skill-131

skill-131 is a skill for Claude Code, Codex from legendtkl/agentic-skill-router. It costs 21 tokens per session (715 once invoked), scanned A, original, MIT.

Utilities for transforming PDDL planning domains and problem files to improve how planning states are represented. PDDL is a language for describing actions, goals, and constraints for automated planning.

In plain words
What is it for?
Use them to load a PDDL domain, transform it, and optimize a related planning problem.
Why use it?
They can make planning inputs more efficient to process while reporting whether optimization succeeded.

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-131 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 7d 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.

Requirements for Outputs

General Guidelines

  • PDDL domain files must meet optimization standards.
  • Problem files must adhere to the transformations specified.
  • Outputs should clearly indicate optimization metrics.

Optimization Behavior

  • Optimization processes should complete within a predefined time.
  • If no optimization is possible, return an indication of failure.

PDDL Optimization Utilities

1. Load and Transform Domain

load-and-transform-domain(domain_path)

Description:
Loads a PDDL domain file and applies transformations to optimize the state representation.

Parameters:

  • domain_path (str): Path to the PDDL domain file.

Returns:

  • optimized_domain: A transformed domain for better efficiency.

Example:

optimized_domain = load_and_transform_domain("domain.pddl")

Notes:

  • Utilizes unified_planning.io.PDDLTransformer.
  • Throws an error if transformation fails.

2. Optimize Problem

optimize-problem(problem_path, optimized_domain)

Description: Optimizes the specified problem based on the optimized domain loaded previously.

Parameters:

  • problem_path (str): Path to the PDDL problem file.
  • optimized_domain: The transformed domain.

Returns:

  • optimized_problem: An optimized problem object ready for planning.

Example:

optimized_problem = optimize_problem("task01.pddl", optimized_domain)

Notes:

  • Uses unified_planning.shortcuts.ProblemOptimizer.
  • Returns None if no optimization is possible.

3. Save Optimized Problem

save-optimized-problem(optimized_problem, output_path)

Description: Writes the optimized problem to disk in standard PDDL format.

Parameters:

  • optimized_problem: A PDDL problem that has been optimized.
  • output_path (str): Output file path.

Example:

save_optimized_problem(optimized_problem, "optimized_task01.pddl")

Notes:

  • Uses unified_planning.io.PDDLWriter for output.
  • Outputs a text file with optimized specifications.

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.

skill-131 is a skill published in the GitHub repository legendtkl/agentic-skill-router (5 stars, last pushed 3mo ago), licensed MIT. It adds 21 tokens to every session and 715 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 2026-09-03.
