01Result
PowerShell/PowerShell ↗PowerShell/PowerShell AI coding statistics: 12%
Adoption is broad. Many contributors are committing agent-authored work, which is what a real organisational rollout looks like.
02Drivers
What shapes this result
Mode, timing, and detected signatures show whether the result reflects broad adoption or one concentrated workflow.
Assisted or autonomous
Assisted — a developer’s identity authored the commit and the agent added itself as co-author. Autonomous — a bot identity authored the commit without a human identity attached. Across the whole index, 96% of agent commits are assisted.
Agent share by month

| 2026-03 | 15.4% | 26 |
| 2026-04 | 7.7% | 26 |

| 2026-08 | 3% | 33 |
| 2026-09 | 15% | 20 |
Peak month: 21.4%. Bars are scaled to that peak, not to 100%.

04Method
What entered the denominator
The result begins with commit history, removes merges and routine automation, and reports literal agent signatures as a lower bound.
Exclusion ledger
| Commits in window | 210 |
| Merge commits removed | −3 |
| CI / dependency bots removed | −16 |
| Considered | 191 |
Bots are excluded from the denominator entirely. Agent attribution requires a literal supported signature; no code-style inference is used.
05Provenance
Pinned to a source state
This observation names the repository state, release, and detector that produced it. Use these identifiers when reproducing or citing the result.

06Peer context
Position among comparable repositories
The cohort uses the same release and measurement window, then narrows to the repository’s ecosystem and removes low-activity observations.
Midrank percentile; equal shares split the tied positions.
- Repository
- 12%
- Cohort median
- 2.1%
- Share rank
- 7 / 21
Percentile = (repositories below + half of 1 tied repository) ÷ 21.

Deterministic signature matching; no code-style inference. Squash merges can remove trailers, so this result remains a measured floor.
