forgeplan-brownfield-pack

Brownfield extraction pack — turns legacy code and documents into a structured forgeplan graph through a discover agent and twelve extraction skills (ubiquitous language, use cases, invariants, causal links, scenarios, knowledge-graph curation, reproducibility). Use when taking over an undocumented codebase and the first problem is not what to build but what is already there and why it is that way. Full history in CHANGELOG.md.

What it installs

Skills (12)

  • canonical-reproducer

    Produces self-contained standalone documents (DDL, pseudo-code, SDL) with zero `file:line` references in final sections. Triggers — \"extract canonical reproducer\", \"brownfield canonical reproducer\", \"/canonical-reproducer\".

  • causal-linker

    Maps actions, events, and side-effects into causal chains. Builds "X causes Y" relations across the codebase. Triggers — "extract causal linker", "brownfield causal linker", "/causal-linker".

  • hypothesis-triangulator

    Validates hypotheses against multiple independent sources to assign confidence scores. Triggers — \"extract hypothesis triangulator\", \"brownfield hypothesis triangulator\", \"/hypothesis-triangulator\".

  • intent-inferrer

    Given a code pattern, generates 3+ candidate hypotheses explaining **why** it's this way. Triggers — \"extract intent inferrer\", \"brownfield intent inferrer\", \"/intent-inferrer\".

  • interview-packager

    Clusters parked hypotheses and open questions into structured Domain Owner interview packets. Triggers — \"extract interview packager\", \"brownfield interview packager\", \"/interview-packager\".

  • invariant-detector

    Extracts business rules from code guards (`if/throw/assert`) and groups them semantically. Triggers — \"extract invariant detector\", \"brownfield invariant detector\", \"/invariant-detector\".

  • kg-curator

    Builds and maintains the knowledge graph connecting glossary terms, use-cases, invariants, scenarios, hypotheses, domain-models. Detects contradictions. Triggers — \"extract kg curator\", \"brownfield kg curator\", \"/kg-curator\".

  • rag-packager

    Packages verified canonical documentation for ingestion into a RAG (Retrieval-Augmented Generation) system. Produces chunks, metadata, and retrieval-friendly structure. Triggers — \"extract rag packager\", \"brownfield rag packager\", \"/rag-packager\".

  • reproducibility-validator

    Verifies that canonical documentation is actually sufficient to reproduce the described system. The "code deletion test" in automated form. Triggers — "extract reproducibility validator", "brownfield reproducibility validator", "/reproducibility-validator".

  • scenario-writer

    Converts verified use cases + invariants into Gherkin Given/When/Then scenarios with Mermaid sequence diagrams. Triggers — \"extract scenario writer\", \"brownfield scenario writer\", \"/scenario-writer\".

  • ubiquitous-language

    Extracts business terms, definitions, aliases, and synonyms from a codebase to build a domain glossary. Triggers — \"extract ubiquitous language\", \"brownfield ubiquitous language\", \"/ubiquitous-language\".

  • use-case-miner

    Maps entry points to user journeys — from trigger to business outcome. Triggers — \"extract use case miner\", \"brownfield use case miner\", \"/use-case-miner\".

Flagship workflow plugin of the ForgePlan ecosystem — the skills, templates and authoring contract the rest of the marketplace is written against: the smith methodology router (14 contexts), the agent-authoring guide every forgeplan-aware agent follows, and the gate, cleanup and insight skills that keep a pipeline honest. Use when you want the methodology itself rather than one specialist — deciding how to approach a task, gating an artifact before activation, or authoring a new agent to the house canon. Full history in CHANGELOG.md.

Professional specialist agents: security and prompt-injection review, PII detection, architecture and staff-level system review, the pre-activation guardian gate, ADR and specification authors, research analysts and infrastructure roles. Use when a task needs a named expert rather than a generalist — an OWASP/STRIDE pass, an architectural fitness review, a decision recorded as an ADR, or the last gate before an artifact is activated. Full history in CHANGELOG.md.

CANVAS design-system-to-code methodology: a coordinator walks a Pencil design through capture, audit, norm-check, vectorize and assemble, dispatching every phase and every verifier as a separate isolated context with a blocking generator-is-not-verifier gate at each handoff, plus a fail-closed hook that blocks source writes until the token contract is active. Use when a design system has to become working components in the project's own framework, with visual parity and token fidelity proven rather than asserted. Full history in CHANGELOG.md.

Builds a navigable map of a project — zones, nodes and verified edges — as a `map.json`, through an eight-agent pipeline (scan -> extract -> verify -> emit -> validate) where every stage runs in a fresh isolated context and a deterministic guardian script, not an LLM, is the sole authority on whether the result can be trusted. Use when you need a structural view of a large or unfamiliar repository that a file tree cannot give, or when a project's forgeplan artifact graph should be shown alongside its code. Not a documentation generator: an edge is either sourced from the artifact graph or proven by a grep, and an unproven one is dropped rather than shipped as noise. Full history in CHANGELOG.md.

fpl-hsmem

claude

Project-scoped cross-session memory for Hindsight API >=0.10.2 and <0.11.0. Use when a repository explicitly opts in via .hindsight.json; hooks default off, enrichment is operator-gated, and BankGate is client safety, not server authorization.

Core engineering agents: the source-mutating coder, the code reviewer and test runner that record evidence, plus debugger, planner, researcher, performance and production-readiness roles. Use when the work is ordinary engineering — implement this, review that diff, run the suite and report coverage against the acceptance criteria — and the reviewer should be a different context from the author. Full history in CHANGELOG.md.
