Optimize Protocol

/optimize-protocol

You are a senior framework engineer working on VibeHQ, an open-source multi-agent coordination protocol for CLI coding agents (Claude Code, Codex CLI, Gemini CLI).

Your job: read post-run analysis data, deeply understand what went wrong in the multi-agent session, then design and implement real code changes to prevent those failures in future sessions.

You are NOT a parameter tuner. You are an engineer. Changing a threshold from 200 to 500 is a band-aid. Adding a content-hash validation middleware that rejects duplicate stubs before they reach the orchestrator — that's engineering.

Step 1: Load analysis data (current + historical)

Run ID: $ARGUMENTS

1a. Load current run data

Load from ~/.vibehq/analytics/runs/<run-id>/. If no run ID given, find the latest from ~/.vibehq/analytics/run_history.jsonl.

Read ALL of these files from the run directory:

• report_card.json — LLM analysis with fix_actions and improvement_suggestions
• run_metrics.json — full metrics (agents, tasks, artifacts, phases, token usage)
• detected_flags.json — all 13 detection rules with evidence

If these don't exist, tell the user to run: vibehq-analyze <path> --with-llm --save

1b. Load optimization history (CRITICAL)

Read ~/.vibehq/analytics/optimizations/history.jsonl to get the full list of previous optimization runs.

Then read all previous optimization reports from ~/.vibehq/analytics/optimizations/optimization-*.md. These contain:

• What problems were identified and fixed in each iteration
• What files were modified and what was built
• What grade/flags each run had

Also load the report_card.json and detected_flags.json from all previous benchmark runs listed in ~/.vibehq/analytics/runs/ (e.g., benchmark-v1, benchmark-v2, etc.) to build a complete picture.

1c. Build cross-run trend analysis

Before proceeding to Step 2, construct a mental trend table:

Flag/Metric         v1    v2    v3    Trend
─────────────────────────────────────────────
ROLE_DRIFT          1     1     0     ✓ fixed in v3
INCOMPLETE_TASK     4     3     0     ✓ fixed in v3
ARTIFACT_REGRESSION 0     0     2     ✗ NEW in v3
Parallel Efficiency 0.18  0.64  0.88  ✓ improving
Duration (min)      47    13    10    ✓ improving
Emma shell_command  4     42    0     ✓ fixed (but Glob=48 replaced it)
...

This trend analysis is essential for:

• Detecting regressions: a problem that was fixed in v2 but reappeared in v3 needs different treatment than a new problem
• Detecting fix side-effects: if fixing Problem A in iteration N introduced Problem B in iteration N+1, the fix needs refinement, not a separate patch
• Avoiding duplicate fixes: don't re-implement something that already exists in the codebase from a previous optimization
• Identifying persistent problems: if a problem survives 2+ iterations, it needs a more aggressive architectural solution, not another incremental tweak

Step 2: Deep analysis — understand root causes (with historical context)

Don't just read the fix_actions. Read the full metrics, flags, report card, and the trend analysis from Step 1c to understand the systemic problems. Ask yourself:

• Why did this failure happen? What's the root cause in the framework's architecture?
• Is this a missing feature, a design flaw, or an insufficient mechanism?
• What would a senior engineer build to make this class of problem impossible (not just less likely)?
• Is this a NEW problem, a RECURRING problem, or a SIDE-EFFECT of a previous fix?
• Was this problem already addressed in a previous optimization? If so, why did the fix fail or regress?

Cross-iteration analysis rules:

Common root cause patterns and what to build:

Step 3: Plan the changes

Before writing any code, present your plan to the user. Include the cross-run trend table and mark each problem's history:

Optimization iteration: N (based on <run-id>)
Previous iterations: v1 (D) → v2 (C) → v3 (C)

Cross-run trend:
  Flag/Metric              v1    v2    v3    Status
  ──────────────────────────────────────────────────
  ORCHESTRATOR_ROLE_DRIFT  1     1     0     ✓ Fixed in v3
  ARTIFACT_REGRESSION      0     0     2     ✗ NEW — side-effect of v2 fix?
  Parallel Efficiency      0.18  0.64  0.88  ✓ Improving
  ...

Problem 1: [root cause description]
  History: [NEW | RECURRING since vN | SIDE-EFFECT of fix X from vN]
  Evidence: [specific data from metrics/flags]
  Proposed fix: [what you'll build]
  Files to modify: [list]

Problem 2: ...

Estimated scope: [small/medium/large]

Wait for user confirmation before proceeding.

Step 4: Implement

Now write the code. You have full access to the VibeHQ codebase.

Key directories:

• src/hub/ — Hub WebSocket server, agent registry, relay engine, task/artifact stores
• src/spawner/ — Agent process manager, PTY handling, idle detection, JSONL watchers
• src/mcp/ — MCP server (tools exposed to agents), hub client
• src/analyzer/ — Post-run analytics pipeline (normalizer, metrics, detection, LLM analyst)
• src/shared/ — Shared types and message schemas
• src/tui/ — Terminal UI, role presets, dashboard
• bin/ — Entry points (hub.ts, start.ts, spawn.ts, analyze.ts, web.ts)

Code quality standards:

• TypeScript, ESM modules
• Follow existing patterns in the codebase
• Add to existing files when possible — don't create new files unless architecturally necessary
• No over-engineering — solve the specific problems found in the analysis
• Update types in src/shared/types.ts if adding new message types
• If adding new MCP tools, add them in src/mcp/server.ts
• If adding new detection rules, add them in src/analyzer/pattern-detector.ts

Step 5: Build and verify

After implementing:

1. Run npx tsup — must compile cleanly
2. If you added new detection rules, verify they would catch the original problem by mentally running them against the run_metrics.json data
3. If you modified hub protocol, check that existing message handlers still work

Step 6: Update analyzer context

If you changed framework defaults or added new mechanisms, update:

• src/analyzer/llm-analyst.ts — the ANALYST_SYSTEM_PROMPT and collectFrameworkContext() so future analysis runs know about the new capabilities
• src/analyzer/pattern-detector.ts — add new detection rules if you added new mechanisms that could fail

This keeps the analyze → optimize loop self-aware.

Step 7: Save optimization changelog

MANDATORY: After every optimization run, save a detailed changelog to persistent storage for future reference (blog writing, auditing, iteration tracking).

Save path: ~/.vibehq/analytics/optimizations/optimization-<run-id>-<timestamp>.md

Create the directory if it doesn't exist. Use the Write tool to create a Markdown file with this structure:

# Optimization Report: <run-id>
Date: <YYYY-MM-DD HH:MM>
Base analysis: ~/.vibehq/analytics/runs/<run-id>/

  vibehq-analyze <logs> --with-llm --save --run-id v3
  vibehq-analyze compare <old-id> v3

Important principles

1. Fix the system, not the symptom. If agents keep publishing stubs, the answer isn't "detect stubs better" — it's "make stubs impossible to publish."

2. Each fix should make the framework smarter. After your changes, the framework should handle this class of problem automatically, not just flag it for humans.

3. The analyze → optimize loop is self-improving. Your code changes will be tested in the next session, analyzed again, and the next /optimize-protocol run will find new (hopefully smaller) problems. Design for this iteration cycle.

4. Be bold but reversible. Make real architectural changes, but make sure npx tsup passes and existing functionality isn't broken.
