upgrade

upgrade is a skill for Claude Code from ai-ecoverse/slicc. It costs 132 tokens per session (2,147 once invoked), scanned A, original, Apache-2.0.

A procedure for handling a SLICC software upgrade event, which occurs when the bundled application version differs from the version used previously.

In plain words
What is it for?
Use it when an upgrade event appears to confirm updating workspace files or dismiss the event without changing them.
Why use it?
It makes the choice to merge new workspace files or leave them unchanged explicit, while preserving local edits through a three-way merge.

    Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.
    Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.

    Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.

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.

Security

Grade A, and why

upgrade scanned grade A with 1 finding 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 1mo 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.

Upgrade

When SLICC boots and discovers that the bundled version (baked into the build at release time from the root package.json) differs from the version it was last seen running, it emits an upgrade lick to the cone. This skill describes how to react.

Event shape

You receive a message like:

[Upgrade Event: 0.4.1→0.5.0]

SLICC was upgraded from `0.4.1` to `0.5.0`.
Released: 2026-04-15T12:00:00Z

Use the **upgrade** skill (...)

The two version strings (from, to) are valid git tags on https://github.com/ai-ecoverse/slicc — the public source repository. The lick message carries a Lick ID: line — you resolve the card with that id.

What to do when you receive an upgrade lick

The runtime renders the upgrade lick as a binary action card automatically — you do not render a sprinkle. The card has exactly two outcomes, which you drive with the lick tools using the Lick ID from the message:

  • lick_confirm → Update workspace files. This runs upgrade apply with the stored release versions. Only confirm once the user has decided to pull the new files.
  • lick_dismiss → clear the card. Use this when the user wants to skip the merge; nothing is changed and the card mutes (✗). The lick will not fire again until the next upgrade.

The card flips to ✓ on confirm / muted ✗ on dismiss. Never auto-run the merge — the user must choose. Reviewing the changelog is not a card action; it is a separate step you can run first to help the user decide.

Before lick_confirm or lick_dismiss, check list_scoops. A scoop that is processing may lose its in-flight work when the runtime moves to the new version. There is no notification — the scoop can look ready / finished, indistinguishable from a clean completion. Wait until every scoop is idle, or expect to re-feed any that were still working. Idle scoops survive.

Which version am I running?

uname -r prints the running version. upgrade status adds the last-booted one, whether a merge is pending, and the exact upgrade apply line to run when it is — that is where --from/--to come from without a card on screen. Realm scripts read globalThis.SLICC_VERSION.
