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 | $0.00020 | $0.04370 |
| Opus 5 | $0.00010 | $0.02185 |
| Sonnet 5 | $0.00004 | $0.00874 |
| Haiku 4.5 | $0.00002 | $0.00437 |
Grade A, and why
goose-desktop-env-fix 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 8d 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.

Goose Desktop Environment Fix
Fix the Goose Desktop shell tool so that shell commands run with the
full user environment — including devbox/nix-installed tools, crc/oc,
cargo, sdkman, and custom exports.
Problem
Goose Desktop's shell tool runs non-interactive, non-login bash
shells (bash -c "<command>"). Bash only sources ~/.bashrc for
interactive shells, so all user environment setup is missing:
| Shell Type | Files Sourced |
|---|---|
| Login + Interactive | ~/.bash_profile → ~/.bashrc |
| Interactive (non-login) | ~/.bashrc |
| Non-interactive, non-login | Only $BASH_ENV (if set) |
Goose Desktop falls into the third category, resulting in:
- Bare
PATH(missing devbox/nix, cargo, crc/oc, sdkman paths) - Missing environment variables
- Tools like
gh,oc,hey,javanot found
Additionally, Goose Desktop on Fedora/GNOME may have a user-level
.desktop file override at ~/.local/share/applications/Goose.desktop
that hardcodes PATH via Exec=env PATH=..., preventing
environment.d variables from reaching the Goose process.
Root Causes
- Bash sourcing rules — non-interactive shells don't source
~/.bashrc - Nix double-source guard —
nix-daemon.shsets__ETC_PROFILE_NIX_SOURCED=1and skips if already set. The GNOME session sets this during login, but the Goose.desktopfile overridesPATHwithout nix paths, so nix is "sourced" but its paths are missing. - Desktop file override — the user-level
.desktopfile'sExec=env PATH=...line overrides session environment variables set via~/.config/environment.d/ - Devbox
shellenvrecursive fork bomb —devbox global shellenvspawns a bash subprocess to compute the environment. That subprocess sources~/.bashrc(viaBASH_ENVor thegoose-shellwrapper), which callsdevbox global shellenvagain, creating an infinite recursion. This rapidly spawns thousands of processes (observed: 5,763+), consuming CPU and risking system instability.
What ships with it
1 file 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.
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.

goose-desktop-env-fix is a skill published in the GitHub repository rhtevan/agentfs (2 stars, last pushed today), licensed Apache-2.0. It adds 20 tokens to every session and 4,370 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
