feat: #173 — wrap_json_envelope() applied to all 13 clawable commands (LOOP CLOSED)
Completes the coverage → enforcement → documentation → alignment cycle.
Every clawable command now emits the canonical JSON envelope per SCHEMAS.md:
Common fields (now real in output):
- timestamp (ISO 8601 UTC)
- command (argv[1])
- exit_code (0/1/2)
- output_format ('json')
- schema_version ('1.0')
13 commands wrapped:
- list-sessions, delete-session, load-session, flush-transcript
- show-command, show-tool
- exec-command, exec-tool, route, bootstrap
- command-graph, tool-pool, bootstrap-graph
Implementation:
- Added wrap_json_envelope() helper in src/main.py
- Wrapped all 18 JSON output paths (13 success + 5 error paths)
- Applied exit_code=1 to error/not-found envelopes
- Kept text mode byte-identical (backward compat preserved)
Test updates:
- 3 skipped common-field tests now pass automatically
- 3 existing tests updated to verify common envelope fields while preserving command-specific field checks
- test_list_sessions_cli_runs, test_delete_session_cli_idempotent,
test_load_session_cli::test_json_mode_on_success
Full suite: 179 → 182 passing (+3 activated from skipped), zero regression.
Loop completion:
Coverage (#167-#170) ✅ All 13 commands accept --output-format
Enforcement (#171) ✅ CI blocks new commands without --output-format
Documentation (#172) ✅ SCHEMAS.md defines envelope contract
Alignment (#173 this) ✅ Actual output matches SCHEMAS.md contract
Example output now:
$ claw list-sessions --output-format json
{
"timestamp": "2026-04-22T10:34:12Z",
"command": "list-sessions",
"exit_code": 0,
"output_format": "json",
"schema_version": "1.0",
"sessions": ["alpha", "bravo"],
"count": 2
}
Closes ROADMAP #173. Protocol is now documented AND real.
Claws can build ONE error handler, ONE timestamp parser, ONE version check
instead of 13 special cases.
