What problem does it solve? Running and debugging automated Salesforce org builds with prepare_rlm_org involves long-running scenarios, transient failures, and scattered artifacts. This Skill provides the commands, artifact locations, resume rules, and safety policies needed to operate the local build harness CLI and the CCI Build Manager TUI without guesswork. ## Core Features & Use Cases - Scenario-based profiling runs: Execute dev/ent default and lightweight scenarios from scripts/build_harness/scenarios.json with run, resume, report, and prune commands, including JSON output mode for agent automation. - Checkpoint resume and failure classification: Resume failed scenarios from checkpoint.json with flag-consistency checks, exit codes, and transient/deterministic failure signatures plus recommended actions in run_summary.json. - Guided scratch org creation via TUI: Launch the Textual-based CCI Build Manager with ./tui-cci, confirm shape/days/alias defaults with the user, and monitor builds with per-run cci_project materialization. - Use Case: A build fails mid-scenario on a network timeout. Inspect .harness/runs/<run_id>/ artifacts, confirm the failure is transient, then run the resume command with the same scenario flags to continue from the failed step instead of rebuilding from scratch. ## Quick Start Ask the agent to run the build harness for the ent-default scenario and report the results from the generated run artifacts.
