Specter Skills tools (25, 14 write)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • specter_admin_call

    Escape hatch for the dashboard/admin API: POST to any /v1 admin endpoint that lacks a dedicated tool (e.g. match/add, member/invite/send, reward-set/create, games/add, tag/create, ugc-leaderboard/create, app-event/custom/subscribe-all, bulk-upload/*). Find the exact path + request body in the specter-admin references (references/endpoints-index.md and admin-endpoints.md). projectId is auto-injecte

  • specter_claim_reward

    Claim the test player's pending reward(s) from a source — this is how a game claims an ON-CLAIM task/mission reward after it completes (grant-reward-by-source). It grants the reward to the wallet/inventory and flips its status pending → completed. Identify the source by its slug/id and type.

  • specter_client_call

    Escape hatch for the game-facing API: POST to any /v2/client/* endpoint as the sandbox test player. Use for client calls that lack a dedicated tool (e.g. player/me/get-inventory, friends/send-request, stores/default-purchase, leaderboards/get-rankings, competitions/enter). Find the exact path + body in the client-api-index / curated-client-api references. asPlayer=true (default) sends the test-pla

  • specter_create_currencywrite action

    Create a virtual or real-money currency. `type` is "virtual" (in-game, e.g. coins/gems) or "real" (real-money). currencyId (slug) is auto-derived from the name if omitted. MUTATES live game config — confirm with the user and prefer staging.

  • specter_create_currency_conversionwrite action

    Define an exchange rate from one currency to another (e.g. 100 gems → 1 gold). Pass currencies by slug/name; the tool resolves them to the integer ids the API needs. MUTATES live game config — confirm and prefer staging.

  • specter_create_currency_policywrite action

    Attach a policy to a currency: "balance_limits" (min/max a player can hold), "currency_decay" (lose a % over time), or "earning_caps" (max earnable per period). Pass the currency by slug/name. MUTATES live game config — confirm and prefer staging.

  • specter_create_eventwrite action

    Create a custom event that tasks/achievements can be triggered by (e.g. "boss_defeated"). Create the event BEFORE the task that references it. eventId (slug) is auto-derived from the name. MUTATES live game config — confirm with the user and prefer staging.

  • specter_create_matchwrite action

    Create a multiplayer match template (the config a real-time session is based on). `format` is single/multi/team; `outcome` is how a winner is decided (highest score, fastest time, finish position). The game is resolved by name/slug. Matchmaking rules (team size, MMR) go in `fields`. MUTATES live game config — confirm and prefer staging.

  • specter_create_missionwrite action

    Create a MISSION: a pool of tasks where players see/complete a subset per cycle (typeId 1). Use for "daily missions", "rotating challenges", "pick N of these". For sequential use specter_create_step_series; for streaks use specter_create_time_series. Each task in `tasks` is created inline. MUTATES live game config — confirm and prefer staging.

  • specter_create_step_serieswrite action

    Create a STEP SERIES: ordered tasks where each unlocks the next (typeId 2). Use for "quest lines", "tutorial chains", "finish step 1 before step 2". The order of `tasks` (or each task's sortingOrder) defines the sequence. MUTATES live game config — confirm and prefer staging.

  • specter_create_taskwrite action

    Create a SINGLE-objective achievement (a "task"/"quest"/"objective" — one trigger, one reward). For multi-objective achievements use specter_create_mission (a pool), specter_create_step_series (sequential), or specter_create_time_series (streaks). `event` is the trigger event (slug/name, resolved automatically). `rewards` grants currencies/items/markers (by slug/name). `recurring` captures cadence

  • specter_create_time_serieswrite action

    Create a TIME SERIES: per-window recurring tasks, e.g. a daily login streak (typeId 3). Use for "streaks", "login N days in a row", "weekly recurring that resets on miss". `stageLength` is the window count (e.g. 7) and `interval` its unit (e.g. "day"). MUTATES live game config — confirm and prefer staging.

  • specter_delete_achievementwrite action

    Soft-delete a single task (kind="task") or a group (kind="mission"|"step_series"|"time_series"). Provide refs (slugs/names/ids). DESTRUCTIVE — confirm with the user first, and prefer staging.

