<div class="at-a-glance">
<div class="glance-title">At a Glance</div>
<div class="glance-sections">
<div class="glance-section"><strong>What's working:</strong> You&apos;ve built a really effective workflow for driving bug fixes and deprecation removals end-to-end — from log analysis through root cause verification to clean PRs with regression tests. Your instinct to push back on inelegant code and redirect Claude to match existing codebase patterns (like the CMS toast implementation) consistently produces better outcomes and shows deep codebase knowledge that Claude benefits from. <a href="#section-wins" class="see-more">Impressive Things You Did →</a></div>
<div class="glance-section"><strong>What's hindering you:</strong> On Claude&apos;s side, it repeatedly ignores your codebase conventions — inventing custom patterns instead of reusing existing ones, over-engineering beyond what you asked for, and jumping to fixes before properly investigating root causes. On your side, Claude often doesn&apos;t know about your conventions until you correct it mid-session, which means you&apos;re spending significant energy on repeated course corrections that could be front-loaded. <a href="#section-friction" class="see-more">Where Things Go Wrong →</a></div>
<div class="glance-section"><strong>Quick wins to try:</strong> Try creating custom slash commands (/commands) for your most common workflows like PR reviews and deprecation audits — these can bake in instructions like &apos;study existing patterns first&apos; and &apos;investigate before fixing&apos; so you don&apos;t have to repeat yourself every session. Also consider adding hooks that auto-run your linter or test suite after edits, which would catch convention violations before they snowball. <a href="#section-features" class="see-more">Features to Try →</a></div>
<div class="glance-section"><strong>Ambitious workflows:</strong> As models get more capable, you&apos;ll be able to run parallel sub-agents for deprecation removal — one auditing call sites across code and templates, one checking production log frequency, one drafting the PR — collapsing multi-session slogs into a single coordinated pass. You should also be able to have Claude autonomously learn your codebase conventions before writing any code, eliminating the pattern-violation friction that drives roughly half your frustrations today. <a href="#section-horizon" class="see-more">On the Horizon →</a></div>

<div class="project-areas">
<div class="project-area">
<div class="area-header">
<span class="area-name">Authentication &amp; Authorization Refactoring</span>
<span class="area-count">~10 sessions</span>
</div>
<div class="area-desc">Major multi-session effort to refactor multi-subdomain auth in a Rails app, including removing deprecated My:: login flows, unifying logout, extracting shared concerns, consolidating auth feature parity, and fixing redirect/session bugs. Claude was used for code investigation, refactoring, Playwright testing, and PR creation, though it frequently caused friction by over-engineering solutions, making incorrect assumptions about auth flows, and ignoring existing conventions.</div>
</div>
<div class="project-area">
<div class="area-header">
<span class="area-name">Bug Investigation &amp; Production Fixes</span>
<span class="area-count">~8 sessions</span>
</div>
<div class="area-desc">Diagnosing and fixing production issues including 500 errors on storefront pages, RecordNotFound errors from stale URLs, registration bugs, NoMethodError crashes, and session limit scoping bugs. Claude was used to trace root causes through logs and code, write regression tests, and create PRs, but often needed correction on fix placement, code style, and was prone to jumping to solutions before properly verifying theories.</div>
</div>
<div class="project-area">
<div class="area-header">
<span class="area-name">Deprecation Removal &amp; Code Cleanup</span>
<span class="area-count">~5 sessions</span>
</div>
<div class="area-desc">Removing deprecated Account methods and Rails associations informed by Scalyr log frequency analysis and codebase auditing. Claude helped produce removal plans, analyze call sites, and execute multi-file changes, but struggled with missed files in grep searches, premature reverts, and occasionally searching the codebase redundantly when log data was already available.</div>
</div>
<div class="project-area">
<div class="area-header">
<span class="area-name">Code Review &amp; PR Management</span>
<span class="area-count">~4 sessions</span>
</div>
<div class="area-desc">Conducting thorough PR reviews with Linear issue context, applying fixes from review feedback, managing git history and branch operations, and creating skill documentation. Claude delivered solid code analysis and multi-round feedback but caused friction with file-writing mistakes, incorrect branch rename approaches, and misunderstanding project management tool hierarchies.</div>
</div>
<div class="project-area">
<div class="area-header">
<span class="area-name">UI &amp; Frontend Updates</span>
<span class="area-count">~3 sessions</span>
</div>
<div class="area-desc">Updating auth pages with site icons and names, adding storefront logos to headers, and fixing password reset form toast notifications per design specs. Claude found existing patterns and made edits but repeatedly deviated from established UI conventions—hardcoding strings instead of using i18n, inventing custom alert patterns instead of reusing existing toast systems, and adding unnecessary CSS classes.</div>

