## What do Pi subagent extensions document in 2026?

This 2026 study contains 8 selected Pi subagent extension records in the [JSON dataset](https://subagentura.tech/pi-subagentura/statistics-2026/data.json)  and [CSV dataset](https://subagentura.tech/pi-subagentura/statistics-2026/data.csv) ; each row links to the pinned README or primary documentation revision reviewed on 2026-10-21. It counts documented mechanisms in this selection; it is not a market-size estimate, adoption survey, performance test, or complete directory.

Use the [full Pi subagent comparison](https://subagentura.tech/pi-subagentura/compare/)  for context, installation commands, and detailed project profiles. The [pi-subagentura npm and GitHub statistics](https://subagentura.tech/pi-subagentura/stats/)  are a separate dataset about one project's public service counters.

## How many Pi subagent extensions document in-process execution in 2026?

6 of 8 selected Pi subagent extensions document standard in-process child execution in their reviewed 2026 sources: [lmn451/pi-subagentura](https://github.com/lmn451/pi-subagentura/blob/644387d5a60db88aa07f743473dbb5b1993ad013/README.md)  ; [nicobailon/pi-subagents](https://github.com/nicobailon/pi-subagents/blob/80f8f79d51ee8075fd39baf7fe8ff36b43c3a790/README.md)  ; [tintinweb/pi-subagents](https://github.com/tintinweb/pi-subagents/blob/ca93a5247e72e7053fcd10bea7125d6c4205f949/README.md)  ; [gotgenes/pi-subagents](https://github.com/gotgenes/pi-packages/blob/41405de895fb53f802df89f8978456cd1dae397e/packages/pi-subagents/README.md)  ; [Integralist/pi-subagents](https://github.com/Integralist/pi-subagents/blob/37e9c2a02873bd9733971bd529f12e53d9d40112/README.md)  ; [AlexParamonov/pi-subagents-lite](https://github.com/AlexParamonov/pi-subagents-lite/blob/0a3fb576416398995d82ebc6ecd7f1cb5b5ea2de/README.md)  .

1 of 8 selected extensions documents an experimental parent-local inline-worker path in its 2026 source, while describing separate Pi processes as the normal delegation mode: [mjakl/pi-subagent](https://github.com/mjakl/pi-subagent/blob/77cc8be9a4257c00643f328d461a7ab2c1490686/README.md)  .

1 of 8 selected extensions has no in-process execution path documented in the reviewed 2026 source; that source describes Pi sessions in multiplexer panes: [HazAT/pi-interactive-subagents](https://github.com/HazAT/pi-interactive-subagents/blob/c100577ebf7393a11d098ad9810ec6c269dcfc30/README.md)  .

## How many Pi subagent extensions document attachable terminals in 2026?

2 of 8 selected Pi subagent extensions explicitly document attachable child-terminal sessions in their 2026 sources: [lmn451/pi-subagentura](https://github.com/lmn451/pi-subagentura/blob/644387d5a60db88aa07f743473dbb5b1993ad013/README.md)  ; [HazAT/pi-interactive-subagents](https://github.com/HazAT/pi-interactive-subagents/blob/c100577ebf7393a11d098ad9810ec6c269dcfc30/README.md)  .

“Not documented” in the table means the reviewed source did not explicitly describe entering an attachable child terminal; it does not establish that a project cannot support one.

## Which terminal environments do Pi subagent projects name in 2026?

The 2026 documentation for 8 selected Pi subagent extensions names 5 supported terminal or multiplexer environments across 2 projects: cmux, Herdr, tmux, WezTerm, Zellij.

## Which eight Pi subagent projects are in this 2026 study?

Each row records how the reviewed source describes the project; the linked revision is the evidence for that row. A “not-documented” value marks an evidence limit, not a negative feature claim.

## How was the 2026 Pi subagent documentation study assembled?

The 8-project sample is purposive: it consists of the eight projects selected for the companion comparison, rather than a random or exhaustive sample of Pi extensions. The publisher of this study also publishes pi-subagentura, which is included in the sample; that is a direct conflict of interest.

Each classification was transcribed from the source revision linked in its row and reviewed 2026-10-21. Git commit hashes pin every source, including the npm v4.0.1 source commit for pi-subagentura; a README can describe repository code that is newer than the latest package available from a package registry.

“Standard” means the source describes in-process child execution as an ordinary supported path. “Experimental” preserves the source’s explicit experimental label. A boolean terminal value is positive only when an attachable terminal is explicitly documented; “not documented” is not treated as “unsupported.” Worktree categories distinguish built-in or workflow creation, a companion package, and an explicitly documented worktree-path control. Generic working-directory overrides such as pi-subagentura’s cwd are not counted as a dedicated worktree feature; they can still point to a checkout the caller prepared.

The counts describe documentation in this selected sample as of the review date. They do not estimate extension market share, usage, project quality, performance, reliability, or the full set of available Pi tools.
