api-coverage

A set of project rules for keeping a record of which API tools are covered, planned, or excluded. An API is the interface that software exposes for other software to use.

In plain words
What is it for?
Use it when adding, renaming, or removing MCP tools, changing authentication or installation, or recording behavior changes and feedback.
Why use it?
It prevents tool changes, research notes, tests, documentation, and design decisions from falling out of sync.

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

api-coverage 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 yesterday.

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

API coverage tracking

When adding, renaming, or removing MCP tools:

  1. Update .cursor/research/proxmox-api-coverage.md status (done/planned/excluded).
  2. If closing or changing a roadmap item, update .cursor/research/next-expansion.md.
  3. Note non-obvious API quirks in .cursor/research/changelog-notes.md.
  4. Record design choices in .cursor/research/decisions.md when changing patterns.
  5. Keep tests/expected_tools.py in sync with server.py _setup_tools().
  6. Follow keep-docs-aligned.mdc for README / definitions / SETUP when auth or install changes.
  7. Auth/privsep quirks belong in changelog-notes.md + decisions.md (see D8) and .cursor/rules/proxmox-auth.mdc.
  8. Append a row to .cursor/research/revisions.md for agent-visible behavior changes.
  9. If the change came from lab/agent feedback, append to .cursor/research/agent-feedback-log.md (symptoms → root cause → fix → out of scope).
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.
