appicon AGENTS.md

Project instructions for appicon, a command-line and MCP tool that resolves desktop and brand icons to local file paths. A cache stores previously resolved results for reuse.

In plain words
What is it for?
Use them when developing or changing appicon’s CLI, MCP wrapper, providers, cache, path handling, documentation, or tests.
Why use it?
They set rules for safe caching, downloads, credentials, archive handling, fallbacks, and optional daemon use, reducing security and reliability mistakes.

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

appicon AGENTS.md 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

Agent notes

  • Keep resolution cache-first. A warm cache must not contact a remote provider, and tests must use fixtures or httptest, never live services.
  • Consumers receive local paths from the CLI or MCP server. Do not move provider URLs or download logic into consumer repositories, and keep MCP as a thin wrapper over the shared resolver.
  • A resolve miss (exit 1) is supported behavior. Consumers must retain their fallback glyph and must not require appicon to start.
  • Remote hosts stay allowlisted. BYOK configuration stores only environment variable names (token_env/secret_env), never credentials; missing credentials skip the stage and appear as stage(auth) in explanations.
  • Treat pack archives, indexes, subdirectories, and install destinations as hostile input. Preserve path containment, extraction limits, and safe wipe boundaries.
  • Prefer user overrides for long-tail remaps instead of speculative built-in aliases. Do not vendor the full SVGL catalog.
  • The daemon is optional and unsupported on Windows; all CLI operations must continue to work in-process.
  • Start documentation changes at docs/README.md, and keep the linked contract/schema pages synchronized.
  • Test new behavior and edge cases, then run make check-fast; run make check before handing off or committing release-bound work.

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.
