What is plugin-deps-check?

A version-compatibility checker for CodeNook plugins. It compares the plugin's required core version with the version currently running, using standard version comparisons.

Use it to verify requirements such as a minimum version, maximum version, exact version, or a range of allowed versions.

It catches plugins that require a different core version before they are installed.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00000	$0.00468
Opus 5.5	$0.00000	$0.00187
Sonnet 5.5	$0.00000	$0.00094
Haiku 4.5	$0.00000	$0.00047

Security

Grade A, and why

plugin-deps-check 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.

The scan reads SKILL.md. This mod also ships 2 executable files (_deps_check.py, deps-check.py), 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.

What it actually says

plugin-deps-check — Install gate G06

Verifies the plugin's declared requires.core_version constraint against the running core VERSION.

CLI

deps-check.sh --src <dir> [--core-version <v>] [--json]

If --core-version is omitted, the core VERSION file shipped with this repo (skills/codenook-core/VERSION) is read.

Constraint syntax

Comma-separated comparator list (logical AND):

>=0.2.0,<1.0.0
>=0.2.0
==0.2.0

Supported operators: >=, <=, >, <, ==, =, !=. Operands must be valid SemVer 2.0 strings.

⚠️ NOTE — SemVer pre-release precedence (M2 caveat)

Per SemVer §11.4, a version with a pre-release identifier has lower precedence than the same version without one:

0.2.0-m2.1  <  0.2.0-m2.2  <  0.2.0

While core is on 0.2.0-m2.x (M2 milestone pre-release), plugin authors who want to require "M2 or newer" must spell their constraint with an explicit pre-release floor — >=0.2.0 would reject every M2 build because every M2 build sorts before 0.2.0.

# plugin.yaml — correct for M2-era plugins:
requires:
  core_version: '>=0.2.0-m2'    # ✅ accepts 0.2.0-m2.1, 0.2.0-m2.2, 0.2.0, ...

# plugin.yaml — WRONG during M2:
requires:
  core_version: '>=0.2.0'       # ❌ rejects every 0.2.0-m2.x build

Once core ships final 0.2.0, plain >=0.2.0 becomes correct.

Files

What ships with it

2 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.

Changes

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.
