mcpls changelog.instructions.md

A set of rules for maintaining a software project's changelog, which records notable changes between releases.

In plain words
What is it for?
Use it when adding unreleased changes, documenting public API breakage, or explaining required updates for users of a Rust library.
Why use it?
It prevents breaking changes from being hidden among bug fixes and ensures every entry includes a related pull request or issue number.

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

mcpls changelog.instructions.md 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 2d 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 it actually says

Changelog format

Breaking changes to public APIs must appear under ### Changed with an explicit "Breaking change:" prefix. A ### Fixed entry alone is not sufficient — downstream users scanning the changelog for breakage will miss it.

Additions of #[non_exhaustive] to existing public enums or structs are breaking changes for crates that match exhaustively. Document the required migration (add a wildcard arm, update struct initialisation) in the entry.

Every entry must reference the PR or issue number: (#NNN).

New entries go under ## [Unreleased]. Do not add entries directly under a versioned section — version assignment happens in the release PR.

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.
