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

phpstorm-prereview 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 2mo 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.

Prereview — development notes

PhpStorm plugin for local, PR-style code review: inline comments in the editor, written by the user or imported from AI agent runs (codex and claude CLIs reviewing the current branch against the default branch).

Build & run

  • ./gradlew build — compile + tests
  • ./gradlew runIde — sandboxed PhpStorm with the plugin
  • The Gradle wrapper defaults GRADLE_USER_HOME to ./.gradle-user-home (unless already set) to isolate plugin-SDK caches.
  • Releases are driven by GitHub releases: the tag vX.Y.Z becomes the plugin version; pluginVersion in gradle.properties is only a local fallback.

Architecture decisions

  • The core UI primitive is a component inlay card (a real Swing panel embedded in the editor via ComponentInlayAdapter), not a gutter-icon-plus-tool-window combo. The quality of the inline UX is the whole point of the plugin; prefer improving the card over adding secondary surfaces.
  • Comment display has two states: compact (range highlight + gutter marker) and expanded (the inlay card). The tool window is a fallback/overview, not the primary surface.
  • Anchoring is deliberately best-effort: file URL + offsets + line, plus a dedicated anchor line (card renders under the end of the selection) and a small context snippet. Anchors track document edits (ReviewCommentDocumentSyncService) and file renames/moves (ReviewCommentsVfsSyncService); imprecision after heavy refactors is accepted, don't over-engineer recovery.
  • Persistence is project-local via PersistentStateComponent (ReviewCommentsService is the source of truth). No remote sync by design.
  • Agent runs (AgentReviewService) execute the codex and claude CLIs in parallel through StructuredCliReviewRunner subclasses, with a JSON output schema. Each agent's comments replace that agent's previous comments only when its run succeeds. CLI binaries are auto-discovered in PATH and common install locations — no user configuration.

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.