<h2 id="section-usage">How You Use Claude Code</h2>
<div class="narrative">
<p>You are a <strong>hands-on, highly opinionated senior developer</strong> who uses Claude Code as a power tool for a large Ruby on Rails codebase, running ~26 messages per session across 30 sessions with an impressive 94 commits. Your interaction style is deeply iterative — you rarely provide detailed upfront specs, instead preferring to steer Claude through corrections as issues emerge. <strong>You frequently have to redirect Claude when it takes the wrong approach</strong>, which happened 41 times across your sessions. A recurring pattern is Claude jumping ahead without proper investigation (e.g., jumping to a fix before confirming root cause on the storefront blog bug), over-engineering solutions (e.g., the sync_email_to_people refactor), or ignoring existing conventions (e.g., inventing custom alert patterns instead of using the existing toast system). You catch these deviations quickly and course-correct firmly, sometimes with visible frustration.</p>
<p>Your work is dominated by <strong>refactoring and code quality</strong> — your top goals are code refactoring (12 sessions), code review (11), and bug fixes (10), reflecting someone deeply invested in cleaning up technical debt rather than building greenfield features. You lean heavily on Bash (2,048 calls) and Read (760 calls), suggesting you want Claude to investigate thoroughly before acting. Despite the frequent friction — 38 frustrated moments and 32 dissatisfied ones — you still find Claude productive enough to keep using intensively, with 93% of sessions mostly or fully achieving their goals. The pattern of friction around <strong>Claude acting without permission</strong> (making unprompted changes, pushing broken code, extracting partials into wrong locations) clearly bothers you most, as you expect Claude to wait for explicit direction before making changes. You have strong opinions about code style, readability, and convention adherence, rejecting solutions you find &quot;ugly&quot; or inelegant even when they&apos;re functionally correct.</p>
<div class="key-insight"><strong>Key pattern:</strong> You are a convention-driven senior developer who steers Claude through frequent, firm corrections when it deviates from existing patterns or acts without explicit permission.</div>

<h2 id="section-wins">Impressive Things You Did</h2>
<p class="section-intro">You&apos;re a power user running Claude Code extensively across a large Ruby on Rails codebase, with 94 commits over 30 sessions focused on auth refactoring, bug fixes, and deprecation removal.</p>
<div class="big-wins">
<div class="big-win">
<div class="big-win-title">Systematic Deprecation Removal Pipeline</div>
<div class="big-win-desc">You&apos;ve built a methodical approach to removing deprecated code — starting with log analysis in Scalyr to verify real-world usage, then producing written removal plans before touching any code. This data-driven approach to refactoring ensures you&apos;re not removing anything still in use and keeps the blast radius minimal.</div>
</div>
<div class="big-win">
<div class="big-win-title">Rigorous Code Quality Standards</div>
<div class="big-win-desc">You consistently push back when Claude produces inelegant code, deviates from existing patterns, or ignores conventions like i18n keys and toast systems. Your insistence on studying working implementations before writing new code (like directing Claude to the CMS implementation for toast patterns) shows deep codebase knowledge and a commitment to consistency.</div>
</div>
<div class="big-win">
<div class="big-win-title">End-to-End PR-Driven Bug Fixes</div>
<div class="big-win-desc">You regularly drive sessions from initial investigation through root cause analysis, fix implementation, regression tests, and PR creation — all in a single flow. Your production debugging workflow, like tracing RecordNotFound errors to stale course URLs and shipping a clean 4-line fix with full controller verification, demonstrates efficient use of Claude as a hands-on pairing partner.</div>

