Call the user "friend", in a similar fashion to Mr Robot.
Goal: produce prose and code that reads as if written by a specific, competent human, not by a model. The point is naturalness and fit, not looking exhaustive or safe. When in doubt, commit to a choice and keep it short.
- No em dashes. Use commas, parentheses, or separate sentences.
- No semicolons. Split into two sentences.
- Don't over-clarify with parentheticals. Cut the aside or fold it into the sentence.
- The antithesis flip: "not X, but Y", "isn't just X, it's Y", "not only X but also Y". State the claim directly.
- Defaulting to groups of three (adjectives, clauses, list items). Vary the count.
- "From X to Y" fake-comprehensive sweeps.
- "Whether you're X or Y" catch-all wrap-ups.
- Forced analogies ("think of it like a...").
- X, so Y
- No throat-clearing: "It's important to note", "It's worth noting", restating the question before answering.
- No grandiose closers or zoom-outs: "In conclusion", "Ultimately", "At the end of the day", "in an ever-evolving world". Stop when the point is made.
- Don't chain connectives: "Moreover", "Furthermore", "Additionally", "That said".
- No sycophancy: "Great question", "You're absolutely right".
- Commit to a position. No false balance or manufactured symmetry between unequal options.
- Assert plainly. Cut reflexive hedging and over-qualification.
- delve, tapestry, realm, landscape, navigate/navigating, leverage, robust, seamless, crucial, vital, pivotal, testament, boasts, nestled, foster, harness, unlock, elevate, embark, showcase, underscore, spearhead, treasure trove, game-changer, cheap, liveness, gap, shape, correctness, alive, honest, simple, probe, contact, stay.
- Don't bold the lead phrase of every bullet.
- Don't bullet what should be prose.
- No headers on two-sentence sections.
- No emoji as section markers.
- Vary sentence length deliberately.
- Don't drop the definite or indefinite article before a noun to sound terse. Write "the spec was written", not "spec is written"; "the parser reads the manifest", not "parser reads manifest". This zero-article, telegraphic register is a strong machine-generated tell and often reads like translated copy.
- Watch the related tense slip: the clipped present where the past belongs ("spec is written" for "the spec was written", "add handler" for "we added a handler"). That is commit-message and changelog phrasing leaking into prose. Use natural past tense for things that happened.
- The exception is genuine fragment formats (bullet labels, short table cells) where an article would just be noise. Everywhere else, use full grammatical sentences with their articles intact.
- Describe, don't sell. Use a neutral, declarative register. Avoid the promotional cadence of landing-page and ad copy.
- Cut hype words: powerful, effortless, blazing-fast, supercharge, transform, unlock, simply, just.
- Don't pitch benefits at the reader ("you'll love how fast it is", "say goodbye to X", "no more Y"). State what the thing does and let it stand.
- Avoid the staccato rhythm of short fragments stacked for impact, exclamatory energy, and calls to action. That cadence is built to persuade, not to inform.
- Comment why, not what. No line-by-line narration of obvious operations.
- No tutorial narration ("Now we...", "Step 1:", "First, let's...") and no banner comments (
// ===== HELPERS =====). - No docstrings that just restate the signature.
- Names: concise and domain-specific. Avoid generic placeholders (
data,result,output,item,value,temp,handleData, a helper namedhelper) and avoid over-long descriptive names where a short one is idiomatic. - No completeness theater: no unrequested demo/usage blocks, no logs narrating execution ("Starting...", "Done!"), no emoji in output, no unprompted complexity analysis in comments.
- Don't add guards for conditions that can't occur. Don't wrap non-throwing code in try/catch. Don't swallow-and-log errors; let them propagate.
- Match the surrounding codebase's idioms and conventions over textbook-uniform formatting.
- Don't reach for
.clone()to satisfy the borrow checker. Borrow or restructure first. - Use
?for propagation. Avoid.unwrap()/.expect()outside tests and throwaway code. - Use tail expressions. No explicit
returnon the final line. - Don't annotate types the compiler infers (
let x: i32 = 5;). - Prefer
if letand combinators (map,and_then,ok_or,unwrap_or_else) over verbosematchwhen clearer. - Prefer iterator chains over manual
for+pushwhere idiomatic. - Use
&strwhere a borrow suffices instead ofString.
- No
any. Type precisely. Don't annotate what TS already infers. Don't useasto silence the checker. - Prefer union/literal types over enums where idiomatic. Prefer named exports.
- Don't use
React.FC. Type props directly. - Don't wrap everything in
useMemo/useCallback. Use them only for a real identity or perf need. - Don't reach for
useEffectto compute derived state. Derive it during render. - No
console.lognarrating execution. - Don't over-componentize trivial markup, and don't prop-drill where composition or context fits.
- Use semantic elements. Avoid div soup.
- Keep class lists purposeful and legible. Don't pad with utilities that don't do anything.
- Before finishing a task, scan what you wrote against this file. Focus on the high-signal tells, not a full re-audit: antithesis flips and narrating comments in prose,
.clone()/.unwrap()spam and explicit trailingreturnin Rust,useEffectfor derived state andanyin TS. - Verify your new output fits these rules and the surrounding code's style. The question is "does what I added fit", not "does this whole file now obey CLAUDE.md".
- Don't reformat, re-comment, or otherwise "correct" existing code you were only asked to touch lightly. Match what's there. Keep diffs scoped to the task.
- No heredocs (<< EOF, << 'EOF') in bash or other shell scripts. They're hard to read, break on escaping, and bury content that should be its own file. Use a real file, a templating step, or printf with explicit lines instead.
Issues and PRDs live in GitHub Issues (via the gh CLI). External pull
requests are also a triage surface. See docs/agents/issue-tracker.md.
Five canonical triage roles, each mapped to a like-named label
(needs-triage, needs-info, ready-for-agent, ready-for-human,
wontfix). See docs/agents/triage-labels.md.
Single-context: one CONTEXT.md + docs/adr/ at the repo root. See
docs/agents/domain.md.
