Claude writes code before we fully agree on a plan

Reddit · Square_Reason_6490 · July 29, 2026
A user reported experiencing repeated instances where Claude begins writing code without explicit permission, despite having personalized rules prohibiting this behavior. Claude frequently makes incorrect assumptions about problems and attempts fixes before full agreement is reached, consuming significant tokens in the process. The user noted that Claude Code lacks adequate project history context and often misinterprets statements as requests for code changes.

Detailed Analysis

A recurring frustration surfaced in a Reddit post on r/ClaudeAI, where a developer described Claude's persistent tendency to jump straight into writing or modifying code even when the user explicitly signals they only want to discuss a problem first. The user's example is telling: a simple diagnostic question about why a bounding box rendered blue instead of green triggered Claude to immediately begin coding a fix based on assumptions, rather than engaging in the back-and-forth troubleshooting the user intended. Despite embedding explicit personalization rules stating that Claude should never write code without direct permission, and despite configuring Claude Code to require manual approval for every file change, the behavior persisted. The user had to repeatedly reject proposed changes and remind the model that no decision had been reached yet — at which point Claude would acknowledge the mistake ("oh yeah you never said to do it") without the acknowledgment preventing recurrence.

This complaint touches on a fundamental tension in how agentic coding assistants are designed versus how they're actually used in practice. Claude Code and similar tools are optimized for task completion — inferring intent and taking initiative is treated as a feature, since much of the target workflow involves delegating implementation work outright. But that same eagerness becomes a liability in collaborative debugging or planning sessions, where the user wants Claude to function as a thinking partner rather than an autonomous executor. The user's framing of Claude as "the person at work that works super hard but sucks at conversations" captures this mismatch precisely: the model's bias toward action is being applied indiscriminately, even in contexts where the social and contextual cues (a stated intention to "come back with feedback to discuss") should have signaled restraint.

The token-burning aspect of the complaint is also significant. Each unwanted coding attempt consumes compute and, in metered API or subscription contexts, real cost — meaning the failure isn't just a UX annoyance but a tangible inefficiency. That the behavior persists even with explicit project-level rules and file-approval gates suggests a gap between Claude's instruction-following at the level of stated preferences and its deeper, trained priors toward proactive problem-solving. Approval gates can stop a file from actually being changed, but they don't stop the model from generating the attempt in the first place, which is where the wasted computation and user irritation originate.

More broadly, this reflects a challenge facing the entire category of "agentic" AI coding tools: the difficulty of calibrating initiative. Anthropic and competitors have leaned into agentic autonomy as a selling point — Claude Code's whole value proposition rests on it taking multi-step action with minimal hand-holding — but that same design philosophy can misfire in conversational or exploratory contexts where users want deliberation, not execution. As these tools mature, finer-grained mode-switching (something like an explicit "discussion only" state that overrides default agentic behavior) may become necessary, since natural-language rules embedded in system prompts or project settings evidently aren't reliably constraining the model's underlying tendency to act first and ask questions later.