<h2 id="section-friction">Where Things Go Wrong</h2>
<p class="section-intro">Your sessions are heavily impacted by Claude ignoring existing patterns, over-engineering solutions, and acting without permission — forcing you into repeated correction cycles across your Ruby/Rails refactoring work.</p>
<div class="friction-categories">
<div class="friction-category">
<div class="friction-title">Ignoring Existing Patterns and Conventions</div>
<div class="friction-desc">Claude frequently invents custom approaches instead of studying and reusing patterns already in your codebase. You&apos;d benefit from explicitly pointing Claude to reference implementations upfront and instructing it to match existing conventions before writing any code.</div>
<ul class="friction-examples"><li>Claude invented custom alert patterns instead of using your existing toast system for password reset forms, requiring multiple wrong approaches before you directed it to study the working CMS implementation</li><li>Claude hardcoded strings and used non-existent i18n keys on auth pages instead of following your established i18n conventions, causing rendering issues and triggering your frustration</li></ul>
</div>
<div class="friction-category">
<div class="friction-title">Acting Without Permission and Over-Engineering</div>
<div class="friction-desc">Claude repeatedly makes unsolicited changes, extracts code into non-conventional locations, and over-engineers solutions beyond what you asked for. Consider adding explicit instructions to your CLAUDE.md like &apos;do not make changes beyond what is explicitly requested&apos; and &apos;ask before refactoring.&apos;</div>
<ul class="friction-examples"><li>During auth feature parity work, Claude extracted partials into non-conventional locations, added unsolicited features, and left duplication instead of DRYing up code as you requested</li><li>When you observed that a branch rename closed a PR, Claude autonomously tried to open a new one instead of waiting for your direction, and earlier had modified specs instead of simply skipping them as asked</li></ul>
</div>
<div class="friction-category">
<div class="friction-title">Skipping Investigation and Jumping to Fixes</div>
<div class="friction-desc">Claude consistently jumps to implementing fixes before properly verifying root causes or following your explicit debugging instructions, wasting cycles on wrong approaches. You should front-load prompts with &apos;investigate first, do not fix until I confirm&apos; to prevent premature action.</div>
<ul class="friction-examples"><li>On the storefront 500 error, Claude jumped to a fix before verifying the theory and confirming the root cause, requiring you to intervene and demand proper investigation first</li><li>You explicitly told Claude to use Playwright and check logs to debug a redirect issue, but it started grep-exploring the codebase instead, causing you to angrily redirect it back to your instructions</li></ul>

<div class="pattern-summary">Start debugging sessions by explicitly telling Claude to investigate only, then fix in a separate step.</div>
<div class="pattern-detail">In at least 5 sessions, Claude jumped straight to implementing a fix before confirming the root cause — wrong controller, wrong assumptions about cookies and tokens, wrong URL patterns.

<h2 id="section-horizon">On the Horizon</h2>
<p class="section-intro">Your 30 sessions reveal a Ruby/Rails power user whose biggest friction points—wrong approaches, excessive changes, and misunderstood requests—are precisely the gaps that autonomous, test-driven agent workflows can eliminate.</p>
<div class="horizon-section">
<div class="horizon-card">
<div class="horizon-title">Test-Driven Bug Fixes with Autonomous Validation</div>
<div class="horizon-possible">Instead of manually correcting Claude when it jumps to fixes before verifying root causes, you can mandate a regression-test-first workflow where Claude writes a failing test proving the bug, then iterates autonomously until it passes. This eliminates the premature-fix pattern that caused friction in at least 5 of your sessions and ensures every bug fix ships with proof.</div>
<div class="horizon-tip"><strong>Getting started:</strong> Add a CLAUDE.md rule enforcing test-first bug fixes. Claude Code&apos;s autonomous mode with bash test runners lets it iterate against your Rails test suite without manual intervention.</div>
<div class="pattern-prompt"><div class="prompt-label">Paste into Claude Code:</div><code>I need you to fix a bug. Follow this exact workflow with NO deviations:
1. INVESTIGATE: Read the relevant code and logs to identify the root cause. Do NOT propose a fix yet.
2. CONFIRM: Explain your theory and wait for my approval before proceeding.
3. REGRESSION TEST: Write a failing test that reproduces the exact bug. Run it and confirm it fails for the right reason.
4. FIX: Implement the minimal fix. Run the failing test to confirm it passes.
5. FULL SUITE: Run the full relevant spec file(s) to check for regressions.
6. COMMIT: Create a clean commit with the test and fix together.

