Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00056 | $0.02013 |
| Opus 5 | $0.00028 | $0.01007 |
| Sonnet 5 | $0.00011 | $0.00403 |
| Haiku 4.5 | $0.00006 | $0.00201 |
Grade A, and why
new 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 7d 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 — 263 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Release Workflow
Creates GitHub, GitLab, or Gitea releases with auto-versioning and release notes generation.
Activation Triggers
- "create release", "cut release", "new release"
- "publish version", "bump version", "new version"
- "tag and release"
Scripts
Helper scripts in skill's scripts/ directory (use ${CLAUDE_PLUGIN_ROOT} for path resolution):
detect-platform.sh- outputsgithub,gitlab, orgiteacalc-version.sh <type>- outputs new version (e.g.,v1.2.3)get-notes.sh <platform>- outputs release notes (PRs/MRs or commits)
Every helper exits non-zero and prints the reason on stderr. If any of Steps 2, 5 or 6
fails, report that text to the user and abort the workflow - do not continue with an
empty value. get-notes.sh in particular fails when the forge CLI is missing,
unauthenticated or rate-limited; continuing there publishes a release whose notes list
none of its PRs.
On Gitea, get-notes.sh collects no PRs and returns commit-derived notes with a warning
on stderr, because tea pr list exposes neither a merged flag nor a merge timestamp. That warning
is not a failure - show it to the user with the preview in Step 8 and carry on.
Workflow
Step 1: Ask Release Type
Use AskUserQuestion tool to get release type:
{
"questions": [{
"question": "What type of release is this?",
"header": "Version",
"options": [
{"label": "Hotfix", "description": "Bug fixes (1.2.3 → 1.2.4)"},
{"label": "Minor", "description": "New features (1.2.3 → 1.3.0)"},
{"label": "Major", "description": "Breaking changes (1.2.3 → 2.0.0)"}
],
"multiSelect": false
}]
}
Step 2: Detect Platform
platform=$(bash ${CLAUDE_PLUGIN_ROOT}/skills/new/scripts/detect-platform.sh)
Step 3: Validate Prerequisites
# working tree must be clean
if [ -n "$(git status --porcelain)" ]; then
echo "error: uncommitted changes - commit or stash first"
fi
# sync with remote (--tags ensures all remote tags are fetched)
git fetch origin --tags
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

new is a skill published in the GitHub repository umputun/cc-thingz (467 stars, last pushed 13d ago), licensed MIT. It adds 56 tokens to every session and 2,013 once invoked, about $0.0003 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 2026-08-30.
