changelog

changelog is a command for Claude Code from el-feo/ai-context. It costs 13 tokens per session (1,640 once invoked), scanned A, original, MIT.

A command that builds a changelog from merged pull requests and commits. A changelog is a record of what changed between software versions, grouped into categories such as features and bug fixes.

In plain words
What is it for?
Use it to create or append a changelog between tags, versions, or dates. It reads conventional commits, a standard format for describing change types, and can write the result to a chosen file.
Why use it?
It removes the need to collect release changes by hand and keeps entries tied to pull requests and contributors. It can also highlight breaking changes, which may require users to update their code or setup.

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 6d 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.

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.
