You've explained your architecture, fixed bugs together, made important decisions. Then suddenly... Claude has no idea what you're talking about.</p> <p><strong>It's not just new sessions.</strong> Claude loses context in multiple ways:</p> <ul> <li> <strong>New sessions</strong> — Start fresh, explain everything again</li> <li> <strong>Context compaction</strong> — Long conversations get summarized, details lost</li> <li> <strong>Token limits</strong> — Big codebases push out earlier context</li> <li> <strong>Weeks of work</strong> — That bug fix from 3 weeks ago? Gone</li> </ul> <p>Every time this happens, you're re-explaining the same architecture, the same decisions, the same gotchas. Over and over.</p> <h2> The Solution: External Memory </h2> <p>I built <a href="https://ctx-vault.com" rel="noopener noreferrer">ContextVault</a> — an external context management system for Claude Code. Instead of relying on Claude's internal context (which gets lost), your knowledge lives in <strong>markdown files that Claude reads automatically</strong>.</p> <h3> How It Works </h3> <ol> <li> <strong>You work with Claude</strong> — fixing bugs, making decisions, building features</li> <li> <strong>ContextVault captures knowledge</strong> — using 25 slash commands like <code>/ctx-error</code>, <code>/ctx-decision</code>, <code>/ctx-doc</code> </li> <li> <strong>Knowledge persists externally</strong> — in <code>.claude/vault/</code> as markdown files</li> <li> <strong>Every session, Claude reads your vault</strong> — full context, instantly </li> </ol> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code><span class="c"># Install in 30 seconds</span> curl <span class="nt">-sL</span> https://ctx-vault.com/install | bash </code></pre> </div> <h2> Why External Memory Beats Internal Context </h2> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Problem</th> <th>Internal Context</th> <th>ContextVault</th> </tr> </thead> <tbody> <tr> <td>New session</td> <td>❌ Lost</td> <td>✅ Preserved</td> </tr> <tr> <td>Context compaction</td> <td>❌ Summarized away</td> <td>✅ Preserved</td> </tr> <tr> <td>Token limits</td> <td>❌ Pushed out</td> <td>✅ Preserved</td> </tr> <tr> <td>Weeks later</td> <td>❌ Forgotten</td> <td>✅ Preserved</td> </tr> <tr> <td>Team sharing</td> <td>❌ Impossible</td> <td>✅ Commit to git</td> </tr> </tbody> </table></div> <h2> Key Features </h2> <h3> Two-Tier Vault System </h3> <ul> <li> <strong>Global vault</strong> (<code>~/.claude/vault/</code>) — Cross-project knowledge, patterns, best practices</li> <li> <strong>Project vault</strong> (<code>./.claude/vault/</code>) — Project-specific architecture, decisions, configs</li> </ul> <h3> 25 Slash Commands </h3> <div class="table-wrapper-paragraph"><table> <thead> <tr> <th>Command</th> <th>Use When</th> </tr> </thead> <tbody> <tr> <td><code>/ctx-error</code></td> <td>Fixed a bug</td> </tr> <tr> <td><code>/ctx-decision</code></td> <td>Made an architecture choice</td> </tr> <tr> <td><code>/ctx-doc</code></td> <td>Learned something useful</td> </tr> <tr> <td><code>/ctx-plan</code></td> <td>Working on multi-step task</td> </tr> <tr> <td><code>/ctx-handoff</code></td> <td>Ending your session</td> </tr> <tr> <td><code>/ctx-bootstrap</code></td> <td>New project — auto-document codebase</td> </tr> </tbody> </table></div> <h3> Smart Hooks </h3> <p>ContextVault reminds you to document at meaningful milestones — after completing tasks, fixing bugs, or ending sessions. Configurable enforcement levels: light, balanced, or strict.</p> <h2> Real Example </h2> <p><strong>Before ContextVault</strong> (week 3 of a project):<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>You: "Fix the auth bug" Claude: "What auth system are you using? Can you explain the architecture?" You: *sighs, explains for the 10th time* </code></pre> </div> <p><strong>After ContextVault</strong> (week 3 of a project):<br> </p> <div class="highlight js-code-highlight"> <pre class="highlight plaintext"><code>You: "Fix the auth bug" Claude: "I see from P001_auth.md that you're using JWT with 15min expiry and Redis for refresh tokens. Checking P005_error_jwt.md for recent issues..." </code></pre> </div> <h2> Getting Started </h2> <div class="highlight js-code-highlight"> <pre class="highlight shell"><code><span class="c"># 1. Install globally</span> curl <span class="nt">-sL</span> https://ctx-vault.com/install | bash <span class="c"># 2. Initialize in your project</span> /ctx-init <span class="c"># 3. Auto-document your codebase</span> /ctx-bootstrap <span class="c"># 4. Work normally — ContextVault captures knowledge</span> <span class="c"># 5. Next session — Claude remembers everything</span> </code></pre> </div> <h2> Why I Built This </h2> <p>I was tired of:</p> <ul> <li>Re-explaining my project architecture every few days</li> <li>Losing important bug fix context after long conversations</li> <li>Watching Claude forget decisions we made together</li> </ul> <p>Inspired by concepts from recursive language models (arxiv:2512.24601), I wanted Claude to have <strong>persistent memory that survives everything</strong> — new sessions, compaction, token limits, time.</p> <p>ContextVault is:</p> <ul> <li> <strong>100% local</strong> — Your data stays on your machine</li> <li> <strong>100% free</strong> — No subscriptions, no cloud fees</li> <li> <strong>Open source</strong> — MIT license, fork it, modify it</li> <li> <strong>Simple</strong> — Just markdown files</li> <li> <strong>Portable</strong> — Commit your vault to git, share with team</li> </ul> <h2> Not Like Other Solutions </h2> <p>Unlike paid "AI memory" services:</p> <ul> <li> <strong>No monthly fees</strong> — Free forever</li> <li> <strong>No cloud storage</strong> — Your data never leaves your machine</li> <li> <strong>No vendor lock-in</strong> — It's just markdown files</li> <li> <strong>No privacy concerns</strong> — 100% local</li> </ul> <h2> Links </h2> <ul> <li> <strong>Website</strong>: <a href="https://ctx-vault.com" rel="noopener noreferrer">ctx-vault.com</a> </li> <li> <strong>GitHub</strong>: <a href="https://github.com/ahmadzein/ContextVault" rel="noopener noreferrer">github.com/ahmadzein/ContextVault</a> </li> <li> <strong>Docs</strong>: <a href="https://ctx-vault.com/docs" rel="noopener noreferrer">ctx-vault.com/docs</a> </li> </ul> <p>If you use Claude Code, give ContextVault a try. Your future self will thank you when Claude remembers that obscure bug fix from three weeks ago — even after context compaction, token limits, and new sessions.</p> <p><strong>Star on GitHub if you find it useful!</strong> ⭐</p> <p><em>What's your biggest frustration with AI context loss?
