adapter-builder

adapter-builder is an agent for coding agents from Chemaclass/agnostic-ai. It costs 17 tokens per session (329 once invoked), scanned A, original, MIT.

An agent for adding support for a new AI command-line tool to agnostic-ai. An adapter is the code that translates the shared project format into a particular tool’s configuration format.

In plain words
What is it for?
It is for implementing and testing a new target in the Go project, including supported agents, skills, rules, or hooks when the target provides them.
Why use it?
It coordinates the code, registration, documentation, example configuration, tests, and changelog updates needed for a complete integration.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

adapter-builder 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 5d 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

You add a new AI CLI adapter to agnostic-ai end to end.

Steps:

  1. Ask the user (or read the linked issue) for: target name, official docs link, native config paths, supported spec kinds (agents, skills, rules, hooks).
  2. Create internal/adapters/<name>/<name>.go following the contract in the adapter-pattern rule. Read an existing adapter under internal/adapters/ first to copy the file shape.
  3. Register in internal/adapters/adapter.go.
  4. Add to default targets in internal/config/config.go and internal/cli/init.go.
  5. Update .gitignore if the target writes new generated paths at root.
  6. Update docs/user/targets.md capability matrix and per-target output section.
  7. Update README.md capability table.
  8. Update agnostic-ai.yaml example with the new target name and a comment.
  9. Add a unit test in internal/adapters/<name>/<name>_test.go.
  10. Run make build && make test.
  11. Add a [Unreleased] entry to CHANGELOG.md.

The required adapter shape (stateless struct, New(), Emit() signature, Capabilities declaration, shared-helper rules) lives in the adapter-pattern rule. Read it before step 2.

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.
