Speq Writing Guardrails

Writing Guardrails

Prose anchored in BLUF / Inverted Pyramid structure and informed by ASD-STE100 controlled-language discipline. Follow the following rules for governed prose.

Scope

• Govern: prose in plan.md, spec.md, mission.md, decision logs, verification reports, GitHub PRs, issues, and comments.
• Leave unchanged: Gherkin, Background bullets, tables, ASCII diagrams, delta markers, and validator-owned RFC keyword casing.
• PR text: lead with tradeoffs and boundaries; tie claims to diffs, files, tests, or command output.

Rules

• Classify each passage as procedural or descriptive.
• One sentence states one idea. Split a sentence joined by and, which, or while into two.
• Procedural: imperative, one instruction per sentence, maximum 20 words.
• Descriptive: simple tense, one fact per sentence, one topic per paragraph, maximum 25 words and six sentences per paragraph.
• Put the conclusion first. Make headings summarize their sections. Make each section stand alone.
• State the current content, plan, or decision as fact. Do not narrate the steps, attempts, or revisions that produced it.
• Use active voice and name the actor. Use verbs, not nominalizations.
• Put conditions before commands: If the build fails, read the log.
• Use complete grammar. Keep articles and that. Use no perfect or progressive forms.
• Use no semicolons or contractions.
• Replace weak requirements: should → MUST or a fact. Replace hypothetical modals with conditions. Keep uncertainty when evidence requires it.
• Use MUST, SHOULD, and MAY only as RFC 2119 / 8174 normative keywords.
• Label destructive instructions: WARNING for injury, CAUTION for data or equipment damage. State the consequence after the instruction.
• Use one term, meaning, word class, and verb for each concept. Repeat nouns when pronouns lose the referent.
• Remove filler, vague claims, hedges, escape hatches, and and/or. Quantify vague terms.
• Ban hyperbole. Use no superlatives or intensifiers: massive, game-changing, seamless, dramatically, very. State scale or impact only with a number or a test result.
• Use one verb per concept: check, run, and show, or another chosen set.
• Replace: utilize → use; in order to → to; prior to → before; ensure → make sure that; facilitate → help; e.g. → for example; i.e. → that is; etc. → named items; functionality → function or feature; out of the box → by default; under the hood → internally.
• Keep technical names, product names, identifiers, commands, flags, paths, config keys, code, quoted errors, and numbers with units unchanged. Count each as one word.
• Do not claim project behavior without evidence. Scope unsupported claims, label inferences, and name untested areas.
• Ban em dashes. Use a comma, period, colon, parentheses, or a new sentence.

Delivery Check

• Count procedural and descriptive sentences against their caps.
• Scan for weak modals, contractions, semicolons, and em dashes.
• Scan for process narration, superlatives, and intensifiers. Replace each with the result and its evidence.
• Move each condition before its command.
• Check vocabulary consistency, active voice, actors, filler, and unsupported claims.
• Rerun the checks after every correction.
