fix-browser-snap-jetson

fix-browser-snap-jetson is a skill for Claude Code, Codex from Seeed-Projects/Seeed-Jetson-DevelopTool. It costs 85 tokens per session (1,098 once invoked), scanned B, original, MIT.

A repair procedure for browsers installed as snap packages on NVIDIA Jetson devices. Snap packages are applications managed with a security-focused packaging system; the procedure installs a known-compatible snapd version offline and holds it from automatic updates.

In plain words
What is it for?
Use it to check the device, download and install the pinned snapd revision, prevent automatic snapd updates, and verify that the browser can launch.
Why use it?
It addresses browsers that fail to open because Jetson's snapd is too old or incompatible with the browser's security requirements, helping prevent the problem from returning through an update.

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 B, and why

fix-browser-snap-jetson scanned grade B 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 6d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/fix_browser_snap.sh), 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.

Asks for rootmediumPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

How it starts

The opening of the file, as written. The whole thing — 116 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Fix Browser Not Opening on Jetson (snapd Repair)

Browsers distributed as snap packages (Chromium, Firefox) fail to launch on Jetson when the installed snapd is too old or incompatible with the snap's confinement requirements. The fix is to install a known-good snapd revision offline and hold it from auto-updating.

Root cause: Jetson ships with an older snapd that lacks support for newer snap security profiles. The browser snap starts, hits a permission or mount-namespace error, and exits silently.


Execution model

Run one phase at a time. After each phase:

  • Relay all [install] lines to the user.
  • If output contains [STOP] → stop immediately and consult the failure decision tree.
  • If output ends with [OK] → tell the user "Phase N complete" and run the next phase.

The script is idempotent and safe to rerun.


Parameters

Flag Default Notes
--snapd-revision 24724 snapd snap revision to install (change only if advised)
--phase all preflight / download / install / hold / verify / all
--work-dir $HOME/snapd-fix directory for downloaded snap and assert files

Phase commands

Phase 1 — preflight (fast, ~5 s)

Checks snapd status, current version, and whether a browser snap is present.

bash ~/.agents/skills/fix-browser-snap-jetson/scripts/fix_browser_snap.sh \
  --phase preflight

Phase 2 — download (medium, ~1–3 min depending on network)

Downloads the pinned snapd snap and its assertion file from the Snap Store.

bash ~/.agents/skills/fix-browser-snap-jetson/scripts/fix_browser_snap.sh \
  --phase download --snapd-revision 24724

Phase 3 — install (fast, ~30 s)

Acknowledges the assertion and installs the downloaded snapd snap.

bash ~/.agents/skills/fix-browser-snap-jetson/scripts/fix_browser_snap.sh \
  --phase install --snapd-revision 24724

Phase 4 — hold (fast, ~5 s)

Holds snapd at the installed revision so automatic refreshes cannot break it again.

bash ~/.agents/skills/fix-browser-snap-jetson/scripts/fix_browser_snap.sh \
  --phase hold

What ships with it

2 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.

Changes

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.
