What is specter-progression?

An integration guide for Specter, a progression system for game tasks, missions, achievements, quests, streaks, battle passes, rewards, and levels.

Use it to send custom gameplay events, check player task progress, mark tasks complete through Specter’s rules, and support reward or level displays.

It explains how gameplay events trigger configured rules and how the game reads task status and handles rewards.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00105	$0.01536
Opus 5	$0.00053	$0.00768
Sonnet 5	$0.00021	$0.00307
Haiku 4.5	$0.00011	$0.00154

Security

Grade A, and why

specter-progression scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 115 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Specter Progression — tasks, achievements, battle pass, levels

Base URL and headers: see the specter skill. Tasks, rules and rewards are configured in the dashboard; the game's job is to (1) send events, (2) read status, (3) claim rewards.

The core loop: events drive everything

game does something
  → POST /events/send-custom  (Bearer)  with event name + parameters
  → Specter queues the event and evaluates task rules asynchronously (rules engine)
  → matching tasks are marked completed; rewards granted per claim mode
  → game polls /tasks/get-status (or player/me/get-task-status) and updates UI

POST /events/send-custom
{ "eventId": "match_finished", "customParams": { "score": 1500, "kills": 7, "won": true } }

eventId is the event's dashboard-configured id (slug), e.g. daily_streak_hit. It is NOT the event.id UUID that get-tasks returns inside task objects — sending that UUID fails with EventNotFoundException (1119). Verified against staging. Put gameplay values in customParams — task rule facts are matched against custom params. specterParams is for platform-default parameters; don't put your own fields there.

Validation is asynchronous (queue + rules engine) — completion lands seconds later, not in the response. Poll status when the player opens the quest screen; don't block gameplay on it.

Task model (what you configure, what the engine does)

A task = trigger event + optional parameters (aggregations over the player's event history)

business logic (conditions). See references/task-rules.md for the full rule semantics. Task kinds:

Kind	Behavior
One-time	Completes once per schedule cycle
Recurring	Resets each cycle (daily/weekly quests)
Cumulative (with parameters)	"Collect 1000 coins" — sums/aggregates event params over time
Streak / time-series	Last N events must all satisfy the condition
Step series	Staged progression through ordered steps
Task group / mission	Ordered set of tasks; group rewards on full completion

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
