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.

Security

Grade A, and why

patch-notes 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 1mo 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 — 121 lines — stays where its author put it; the contents beside it link to each section on GitHub.

When this skill is invoked:

  1. Parse the arguments:

    • version: the release version to generate notes for (e.g., 1.2.0)
    • --style: output style — brief (bullet points), detailed (with context), full (with developer commentary). Default: detailed.
  2. Gather change data from multiple sources:

    • Read the internal changelog at production/releases/[version]/changelog.md if it exists
    • Run git log between the previous release tag and current tag/HEAD
    • Read sprint retrospectives in production/sprints/ for context
    • Read any balance change documents in design/balance/
    • Read bug fix records from QA if available
  3. Categorize all changes into player-facing categories:

    • New Content: new features, maps, characters, items, modes
    • Gameplay Changes: balance adjustments, mechanic changes, progression changes
    • Quality of Life: UI improvements, convenience features, accessibility
    • Bug Fixes: grouped by system (combat, UI, networking, etc.)
    • Performance: optimization improvements players might notice
    • Known Issues: transparency about unresolved problems
  4. Translate developer language to player language:

    • "Refactored damage calculation pipeline" → "Improved hit detection accuracy"
    • "Fixed null reference in inventory manager" → "Fixed a crash when opening inventory"
    • "Reduced GC allocations in combat loop" → "Improved combat performance"
    • Remove purely internal changes that don't affect players
    • Preserve specific numbers for balance changes (damage: 50 → 45)
  5. Generate the patch notes using the appropriate style:

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.
