cf-environment

cf-environment is a skill for Claude Code from teachskillofskills-ai/ContentForge-techshu. It costs 156 tokens per session (1,965 once invoked), scanned A, a copy of cf-environment, MIT.

An environment check that identifies where ContentForge is running, such as a local computer or a restricted online workspace. It reports which connections, file locations, and session-resume features work there.

In plain words
What is it for?
Use it before long content jobs, when files are not appearing in Documents, or when deciding how to connect services in Cowork or Claude Code.
Why use it?
ContentForge behaves differently depending on where it runs, so this prevents incorrect expectations about saved files, connectors, and continuing work later.

Skill for Claude Code

Written for Claude Code: argument-hint in frontmatter. Also seen: reads .claude/ paths; mentions Claude Code.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python scripts/plugin-metadata.py --section environment.

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

cf-environment 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 9d 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.

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

/contentforge:cf-environment

Detect where ContentForge is running and report which of its capabilities work in that environment. ContentForge has different real-world behavior on each surface because filesystem access, MCP transports, and subprocess invocation all differ.

When to use this skill

  • User asks "will my files actually save to my Documents folder?"
  • User asks "does this work in Cowork?"
  • User reports that ~/Documents/ContentForge/ is empty after a run
  • Before kicking off a long (20-60 min) content pipeline, to set expectations
  • During brand-setup, to decide between MCP-Drive and service-account routes

Behavior

Step 1 — Run the environment probe

python scripts/plugin-metadata.py --section environment

This returns JSON with environment (one of cowork-sandbox, claude-code-windows, claude-code-mac, claude-code-linux, linux-sandbox-uncertain, unknown — six possible values), filesystem indicators, a cowork_warning field that's non-null when a sandbox (confirmed or suspected) is detected, and a signals object (strong / weak lists) showing exactly which detection heuristics fired — useful for --verbose or when a user disputes the classification.

Step 2 — Present the capability matrix for the detected environment

Render one of the matrices below based on the JSON environment. The six values map to three matrices: cowork-sandbox AND linux-sandbox-uncertain both use the Cowork matrix (uncertain gets a one-line caveat first, see below); claude-code-windows / -mac / -linux share the local matrix; unknown gets its own fallback.

cowork-sandbox

Cowork is the recommended environment for teams as of v3.12.9 — it has the friendliest UX, lowest setup friction, and works for non-CLI users. But it requires one extra setup step (connecting Google Drive) because the sandbox filesystem doesn't persist. After Drive is wired, everything works.

Also check: is a Drive MCP available in this session? Scan your available tools for mcp__*drive* or the Anthropic-platform Drive integration. The capability matrix below splits on that.

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.
