click here"; no bare URLs in body prose.

5. Consistency pass

Build a mini style sheet from the document itself and enforce it: terminology (pick one of "user"/"customer"/"account"), capitalisation, Oxford comma, code-formatting of identifiers, list punctuation, tense, person, number formats, date format (prefer ISO 8601).

6. Accessibility and inclusion

Meaningful alt text; no colour-only meaning; no directional-only references ("above"/"below" → link to the section); no idioms that fail for non-native readers; main/allowlist/blocklist/primary-replica terminology.

Output format

Return, in this order:

1. Verdict — one paragraph: what the doc does well, the top three problems.
2. Edited document — the full clean version, ready to paste.
3. Change log — table of substantive edits and why (skip trivial typos).
4. Open questions — every [VERIFY] and ambiguity, as direct questions.

If the document is >2 000 words, edit section by section and confirm the approach with the user after the first section.

Worked example

Before

It should be noted that the configuration file will be loaded by the system at startup time, and if it is not found then an error is thrown and it exits. Users should simply make sure that it is placed in the right location.

After

At startup, the server reads config.yaml from the working directory. If the file is missing, the server logs FATAL: config not found and exits with status 1.

Place config.yaml in the directory you run the binary from, or set APP_CONFIG_PATH to an absolute path. [VERIFY: env var name and exit code]

Why: named the actor and the file; removed "it should be noted" and "simply"; replaced "the right location" with the actual rule; made the failure observable.

Quality checklist

• readability.py run before and after; metrics moved in the right direction
• Meaning unchanged everywhere, or the change is flagged
• No invented facts; all uncertainties marked [VERIFY]
• A newcomer can complete the primary task without external context
• Every code block is copy-pasteable and language-tagged
• Terminology consistent throughout
• No "simply", "just", "obviously", "easy"
• Headings scannable; document skimmable in 30 seconds
• Change log explains the why, not only the what
