add-resource

add-resource is a skill for Claude Code, Codex from plainlang/plain-forge. It costs 51 tokens per session (2,204 once invoked), scanned A, original, MIT.

A way to link an external file into a plain specification. The linked file can be a JSON schema, API description, data file, or similar supporting resource.

In plain words
What is it for?
Use it to reference schemas, API specifications, transformation files, or other project resources from a specification.
Why use it?
It keeps large or reusable supporting details outside the specification while still making them available during rendering and code generation.

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

add-resource 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 20d 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.

How it starts

The opening of the file, as written. The whole thing — 109 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Add Resource

Always use the skill load-plain-reference to retrieve the ***plain syntax rules — but only if you haven't done so yet.

Linked resources are external files referenced from within a .plain spec using markdown link syntax. The file contents are passed to the renderer alongside the spec, providing additional context for code generation.

Workflow

  1. Identify or create the resource file. Keep it inside the project — the resources/ directory is the conventional home; it does not have to sit next to the .plain file.
  2. Add the markdown link at the appropriate place in the spec.
  3. Verify the file path is relative to the .plain file location.
  4. Read the file back to confirm correct link syntax and path.

Format

Use standard markdown link syntax inside any spec section:

***definitions***
- :AuthData: is the authentication data structure.
  - Its format is defined in the [auth schema](resources/auth_schema.json).

***implementation reqs***
- When transforming :BackupData:, use the JOLT transform.
  - The transform is defined in [backup_transform.jolt](resources/backup_transform.jolt).

***functional specs***

- An API conforming to the [API specification](resources/api_spec.yaml) is exposed.

Path Rules

  • Paths are resolved against the directory that contains the .plain file passed to the renderer, not the directory where the renderer is run.
  • This includes links inside imported and required modules — they resolve against that same directory, not against the directory the imported module itself lives in.
  • A path that does not resolve there is then looked up in the template-dir directory (if configured), and last in the renderer's built-in template library.
  • Relative paths may traverse into parent directories — [resource](../../resources/resource.md) is valid — as long as they resolve to a real text file on disk.
  • No external URLs — only local file references.
  • No folder paths — the target must be a file, not a directory.
  • Only text-based files are supported.

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.

add-resource is a skill published in the GitHub repository plainlang/plain-forge (79 stars, last pushed yesterday), licensed MIT. It adds 51 tokens to every session and 2,204 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-30.
