Install Reasoning

Pick your agent. Every command is ready to paste.

$npx skills add jeremylongshore/tons-of-skills-marketplace --skill reasoning

The open skills CLI detects your agents (Claude Code, Cursor, Codex and 70+ more) and installs to the right folder. Add -g to install globally.

01

Install it

Run the command above, or upload the folder in Claude.

02

Ask naturally

Describe the task. Your agent loads reasoning when the request matches its description.

03

Name it if needed

If it does not trigger, say “use the reasoning skill”. In Codex, type $reasoning.

Reasoning Harness

When this skill triggers, call the reasoning tool from the ejentum MCP server. Pass a 1-2 sentence framing of WHAT you are reasoning about as the query argument. Be specific about the task, not what tool you want.

Good query: diagnose why a microservice returns 503s under load Bad query: help me think

The tool returns a structured scaffold containing:

  • [NEGATIVE GATE]: failure pattern to avoid
  • [PROCEDURE]: steps to follow
  • [REASONING TOPOLOGY]: decision flow with gates and traps
  • [TARGET PATTERN]: correct shape your reasoning should take
  • [FALSIFICATION TEST]: self-check criterion
  • Amplify: signals to engage
  • Suppress: failure modes to block

Absorb the scaffold internally and shape your response with it. The bracketed fields are instructions, not content to display. Do NOT echo the bracket labels, do NOT name the topology, do NOT meta-comment on calling the tool. The user-facing reply is naturally phrased and shaped by the injection.

If the API is unreachable or returns an error, proceed with native reasoning. The scaffold enhances; it is not a hard dependency.

Latency cost: ~1 second. Benefit: reasoning quality the model cannot reliably reproduce on its own for non-trivial tasks.

Tips for Reasoning

  • • Start a fresh session after installing so your agent picks up the new skill.
  • • It is part of a pack with 30 skills. Install only the ones you need with --skill to keep triggers precise.
  • • If two skills overlap, mention the one you want by name.