  • specter_edit_currencywrite action

    Update an existing currency (name, description, code, type, …). Identify it by slug/name. MUTATES live game config — confirm and prefer staging.

  • specter_edit_taskwrite action

    Update an existing single task's name, description, rewardClaim, recurrence, or businessLogic (identify it by slug/name). To CHANGE REWARDS, delete and recreate the task — task/edit uses diff-semantics on rewards that aren't reliably expressible here. MUTATES live game config — confirm and prefer staging.

  • specter_generate_client_code

    Generate ready-to-paste game integration code (v2 client REST) wired with this project's real client api-key + a real event slug. Covers login, firing events, reading tasks, and wallet. JS works anywhere; C# is dependency-free Unity (the official Specter Unity SDK is recommended for production).

  • specter_get_player_state

    Sign in the sandbox test player and read their task/achievement status, wallet balances, and inventory. Use to inspect what a player currently sees, or to check an achievement's progress.

  • specter_get_reward_history

    Read the test player's reward history — including PENDING rewards waiting to be claimed (on-claim tasks). Filter by status ('pending' shows claimable). Each entry has sourceType + sourceId (e.g. the task), amount, and status (pending → completed).

  • specter_login

    Opens the Specter dashboard in the browser so the member can sign in (email/password, Google, or Apple) and authorize this tool. Required once before creating currencies/tasks. No password is ever shared with the tool.

  • specter_schedule_achievement

    Activate a created task or task-group (mission/step-series/time-series) by setting its dates/recurrence. Pass exactly one of taskRef (single task) or groupRef (a group), by slug/name/id. Omitting startDate makes it go live immediately. MUTATES live game config — confirm and prefer staging.

  • specter_send_eventwrite action

    Send a custom event (by its slug) as the sandbox test player — the same event your game would fire. Use to trigger tasks/achievements and verify they respond. `params` are the event parameters (statistics/states) your rule references.

  • specter_stop_achievement

    Halt a live task or task-group (keeps the record; reversible by scheduling again). Pass exactly one of taskRef / groupRef. MUTATES live game config — confirm and prefer staging.

  • specter_test_achievement

    Prove a configured task/achievement works: reads the test player's task status, fires the trigger event (with optional params), polls again, and reports whether the task progressed/completed. Use right after creating a task to verify it actually fires.

  • specter_update_entitywrite action

    Generic editor for the long tail: update an item/bundle/store/leaderboard/competition/battlepass/level_system/marker/mission/step_series/time_series/event. Pass the entity's `id` (from the matching list_* tool) and the `fields` to change. MUTATES live game config — confirm and prefer staging.

  • specter_verify_setup

    Smoke-test the configured Specter project: api-key validity, project info, currencies, test-player login, wallet provisioning, and tasks. Use this first to answer "is my Specter backend set up correctly?".

What the publisher says

From the Specter Skills repository's README, as published. We do not edit it. Read it on GitHub

specter-skills

Build your game backend by talking to Claude.

specter-skills teaches Claude everything about Specter — the game backend platform — so you can add player accounts, an in-game economy, daily quests, leaderboards, tournaments, battle passes, and real-time multiplayer to your game in plain English, and get correct, working code plus the ability to configure your backend without ever opening the dashboard.

No SDK to learn. No API docs to read. Install it, then ask.

You:    "Add Specter to my game — silent login, a coins wallet, and a daily
         quest 'play 3 matches' that rewards 100 coins."
Claude: ...writes the integration code, sets up the quest in your backend, done.

What's inside

This one package ships two halves of the same product:

Skills work in Claude Code, Claude Desktop, the Claude Agent SDK, and any other skills-aware host. The MCP server works in any MCP-compatible host (Claude Desktop, Claude Code, …).

Quickstart

1. Install the skills in your game project:

npx specter-skills init

2. Get your API key from console.specterapp.xyz (Project → API Keys).

3. Ask Claude to build something:

"Add Specter email login and a gem currency to my Unity game."

The right skill activates automatically and Claude writes the integration. That's it.

💡 Want Claude to also set up the backend for you (create currencies, quests, leaderboards)?

Add the MCP server and ask *"create a gems currency and a daily login quest in

my Specter project."*
