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.

SkillSpector: 1 finding, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00018 | $0.00473 |
| Opus 5 | $0.00009 | $0.00236 |
| Sonnet 5 | $0.00004 | $0.00095 |
| Haiku 4.5 | $0.00002 | $0.00047 |
Grade A, and why
dependency-management 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.
What it actually says
Dependency Management
Safely manage project dependencies at scale.
Version Strategy
Pinning Approaches
| Strategy | Format | Risk | Best For |
|---|---|---|---|
| Exact | 1.2.3 |
Low | Docker, CI, production |
| Caret | ^1.2.3 |
Medium | Libraries, apps with good tests |
| Tilde | ~1.2.3 |
Low-Medium | Conservative updates |
| Range | >=1.2.3 <2.0.0 |
High | Rare, legacy |
| Floating | * |
Very High | Never in production |
Rule: Pin exact versions for production, caret for libraries.
Vulnerability Scanning
Tools
- npm audit /
yarn audit— quick JS check - Dependabot — GitHub-native, auto PRs
- Snyk — deeper scanning, prioritization
- Trivy — container scanning
- OWASP Dependency-Check — Java/.NET
Workflow
- Scan on every PR (fail on critical/high)
- Weekly full scan of all repos
- Patch critical (<7 days), high (<30 days)
- Track CVEs by severity in dashboard
- SBOM generation per release
Monorepo Patterns
- Use workspaces (npm/yarn/pnpm workspaces)
- Shared dependency versions (single source of truth)
- Independent vs locked version strategy
- Deduplicate (npx dedupe after major changes)
- Audit tree to find conflicting transitive deps
Upgrade Workflow
- Check changelog for breaking changes
- Run tests (you have tests, right?)
- Upgrade one major version at a time
- Run full test suite + build
- Deploy to staging, verify
- Monitor for regressions (logs, metrics, errors)
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-management is a skill published in the GitHub repository cosmicstack-labs/mercury-agent-skills (471 stars, last pushed 15d ago), licensed MIT. It adds 18 tokens to every session and 473 once invoked, about $0.0001 per session on Opus 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.
