Estimate user stories tracked in Notion or Linear using Fibonacci story points at two confidence levels (50% and 90%), following Amalgama's standardized methodology. Provides skills for single-story and bulk estimation backed by subagents for similar-story lookup, codebase investigation, and third-party integration research.
Cada skill se invoca con su slash command o cuando la descripción calza con lo que pedís.
Estima una historia de Notion o Linear con la metodología de Amalgama, buscando historias similares ya estimadas y señales en el código antes de dar un número.
Estima un sprint, un backlog o una vista entera, corriendo el mismo método historia por historia en paralelo.

Assesses whether a user story can leverage existing codebase patterns or requires net-new infrastructure. Searches the codebase with Glob and Grep for the story's key concepts. Invoked by the estimate and estimate-bulk skills only when a codebase is available. Returns a short report per concept (exists / partial / net-new) plus an overall verdict. Does not propose an estimate.
Researches a third-party integration's complexity — vendor type, integration mode (native SDK, WebView embed, REST API, OAuth, webhook), documentation quality, and known platform-specific gotchas. Invoked by the estimate and estimate-bulk skills when a story mentions a vendor/provider/SDK/integration signal. Uses WebSearch and WebFetch to consult vendor docs directly rather than relying on catch-all heuristics. Does…
Finds semantically similar already-estimated user stories to calibrate a new estimate. Searches the current project's backlog via Notion or Linear MCP, plus the plugin's curated anchors file. Invoked by the estimate and estimate-bulk skills. Returns a list of sized matches with URLs, estimate values, and a short reason each match is similar.
Produces Fibonacci story point estimates (50% and 90% confidence) for a single user story using Amalgama's methodology. Invoked by the estimate and estimate-bulk skills. Receives the story content, similar-story signals, codebase signals, and paths to the methodology and anchors references. Returns strict structured output the caller can parse.
