What we do not know yet · 2 open gaps

  • Native, ACP, and terminal agents have different configuration paths.
  • Model access does not imply every external agent supports the same tools.

Applies to: Unpinned public documentation as of 2026-09-13 · Documentation review only

Applicability

Unpinned public documentation as of 2026-09-13

Documentation review only

Excludes: Runtime behavior; Performance comparisons; Security guarantees

Verification plan

  1. Pin a product release or repository commit and record the host environment.
  2. Create a disposable repository with a passing baseline test.
  3. Run a bounded change with two agents where supported; record permissions and logs.
  4. Record a failed attempt, actual outcome, and artifacts without secrets.
  5. Have another person reproduce the result before labeling it reproduced.

Capability claims · 18 / 46 sourced

Standing condition: these are documentation claims at the source capture date, with outcome “claimed”; no runtime execution is recorded. Dossier applicability and limitations apply throughout. Expand a row for its statement, specific scope and contradictions. Numbered citations resolve to the source locator and capture date below. Missing evidence means Unknown, not No. Sources are unpinned unless marked “Pinned”; this marks source stability, not stronger support or runtime verification. Reuse counts refer to claims in the full dossier; repeated citations do not represent independent sources.

Yes Documented within scope Partial Limited form of the feature No Explicit evidence of absence Unknown No evidence recorded. These are support assessments, not quality scores or runtime verification.
