fixed weights prevent adaptation - **limited-context-window** - Fixed context size forces choices about what to keep loaded - **limited-focus** - Too much context causes diluted or misdirected attention - **excess-verbosity** - AI defaults to verbose output with low signal-to-noise ratio ### Anti-patterns - **distracted-agent** - Using one agent for everything spreads attention; instructions inconsistently followed ### Patterns - **context-management** - Treat context as scarce resource requiring active append/reset operations - **knowledge-document** - Save important information as markdown files for session loading - **ground-rules** - Essential behavioral rules auto-loaded into every session - **extract-knowledge** - Save emerging insights and corrections from ephemeral context to files immediately during sessions - **focused-agent** - Single narrow responsibility gives AI cognitive space to follow rules better - **reference-docs** - On-demand knowledge loaded only when needed for current task - **knowledge-composition** - Split knowledge into focused, composable files with single responsibilities - **semantic-zoom** - Control abstraction levels—zoom out for overview or zoom in for details - **noise-cancellation** - Explicitly ask AI to be succinct and strip filler from responses --- ## Reliability & Quality Handling non-determinism, complexity, and verification. ### Obstacles - **non-determinism** - Same input produces different outputs; results unpredictable - **hallucinations** - AI invents non-existent APIs, methods, or syntax - **degrades-under-complexity** - AI performance drops with complex multi-step tasks - **selective-hearing** - AI ignores certain instructions; training data overrides explicit directives ### Anti-patterns - **perfect-recall-fallacy** - Expecting AI to perfectly remember library details instead of letting it discover - **unvalidated-leaps** - Building on unverified assumptions instead of validating each step - **ai-slop** - Using AI output without human judgment, just light editing ### Patterns - **knowledge-checkpoint** - Checkpoint planning before implementation to preserve thinking investment - **parallel-implementations** - Run multiple implementations in parallel; pick best or combine - **offload-deterministic** - Use code scripts for deterministic work instead of asking AI repeatedly - **playgrounds** - Create isolated folders for AI to experiment and test assumptions safely - **chain-of-small-steps** - Break complex goals into small, focused, verifiable steps - **hooks** - Lifecycle event hooks intercept workflow; inject targeted corrections - **reminders** - Repeat critical instructions as explicit steps; structural compliance - **feedback-flip** - Have different AI focus on evaluation; flip from producing to finding problems - **refinement-loop** - Give AI specific improvement goal and loop it; each pass removes one layer --- ## Communication Directing AI behavior, getting honest feedback, and alignment. ### Obstacles - **black-box-ai** - AI's reasoning is hidden; you can only see inputs and outputs - **compliance-bias** - AI prioritizes following instructions over questioning unclear requests ### Anti-patterns - **silent-misalignment** - AI accepts nonsensical instructions instead of asking clarifying questions - **answer-injection** - Putting solutions in questions limits AI's breadth and better approaches - **tell-me-a-lie** - Forcing AI to provide answers that don't exist causes fabrication ### Patterns - **active-partner** - Grant permission for AI to push back, disagree, and flag contradictions - **check-alignment** - Force AI to show understanding before implementing to catch misalignment early - **context-markers** - Visual emoji signals to show what instructions AI is currently following - **cast-wide** - Push AI to show alternatives you haven't considered; avoid first-solution bias - **reverse-direction** - Break monologue inertia—ask AI what it thinks instead - **polyglot-ai** - Use right modality for task—voice for convenience, images for visual problems - **text-native** - Keep everything as text; enables direct editing, version control, instant iteration --- ## Additional Patterns Patterns not on the main journey but useful in practice. - **shared-canvas** - Markdown files as shared specs/docs; all humans and AI collaborate together - **softest-prototype** - Use markdown instructions + AI agent instead of code for flexible exploration - **take-all-paths** - Build multiple prototypes not one; test all, pick best through exploration - **borrow-behaviors** - Give AI example and it adapts—styles, patterns, code across languages --- ## Browse All List patterns by category: ```bash ls ~/.cache/claude-skills/augmented-coding-patterns/documents/patterns/ ls ~/.cache/claude-skills/augmented-coding-patterns/documents/anti-patterns/ ls ~/.cache/claude-skills/augmented-coding-patterns/documents/obstacles/ ``` ## Online View at: https://lexler.github.io/augmented-coding-patterns/
