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

asc-whats-new-writer 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 10d 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.

Origin

How it starts

The opening of the file, as written. The whole thing — 186 lines — stays where its author put it; the contents beside it link to each section on GitHub.

asc What's New Writer

Generate engaging, localized release notes from flexible input. Optionally pair with promotional text updates.

Preconditions

  • Metadata pulled locally into canonical files via asc metadata pull --app "APP_ID" --version "1.2.3" --dir "./metadata". OR: user provides keywords manually.
  • Auth configured for upload (asc auth login or ASC_* env vars).
  • The primary locale is en-US unless the user specifies otherwise.

Before You Start

  1. Read references/release_notes_guidelines.md for tone, structure, and examples.
  2. Identify the latest version directory under metadata/version/ (highest semver). Use this for all metadata reads.
  3. Enumerate existing locales by listing the JSON files in that version directory.

Phase 1: Gather Input

Accept one of three input modes (auto-detect):

Git Log

Parse commits since the last tag:

# Find latest tag
git describe --tags --abbrev=0

# List commits since that tag
git log $(git describe --tags --abbrev=0)..HEAD --oneline --no-merges

Filter out noise: merge commits, dependency bumps, CI changes, formatting-only commits. Extract user-facing changes.

Bullet Points

User provides rough bullets like:

  • "improved search"
  • "fixed crash on launch"
  • "added sleep timer"

Free Text

User describes changes conversationally:

"We made search faster, fixed that annoying crash when you open the app, and added a sleep timer feature"

The skill extracts and structures the changes from the text.

No Input Provided

Prompt the user: "What changed in this release? You can paste git log output, bullet points, or just describe the changes."

Phase 2: Draft Notes (Primary Locale)

Step 1: Classify Changes

Group changes into sections per the guidelines:

  • New — new features or capabilities
  • Improved — enhancements to existing features
  • Fixed — bug fixes users would notice

Omit empty sections. If all changes are fixes, only show "Fixed."

Step 2: Write Benefit-Focused Copy

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
