glas-harness

glas-harness is the primary execution-layer abstraction for governed agent work. Consumers select a versioned Glas profile; Glas resolves the concrete rein, model route, sandbox profile, tool policy, and limits, runs the outer lifecycle, and returns one normalized evidence envelope.

The consumer contract does not name a Python rein class or provider CLI:

assignment / channel / activity
  -> ExecutionRequest(harness_profile_ref=...)
  -> Glas profile resolution
  -> rein + model + sandbox + tool policy
  -> normalized ExecutionEvidence

Profiles

List and validate every committed executable profile:

glas-harness profiles
glas-harness profiles --json

Current constellations include:

harness.agent-dev-local@1.0.0: rein-aharness, Claude Code model route, local bwrap sandbox.
harness.agent-dev-openweights-local@1.0.0: rein-openweights, OpenRouter open-weight route, local bwrap sandbox.
harness.agent-dev@1.0.0: rein-aharness, remote agent-dev sandbox.

Run a task through an explicit profile:

glas-harness run \
  --harness-profile harness.agent-dev-local@1.0.0 \
  --repo /absolute/path/to/repo \
  --title "Bounded change" \
  --description "Make the requested change and commit it"

There is no governed default rein, model, sandbox, or tool profile. Unknown, disabled, incompatible, and ambiguous selections are refused before sandbox creation.
