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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00174 | $0.08089 |
| Opus 5 | $0.00087 | $0.04045 |
| Sonnet 5 | $0.00035 | $0.01618 |
| Haiku 4.5 | $0.00017 | $0.00809 |
Grade A, and why
change-description-authoring 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.
How it starts
The opening of the file, as written. The whole thing — 559 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Authoring a change description
This skill governs what a change description says, in what order, and for whom. Wording, tense,
mood, sentence length, punctuation, and dialect belong to english-developer-style; load it too,
and let it own the sentences. Subject length limits, prefix grammar, and trailer syntax belong to
commitlint or the platform, not to a prompt.
A change description is three artifacts written at once: the commit message, the pull request description, and the changelog entry. They are read by five readers, at five different moments, holding five different things. The rules below name the reader every time, because the same sentence is essential to one reader and noise to another, and the only way to decide is to ask whose question it answers.
1. The correction that matters most
Write for the readers who are not in the room. The reviewer can ask; the other four cannot. The
archaeologist holds a line of code years later, the on-call engineer holds a stack trace at 3 a.m.,
the upgrading user holds release notes, and the backporter holds a list of subjects. Each of them
has
one artifact and one search string, and a description that answers the reviewer's questions in the
pull request while leaving git log with a title has served the one reader who needed it least.
| Reader | Holds | Opens | Asks |
|---|---|---|---|
| R1 Reviewing maintainer | The diff | The pull request description | Was something wrong? Is this behavior right? How was it checked? What is left out? |
| R2 Archaeologist | A line of code, via git blame |
The commit message | Why does this exist? Why this approach? Which constraint forced it? |
| R3 On-call engineer | A stack trace or a log line, and a version | The changelog, then the commit a bisect reaches | Is this my incident? What triggers it? Am I on an affected version? Is there a workaround? |
| R4 Upgrading user | The version they run and the one they want | The release notes | What changed that I can observe? Is it compatible? What must I do? |
| R5 Backporter | A maintenance branch | Labels, trailers, and the subject list | Is this a fix? How severe? Which versions? Does it need another change first? |
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.

change-description-authoring is a skill published in the GitHub repository Netcracker/qubership-ai-packages (4 stars, last pushed 2d ago), licensed Apache-2.0. It adds 174 tokens to every session and 8,089 once invoked, about $0.0009 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-05.
