Outcome

Local installs can display provider-native usage information when JSONL data is not enough.

Scope

Add parser module under backend/app/services/openclaw/usage_scrapers.py (or extend runtime_usage.py)
Add schemas to backend/app/schemas/runtime_usage.py
Add optional endpoints near the Batch 1 route
Add test fixtures for parser samples

Implementation Details

Optional adapter interface: RuntimeUsageProviderAdapter
Port Claude /usage parser behavior into Python (tests first)
Tmux scraping is opt-in, disabled by default
Store scraper output under MC-managed cache location, not arbitrary workspace writes
Add last-scraped time, source name, and freshness indicators
Gemini usage scrape hooks: design provider hooks, implement only when data present

Risk

CLI text output changes often — keep as supplemental, not primary accounting source
Provider-specific adapters should be isolated and easy to disable

Reference

scripts/scrape-claude-usage.sh: tmux session lifecycle, /usage invocation, lock file, output cache
scripts/parse-claude-usage.py: parser for current session percent, remaining time, weekly fields
server.js: /api/claude-usage-scrape, /api/claude-usage, /api/gemini-usage-scrape, /api/gemini-usage

Depends On

#30 (Batch 1: Read-only Usage Core)

Verification Complete ✅

Batch 3 scope verified against existing implementation.

What the issue requested:

Parser module under backend/app/services/openclaw/usage_scrapers.py ✅
Schemas in backend/app/schemas/runtime_usage.py ✅
Optional endpoints near Batch 1 route ✅
Test fixtures for parser samples ✅
Optional adapter interface RuntimeUsageProviderAdapter ✅
Port Claude /usage parser behavior into Python (tests first) ✅
Tmux scraping opt-in, disabled by default ✅
Store scraper output under MC-managed cache location ✅
Gemini usage scrape hooks (design provider hooks) ✅ (via adapter interface)

Existing implementation:

Component	Status	Notes
`usage_scrapers.py`	✅ Complete	Full provider adapter interface, ClaudeTmuxScraper, parse_claude_usage() with 12+ test fixtures
`runtime_usage.py` schema	✅ Complete	ProviderUsageScrapeResult and ProviderUsageResponse added
API endpoint	✅ Complete	`GET /gateways/{id}/provider-usage` in gateways.py
Tests	✅ Complete	test_runtime_usage_scrapers.py with 27+ assertions
Opt-in config	✅ Complete	USAGE_SCRAPER_ENABLED=false by default
Cache location	✅ Complete	UsageScraperCache stores under /tmp/pipeline-usage-cache by default
Issue #30 dependency	✅ Met	Batch 1 runtime-usage endpoint exists

Risk notes captured in code:

CLI text output changes often → kept as supplemental, not primary accounting source ✅
Provider-specific adapters isolated and easily disabled ✅
tmux requirement documented in adapter class docstring ✅

Result: Issue #32 scope matches implementation. Ready for implementation tracking.
