harn

Generate, validate, preview, and run portable Harn workflow bundle JSON for monitoring and repairing pull requests, deploys, logs, and other event-driven engineering work. Optimized for smaller models (qwen, gemma, llama.cpp) with explicit XML sections, strict JSON output, and a validation-and-retry loop.

Use for Harn language syntax, typechecking, modules, imports, and idiomatic script authoring.

Use for autonomous Harn agent work, task decomposition, capability boundaries, and host interaction patterns.

Use for Harn orchestration workflows, agent_loop usage, tool middleware, and handoff design.

Use for Harn provider setup, model routing, provider capability matrices, and llm_call options.

Run a cron eval pack, gate against prior ledger rows, and post Slack only on gate flips.

Demonstrates the same issue-triage handler behind local and remote A2A trigger manifests.

Stream trigger example for routing or grouping event batches.

Generic webhook recipe with signed inbound requests.

Use for maintainability audits and refactors across Harn code, especially duplicated orchestration, stringly or open dict contracts, silent fallbacks, oversized modules, repeated test harnesses, flaky waits, and hand-maintained tables that should have one typed owner.

Cut a Harn release through the merge queue. One PR carries CHANGELOG + Cargo.toml bump + regenerated artifacts; downstream tag push + binary build cascades fire automatically once it lands.

Bundled by an installed package generation

Use for Harn release prep, version bumps, publishing, tags, and release notes.

Final-polish pass on the current PR or feature branch before it lands. Rebases on origin/main, force-pushes, drives CI to green, then reviews the diff for correctness/perf/security/reliability bugs, flaky test patterns banned by `make lint-test-patterns`, sloppy comments a senior engineer would not write, cross-crate drift (typechecker / formatter / portal / DAP / LSP / tree-sitter), DRY/polish, Rust orchestration logic that should be Harn script composing host capabilities, prompt prose that belongs in `.harn.prompt` files, long files that should be split, and interpreter perf wins that bundle naturally with the change. Triggers when the user says "finish pass", "polish this PR", "wrap up the PR", or otherwise asks for a final review-and-fix sweep before merge.

Alias for the Harn release workflow skill.

Use to convert a guess about codebase behavior into a recorded observation by running a probe snippet and persisting the outcome as a Fact.

Host-neutral lifecycle hook recipe for non-blocking context maintenance.

Linear webhook recipe for issue create/update events.

Poll recipe for Notion database or data source changes.

Slack webhook recipe for routing messages by keyword.

Slack Events API recipe for reaction_added workflows.

Slack webhook recipe with a local summarize predicate.

Use for Harn conformance tests, eval harnesses, deterministic fixtures, and language/runtime test coverage.

Cron trigger example that binds directly to an eval pack handler.

Use for authoring and running declarative structural rules — patterns, lint diagnostics, and codemods.

Overfit fixture that carries too much irrelevant context.
