external-references is a skill for Claude Code, Codex from i9wa4/dotfiles. It costs 69 tokens per session (461 once invoked), scanned A, original, MIT.

Routing guidance for consulting inactive reference packs about services such as AWS, Azure, Google Cloud, Terraform, Databricks, dbt, and Obsidian.

In plain words
What is it for?
Use it to inspect local reference files, look up provider syntax, answer promotion questions, and decide whether a reference pack should become active.
Why use it?
It helps find provider-specific instructions without loading broad collections of material into the active setup or enabling them by accident.

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

external-references 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 1mo 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.

What it actually says

External References

Dormant provider-pack references live under ~/.local/share/skills. Direct reads from ~/.local/share/skills/<skill-name>/* need no promotion; promote only when the user asks to make a pack active/invokable.

1. Workflow

  1. Read matching bodies under ~/.local/share/skills/<skill-name>.
  2. Enumerate available reference skill names from ~/.local/share/skills/.i9wa4-agent-skills-reference-only.manifest when the generated name is unclear.
  3. Use nix/home-manager/agents/shared/agent-skills.nix referenceOnlySources only when the generated tree is missing or source verification is needed.
  4. Prefer local owner skills for guardrails: data-platform, programming, or dotfiles.
  5. Promote only on an explicit active-provider-pack request.

2. Dormant Packs

cloudflare-skills, databricks-official, dbt, azure, google, aws, hashicorp-terraform, googleworkspace-cli, and streamlit. Use active security-audit for Cloudflare security audits.

3. Direct Read Example

For Terraform, read ~/.local/share/skills/terraform-style-guide/SKILL.md and use the manifest for related Terraform names. hashicorp-terraform is an inventory group, not necessarily a directory.

4. Promotion Rules

For Claude, add a source through i9wa4.agentSkills.extraSources or an explicit repo decision. For Codex, also update codexMinimalSourceNames and codexMinimalAllowlist.

Files

What ships with it

4 files 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.
