skill-resolve

skill-resolve is a skill for Claude Code, Codex from cintia09/CodeNook. It costs 0 tokens per session (377 once invoked), scanned A, original, MIT.

A resolver that searches for a named skill in four locations, from plugin-specific copies through workspace custom skills to built-in skills. It returns JSON describing the matching file or the paths it checked.

In plain words
What is it for?
Use it to resolve a skill name for a plugin and workspace, while rejecting unsafe names containing path traversal or unsupported characters.
Why use it?
It lets sub-agents find the intended instructions predictably without relying on an ambiguous file location.

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.

Security

Grade A, and why

skill-resolve 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 (_resolve_skill.py, resolve-skill.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

skill-resolve (builtin skill)

Role

Resolve a skill name against the 4-tier lookup chain so sub-agents self-bootstrap deterministically. Implements implementation.md §M5.5.

Lookup order

  1. plugin_local — <ws>/.codenook/memory/<plugin>/skills/<name>/SKILL.md
  2. plugin_shipped — <ws>/.codenook/plugins/<plugin>/skills/<name>/SKILL.md
  3. workspace_custom — <ws>/.codenook/skills/custom/<name>/SKILL.md
  4. builtin — <core_dir>/skills/builtin/<name>/SKILL.md

Where <core_dir> comes from the CODENOOK_CORE_DIR environment variable, falling back to the directory containing resolve-skill.sh's skills/builtin ancestor.

CLI

resolve-skill.sh --name <skill> --plugin <plugin> --workspace <ws> [--json]

Output is always JSON (the --json flag is accepted for symmetry; default is JSON anyway).

Output

Found:

{ "found": true, "name": "...", "path": "...", "tier": "plugin_local" }

Not found (exit 1):

{ "found": false, "name": "...", "candidates": [ "...", "...", "...", "..." ] }

Safety

  • --name is rejected if it contains /, .., or any character outside [A-Za-z0-9._-]. Exit code 2 (usage).
  • Each candidate path is resolved + a containment check ensures it sits under the workspace OR the core directory before being returned.
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.
