Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00033 | $0.01933 |
| Opus 5 | $0.00016 | $0.00966 |
| Sonnet 5 | $0.00007 | $0.00387 |
| Haiku 4.5 | $0.00003 | $0.00193 |
Grade A, and why
achievements 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 2d 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 — 238 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Achievement System
Steam-style gamification for the development workflow. Earn XP by coding, fixing bugs, shipping features, and collaborating with agents. Level up, maintain streaks, and unlock achievements across 5 skill trees.
XP Level Thresholds
| Level | XP Required | Title |
|---|---|---|
| 1 | 0 | Apprentice |
| 2 | 100 | Developer |
| 3 | 300 | Engineer |
| 5 | 500 | Senior Engineer |
| 10 | 1000 | Staff Engineer |
| 20 | 3000 | Principal Engineer |
| 50 | 10000 | Legendary |
Streak System
Consecutive days of coding activity multiply XP earned:
| Streak | Multiplier |
|---|---|
| 1-2 days | 1.0x |
| 3-6 days | 1.25x |
| 7-13 days | 1.5x |
| 14-29 days | 2.0x |
| 30+ days | 3.0x |
Missing a day resets the streak to 0.

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.
- 2d ago First seen · 238 lines · 33 tokens per session scan A 98996787adb4
achievements is a skill published in the GitHub repository vibeeval/vibecosystem (530 stars, last pushed 28d ago), licensed MIT. It adds 33 tokens to every session and 1,933 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.

Phase 6 — skeptical QA. Run the game, watch it, then judge against the contract. Default = functional check; --strict adds quality and edge-case passes.
flame-harness-design
Phase 3 — define the Flutter designtokens.dart spec (palette, typography, spacing), the game's art/visual concept, and the asset/audio sourcing plan.
flame-harness-retro
Phase 11 — score the completed pipeline against Anthropic's 9 harness principles plus game quality, and write the retrospective.
flame-harness-build
Phase 8 — bootstrap signing credentials, generate fastlane config from templates, and build + upload signed IPA (TestFlight) and AAB (internal track).