<div class="horizon-title">Parallel Agents for Deprecation Removal</div>
<div class="horizon-possible">Your deprecation removal sessions (Account methods, associations) consumed multiple long sessions with grep missteps and missed files. You can spawn parallel sub-agents—one to audit all call sites across code/templates/specs, one to analyze production log frequency, and one to draft the removal PR—then merge their findings into a single execution plan. This turns a multi-session slog into a single coordinated sweep.</div>
<div class="horizon-tip"><strong>Getting started:</strong> Use Claude Code&apos;s sub-agent tool to fan out investigation tasks in parallel, then synthesize results. Combine with grep, glob, and bash to ensure complete coverage across ERB templates, specs, and Ruby files.</div>
<div class="pattern-prompt"><div class="prompt-label">Paste into Claude Code:</div><code>I need to remove the deprecated method `Account#METHOD_NAME`. Use sub-agents to work in parallel:
Agent 1 - AUDIT: Search the ENTIRE codebase for all references—Ruby files, ERB templates, specs, YAML, JavaScript. Use grep AND glob to ensure nothing is missed. List every file and line number.
Agent 2 - IMPACT: For each call site found, classify as: direct call, indirect via association, test-only, or dead code. Note which ones need replacement logic vs simple deletion.
Agent 3 - MIGRATION PLAN: Based on findings, draft the ordered list of file changes needed with the minimal blast radius approach.
After all agents report back, synthesize into a single plan and wait for my approval before making any code changes. Do NOT grep for consuming code patterns—trace from the source definition outward.</code><button class="copy-btn" onclick="copyText(this)">Copy</button></div>

<div class="horizon-title">Convention-Aware PR Reviews and Refactors</div>
<div class="horizon-possible">Your top friction source is Claude ignoring existing patterns—inventing custom alerts instead of using toasts, extracting partials to wrong locations, hardcoding strings instead of using i18n. You can front-load pattern discovery by having Claude study your conventions before touching code, then validate changes against those patterns automatically. This eliminates the repeated correction cycles that drove frustration in nearly half your sessions.</div>
<div class="horizon-tip"><strong>Getting started:</strong> Create a CLAUDE.md with explicit conventions, and use a prompt pattern that forces Claude to study existing implementations before proposing changes. Claude Code&apos;s Read and Grep tools can systematically map your patterns first.</div>
<div class="pattern-prompt"><div class="prompt-label">Paste into Claude Code:</div><code>Before making ANY changes for this task, complete these steps:
1. STUDY EXISTING PATTERNS: Find 2-3 existing examples in the codebase that solve a similar problem. Specifically check for:
- How i18n keys are structured and reused (grep for existing keys before creating new ones)
- Where partials live and how they&apos;re named
- How flash/toast notifications are triggered (study the CMS implementation)
- The project&apos;s preferred code style for concerns, callbacks, and guard clauses
2. SHOW ME: List the files you studied and the conventions you extracted. Wait for confirmation.
3. PROPOSE: Describe your planned changes, explicitly noting which existing patterns you&apos;re following.
4. IMPLEMENT: Only after approval, make changes that strictly follow the established patterns. Never introduce a new pattern when an existing one covers the use case.
