Formal verification for real codebases: find concurrency, data-flow, state-management, and graph bugs with TLA+ and Lean 4, reproduce and fix them, simplify code with proofs, and publish results as Artifact reports.
Not in a marketplace yet, so it loads for one session with --plugin-dir.
Plugin proof-skills in opum-ai/proof-skills. Commands read from the repo's manifest — 1 month ago.
loreAuthor, retrieve, and maintain OKF documentation with the lore CLI, including explicit multi-repository workspaces. Use whenever reading, writing, linking, moving, querying, or checking docs, so Story/Task coupling, managed blocks, provenance, and cross-links stay coherent. Run `lore instructions` f
questDrive this repo's task tracker with the quest CLI instead of editing backlog/tracker state directly. Use whenever creating, listing, viewing, editing, completing, or archiving tasks, drafts, milestones, or decisions in a Quest-initialized workspace. Run `quest instructions --list` for the workflow g
formal-verifyEnd-to-end formal-methods bug hunting for real codebases in any language — scope a risky concern, model it in TLA+ and/or Lean 4, check it, turn every counterexample into a failing test, fix the code, re-verify, and publish the results as an Artifact report. Use this skill whenever the user wants to
lean-modelUse this skill to prove or refute properties of real software in Lean 4. The target is the user's own code, not textbook math. It covers state machines, concurrency and interleavings, async handlers, retries and idempotency, queues, batching pipelines, and graph algorithms such as topological order,
proof-simplifyUse verified TLA+ specs and Lean proofs to simplify real code safely — delete defensive checks the invariants make dead, remove locks/transactions/retries that do no work, collapse redundant states and flags, replace complex implementations with simpler ones proven equivalent, and encode invariants
tlaplus-modelTLA+/TLC model-checking skill. Use it whenever TLA+, PlusCal, Quint, Apalache, TLC, a .tla/.cfg file, or model-checker output appears. That includes a pasted TLC error, \"Invariant X is violated\", or a State 1/State 2… counterexample trace the user wants explained or triaged (real bug, model artifa
Twelve TACAS-specific skills for the ETAPS Tools and Algorithms for the Construction and Analysis of Systems conference, covering its four paper categories, per-category anonymity, mandatory artifact evaluation for tool papers, ETAPS Artifact Badges, LNCS gold-open-access proceedings, and SV-COMP, grounded in the TACAS 2026/2027 and ETAPS joint calls, Springer LNCS, and dblp.

Teach agents to write idiomatic, correct, current Ada and SPARK (Ada 2022) - contracts (aspects, Pre'Class), the Alire ecosystem, SPARK proof (AoRTE, assurance levels, ownership/borrow), embedded (Ravenscar/Jorvik), and GNAT/GNAT SAS tooling; blocks stale pre-2022 advice (GNAT Community, pragma contracts, CodePeer)
1 skill
Lean 4 language server with per-file Lake project-root detection (lake serve, or lean --server for standalone files), elan toolchain discovery, multi-project and worktree routing, and bounded memory (Lean workers are closed when idle or past a cap). Bundles the lean-goal CLI for proof goals, candidate tactics and Mathlib-wide lemma search.

Unified Lean 4 plugin (draft, formalize, autoformalize, prove, autoprove, disprove, checkpoint, review, refactor, golf, learn, diagnose) — LSP-first, scripts fallback
1 skill · 12 commands · 4 agents · hooks
Agent skills for working with Quint — the formal specification language for distributed systems. Covers spec writing, TLA+ translation, code-to-spec generation, spec review, and verification framing.
