Knowledge Librarian (knowledge-librarian.yaml)

.github/workflows/knowledge-librarian.yaml is the workflow named “Knowledge Librarian”. A header comment says that it runs a scheduled LLM librarian that keeps .lokf/ in step with the repository, and opens a review pull request with whatever changed.¹ It never pushes to the default branch and never merges. It runs every Monday at 05:00 UTC and by hand, and it is inert until the repository variable KNOWLEDGE_LIBRARIAN_ENABLED is true. NOTICE says that it is a copy of a ktl-sidecar template from the Knowledge Trust Ladder repository.²

Its three jobs

• earlier reads what became of the pull requests the workflow opened before, with pull-requests: read only and no agent. While one is still open, a scheduled run opens no second one, and it does not propose again what a person declined by closing one without merging.
• refresh runs the agent under a read-only token with no git credentials on disk, with contents: read and copilot-requests: write, in the knowledge-librarian Environment. It installs the ktl-librarian skill from the tag that TRUST_LADDER_SKILLS_REF names, v0.57.0, and stops unless that tag names the commit that TRUST_LADDER_SKILLS_SHA gives, e7ec838780e9bc436970055a3cd5a5695015def6. A check after the run fails if the agent wrote anything but .lokf/patch.yaml, which the wrapper .lokf/scripts/knowledge-librarian.sh then applies.
• publish holds contents: write and pull-requests: write, runs no agent code, and pushes the branch and opens the pull request when refresh changed something.

Settings it reads

The agent command comes from repository settings. AGENT_CLI names it, and AGENT_API_KEY_ENV names the variable its credential goes in: COPILOT_GITHUB_TOKEN for Copilot CLI, or ANTHROPIC_API_KEY for Claude Code. Either AGENT_USE_JOB_TOKEN set to true or the AGENT_API_KEY secret supplies the credential. When KNOWLEDGE_RETRIEVAL is true, each run that changes the bundle scores whether the index leads the agent to the concept behind each question readers asked, at the cost of one more agent call. A scheduled week with nothing waiting for the librarian runs no agent, except in a month’s first seven days.

CHANGELOG.md says that the sidecar automation comes from the KTL v0.58.0 templates with the lokf floor at 0.9.0, and that the librarian’s skills pin, which those templates leave at v0.57.0, moves at the first weekly sync.³ CONTRIBUTING.md says that the skills pin moves with the sidecar copies, as Knowledge sync moves them. AI covenant sets the rules that the agent’s changes follow.
