How much Poka reads
B4 Summary. The container and metadata are read and summarised (counts, properties, structure), but the main content is not rendered.
Confidence: medium (the reviewer read the code). Basis: Reviewed 2026-10-26: read parsers/poka-cron/src/main.rs (278 lines) and plugin.json. No unit tests or tests/samples.rs; the corpus has no .cron sample. Covers .cron. The card counts 5-, 6- and 7-field entries, @-shortcuts, step values, environment lines and named users, with sample commands, malformed lines and line counts. Judgement: B4: the content is summarised by counts, but the entries themselves are not shown.
What Poka does not read
- The jobs are not listed (the .crontab module lists them)
- Schedules are not explained
- Only sample commands are shown
