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 | $0.00029 | $0.00278 |
| Opus 5.5 | $0.00012 | $0.00111 |
| Sonnet 5.5 | $0.00006 | $0.00056 |
| Haiku 4.5 | $0.00003 | $0.00028 |
Grade A, and why
dependency-upgrade-safety 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.
What it actually says
Dependency Upgrade Safety
Goal
Upgrade or fix dependencies without introducing avoidable breakage.
When to use
Use for npm, pnpm, yarn, lockfile conflicts, peer dependency errors, security patches, and dependency cleanup.
When not to use
Do not use for app logic bugs unrelated to dependency versions.
Inputs
Inspect package manifests, lockfiles, error output, package manager, framework versions, and related build/test commands.
Workflow
- Identify the package manager and lockfile.
- Read the exact install or build error.
- Check peer dependency constraints.
- Prefer minimal version changes.
- Avoid force flags unless the user accepts risk.
- Update lockfile consistently.
- Run install, build, and relevant tests.
- Document any breaking changes or deferred upgrades.
Quality bar
A good dependency change is minimal, reproducible, and compatible with the project stack.
Validation
Run install, package manager checks, lint/typecheck/tests/build as available.
Final response
Report package changes, reason for version choices, validation commands, and remaining risks.
What ships with it
4 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-upgrade-safety is a skill published in the GitHub repository YankielDBC2/codex-skills-library (13 stars, last pushed 3mo ago), licensed MIT. It adds 29 tokens to every session and 278 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it A with 0 findings.
