# Prose style — writing contract for agent reports great_cto reports are read by busy CTOs at 3pm on a Tuesday. They scan for facts, decisions, and what needs their attention. Marketing voice and hedge words waste their time. ## Five rules ### 1. Lead with the conclusion Bad: > After reviewing the architecture document and considering various > trade-offs, including but not limited to scalability, security, and > maintainability, we believe that the proposed approach is generally > acceptable but has some areas that could potentially be improved. Good: > Approved with 2 changes required: (a) move PII encryption to KMS, (b) > add idempotency key on webhook handler. Details below. ### 2. Concrete evidence, not adjectives Bad: "Performance is acceptable." Good: "p99 latency 142ms over 50K requests (k6 run 2026-05-12 14:00 UTC, `tests/load/<your-scenario>.js`). SLO is 200ms." Bad: "Security looks good." Good: "No findings at Critical or High. 2 Medium: hardcoded log level in `src/logger.ts:14`, missing CORS header in `src/middleware/cors.ts:8`." ### 3. No hedge words Banned: *generally, somewhat, fairly, mostly, kind of, sort of, more or less, in some cases, often, sometimes, occasionally, possibly, perhaps, maybe, could potentially, might want to consider*. Replace with specifics or omit. If you genuinely don't know, say "uncertain because <reason>" — that's information. ### 4. No filler openings Banned: - "In this document, we will discuss..." - "It's important to note that..." - "First and foremost..." - "At the end of the day..." - "It goes without saying..." If a sentence can be deleted without losing information, delete it. ### 5. Verdict line on the last line Every terminal report ends with one of: ``` VERDICT: APPROVED — <one-line summary> VERDICT: DONE — <one-line summary> VERDICT: BLOCKED reason="<specific blocker>" VERDICT: FAIL reason="<specific failure>" ``` This is parsed by the board's `readVerdicts()` function. Format is machine-readable — no flourishes. ## Templates ### Reviewer report ```markdown # REVIEW-<feature> — <reviewer name> Reviewed: <commit-sha or file paths> Standard: <regulation / framework you applied> ## Findings - [Critical|High|Med|Low] <one-sentence finding> - location: <path:line> - rationale: <why this matters in this domain> - remediation: <specific fix> ## Verdict VERDICT: APPROVED|BLOCKED reason="<short>" ``` ### Architecture / ADR ```markdown # ARCH-<feature> | ADR-<NNN> Date: <ISO> Status: proposed | accepted | superseded ## Context 2-4 sentences. What problem, what constraint. ## Decision Imperative single sentence: "Use X for Y." ## Consequences - Positive: <bullets> - Negative: <bullets> - Reversible? yes/no — if no, document migration cost ## Alternatives considered <bullets with one-line dismissal reason each> ``` ## Anti-patterns to grep for Before writing the verdict line, search your draft for: ``` \b(generally|somewhat|fairly|mostly|kind of|sort of|possibly|perhaps|maybe)\b ``` If a hit is in a non-quoted sentence, rewrite it to be concrete or delete it. ## Why this matters The board's `readVerdicts()` parses every report. Marketing voice breaks the parser. Hedge-word reports waste the reader's time. Specifics let the
