setup-deps

setup-deps is a skill for Claude Code from Sassy-Dog/sassydog-skills. It costs 178 tokens per session (6,705 once invoked), scanned A, original, Apache-2.0.

A repository-specific generator for Dependabot, GitHub’s tool for proposing dependency updates, and related update workflows.

In plain words
What is it for?
Use it to detect package ecosystems, create grouped Dependabot configuration, and add supported auto-merge or lockfile workflows.
Why use it?
It reduces manual dependency maintenance and can group updates or automate parts of the review process when the repository meets the required conditions.

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

setup-deps 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 6d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/detect-ecosystems.sh, scripts/lib-ecosystems.sh, scripts/render-dependabot.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.

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

Setup Deps

Generator/refresher for a repo's dependency automation, in the same family as setup-config and setup-hooks: detect the stack, render from templates, reconcile only what this generator owns.

It renders up to three things:

File When
.github/dependabot.yml always — grouped, one entry per (ecosystem, directory)
.github/workflows/dependabot-auto-merge.yml when the repo has a merge gate AND is not public — two preconditions, see §2
.github/workflows/dependabot-bun-lockfile.yml legacy fallback — only when npm has lockfile_risk (binary bun.lockb, or a repo deliberately on npm + sync) AND the repo is not public; a text bun.lock renders the native bun ecosystem instead, no sync workflow. One per bun install root, not one per repo
.github/workflows/dependabot-pod-lockfile.yml when cocoapods is detected and the app's ios/Podfile.lock is tracked (see §3) AND the repo is not public

Bundled scripts (scripts/): detect-ecosystems.sh (probe), render-dependabot.sh (render), validate-dependabot.sh (post-render assertion + divergence check), and lib-ecosystems.sh — the one ecosystem table all three read, so the validator can never agree with a renderer that is wrong.

Ownership marker: the generated-by: comment on the first non-blank line after the YAML document start. Re-runs reconcile only files carrying that marker — a hand-written dependabot.yml is reported and left alone, never overwritten.

Ownership matching is deliberately wide: accept EITHER marker namespace — the current sassy-dog: prefix and the pre-rename ai-agent-skills: prefix (plugin ≤ 2026.8.20) — paired with ANY producer name this generator has ever emitted: setup-deps (current), refresh-deps (plugin ≤ 2026.8.39), and refresh-sassydog-deps (plugin ≤ 2026.7.21). A file is owned when its marker matches:

generated-by: (sassy-dog|ai-agent-skills):(setup-deps|refresh-deps|refresh-sassydog-deps)

All six namespace × producer-name combinations are owned. The plugin rename moved the namespace before the colon; the two generator renames moved the name after it. This matters more here than almost anywhere else in the plugin: the marker is committed inside every consumer repo, in .github/dependabot.yml and each dependency workflow, so a matcher narrowed to the current producer name would classify every pre-rename file as hand-written and refuse to reconcile it — and it would fail silently, because the contract above is report-and-skip, not error. Normalise the marker to the current sassy-dog:setup-deps form on write (expect a one-line diff per file on a pre-rename repo's first re-run; that is the intended outcome, not drift).
