Not accurately reporting usage for OpenCode

[chimon2000]

Currently, Codeburn doesn't accurately compute the MCP usage for Opencode. See the following output from optimize:

─── 4. 2 MCP servers configured but never used ───────── Medium ───

  Never called in this period: clickup, figma. Each server
  loads ~2000 tokens of tool schema into every session.

  Potential savings: ~660.0K tokens (~$0.139)

  -- Run this command ────────────────────────────────────  
  Remove unused servers:
    claude mcp remove clickup
    claude mcp remove figma

As well as from just using codebun command:

╭─────────────────────────────────────────────────────────────────────────────────────╮
│ MCP Servers                                                                         │
│ No MCP usage                                                                        │
╰─────────────────────────────────────────────────────────────────────────────────────╯

Here is a previous session from OpenCode, proving the use of the clickup mcp:

Thinking: The user wants me to look at a ClickUp task. Let me fetch the task details using the ClickUp tools.
⚙ clickup_clickup_get_task [task_id=*-3210]

Expected behavior

Codeburn commands accurately report MCP server usage and recommendations for removing servers.

Implemented in PR #309: #309

Root cause: OpenCode records MCP calls as <server>_<tool> part names, for example clickup_clickup_get_task, while CodeBurn's shared MCP reporting path only counts canonical mcp__<server>__<tool> names. Because the OpenCode provider was passing the raw name through, the parser treated ClickUp/Figma calls as ordinary tools and never populated mcpBreakdown, which led to No MCP usage and false optimize removal suggestions.

The fix normalizes OpenCode external tool calls before aggregation:

clickup_clickup_get_task -> mcp__clickup__clickup_get_task
figma_get_file           -> mcp__figma__get_file

Built-in OpenCode tools like bash, edit, and read still remain regular core tools. I also added focused regression tests for the ClickUp/Figma shape, already-normalized MCP names, no-prefix tool names, malformed underscore names, and the related MCP/optimize paths.

Validation:

• npm run build
• npx vitest run tests/providers/opencode.test.ts tests/mcp-coverage.test.ts tests/optimize.test.ts tests/optimize-fs.test.ts (4 files / 166 tests)
• npx vitest run (47 files / 665 tests)
• git diff --check
• Argus local reviewer: PASS
• Claude Opus 4.7 effort max: PASS
• Gemini 3.1 Pro Preview: PASS

Fix merged to main in #318. OpenCode MCP tool names are now normalized from <server>_<tool> to the canonical mcp__<server>__<tool> form before aggregation.

@chimon2000 could you test this against your ClickUp/Figma sessions? You can run from main:

git clone https://github.com/getagentseal/codeburn.git
cd codeburn && npm install
npx tsx src/cli.ts report --provider opencode
npx tsx src/cli.ts optimize --provider opencode

MCP Servers panel should now show your ClickUp and Figma usage, and optimize should stop recommending removal of servers you are actively using.

We will include this in the next npm release once you confirm it works.
