About this skill

gpc-games

Manage Google Play Games Services achievement and leaderboard configurations with GPC, through the Games Configuration API (gamesconfiguration v1configuration).

When to use

Use this skill when defining or syncing the achievements and leaderboards for a game: creating, updating, deleting, listing, or diffing their configuration. This is publisher-side configuration (the catalog of achievements/leaderboards), not the player-facing runtime that unlocks them in a session.

Do NOT use this skill for app releases, tracks, or AAB uploads (see gpc-release-flow), or for in-app purchases and subscriptions (see gpc-monetization).

Inputs required

  • An authenticated GPC setup (gpc-setup). The same service account / OAuth used for publishing works here.
  • A numeric game application ID (the Play Games "Application ID", distinct from the Android package name). Resolve it once and reuse it (see Procedure step 1).
  • For create/update: a JSON config file. See references/games-config-schema.md for the achievement and leaderboard shapes.

Procedure

0. Verify setup

gpc doctor

Confirm auth is configured before any games command. All write operations support --dry-run.

1. Resolve and set the game ID

gpc games needs the numeric game application ID. Provide it one of three ways (highest precedence first):

# Per-command flag
gpc games achievements list --game-id 1234567890

# Environment variable (CI-friendly)
export GPC_GAME_ID=1234567890

# Config file: set games.applicationId in .gpcrc.json
gpc config set games.applicationId 1234567890

The numeric ID is shown in the Play Console under Play Games Services > Configuration. It is NOT the com.example.mygame package name.

2. Achievements

# List (supports --limit / --next-page; --json returns the standard envelope)
gpc games achievements list
gpc games achievements list --limit 10 --json

# Get one by its achievement ID
gpc games achievements get CgkI1234567890

# Create from a JSON file (preview first)
gpc games achievements create --file achievement.json --dry-run
gpc games achievements create --file achievement.json

# Update an existing achievement
gpc games achievements update CgkI1234567890 --file achievement.json

# Delete (prompts for confirmation; --yes to skip)
gpc games achievements delete CgkI1234567890 --yes

Achievement config is STANDARD or INCREMENTAL. Incremental achievements add stepsToUnlock. initialState is HIDDEN or REVEALED. See references/games-config-schema.md.

3. Leaderboards

# List / get
gpc games leaderboards list --json
gpc games leaderboards get CgkI9876543210

# Create / update from a JSON file
gpc games leaderboards create --file leaderboard.json --dry-run
gpc games leaderboards create --file leaderboard.json
gpc games leaderboards update CgkI9876543210 --file leaderboard.json

# Delete (prompts for confirmation)
gpc games leaderboards delete CgkI9876543210

Leaderboard config sets scoreOrder (LARGER_IS_BETTER / SMALLER_IS_BETTER) and a scoreFormat.numberFormatType (NUMERIC, TIME_DURATION, or CURRENCY).

4. Diff and sync workflow

diff compares a local JSON file against the remote configuration field-by-field, so you can review drift before pushing it. Use it as the dry-run for a sync:

gpc games achievements diff CgkI1234567890 --file achievement.json
gpc games leaderboards diff CgkI9876543210 --file leaderboard.json

Pattern: keep each achievement/leaderboard as a versioned JSON file in the repo, diff in CI to detect config drift, then update --file to apply.

push and pull bulk-sync a whole directory (v0.9.90+):

gpc games achievements push ./game-config/achievements   # creates files without an id, updates those with one
gpc games achievements pull ./game-config/achievements   # writes every config to <id>.json
gpc games leaderboards push ./game-config/leaderboards
gpc games leaderboards pull ./game-config/leaderboards

set-icon uploads a 512x512 PNG or JPG for a single achievement or leaderboard (content type inferred from the extension, honors --dry-run):

gpc games achievements set-icon CgkI1234567890 ./icons/first-win.png
gpc games leaderboards set-icon CgkI9876543210 ./icons/high-scores.png

set-icon depends on an endpoint Google has retired. Icon upload uses the Games Configuration API's imageConfigurations resource, which Google removed from its published API (discovery revision 20260820). If the route has been switched off the command fails with API_ENDPOINT_RETIRED -- as of v0.9.96 that is reported with Google's own message and a pointer to the Play Console, instead of a bare 404. Set the icon in Play Console in that case. Every other games command, push and pull included, is unaffected.

5. Runtime (read-only)

The runtime commands read the player-facing definitions for a published game. They are read-only and keyed by the app package, not the game ID:

gpc games runtime leaderboards --app com.example.mygame
gpc games runtime achievements --app com.example.mygame

Verification

  • gpc games achievements list --json / leaderboards list --json return the standard list envelope: { <key>, nextPageToken, meta.count, message? }.
  • After a create/update, re-run diff with the same file: a clean diff confirms the remote matches local.
  • Use --dry-run on every create/update to preview the request without writing.

Failure modes / debugging

  • "No game ID" / missing application ID: set --game-id, GPC_GAME_ID, or games.applicationId (step 1). Remember it is the numeric Play Games ID, not the package name.
  • gpc games events no longer exists (removed in v0.9.86) — events are configured in the Play Console UI only.
  • Runtime commands moved under gpc games runtime in v0.9.86; the old top-level runtime list commands are gone.
  • API_ENDPOINT_RETIRED on set-icon: Google removed the imageConfigurations icon-upload route from its published API. Not a fixable configuration problem -- upload the icon in Play Console. push/pull and every other games command still work.
  • Permission errors: the service account needs access to the game in Play Games Services; see gpc-troubleshooting for the error catalog.
