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 | $0.00073 | $0.01140 |
| Opus 5.5 | $0.00029 | $0.00456 |
| Sonnet 5.5 | $0.00015 | $0.00228 |
| Haiku 4.5 | $0.00007 | $0.00114 |
Grade A, and why
dependency-review 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 2mo 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 — 137 lines — stays where its author put it; the contents beside it link to each section on GitHub.
dependency-review
Decide whether to add a proposed dependency before it is added. Do not install anything or modify project files while using this skill.
Activate when
- A new runtime or development dependency is proposed
- An existing dependency upgrade would pull new transitive packages
- A failing build suggests adding a package to resolve it
Do not activate when
- The package is already a project dependency and no version changes
- The task is a code change with no new dependency -> use
implement-minimal - The task is a failing test unrelated to dependencies -> use
test-and-debug
Required inputs
- The exact package name and, if known, the version or range
- The problem the dependency is meant to solve
- Whether it is a runtime or development dependency
Low-resource policy
Read the first of these that exists, then follow it:
${CLAUDE_PROJECT_DIR}/.claude/shared/LOW_RESOURCE.md$HOME/.claude/shared/LOW_RESOURCE.md
If neither exists, apply this fallback: run one expensive command at a time, prefer the narrowest validation, disable watch mode, reuse existing environments, and run full validation only at a milestone boundary. Do not scan the whole filesystem to locate the policy.
Context-efficiency policy
Read the first of these that exists, then follow it:
${CLAUDE_PROJECT_DIR}/.claude/shared/CONTEXT_EFFICIENCY.md$HOME/.claude/shared/CONTEXT_EFFICIENCY.md
If neither exists, apply this fallback: select files before reading; use targeted searches and bounded ranges; do not preload references; do not reread unchanged files; finish one atomic increment and stop; create a compact handoff before context is exhausted.
Facts that must not be assumed
- The package manager and lockfile in use
- That the package is actively maintained
- That the license is compatible with public release
- The size of the transitive dependency tree
Preflight
- Identify the ecosystem and manifest -> references/ecosystem-review.md
- Read the existing manifest to see current dependencies and conventions
- Determine whether a current dependency or platform API already solves it
What ships with it
3 files 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.

dependency-review is a skill published in the GitHub repository olgaiv39/claude-oss-skills (13 stars, last pushed 3mo ago), licensed MIT. It adds 73 tokens to every session and 1,140 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
