This plugin runs code on your machine — it starts local MCP servers. The exact commands are listed below; read them before installing.
filigree-workflowThis skill should be used when the user asks to "track work", "create an issue", "find something to work on", "what should I work on next", "triage bugs", "close an issue", "check what's blocked", "plan a milestone", "review sprint progress", "coordinate agents", or when working in a project that us
using-audit-pipelinesUse when a system makes procedural decisions that must be defensible after the fact — rule firings, governor decisions, state transitions, gate verdicts, eligibility determinations, automated approvals — and you need a verifiable provenance chain rather than ordinary observability. Use when an audit
using-contract-engineeringUse when designing, evolving, or reviewing **typed contracts between subsystems** — the records that cross authority boundaries in a pipeline, service mesh, or multi-stage system. Use when a consumer crashed on a missing field and the proposed fix is a default or a lenient reader; when a schema is c
using-determinism-and-replayUse when designing a system whose past behaviour must be recoverable as a fact — RL training substrates, multi-agent simulations, deterministic game engines, replay-debuggable services, multiplayer lockstep, or any pipeline where "I cannot reproduce that bug" is unacceptable. Use when teams disagree
using-devops-engineeringUse when building or fixing the path from commit to running production — CI/CD pipelines and verification gates, zero-downtime deployment, infrastructure as code, container build hygiene, Kubernetes/orchestration runtime, observability (metrics/logs/traces, SLI/SLO), incident response and on-call, r
using-distributed-systemsUse when designing a system that spans more than one process, machine, or failure domain and a partition, crash, or duplicate must not silently corrupt state. Use when you see split-brain, lost writes under partition, duplicate processing, stuck or half-applied sagas, retry storms, dual writes drift
using-embedded-databaseUse when running **SQLite or DuckDB inside an application process** as the durable store — not as a development convenience but as the production database. Use when scaling an SQLite layer that worked at low concurrency and is now hitting SQLITE_BUSY, WAL bloat, lock contention, schema-migration cer
using-software-engineeringUse when facing complex engineering challenges that require systematic methodology - horrible bugs, safe refactoring, code review, production incidents, technical debt decisions, or building confidence in unfamiliar codebases
using-experiment-formalisationUse when formalising an experiment as a machine-checkable record layer using scientific-experiment ontologies — EXPO (Soldatova & King's ontology of scientific experiments), SUMO or BFO as upper ontology, PROV-O for lineage. Use when handed a mapping of your system onto EXPO and asked to check or ex
using-mcp-engineeringUse when designing, implementing, or auditing an MCP (Model Context Protocol) server — tool API design, idempotency under agent retry, structured error envelopes agents can recover from, schema versioning across model drift, transport reliability (stdio / HTTP), output-shape and pagination disciplin

Use for both producer work (build the decompos
using-product-managementUse when a Claude is taking **standing ownership** of a software product across many sessions — discovery, strategy, specs, and value validation — deciding *what to build, why, for whom,* and *whether it worked*, with continuity, decision provenance, and an authority boundary that escalates irrevers
using-program-managementUse when **managing the delivery of work** rather than building it — running a project or a program, not writing its code. Use when a team is busy but outcomes are not landing, when "when will it be done" has no defensible answer, when status is green every week until it is suddenly red, when depend
using-pyo3-interopUse when building or maintaining a **PyO3 extension module** — a Rust crate exposed to Python as an importable extension. Use when scaling a PyO3 prototype that worked at low call rates and is now in a hot loop (RL self-play, batched inference, real-time pipeline). Use when the boundary symptom is G

Use when compiled output differs from eager, gradients mismat
