Reliability & compatibility
Declared compatibility
Compatibility is declared by the source manifest. End-to-end runtime verification is coming, see below.
We're building live execution health for every listing: tool-call success rate, median latency, uptime, and last-checked timestamps, measured, not self-reported. It isn't live yet, so we don't show numbers we can't stand behind.
How agent discovery & health will work →About
TDD Cycle Runner Skill
Workflow
- Receive
start_cyclecontract from main orchestrator - For each phase:
- Load phase SKILL.md and asset files
- Execute phase guidance through the loaded phase skill
- Route every RED, GREEN, and REFACTOR verification through
tdd-test-run
using an explicit expected-result contract before advancing the cycle
- Validate contract result
- On failure, escalate to main orchestrator
- On completion, return
cycle_completecontract
Decision Points
- If any phase fails, escalate immediately
- If all phases succeed, return cycle summary
Quality Criteria
- Only minimal context passed to each phase
- All contract handoffs validated
- No direct communication with main orchestrator by phase skill executions
- Progressive disclosure enforced
- Any rollback after a failed verification is limited to the scoped files named
in the test_run_request contract
Completion Checks
- All contracts for the cycle are satisfied
- All phase outputs are validated
- Escalation path is tested
