0.5.2: Rolling Data Assets & Lean Distribution

Pokémon Champions Skills 0.5.2

This release moves the heavyweight deliverables onto a rolling release so the repository stays lean, refreshes the M-4 environment, and expands the real-team evidence library.

Rolling data assets (new)

• The trilingual environment workbooks and rank-trend charts now ship as fixed-name assets on the rolling data-latest release: workbook_{zh,ja,en}.xlsx and trend_{single,double}_{zh,ja,en}.png.
• The README's download links (and embedded trend charts) always point at the newest snapshot; assets are replaced on every release, keeping exactly one current set.
• The git tree no longer carries binary deliverables, so cloning and updating the skills is significantly lighter.

Refreshed environment and real-team evidence

• Refreshed the M-4 / M-B Singles and Doubles rankings, detail panels, factual change reports, opponent caches, and trilingual workbooks (snapshot July 13, 2026).
• Expanded the real-team library: M-A regulation backfill including grand-prix teams, plus M-3 top ladder builds.

Data format improvements

• Shipped meta and cache files are now written in a stable row order (usage rank preserved as a per-row field), so anyone tracking the repository sees compact, meaningful diffs between refreshes instead of near-full-file rewrites.
• A detail row's detail_updated timestamp now appears only when the source provides a real per-Pokémon update time (see references/schema.md).

Data snapshot

• Season: M-4
• Regulation: M-B
• Snapshot updated: July 13, 2026

Latest environment deliverables (rolling)

Environment workbooks (xlsx) and rank-trend charts (png) for M-4 / M-B (snapshot 2026-07-13).

Fixed asset names; replaced on every release — only the newest snapshot is kept. See the README's Environment Workbooks section for direct links.

0.5.1: QuickJS Runtime & Data Refresh

Pokémon Champions Skills v0.5.1

This patch release makes the exact damage and Speed calculator substantially easier to install, refreshes the current M-4 environment evidence, and tightens the public installation workflow.

Node-free calculator runtime

• The vendored NCP JavaScript engine now runs in-process through quickjs-ng>=0.15 behind the public Python CLIs.
• The formulas and source data remain the same vendored NCP implementation; the host runtime does not reimplement the calculator.
• If quickjs-ng is unavailable, the same Python entries automatically delegate to the Node.js CLIs.
• QuickJS and Node calculation/query results use stable UTF-8/LF output and are covered by byte-parity, schema, error, and resident-worker tests.
• The calculator skill now ships its own requirements.txt.

Refreshed environment and real-team evidence

• Refreshed the M-4 / M-B Singles and Doubles rankings, detail panels, factual change reports, opponent caches, and trilingual workbooks from the current PokeChamp DB snapshot.
• Deepened the Limitless tournament crawl so completed-season Doubles updates cover the full regulation window instead of only the most recent tournament page.
• Refreshed the M-3 and M-4 real-team libraries while preserving their season, regulation, and format boundaries.

Clearer installation and documentation

• Agent-assisted installation is now the recommended default in the English, Simplified Chinese, and Japanese guides.
• The beginner workflow asks the agent to install all four skills, copy the bundled project instructions, install quickjs-ng (or verify Node fallback), and run a calculator schema check.
• The three guides now share the same examples, installation structure, dependency explanation, and acknowledgments.

Data snapshot

• Season: M-4
• Regulation: M-B
• Snapshot updated: July 11, 2026

Install or update

Recommended: ask an agent with shell access to install all four skills from this repository and install quickjs-ng>=0.15.

The npx skills route remains available:

npx skills add pmwl0128/pokemon_champion_agent
npx skills update

Claude Code users can also update through the bundled plugin marketplace metadata.

0.5.0: The Team-Building Release

I’m excited to publish Pokémon Champions Skills v0.5.0. This is the release where the project becomes the complete four-skill toolkit I originally wanted to use: battle-dex facts, current metagame data, exact damage and Speed calculations, and a fully shipped team-building workflow.

What’s New

The team skill is now part of the release

pokemon-champions-team can build, validate, diagnose, revise, and tune both Singles and Doubles teams. It accepts natural-language constraints, Showdown text, JSON, local roster files, and existing team notes, then coordinates the three factual skills where exact evidence is needed.

The workflow covers:

• deterministic legality checks with valid, invalid, and unknown outcomes;
• defensive, offensive, Speed, and functional team diagnosis;
• full top-metagame matchup review in both damage directions;
• Singles 6-pick-3 and Doubles 6-pick-4 selection analysis;
• SP cliff tuning for survival, Speed, OHKO, and 2HKO targets;
• candidate replacement comparisons and real-team structural evidence;
• final answer checks that keep assumptions, confidence, and calculations visible.

Real-team evidence without a hidden strength score

The package now ships a scrubbed real-team sample library, partitioned by season, regulation, and format. It is used to show which members and sets actually co-occur—not to create a leaderboard or silently hand back a copied team.

Metagame usage, observed team structures, event results, and exact calculations remain separate evidence views. The tools never collapse them into an opaque “best team” score.

Completely rewritten documentation

The release now has dedicated, full-length guides in English, Simplified Chinese, and Japanese. Each guide covers all four skills, installation options, a beginner project workflow, model-routing caveats, supported data scope, workbooks, data freshness, and source attribution.

The Japanese guide uses native competitive Pokémon terminology and professional technical phrasing rather than mechanically translated wording.

An Honest Note About Team-Building Quality

The team skill raises the floor of an AI answer: it reduces stale-memory mistakes, illegal sets, bad arithmetic, marginal-statistics stitching, forgotten constraints, and unsupported claims. It does not replace strong human team-building experience.

The best results still come from telling the agent how you want to win, which leads or selections you expect to use, what you frequently face, which weaknesses you are willing to accept, and what went wrong in actual games. Treat the first result as a grounded draft, then iterate with battle notes and replay observations.

Data Snapshot

• Season: M-4
• Regulation: M-B
• Snapshot date: July 10, 2026
• Formats: Singles and Doubles
• Included workbooks: English, Simplified Chinese, and Japanese facts-only environment reports

The supported data domain is Pokémon Champions. Main-series data from Sword and Shield, Scarlet and Violet, or other games is not used as a substitute when Champions values differ.

Thank you to everyone maintaining the calculators, reference sites, metagame feeds, tournament resources, and public team collections that make this project possible. I hope v0.5.0 makes Pokémon Champions analysis more reliable, more transparent, and much easier to iterate on.
