changelog

A release-note workflow that creates or updates a CHANGELOG.md file, which records what changed in each software version. It gathers merged changes, checks contributors, and writes an entry for a specified release.

In plain words
What is it for?
Use it to prepare changelog entries for a version, list relevant changes, and credit outside contributors.
Why use it?
It saves you from manually collecting pull requests, commits, release history, and contributor information.

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.

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 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 3d 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 — 89 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Changelog Generation

Generate a changelog entry for a new release by analyzing merged PRs since the last tag.

Parameters

The user provides:

  • Version number -- e.g., 0.5.3
  • Additional PRs -- optionally, PRs not yet merged that should be included

Step 1: Gather Data

  1. Find the previous release tag: git tag --sort=-version:refname | head -1
  2. List all merge commits since that tag: git log <tag>..HEAD --merges --format='%s' | grep -v "Merge branch"
  3. Get PR details with: gh pr list --state merged --base main --search "merged:><tag-date>" --json number,title,author --limit 50
  4. List contributors: git log <tag>..HEAD --format='%an' --no-merges | sort | uniq -c | sort -rn

Step 2: Identify External Contributors

To determine if a contributor is external, check for an @entire.io email:

git log --all --format='%an <%ae>' --author="<name>" | sort -u

If they have an @entire.io email anywhere in git history, they are internal. Only list external contributors in the Thanks section.

Also check the memory file at memory/project_team_members.md for known internal/external mappings.

Step 3: Write the Entry

Insert the new version section at the top of CHANGELOG.md, after the header and before the previous version.

Format

Follow the existing style in CHANGELOG.md exactly:

## [X.Y.Z] - YYYY-MM-DD

### Added

- Feature description with context ([#123](https://github.com/entireio/cli/pull/123))

### Changed

- Change description ([#456](https://github.com/entireio/cli/pull/456))

### Fixed

- Bug fix description ([#789](https://github.com/entireio/cli/pull/789))

### Housekeeping

- Maintenance item ([#101](https://github.com/entireio/cli/pull/101))

### Thanks

Thanks to @contributor for description of contribution!

Style Rules

  • Sections: Added, Changed, Fixed, Housekeeping, Thanks. Omit empty sections.
  • Each bullet: starts with a dash, concise description, PR link(s) at the end
  • Group related PRs into a single bullet when they're part of the same feature/fix
  • Work-in-progress features: call out explicitly, e.g., "Feature X (work in progress): ..."
  • Known limitations: note inline, e.g., "Note: subagent tracking is not yet supported due to..."
  • Thanks section: only external contributors. Name what they contributed specifically.
  • Dependency bumps: group into a single Housekeeping bullet unless a bump fixes a notable bug
  • PR links: always use full URL format [#N](https://github.com/entireio/cli/pull/N)
  • No trailing period on bullet items
  • Date: use the current date in YYYY-MM-DD format

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.
