Installation context

Historical evidence

This report may not describe the currently installable artifact. Open the current Skill page for install guidance.

This report does not block or authorize the manifest or ZIP.

Most static findings are false positives from Markdown backticks, fenced examples, and abbreviated HTTP paths. Confirmed residual risk is limited to intended RunComfy CLI execution and network submission of prompts and bearer-token-authenticated requests. A high-confidence semantic supply-chain issue remains because install instructions reference a different GitHub repository than the reviewed source metadata.

Medium

SKILL.md:10

Ruby/shell backtick execution

Calls `runcomfy run happyhorse/happyhorse-1-0/text-to-video` through

The skill states that it calls the local RunComfy CLI to launch a hosted text-to-video job. The command is fixed and legitimate, but it is still an external process that sends user content outside the local environment.

Medium

SKILL.md:24-26

Ruby/shell backtick execution

```bash

The fenced block contains an npx/global skill installation command. This appears legitimate, but running it executes external tooling and should require explicit user confirmation.

Medium

SKILL.md:44-45

Ruby/shell backtick execution

1. **RunComfy CLI** — `npm i -g @runcomfy/cli`

Line 44 instructs users to install the RunComfy CLI globally through npm. This is a normal prerequisite, but it executes package manager code outside the skill itself.

Medium

SKILL.md:45-46

Ruby/shell backtick execution

2. **RunComfy account** — `runcomfy login` opens a browser device-code flow.

Line 45 instructs users to run runcomfy login, which starts an authentication flow for account access. The action is expected, but it handles credentials and should be user-approved.

Medium

SKILL.md:65-69

Ruby/shell backtick execution

```bash

The command example invokes runcomfy with user-supplied prompt data and an output directory. The CLI target is fixed, but this is real external command execution.

Medium

SKILL.md:73-82

Ruby/shell backtick execution

```bash

The vertical-video example invokes runcomfy with prompt data and generation settings. It is legitimate product behavior, but it still launches a local external command.

Medium

SKILL.md:86-90

Ruby/shell backtick execution

```bash

The cheaper test-pass example invokes runcomfy with prompt data and generation settings. The command is fixed, but an agent could execute it locally if authorized.

Medium

SKILL.md:178-179

Ruby/shell backtick execution

1. The skill invokes `runcomfy run happyhorse/happyhorse-1-0/text-to-video` with a JSON body matchin

The skill explicitly says it invokes runcomfy run with a JSON body. This is intended external CLI behavior rather than arbitrary execution, so the risk is limited but real.

Low

SKILL.md:179

Hardcoded URL

2. The CLI POSTs to `https://model-api.runcomfy.net/v1/models/happyhorse/happyhorse-1-0/text-to-vide

Line 179 identifies a POST to the RunComfy model API using the user bearer token. This is intended service use, but it is real network egress of prompt data and credentials.

Risk findings

Confirmed security concerns are separated from items that still need review.

Confirmed security concerns (1)

RISK-001 High

SKILL.md:20 SKILL.md:25

Repository Mismatch in Installation Instructions

The skill links to and installs from agentspace-so/runcomfy-skills while the reviewed source metadata points to runcomfy-com/skills. This can route users to code that differs from the reviewed source.

The GitHub link and npx install command name agentspace-so/runcomfy-skills, while the report metadata identifies runcomfy-com/skills as the reviewed source. This is a clear supply-chain consistency issue, although ownership relationship is not proven from the file alone.

Remediation

Suggested fixes recorded by this audit. Applying them is the maintainer’s responsibility.

FIX-001
High
Repository mismatch in public links and install command.

Update the GitHub link and npx install command to the reviewed repository, or document a verified ownership relationship between both repositories.
FIX-002
Medium
External RunComfy CLI execution is part of normal use.

Require explicit user approval before running npx, npm, runcomfy login, or runcomfy run commands from this skill.
FIX-003
Low
Prompts and bearer-token-authenticated requests are sent to RunComfy.

Disclose the external API submission clearly and avoid sending confidential prompts unless the user accepts that transfer.
FIX-004
Low
RunComfy token storage is security-sensitive.

Keep token files owner-only, prefer environment-scoped tokens in CI, and never print token file contents in generated instructions.
