Getting it into your agent
There is no command for this one: it runs only inside a plugin, and the catalogue could not identify which plugin ships it. The source is linked below.

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 | $0.00098 | $0.02188 |
| Opus 5 | $0.00049 | $0.01094 |
| Sonnet 5 | $0.00020 | $0.00438 |
| Haiku 4.5 | $0.00010 | $0.00219 |
Grade A, and why
migration 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 12d 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.

Cumulocity Web SDK Migration Skill
Overview
This skill guides you through a full migration of a Cumulocity Web SDK application from one version to another. It combines three tools into a single repeatable workflow:
- ui-breaking-changes-cli — detect every breaking change between the two SDK versions
new-appskill — scaffold a clean reference project at the target versioncode-quality-analysisskill — verify the migrated code meets quality standards
Prerequisites
Before starting, identify:
| Variable | Description | Example |
|---|---|---|
FROM_VERSION |
Your current @c8y/ngx-components version |
y2025-lts, 1021.22.50 |
TO_VERSION |
The target SDK version | y2026-lts, cd |
PROJECT_ROOT |
Absolute path to the app you are migrating | /home/user/my-c8y-app |
To find your current version:
cat package.json | grep '@c8y/ngx-components'
Step 1 — Detect Breaking Changes
Use the ui-breaking-changes-cli to get a full report of everything that changed between
your current and target versions.
Install the CLI
Download the latest .tgz from the
GitHub Releases page,
then extract and run it directly — no global install required:
tar -xzf c8y-breaking-changes-cli-v*.*.*.tgz
Alternatively, build from source:
git clone https://github.com/Cumulocity-IoT/ui-breaking-changes-cli.git
cd ui-breaking-changes-cli
pnpm install
pnpm build
Run the report
The CLI accepts several version alias formats for --from and --to:
| Format | Examples |
|---|---|
| LTS alias | y2025-lts, y2026-lts |
| Year alias | y2025, y2026 |
| Minor / stable line | 1021, 1023, 1021.22 |
| Full patch version | 1021.22.145, 1023.13.2 |
| Continuous delivery | cd — resolves to the current latest tag on npm |
Version format: use the
y-prefixed dist-tag form (y2026-lts) — this is whatnpm dist-tags @c8y/websdkwill show and what the breaking-changes-cli resolves against. The un-prefixed form (2026-lts) is also accepted by the CLI but is not a real npm tag.
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.

migration is a skill published in the GitHub repository Cumulocity-IoT/cumulocity-skills (5 stars, last pushed 10d ago), licensed Apache-2.0. It adds 98 tokens to every session and 2,188 once invoked, about $0.0005 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 2026-08-31.
