-Provide either an input string or an input file; the library has no sample
input by default and does not fetch logs from another Jenkins job. To supply
live data, gather a small, sanitized summary in the dedicated job and pass it
as `llmaoInput`. The library allocates its own node and checks out the project;
`llmaoInputFile` must exist in that checked-out workspace. Input files are not
deleted. Avoid sending secrets or large logs, and check the Models page for who

+Provide either an input string or an input file; the library has no default
task. The library allocates its own node and checks out the project;
`llmaoInputFile` must exist in that checked-out workspace. Input files are not
deleted. The checkout must be clean before Pi starts, so existing changes are
never silently discarded. Avoid exposing secrets to the agent, and check the
Models page for who can see prompts and source files.
-The library runs [Pi](https://pi.dev) in Docker as a non-interactive LLM
client. Pi is configured for LLMAO's OpenAI-compatible endpoint at
`https://llm.apache.org/v1`, with the selected model and temperature `0.0`. The
existing system prompt and input are passed to Pi, with tools, extensions, MCP,

+The library runs [Pi](https://pi.dev) in Docker, configured for LLMAO's
OpenAI-compatible endpoint at `https://llm.apache.org/v1`, with the selected
model and temperature `0.0`. Pi can read, search, edit, and write project files
and run shell commands. Extensions, MCP, automatic project instructions, stored
sessions, retries, and compaction remain disabled.
-An exact `RETRY` is reported without retrying the normal project build; `FIX`
or an ambiguous answer marks only the LLMAO job unstable. Empty answers, Pi
errors, HTTP/network errors, and timeouts fail the LLMAO job. Generated
input/configuration files are cleaned up, and raw prompts/responses are not
archived or printed.
+Each run fetches `skills/` from the `master` branch of [Apache Sling
Whiteboard](https://github.com/apache/sling-whiteboard/tree/master/skills),
including references and scripts. All its skills are explicitly available to
Pi, including `update-sling-parent-pom`. The fetched Git revision is logged.
Skills live outside the project checkout and do not appear in the diff. The
parent-POM skill currently targets the latest supported release, not simply the
current version plus one.
+
+Pi is instructed to respond only with `SUCCESS` after completing and verifying
its update, or `FAILURE` otherwise, without staging, committing, pushing,
switching branches, or altering Git metadata. The wrapper maps an exact
`SUCCESS` and a successful Pi process to exit code `0`; `FAILURE`,
empty/malformed answers, or execution errors return a nonzero exit code and
fail the Jenkins job. The final response is kept separate from diff output, so
strings in the diff cannot be mistaken for an [...]

+The resulting Git diff is printed to stdout in the Jenkins build log,
including partial changes on failure and new, non-ignored files without staging
them. Project edits remain in the job workspace for inspection; no commit,
push, or automatic recovery is performed. Generated input/configuration files
are cleaned up, and sessions are not archived.
### Docker runtime
-The `ubuntu` agent needs a Unix shell and access to a **local Docker daemon**.
The daemon must see the executor's temporary workspace at the same absolute
path for the input bind mount; containerized executors must share that path
with the Docker host. The job also requires the Jenkins Pipeline Utility Steps
plugin (`writeJSON`/`readJSON`). No host Node.js, Pi installation, or Jenkins
Docker Pipeline plugin is required.

(`writeJSON`/`readJSON`). No host Node.js, Java, Maven, Pi installation, or
Jenkins Docker Pipeline plugin is required.
-The library builds `sling-llmao-pi:1.1.0-node24-d6aa754f` from its
[Dockerfile](resources/org/apache/sling/jenkins/llmao/Dockerfile), pinning the
official `node:24-bookworm-slim` image by digest and the
`@earendil-works/pi-coding-agent` package at version `1.1.0`. Docker's layer
cache avoids reinstalling Pi on subsequent runs on that executor. The first
uncached build needs access to Docker Hub and the npm registry; the running
container needs access to `llm.apache.org`.
