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 | $0.00157 | $0.05478 |
| Opus 5 | $0.00078 | $0.02739 |
| Sonnet 5 | $0.00031 | $0.01096 |
| Haiku 4.5 | $0.00016 | $0.00548 |
Grade A, and why
multi-version-compliance 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 4d 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 — 403 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Multi-version compliance for Nx plugins
What this is
The nx migrate --first-party-only flag lets users upgrade Nx without
dragging the managed third-party ecosystems (Angular, Cypress, Playwright,
Jest, Vitest, ESLint, etc.) along. For that to be safe, every first-party
plugin must keep working across its declared support window — not silently
fall through to the latest install constants on older workspaces, not
silently break on newer ones.
Source-of-truth split:
| Source | Owns |
|---|---|
| Linear milestone "Multi-version supported across plugins" (project NXC-4072) | What's wrong per plugin, the resolved support window, open human decisions. Per-plugin tasks NXC-4381..NXC-4410 (P1–P29). |
| This skill | How to implement the canonical shape, code-level anti-patterns, gotchas, findings doc shape (no-task case). |
The skill is the gap-closer: it accepts a Linear task, parses it, drives the fix. When no task exists for the plugin, fix mode runs discovery in Phase 1–2 and produces a findings doc that mirrors a Linear task body — so the user can file it as a new task before proceeding.
Reference PRs (the canonical shape):
#35587—@nx/angular— merged. Set the precedent. IntroducedthrowForUnsupportedVersion.#35642—@nx/playwright— merged. Generalized the shared helpers into@nx/devkit/internal. Established executor / runtime feature- gating.#35670—@nx/cypress— merged. AddedexcludeGeneratorsto the parameterized test helper.#35671—@nx/vitest— open at time of writing. Demonstrates "drop phantom peer-range claim" and "declared floor < effective floor" patterns.
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.

multi-version-compliance is a skill published in the GitHub repository nrwl/nx (29,301 stars, last pushed today), licensed MIT. It adds 157 tokens to every session and 5,478 once invoked, about $0.0008 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.
