app-upgrades

app-upgrades is a skill for Claude Code from CrowdStrike/foundry-skills. It costs 123 tokens per session (1,592 once invoked), scanned A, original, MIT.

An in-place upgrade process for an app that was originally installed from a Falcon Foundry template. It applies a newer template version while retaining the installed app's identifiers.

In plain words
What is it for?
Use it to update a template-installed app from an archive, directory, or repository version, while checking the upgrade in a separate working directory.
Why use it?
It avoids creating a second app when the template is updated. It also makes clear that customer changes and added artifacts may be overwritten or removed, so confirmation is needed first.

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

app-upgrades 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 today.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/upgrade_manifest.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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 — 77 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Upgrading Template-Installed Apps

A Falcon Foundry template installs an app into a CID once. Nothing updates it when the template changes, and deploying the new template as-is creates a second app, because template manifests ship without IDs. This skill copies the installed app's IDs into the new version so foundry apps deploy updates the app the customer already has.

The template is the source of truth. The app keeps its current name. Changes the customer made after installing are overwritten; artifacts only the customer added are removed. Stop and confirm before anything is removed.

Inputs: the app ID, and optionally the new version as a .tar.gz/.tgz or .zip archive, an unpacked directory, or owner/repo[@ref]. With no version given, the skill finds the template by the app's name and uses its GitHub repo's default branch.

The script is scripts/upgrade_manifest.py in this skill's directory. It needs pyyaml, and crowdstrike-falconpy for find-template. Run it from a virtual environment outside the app directory.

Procedure

Use a new scratch directory per upgrade ($WORK below). Never sync or extract into the user's working copy.

  1. Confirm the target. foundry profile list --no-prompt shows the active profile; the app must belong to its CID. foundry apps list must show the app ID. If not, ask which profile to foundry profile activate.

  2. Sync the deployed app. list-deployments only runs next to a manifest.yml with an app_id and a name, even with --app-id, and an app installed from the console has no local directory. Give it a stub, take the newest version whose state is Successful, and sync that into scratch (sync runs from anywhere):

    mkdir -p "$WORK/stub" && printf 'app_id: %s\nname: stub\n' <app-id> > "$WORK/stub/manifest.yml"
(cd "$WORK/stub" && foundry apps list-deployments --app-id <app-id>)
foundry apps sync --app-id <app-id> --deployment-version <version> -d "$WORK/deployed" --replace-all --no-git --no-prompt

    No successful deployments means there's nothing to upgrade from; tell the user.

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.
