HOST INSTALL GUIDE / CODEX

Install marketing skills
for Codex.

Add the complete China marketing workflow library to a Codex project, or install only the skill needed for the current job. This guide separates the repository installer from Codex's official skill discovery paths so the result is easy to inspect and verify.

01 / INSPECT BEFORE INSTALLING

See every available module before changing the project.

The command below asks this repository's installer to list compatible skills. It is a repository distribution route, not a vendor-owned command. Review the source and stable slugs before choosing all ten modules or one skill.

PREVIEW / NO INSTALLREADY

02 / INSTALL THE PACKAGE

Run the installer from the target project directory.

Install the complete library when you need several connected workflows. For a smaller trial, open a skill detail page and use its --skill command.

03 / VERIFY OFFICIAL DISCOVERY PATHS

Confirm the files landed where the host looks.

Codex searches project-level .agents/skills directories from the current working directory up through the repository root. User-level skills belong in ~/.agents/skills; administrators can provision /etc/codex/skills.

04 / INVOKE AND CONFIRM

Prove the host can see the skill before using live work.

Use the host's manual invocation route, then ask for the skill name, expected inputs, and first safe step. Discovery is not the same as permission: review every tool or connector separately.

    $skill-name

05 / SAFE FIRST TEST

Use one synthetic or public marketing job.

Start with a narrow task that has known inputs and a reviewable output. The goal is to verify discovery, references, boundaries, and handoffs—not to hand the new method confidential work immediately.

SOURCE

Read SKILL.md and every linked reference or script.

INPUT

Use public or synthetic materials with no accounts, keys, or client documents.

OUTPUT

Compare the result with the skill's stated template and boundaries.

HUMAN

Keep a named owner for claims, approvals, commitments, and external actions.

TEST PROMPT / SYNTHETIC INPUTUse research-competitors for a synthetic China market scenario. Before researching, list the decision, minimum inputs, evidence categories, and human checkpoints. Do not use private data or make current market claims without sources.
06 / TROUBLESHOOT

Check scope, shape, refresh, then permissions.

  1. 01
    The skill is outside the project search path

    Move it into .agents/skills under the working directory or a parent through the repository root, or use ~/.agents/skills for user scope.

  2. 02
    The directory has an extra nesting level

    The expected shape is <skill-name>/SKILL.md. Preserve referenced files beside it without wrapping the skill in another directory.

  3. 03
    The skill is present but not listed

    Restart Codex, then use /skills and inspect the skill's name and description frontmatter.

  4. 04
    The skill starts but cannot complete the job

    Check the referenced files and required tools. A skill supplies a method; it does not automatically grant file, network, or connector permissions.

FAQ

Installation questions

01Can I install only one marketing skill?

Yes. Open a skill page and run the command containing --skill and its stable slug.

02Does installation give the skill access to private data?

No. Access depends on the host, enabled tools, connectors, and permissions. Review them independently.

03Should the skill live in the repository?

Use project scope when the team should review and version the method together. Use user scope only for a personally reviewed skill needed across projects.

04How do I update the library?

Review upstream changes first, rerun the installer or replace the directory, and repeat the discovery and safe-test checks.

RELATED / OTHER HOSTS

The method is portable; discovery is host-specific.
