<h1>v0.4.20: Multi-Agent Targeting and Input/Output Savings Split</h1>
<p class="subtitle">Target specific AI coding agents with <code>--agent</code>, see accurate cost savings split by input and output tokens, and get reliable upgrade version detection.</p>

<h2>Target the agent you actually use</h2>
<p><code>cce init</code> has always auto-detected your editor. That works well when you have Claude Code installed. But if you only use Codex, or only use Copilot, auto-detection could miss your setup or write config files you don't need.</p>
<p>Now you can be explicit:</p>

<pre>cce init --agent codex # Codex only: ~/.codex/config.toml + AGENTS.md
cce init --agent copilot # VS Code only: .vscode/mcp.json + .github/copilot-instructions.md
cce init --agent claude # Claude only: .mcp.json + CLAUDE.md
cce init --agent all # Every supported editor
cce init # Auto-detect (same as before)</pre>

<p>Each flag writes exactly what that agent needs. No surprise edits to files belonging to other editors.</p>

<h3>What gets written</h3>
<table>
<thead>
<tr><th>Flag</th><th>MCP config</th><th>Instruction file</th></tr>
</thead>
<tbody>
<tr><td><code>--agent claude</code></td><td><code>.mcp.json</code></td><td><code>CLAUDE.md</code></td></tr>
<tr><td><code>--agent codex</code></td><td><code>~/.codex/config.toml</code></td><td><code>AGENTS.md</code></td></tr>
<tr><td><code>--agent copilot</code></td><td><code>.vscode/mcp.json</code></td><td><code>.github/copilot-instructions.md</code></td></tr>
<tr><td><code>--agent all</code></td><td>All of the above + Cursor, Gemini, OpenCode, Tabnine</td><td>All instruction files</td></tr>
</tbody>
</table>

<p><code>--agent all</code> is computed from the editor registry at runtime. When new editors are added to CCE, <code>all</code> picks them up automatically.</p>

<h2>Input and output savings, split correctly</h2>
<p>Before this release, <code>cce savings</code> priced everything at the input token rate. That was wrong. Output tokens cost 5x more than input tokens on Opus ($75/1M vs $15/1M). A small output savings is worth more in dollars than a large input savings.</p>

<p>The savings report now splits these correctly:</p>

<pre> Input savings 8.6k tokens $0.13
Output savings 325 tokens $0.02
──────────────────────────────────────────
Total saved 8.9k tokens $0.15
~4.5k tokens / query ~$0.08 / query

Breakdown:
retrieval 48% ▰▰▰▰▰▰▰▰▰▰ 6.0k $0.09 · 1 call
chunk compression 20% ▰▰▰▰▱▱▱▱▱▱ 2.6k $0.04 · 1 call
output compression* 2% ▰▱▱▱▱▱▱▱▱▱ 325 $0.02 · 1 call

Cost estimate based on Opus pricing (input $15/1M, output $75/1M)</pre>

<p>The pricing module now fetches both input and output rates from the Anthropic docs page. Old cache files from previous versions are migrated automatically.</p>

<h2>Upgrade version detection fix</h2>
<p><code>cce upgrade</code> had a bug where it always reported "Already on latest version" even after a successful upgrade. The running process couldn't see the new version metadata because <code>uv tool upgrade</code> installs into a separate virtual environment.</p>
<p>The fix: after upgrading, CCE shells out to the upgraded binary with <code>--version</code> to read the real post-upgrade version. Simple, reliable.</p>

<h2>Upgrade</h2>

<pre>cce upgrade</pre>

<p>Or manually:</p>

<pre>uv tool upgrade code-context-engine</pre>

<div class="callout">
<p><strong>Existing projects:</strong> Run <code>cce init --agent all</code> if you want to add instruction files for Codex and Copilot. Your existing <code>CLAUDE.md</code> and <code>.mcp.json</code> will be preserved.</p>
</div>

<h2>Full changelog</h2>
<ul>
<li><strong>feat:</strong> <code>cce init --agent {auto,claude,codex,copilot,all}</code> for explicit agent targeting</li>
<li><strong>feat:</strong> New instruction file targets: <code>AGENTS.md</code> (Codex) and <code>.github/copilot-instructions.md</code> (Copilot)</li>
<li><strong>feat:</strong> Savings report splits input and output token savings with correct per-type pricing</li>
<li><strong>feat:</strong> Pricing module tracks both input and output rates per model family</li>
<li><strong>fix:</strong> <code>cce upgrade</code> now correctly detects the post-upgrade version</li>
<li><strong>fix:</strong> Claude-only setup (session hooks, memory hooks) skipped when targeting non-Claude agents</li>
</ul>
