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 | $0.00046 | $0.02179 |
| Opus 5.5 | $0.00018 | $0.00872 |
| Sonnet 5.5 | $0.00009 | $0.00436 |
| Haiku 4.5 | $0.00005 | $0.00218 |
Grade C, and why
devcontainer-setup scanned grade C 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 1mo 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.
- Python: if `pyproject.toml` declares a Python version different from the base default, set it in the Dockerfile via `uv python install <version> --default`. Add extensions `ms-python.python`, `ms-python.vscode-pylance` Copies of this mod

How it starts
The opening of the file, as written. The whole thing — 61 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Devcontainer setup
Contract
| Field | Bound contract |
|---|---|
| Trigger | The user asks to add a new devcontainer or isolated Claude Code development environment to a repository that does not already have one, for Python, Node/TypeScript, Rust, Go, or a supported combination. |
| Authority | Reversible local: writes only the repository's .devcontainer/ directory; rollback is version control. No remote mutation. No container is built, launched, published, or pushed. |
| Side effect | Creates or replaces the five generated files under .devcontainer (Dockerfile, devcontainer.json, post_install.py, .zshrc, and install.sh) with project substitutions and merged language-specific features, settings, extensions, commands, and persistent-volume declarations. |
| Done | All template placeholders are resolved; devcontainer.json is valid; every detected language is represented without duplicate configuration; postCreateCommand composes all required setup commands; the security mounts and token-forwarding contract are explicit; and the user receives both VS Code and CLI startup instructions without claiming the container was built or launched unless it was. |
Inputs
Required: the repository root to scan for language manifests and to write .devcontainer/.
Optional, supplied by the user when known: a human-readable project name (otherwise inferred), a preferred Python version (otherwise the default from the base template), and a package manager choice for Node/TypeScript (otherwise detected from the lockfile).
Procedure
-
Reject modification requests. If
.devcontainer/already exists, stop: this skill only adds a new devcontainer. Direct the user to edit the existing configuration. Do not trigger for general Docker, production container, or container lifecycle questions. Done when: the skill confirms.devcontainer/is absent, or stops and directs the user to edit the existing config. -
Infer project name and slug. Probe in order and use the first match:
package.jsonnamefield,pyproject.tomlproject.name,Cargo.tomlpackage.name,go.modmodule path (last segment after/), then the repository directory name as fallback. Derive the slug by lowercasing and replacing spaces and the underscore with hyphens. Keep the human-readable name distinct from the slug. Done when: a human-readable name and a derived slug are recorded.
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.

devcontainer-setup is a skill published in the GitHub repository OutlineDriven/outline-driven-development (55 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 46 tokens to every session and 2,179 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
