agentx

claudecodex

Get your agent's real runs into AgentX, then score them, then turn what they measure into a code fix. /instrument sets up a Python agent and proves it with traces it reads back; /run-eval evaluates it against a dataset it can also create - templates, files, or cases curated from live traces; /eval-fix triages the evaluation against the source and re-runs it on the same dataset.

dimagi/dimagi-claude-workflows 3

Build agent-step LangGraph agents — a ReAct agent fronted by one batching tool over a deterministic flow-controller runner (vendored and versioned; agent-step 3.0.1). Bootstrap a project (runner library + streaming CLI + graph/state/prompt scaffold + the required local sandbox service), then add domain tools declaratively: each action declares its params, prereqs and verdict ROWS — summary, doctrine, state write, effects, one authority per outcome — and its executor just names the verdict. The engine owns the machinery and the model-facing language it enforces: composed action descriptions, per-gate reply contracts, the spliceable turn-protocol prompt fragment, and engine-rendered read-backs and standing asks the model speaks verbatim. Mechanisms are configuration, not prompt prose — confirmation propose/execute gates with attempt budgets and stored-byte repetition, OTP and double-entry match gates, multi-turn flows, paginated reads, escalation ladders that count the prompt's "once" rules and escalate themselves, capture-bounce bounds, an engine-enforced abort policy, typed handoff routes, and a state-resolved handback envelope with orchestrator/specialized agent roles plus off-topic delegation. Graph state is one Zod schema (reducers + invoke-boundary validation, channel-completeness enforced at construction). Also: caller-capture param primitives, the twelve measured host-architecture design principles, porting an existing project onto agent-step, Kafka run-tracing observability via the companion kafka-observability plugin, the three-layer test methodology (runner unit / sandbox / prompt-input), and a channel-middleware contract audit.

crucible

claude

A mini-foundry — the build-verify-fix engine without the MCP server or the planning interview. You bring a structured spec (markdown with stable requirement IDs + acceptance criteria); crucible builds it and refuses to let it drift. /crucible:build <spec-file> decomposes the spec into units with DISJOINT file ownership, shows the split for one approval, then runs a Workflow engine: CAST (parallel deliberate-engineering builders, each handed its unit prompt verbatim, each emitting re-executable evidence bound to requirement IDs) → INSPECT (three blind orthogonal streams — wiring exists/substantive/wired, spec-before-code fresh-eyes assay, and re-execution of every evidence command) → GRIND (every non-passing verdict is a defect; fix the affected units and full-re-inspect, loop until zero or a cycle cap) → ASSAY (fresh-eyes agents read the spec first, form expectations, then confirm each requirement). Refuses a dirty tree; edits the shared working tree under disjoint ownership; commits per-unit only on user say-so so any unit is one revert away. Keeps foundry's load-bearing principles — verbatim unit prompts (no interpretation layer), multi-stream blind verification (build-green ≠ done), evidence binding, defect-to-zero grind, spec-before-code assay, an engine that routes and verifies but never re-narrates the spec or judges the code itself. Drops what needs the heavy machinery: no MCP gates/hashing, no isolated-worktree evidence, no brownfield flow-graph interview. forge plans → foundry builds; crucible is foundry's build engine, mini.
