Closes #5

Summary

Issue #5 asks whether multiple Claude agents can work on a project at the same time to finish it faster. They already can. The unified orchestrator (parallel_orchestrator.py) runs up to 5 concurrent coding agents. It hands features out atomically and schedules by dependency. You can turn it on with --concurrency N or the concurrency slider in the UI. The problem is that it was barely documented, and what docs existed pointed at the wrong flags.

Changes

• README.md: new Parallel Agents (Finish Projects Faster) section, covering:
  • the UI slider and Mission Control
  • CLI examples
  • a flag table (--concurrency, --batch-size, --testing-ratio, --testing-batch-size)
  • caveats: token/rate-limit cost, dependency-graph limits, the shared working directory, process caps
• CLAUDE.md: replaced flags that autonomous_agent_demo.py does not accept:
  • --parallel --max-concurrency 3 → --concurrency 3
  • --batch-features → --feature-ids
  • --testing-batch-features → --testing-feature-ids
• parallel_orchestrator.py: comments and help text only.
  • Fixed the stress-test comment's command.
  • The --batch-size / --testing-batch-size help said 1-5, but the code clamps to 1-15. The help now says 1-15.

Verification

• Every documented flag was checked against the argparse definitions, and parse_args() was run with the documented flag combination. They all parse.
• Each documented claim was checked against the code: clamps (max_concurrency 1-5, ratio 0-3, batches 1-15), YOLO skipping testing agents, per-agent PLAYWRIGHT_CLI_SESSION, and the slider range in AgentControl.tsx.
• ruff check . passes and python test_security.py passes.
• There are no UI code changes, so I did not do a browser check.

Assumptions

• The issue is a question about a capability that already exists, so better documentation resolves it; no new feature code is needed.
• The 2–3 agent starting recommendation in the README is my own guidance, not something the code enforces.

This docs-only PR adds an accurate README section on parallel agents (--concurrency, the UI slider, batching, caveats). It replaces the stale CLI flags in CLAUDE.md and the orchestrator comment and help text with ones the parser accepts, which resolves the question in issue #5. I parsed every documented command with the real argparse (all accepted) and confirmed the old flags are rejected. I checked each claim against the code and saw the slider in the running UI. ruff, the security tests and the UI build pass, and pytest and mypy match master apart from local-environment noise. Non-blocking: the README calls --testing-ratio 'per coding agent', but the code runs a fixed number of testing agents (0-3) regardless of concurrency, and '5 coding + 5 testing' overstates testing agents, which top out at 3. This wording is inherited from the existing --help text and CLAUDE.md and worth correcting in a follow-up.

	Check	Details
✅	Issue #5 answered: parallel agents documented	The README has a new 'Parallel Agents' section covering the UI slider, Mission Control, CLI examples, a flag table and caveats. It matches the existing orchestrator behaviour.
✅	Documented CLI flags parse	I ran autonomous_agent_demo.parse_args() on all 7 documented commands plus the -c alias and --parallel 3: all parsed, with the expected values.
✅	Old flags really were broken	--parallel --max-concurrency 3, --batch-features and --testing-batch-features all fail with 'unrecognized arguments' (exit code 2), which confirms the CLAUDE.md fixes.
✅	Claims match the code	The code clamps max_concurrency to 1-5, testing ratio to 0-3 and batch sizes to 1-15 (so the --help 1-5 -> 1-15 fix is correct). YOLO mode skips testing agents, each agent gets its own PLAYWRIGHT_CLI_SESSION, MAX_TOTAL_AGENTS is 10, and the slider in AgentControl.tsx runs 1-5 and saves default_concurrency per project. Minor wording issue: testing ratio is a fixed number of testing agents, not 'per coding agent' (_maintain_testing_agents uses desired = testing_agent_ratio). The wording is inherited from the existing help text, so I did not block on it.
✅	Stress-test comment command	The new autonomous_agent_demo.py --project-dir test --concurrency 5 parses. The docstring line using parallel_orchestrator.py --max-concurrency is correct for that script, which does define the flag.
✅	Python lint/tests	ruff is clean and test_security.py passes 169 tests. pytest shows 21 failures, identical on master in the same environment. mypy reports 25 errors vs 24 on master; the extra one is in the local venv/activate_this.py, not in the PR.
✅	UI build + browser check of documented slider	The UI build succeeds. I booted the server on 127.0.0.1:5443 with an isolated HOME and test project; /api/health returns healthy. The dashboard shows the branch-icon concurrency slider (3x) next to the start button, with no console errors. I stopped the server and port 5443 is free.
⏭️	UI lint / e2e	Skipped because the PR changes no UI code.
