Cross Agent Skill Sync

Use when discovering, verifying, or sharing SKILL.md based skills across local Hermes, Codex, OpenClaw, Gemini, OpenCode, Claude-adjacent, and generic agent skill roots without overwriting existing skills or leaking private paths.

File contents

Cross-Agent Skill Sync

Use this skill when the user wants the same skill layer to be visible to multiple local agents, including Hermes, Codex, OpenClaw-style workspaces, Gemini CLI, OpenCode, Claude-adjacent setups, and generic SKILL.md consumers.

The helper is additive and dry-run-first:

node skills/software-development/cross-agent-skill-sync/scripts/cross_agent_skill_sync.mjs --target all

Operating Rules

Never overwrite an existing skill unless the user explicitly asks for a destructive replacement workflow.
Prefer --strategy symlink for local same-machine sharing; use --strategy copy for portable snapshots or remote machines.
Treat paths, prompts, profiles, tokens, memory, browser state, and agent logs as private. The report redacts $HOME by default.
Use --execute only after the dry-run plan looks correct.
Use --require-skill <name> for must-have skills, especially bridge skills such as codex-computer-use-eu-activate.
For Claude Code, project skills only into a configured local skill directory or emit docs/indexes. Do not assume Claude consumes arbitrary SKILL.md folders unless the local setup has that bridge.

Common Local Sync

Plan a sync of the repository skills into all known local agent roots:

node skills/software-development/cross-agent-skill-sync/scripts/cross_agent_skill_sync.mjs \
  --target all \
  --require-skill ai-research-browser \
  --require-skill oracle-ai-research-e2e

Add an external local skill, such as a Codex Computer Use activation bridge, without committing its private path:

node skills/software-development/cross-agent-skill-sync/scripts/cross_agent_skill_sync.mjs \
  --target hermes \
  --include-skill /path/to/codex-computer-use-eu-activate/skill/codex-computer-use-eu-activate \
  --require-skill codex-computer-use-eu-activate

Execute after review:

node skills/software-development/cross-agent-skill-sync/scripts/cross_agent_skill_sync.mjs \
  --target all \
  --strategy symlink \
  --execute \
  --out /tmp/cross-agent-skill-sync-report.json

Verification

Run the deterministic tests:

node --test skills/software-development/cross-agent-skill-sync/tests/cross_agent_skill_sync.test.mjs

Then run the repository-wide public safety audit:

scripts/audit-public-safety.sh

Status Meanings

install: destination is missing and will be created when --execute is set.
installed: destination was created in this run.
exists: destination already exists and was left untouched.
conflict: destination exists with different content or an unexpected shape; manual review needed.
missing-required-skill: a required skill was not found in the selected sources.

Good Boundaries

This skill shares instructions and helper files. It does not share browser cookies, provider sessions, private memories, shell histories, token files, or agent transcripts.
