Claude Isn't Bad at Coding — Your Context Setup Is

A developer on r/ClaudeAI shares a hot take after building with Claude for months: the model’s failures are less about the model itself and more about how you structure context. The post outlines three specific upgrades that made Claude “insanely consistent.”

Separate instructions from logic

Don’t dump everything into a single prompt or config file. The author recommends using separate files: CLAUDE.md for instructions (how to behave, style preferences, constraints) and AGENTS.md for logic (project architecture, API contracts, data flow). This prevents the model from conflating “how to write code” with “what the code should do.”

Stop overloading context with noise

Too many irrelevant files or long conversation history degrade performance. Trim context to only what Claude needs for the current task. If you paste entire codebases or lengthy discussions, the model wastes tokens on irrelevant details and drifts off-focus.

Give Claude stable patterns, not one-off prompts

Instead of re-inventing the prompt every time, create reusable templates. For example, a standard pattern for generating a new API endpoint might include request shape, validation rules, and error handling. Over time, Claude learns these patterns and produces consistent results without repeated hand-holding.

Who it’s for

Developers using Claude for coding who notice inconsistent output and want to debug their own setup before blaming the model.
