list_skill

A procedure for listing available ACLIx skills by scanning skill directories for their SKILL.md entry files. It uses a bundled Python scanner and has a restricted shell fallback.

In plain words
What is it for?
Use it when someone asks to list, show, enumerate, or otherwise inventory the available ACLIx skills.
Why use it?
It provides one inventory of the skills that are actually present, instead of relying on incomplete memory or manual directory checks.

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.

Made for: Claude Code, Codex.

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

list_skill 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/scanner.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.

How it starts

The opening of the file, as written. The whole thing — 94 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Deliver a single, authoritative inventory of filesystem-based ACLIx skills (directories that contain a SKILL.md entrypoint). Prefer the bundled python scanner; if that path is unavailable, continue automatically via a constrained shell fallback—never stop at “Python missing” without producing a table for the user.

Standard Operating Procedure

Trigger

Activate this procedure whenever the user asks to list skills, show available skills, enumerate skills, or any equivalent inventory request.


1. Primary method (Python engine)

  1. Read the injected anchor at the very top of the skill payload returned by read_skill. Extract the absolute path from the line:

    • [Skill Directory: <absolute_path>]
    • Hereafter, call this value INJECTED_SKILL_DIR (it is the directory that contains this skill’s SKILL.md).
  2. Invoke the python tool with:

    • scriptPath: INJECTED_SKILL_DIR + /scripts/scanner.py (no trailing slash issues; normalize mentally to a single absolute path).
    • code: omit.
    • args: omit for the default behavior (scanner walks ~/.aclix/skills and ./.aclix/skills relative to the agent process cwd). If the user requests a single alternate filesystem root, pass one argument: that directory path (the script treats sys.argv[1] as the sole scan root).
  3. Success path — stdout is one JSON object from json.dumps. Parse it. Expect:

    • skills: array of records with at least folder_name, skill_directory, skill_md_path, name, description (any of the metadata fields may be JSON null).
  4. Failure of the primary method — Treat any of the following as failure: tool error string, non-JSON stdout, empty/corrupt JSON, or a message indicating python3 / python could not be executed. Do not apologize at length, do not ask the user whether fallback is allowed, and do not abort the task. Immediately continue to Section 2.

Files

What ships with it

1 file 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.

list_skill is a skill published in the GitHub repository AliasJeff/ACLIx (23 stars, last pushed 4mo ago), licensed MIT. It adds 16 tokens to every session and 1,452 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.
