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 | $0.00108 | $0.01605 |
| Opus 5.5 | $0.00043 | $0.00642 |
| Sonnet 5.5 | $0.00022 | $0.00321 |
| Haiku 4.5 | $0.00011 | $0.00161 |
Grade A, and why
update 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 9d 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 — 108 lines — stays where its author put it; the contents beside it link to each section on GitHub.
cc10x Update
Upgrade cc10x with the claude plugin CLI. The CLI owns the plugin registry and the install cache; this skill never edits either one directly and never assumes where they live.
Workflow: Discover installs → Locate the marketplace → (optional) Capture local patches → Refresh marketplace → Update each scope → Re-apply patches → Restart or reload.
Capture comes before the refresh on purpose: marketplace update moves the marketplace checkout to the new version, and the pristine baseline is read from that checkout. The marketplace checkout is often a shallow clone, so the baseline for an installed version is resolvable only when that version's commit is within the checkout depth; for an older install it usually is not. Carry-over is best-effort, and the skill says so plainly when it cannot run.
Phase 1: Discovery
claude plugin list --json
The output is a JSON array. Keep only entries whose id is cc10x@cc10x. Each entry has version, scope (user, project, local, or managed), enabled, installPath, and, for project and local scopes, projectPath.
The same plugin can appear several times: once per scope, and once per project for project and local scopes. Different entries may point at different versions and different installPath values.
If no cc10x@cc10x entry exists → STOP and tell the user cc10x is not installed (install it with claude plugin install cc10x@cc10x).
Show the user one row per entry (scope, projectPath if present, version, installPath). For a project or local entry whose projectPath no longer exists on disk, mark it "skipped: project directory no longer exists"; it cannot be updated from there.
Phase 2: Locate The Marketplace
claude plugin marketplace list --json
Take the entry named cc10x and set LOC to its installLocation. The plugin source is $LOC/plugins/cc10x. If the entry or that directory is missing → STOP and tell the user the marketplace is not registered (claude plugin marketplace add romiluz13/cc10x).
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.

update is a skill published in the GitHub repository romiluz13/cc10x (164 stars, last pushed 10d ago), licensed MIT. It adds 108 tokens to every session and 1,605 once invoked, about $0.0004 per session on Opus 5.5. 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.
Other skills, from other repositories
push-ci
Push to remote and monitor CI. Validates branch safety, executes git push WITH explicit user approval, then monitors CI run status via gh CLI. Use when: user says 'push', 'push and watch CI', 'ship it', 'push-ci'. Not for: committing (use /smart-commit), creating PRs (use /create-pr), merging (use /merge-prep).
bump-version
A procedure for changing a package and plugin version in several project files at the same time.
gh-stack
Native stacked pull requests through the github/gh-stack extension. Detects the extension, installs it only after the user approves, resolves the branch chain, and executes gh stack link / gh stack push / gh stack submit --auto under a per-use AskUserQuestion gate. Use when: opening or refreshing a native stack of…
smart-rebase
Smart partial rebase for squash-merge repositories. Auto-detect which commits to keep/drop when base branch was squash-merged into target. Use when: user says 'rebase', 'partial rebase', 'base already merged', 'smart rebase', or /smart-rebase. Not for: simple git rebase (the developer runs it — no skill executes…
generate-runner
Generate a customized precommit runner for any ecosystem. Use when: non-Node projects need a runner, eject from generic runner, customize runner for project. Not for: running precommit (use /precommit), installing runner (handled by auto-install). Output: customized runner script with eject header.
jira
Jira integration — view issues, generate branches, create tickets, transition status. Use when: user mentions Jira ticket key (XX-123), says /jira, wants to create branch from ticket, create a new ticket, or update Jira status. Not for: GitHub issues (use issue-analyze).
