A formatter that creates a standard branch or pull-request rename command from a change type, title, and optional pull-request number.

Use it to produce copyable names such as a fix or feature title, with an optional pull-request reference.

It removes the need to format rename commands by hand and can derive missing details from the conversation or branch name.

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.

agentmods

npx agentmods add skills/lexfrei/ccc/genname

Any agent

npx skills add lexfrei/ccc --skill genname

Clone the repo

git clone --depth 1 https://github.com/lexfrei/ccc

Made for: Claude Code.

Or install genname, the plugin that ships this one along with the rest of its 1 skill.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00021	$0.00502
Opus 5	$0.00010	$0.00251
Sonnet 5	$0.00004	$0.00100
Haiku 4.5	$0.00002	$0.00050

Security

Grade A, and why

genname 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 it actually says

Generate a /rename command from arguments. No git or gh calls — pure string formatting.

Arguments

Parse arguments for:

type (required): commit type (fix, feat, refactor, chore, ci, docs, test, perf, build, style)
title (required): branch-style name with dashes/underscores (e.g., e2e-kubernetes-flaky-retry)
PR number (optional): bare number or #N

Inferring from context

If arguments are not provided (or partially provided), infer them from conversation context:

type: extract from branch name prefix (e.g., feat/... → feat, fix/... → fix)
title: extract from branch name after the prefix (e.g., feat/vnc-transport-abstraction → vnc-transport-abstraction)
PR number: extract from conversation context (PR URL, gh pr view output, etc.)

Never ask the user for arguments that can be inferred. If nothing can be inferred and no arguments provided, then ask.

Formatting

Take the type as-is
Convert the title to human-readable: replace - and _ with spaces, capitalize first letter only
If PR number provided, append (PR #N)

Output

Output the rename command as a single copyable line:

/rename <type>: <Title> (PR #<number>)

Or without PR:

/rename <type>: <Title>

Examples

/genname fix e2e-kubernetes-flaky-retry 2062 → /rename fix: E2E kubernetes flaky retry (PR #2062)
/genname feat app-harbor #2055 → /rename feat: App harbor (PR #2055)
/genname refactor e2e-helm-install → /rename refactor: E2E helm install
/genname ci optimize-build-pipeline 100 → /rename ci: Optimize build pipeline (PR #100)

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.
