leji (Python)

Reference SDK and CLI for the Leji specification: the open specification for the shared context layer of AI-native teams.

pip install leji        # or: uv tool install leji / pipx install leji
leji init               # bootstrap a context layer interactively
leji validate           # manifest, artifacts, frontmatter, lint rules
leji index              # generate the context index
leji index --check      # fail when the index is stale
leji changelog check    # append-only discipline
leji freshness          # review-horizon report
leji conformance        # score the layer against its claimed level
leji status             # unindexed, dangling, and stale documents
leji route              # the governed context a task's scope routes to
leji viewer             # generate the static viewer for the context layer
leji viewer build       # export a self-contained static viewer folder
leji viewer serve       # generate, then serve it locally
leji view               # generate, serve, and open it in your browser
leji detect             # find installed agent hosts
leji start              # open the layer in a detected agent host
leji adopt              # map an existing entrypoint into a context layer
leji ci                 # add a validate workflow (--provider github|gitlab|circleci|azure)
leji agent --name <n>   # bind an additional named agent into the layer
leji mounts hydrate     # materialize declared federation mounts into the resolver cache
leji mounts status      # each mount's availability, integrity, and pin ancestry
leji mounts locate      # resolver state for one mount: projection path, pin, verification
leji changelog compact  # fold the oldest changelog entries into one compaction entry

See the full command reference (flags, exit codes, examples) at https://leji.org/cli/.

Behaviorally identical to the @leji-org/leji npm package and the Go SDK: same commands, same flags, same findings, same exit codes (0 clean, 1 findings, 2 usage error). All three implementations are tested against one shared fixture suite. Install whichever matches your toolchain; agents and CI see the same tool either way.

Supports spec line 1.0. Schemas and templates for that line ship inside the package; no network access is needed.
