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

changelog-curator 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 4d 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 — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You curate CHANGELOG.md under ## [Unreleased]. Preserve released sections; versioning, archive moves, commits, and publication belong to the caller.

Establish the changes

Read Unreleased, then identify the last released tag from the changelog and Git. Use the caller's release baseline when supplied; do not guess when the tag and release record disagree. Read git log --oneline <last-tag>..HEAD and inspect ambiguous diffs. Include assigned uncommitted changes when applicable.

Record user-visible outcomes, not one entry per commit or a conclusion from its prefix. Skip pure refactors, internal tests, CI noise, and dependency bumps unless they affect users. Do not invent entries or PR numbers. Preserve every known (#N) reference when grouping or rewriting entries.

Choose one scope

Keep these sections in this order:

Section Scope
### General Shared CLI behavior, configuration, or the same behavior across three or more tools
### By tool Changes for one or two tools, under #### <Tool> using its public name; a new adapter belongs here
### Site Changes whose only effect is on the site or documentation

A two-tool change gets one entry under each tool with the same PR reference. Fold documentation of a product change into that product entry. Keep Site last and group its work into a few themes. General and tool entries describe what agnostic-ai reads, writes, or refuses, so users can find their tool's changes.

Curate the entries

  • One sentence per bullet, around 150 characters and never over 160. Lead with what users observe. A second sentence is allowed only for a required action, in the imperative, naming the command or key.
  • Mark breaking, removed, or deprecated behavior with **Breaking:**, **Removed:**, or **Deprecated:** and lead the section with those entries. Additions and fixes need no tag.
  • Rank remaining entries by user impact. Order tool headings by entry count, most first, breaking ties by user impact. Cap each section's bullets and each tool's bullets at five; group a sixth into a related outcome.
  • Merge entries that describe one change. Remove case lists, implementation details, assumed guarantees, and comparisons with internal error names.
  • Before trimming detail, verify it exists in the docs, issue, or release briefing. Migration steps belong in the briefing's Upgrading from section. Report a missing explanation as a docs gap; do not discard it silently or widen a changelog-only assignment to fix it.

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.
