v8.0.4

Changed

• calculate teaches the spread rules instead of bouncing the model off
  them. The CP economy (8 EVs = 1 CP, each stat 0-32, 66 CP total) and a
  worked example (252 HP / 252 Atk / 4 SpD = 32 / 32 / 1 CP) now appear in the
  calculate description, the calculate_stats and check_speed descriptions,
  and the shared evs/championsPoints field descriptions. Validation errors
  are now self-correcting: the "both scales" error names each scale and the
  conversion, the range error repeats the value sent ("you sent 40"), and the
  cap error shows the breakdown and a concrete fix ("you sent 32 hp + 32 atk +
  32 spa = 96; drop to 66 or less, e.g. 32/32/1 = 65"). Also fixed the mangled
  "Pok00e9mon" lead-in in the compound tool descriptions. The principle: a
  validator that rejects without teaching is a token multiplier — ranges, caps,
  conversions and exclusivity belong in the description (and ideally the schema)
  before the validator enforces them.

v8.0.3

Changed

• The App hands off to the user, and degrades gracefully when a host drops
  structured content. The initialize instructions and the three App-linked
  workflow prompts (/team-doctor, /matchup-prep, /build-around) now tell
  the model to end its turn after an App tool call and let the user explore the
  board instead of summarizing and moving on. The View also rebuilds its
  envelope from the compact JSON text plus the host's reported tool context when
  a host delivers no structuredContent, so it renders and stays interactive on
  hosts that have not implemented complete structured result delivery.

v8.0.2

Fixed

• The six compound tools published an empty input schema. Their z.union
  of per-mode objects serialized to {"type":"object","properties":{}} — the
  SDK only converts object schemas and raw shapes to JSON Schema, and a union
  is neither — so an Apps host had no fields to render a form. The compound
  layer now registers a flat shape: the mode enum plus every field each mode
  accepts, unioned where a name is shared across modes (e.g. species is a
  string in lookup/species and an array in lookup/sprites), with the
  per-mode object re-enforcing the real required-field contract inside the
  handler. The smoke suite pins that every compound tool publishes its mode
  enum and fields.

v8.0.1

Fixed

• optimize_team pair recommendations split the first reason into single
  characters. The two-slot path spread a string (...condition ? … : …) where
  it meant to place one reason element, so reasons[0] became one character per
  entry and the output rendered a letter per line. The stray spread is removed;
  the smoke suite now asserts every reason is a multi-character string so the
  regression cannot return.

v8.0.0

Added

• The MCP App workspace. The server now exposes one portable MCP App —
  a single bundled HTML resource registered at ui://getcompetitive/workspace
  (text/html;profile=mcp-app) and linked from the three App tools. It renders
  three Views over the existing deterministic engine: Team Doctor
  (analyze_team synergy/diagnose — six sets, labelled heuristic score,
  stacked weaknesses, coverage, speed and top fixes), Team Builder
  (optimize_team — select a proposed member, validate with team_io
  legality, export the paste), and Matchup Board (prepare_matchup —
  bring four, speed races, calculated damage and heuristic leads, with the
  opponent's set assumptions shown beside each roll). The bundle is built by
  scripts/build-app.mjs with esbuild and embedded in the compiled server JS,
  so the stdio, HTTP and serverless Worker entrypoints serve byte-identical
  markup with no runtime filesystem read, no external CDN, fonts or scripts.
• A pinned App SDK. @modelcontextprotocol/ext-apps@1.7.5 (the release
  line that pairs with this server's @modelcontextprotocol/sdk@^1.30.0) is
  used for resource registration and App-side messages; the App itself imports
  the SDK's app-with-deps bundle. Host support is negotiated through the
  extension capability where the SDK requires it, and ordinary text output is
  preserved unchanged for hosts without Apps support.

Changed

• Breaking: the three App tools wrap structuredContent in a versioned
  envelope. analyze_team, optimize_team and prepare_matchup now return
  { schemaVersion: 1, view, tool, mode, regulation, data } in
  structuredContent, where data is the unchanged analytics payload at the
  requested detail level. The model-facing text (the compact JSON summary) is
  byte-for-byte the same; only structuredContent consumers migrate their
  reads to …structuredContent.data.<field>. schemaVersion is the migration
  hook: a View that does not recognise the number renders an unsupported-schema
  state instead of guessing. Every other tool's structuredContent is
  untouched, and no tool's analytics field was renamed or reshaped.
• The evidence app and the App are now distinct surfaces. The HTTP
  entrypoint's / page (the model-converses browser page) is unchanged; the
  MCP App is the sandboxed iframe served through resources/read.

Not included

• App-only tools (_meta.ui.visibility: ["app"]) are deferred: every View
  interaction uses the existing public tools, so the model catalog stays at
  nine tools and app-initiated drilldowns request detail: "evidence" without
  adding to the model's history. Private endpoints (e.g. ui_get_team_detail)
  will only be added if a focused drilldown needs one.

v6.3.1

Fixed

• Kingambit was reported illegal in Regulation Set M-C. The Bulbapedia
  page the rosters were scraped from omits Kingambit from its M-C eligible
  list (it appears in no revision of the page), so check_legality and
  team_io rejected a species with 29% measured M-C usage. The roster is
  restored from the official Pokémon Champions event pages (231 species;
  M-C adds 23 over M-B, not 29 as the notes claimed).

Changed

• Regulation rosters are now cumulative. The M series builds each set on
  the previous one, and the data reflects that: regulations.data.ts stores
  M-A in full (base) plus each later set's additions, and the full
  per-set lists are derived at load. Eligible species come straight from the
  official event pages — the Bulbapedia dependency that caused the Kingambit
  omission is gone — and extract-regs.mjs now fails without writing on any
  drop or source disagreement. Ingesting M-D is three steps: add the set to
  the script and to METADATA, run the script, run npm test. The golden
  tests pin the official roster sizes, Kingambit's M-C membership, and the
  no-drops invariant.

v6.3.0

Added

• The server now introduces itself. initialize returns a titled, described
  serverInfo (name, title, description, websiteUrl) plus instructions that
  tell the client's model the server is exclusively about Pokémon Champions —
  doubles, level 50, Mega Evolution, 66 stat points, Regulation Sets M-A–M-C —
  and how the eight mode-dispatching tools and six prompts hang together.
  Every tool description now names the game too, so a client that only
  surfaces the tool list still knows what it is connected to, and the npm
  description says so for directory listings.

v6.2.2

Changed

• The release guard has its first recorded catch. 6.2.1 tagged before its
  changelog heading was promoted, and the new workflow step refused to create
  a GitHub release for it (npm had already published); the heading was
  promoted and the release created with the same command the workflow runs.
  This release exercises the full loop end to end.

v6.2.1

Changed

• The release workflow mirrors npm to GitHub. Every tag now publishes the
  npm package and creates the GitHub Release with the matching CHANGELOG
  section as its body — the two "latest" pointers can no longer drift apart,
  and a version without a changelog section fails the run instead of shipping
  an unlabeled release.
