OpenSDL: Skill for Claude Code

.agents/skills/add-adapter/SKILL.md

add-adapter is a skill for Claude Code, Codex from fl-sean03/OpenSDL. It costs 35 tokens per session (268 once invoked), scanned A, original, Apache-2.0.

A workflow for adding an OpenSDL adapter, which connects a capability such as an instrument, robot, computing service, or human task to a software system. It includes both a real transport and a simulator for testing.

In plain words
What is it for?
Use it to create a typed adapter, add a deterministic simulator, write conformance tests, and verify that the declared capability works in simulation.
Why use it?
It gives the adapter defined handling for health checks, startup and shutdown, time limits, retries, and failures before it is used with real equipment.

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents); mentions AGENTS.md.

This is fl-sean03/OpenSDL's own configuration. It tells Claude Code and Codex how to work on OpenSDL itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything OpenSDL configures →

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-adapter 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 2mo ago.

The scan reads SKILL.md. This mod also ships 1 executable file (run.sh), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Add an adapter

Inputs

  • adapter name
  • first capability identifier
  • destination directory, default adapters

Procedure

  1. Inspect the nearest AGENTS.md and the capability contract.
  2. Run .agents/skills/add-adapter/run.sh NAME CAPABILITY_ID [DESTINATION].
  3. Implement typed transport, health, lifecycle, timeout, retry, and failure behavior.
  4. Keep a deterministic simulator or mock beside the operational transport.
  5. Add conformance cases, package tests, and one runnable simulation fixture.
  6. Add the package to the workspace only when it belongs in this coordinated repository.
  7. Run the package tests, uv run --locked pytest -m conformance, and repository validation.

Completion

The adapter is discoverable by entry point, passes conformance, and executes its declared capability against simulation. Report the tested transport or equipment version without claiming untested hardware behavior.

Stop conditions

Stop if the semantic capability, equipment limits, safe failure behavior, or simulator contract is unclear. Do not connect physical equipment as part of scaffolding.

Files

What ships with it

1 file 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.
