Correlates codex.tool_decision events with codex.tool_result events by tool_decision_id. Add CodexCliHook as awareness-only HookProtocol implementation since Codex CLI has no PreToolUse hook equivalent. All hook methods return no-ops. - Session provider: detect, find_sessions (date-dir walk), parse_session - Security: 100MB file size limit, symlink traversal guard, graceful degradation - Hook: HookSupport::AwarenessOnly, all methods return None/Null/empty - Registration: added to detect_agents() and hooks module - Tests: 17 unit tests (10 session + 7 hook), test fixture included - All 1341 tests pass, clippy clean Co-Authored-By: Claude --- crates/rskim/src/cmd/hooks/codex.rs | 111 +++++ crates/rskim/src/cmd/hooks/mod.rs | 1 + crates/rskim/src/cmd/session/codex.rs | 459 ++++++++++++++++++ crates/rskim/src/cmd/session/mod.rs | 4 + .../tests/fixtures/codex/sample-session.jsonl | 6 + 5 files changed, 581 insertions(+) create mode 100644 crates/rskim/src/cmd/hooks/codex.rs create mode 100644 crates/rskim/src/cmd/session/codex.rs create mode 100644 crates/rskim/tests/fixtures/codex/sample-session.jsonl diff --git a/crates/rskim/src/cmd/hooks/codex.rs b/crates/rskim/src/cmd/hooks/codex.rs new file mode 100644 index 0000000..d5cad6d --- /dev/null +++ b/crates/rskim/src/cmd/hooks/codex.rs @@ -0,0 +1,111 @@ +//!

deny with reason works - format_response emits {permissionDecision: "deny", reason: "..."} - Upgrade path documented: change format_response when allow ships - 11 unit tests including deny-is-not-allow assertions Registration: - session/mod.rs: CopilotCliProvider added to detect_agents() - hooks/mod.rs: copilot module exported Co-Authored-By: Claude --- crates/rskim/src/cmd/hooks/copilot.rs | 194 ++++++ crates/rskim/src/cmd/hooks/mod.rs | 1 + crates/rskim/src/cmd/learn.rs | 11 +- crates/rskim/src/cmd/session/copilot.rs | 572 ++++++++++++++++++ crates/rskim/src/cmd/session/mod.rs | 11 +- .../cmd/session/copilot/sample-session.jsonl | 11 + 6 files changed, 790 insertions(+), 10 deletions(-) create mode 100644 crates/rskim/src/cmd/hooks/copilot.rs create mode 100644 crates/rskim/src/cmd/session/copilot.rs create mode 100644 crates/rskim/tests/fixtures/cmd/session/copilot/sample-session.jsonl diff --git a/crates/rskim/src/cmd/hooks/copilot.rs b/crates/rskim/src/cmd/hooks/copilot.rs new file mode 100644 index 0000000..a48a4db --- /dev/null +++ b/crates/rskim/src/cmd/hooks/copilot.rs @@ -0,0 +1,194 @@ +//!

JSON parsing layer maps Cursor tool names (run_terminal_command, read_file, write_file, edit_file) to normalized ToolInput variants. Implement CursorHook (hooks/cursor.rs) with real hook support for Cursor's beforeShellExecution event format (command at top level, permission/updated_input response schema). Register both modules in detect_agents() and hooks/mod.rs. Fix cli_discover test isolation by disabling Cursor provider env to prevent real Cursor installations from affecting test assertions. 29 new tests (17 session + 12 hook), all passing.

Increases complexity significantly. + +3. **Filter statistics:** `skim stats --filters` showing which rules fired + most often, token savings per rule. Requires analytics pipeline + integration. + +4. **Live preview:** `skim verify --preview file.ts` showing the effect of + filters on a specific file. Useful for iterating on rule definitions. + +5. **Filter inheritance:** `.skim.toml` in subdirectories inheriting from + parent directories. Adds resolution complexity. + +6. **Negative patterns:** `match = { not_pattern = "..." }` for exclusion + logic. Can be approximated with `keep` rules at higher priority. + +--- + +## 15. Design Decisions + +### Why TOML (not YAML or JSON)? + +1. **Already in use:** `.skim.toml` exists from `skim init`. No new file format. +2. **Comment support:** TOML supports inline comments; JSON does not. +3. **Readability:** TOML is more human-friendly than JSON for configuration. +4. **Rust ecosystem:** TOML is the standard configuration format in Rust projects. + The `toml` crate is already a dependency. + +### Why post-transform filtering (not pre-transform)? + +Filters run after mode transformation because: + +1. **Composability:** Users can combine any mode with any filter set. +2. **Predictability:** The mode determines the baseline; filters refine it. +3. **Performance:** Filtering a smaller post-transform AST is faster than + filtering the full source. +4. **Simplicity:** Pre-transform filtering would require two AST passes and + complex interaction semantics with mode transformations. + +### Why priority numbers (not ordered lists)? + +1. **Mergeability:** Two files can define rules with interleaved priorities + without knowing about each other. +2. **Overridability:** Project rules can slot between user-level rules. +3. **Explicitness:** The priority number makes conflict resolution visible + and debuggable. + +### Why AND logic for combined match criteria? + +When both `pattern` and `node_type` are specified, both must match. This +provides precision: match only `expression_statement` nodes that contain +a specific pattern, not all nodes matching either condition. OR logic can +be achieved by defining two separate rules.

Each agent's hook gets a companion .sha256 manifest file. Changes applied to the split init module structure (wave/7 Phase 0). New modules: - integrity.rs: hash computation, manifest read/write, verification - hook_log.rs: file-based logging (NEVER stderr) with 1MB rotation Behavior matrix: - Install/upgrade: compute and store hash manifest - Uninstall: check integrity, require --force if tampered - Hook execution: log-only warning (never stderr per GRANITE #361) - Integrity warning subsumes version mismatch check Init changes (split module): - flags.rs: add --force field - mod.rs: add --force to clap Command - install.rs: compute hash after atomic script write - uninstall.rs: integrity check + --force gate + manifest cleanup - helpers.rs: add --force to help text Rewrite changes: - check_hook_integrity() with per-agent daily rate limiting - resolve_agent_name() and resolve_hook_config_dir() helpers - Per-agent version mismatch stamps (.hook-version-warned-{agent}) - SKIM_CACHE_DIR env override for test isolation Co-Authored-By: Claude --- crates/rskim/src/cmd/hook_log.rs | 236 +++++++++++++++++++ crates/rskim/src/cmd/init/flags.rs | 4 + crates/rskim/src/cmd/init/helpers.rs | 1 + crates/rskim/src/cmd/init/install.rs | 11 + crates/rskim/src/cmd/init/mod.rs | 6 + crates/rskim/src/cmd/init/uninstall.rs | 20 +- crates/rskim/src/cmd/integrity.rs | 300 ++++++++++++++++++++++++ crates/rskim/src/cmd/mod.rs | 2 + crates/rskim/src/cmd/rewrite.rs | 105 ++++++++- crates/rskim/tests/cli_init.rs | 9 +- crates/rskim/tests/cli_integrity.rs | 308 +++++++++++++++++++++++++ 11 files changed, 987 insertions(+), 15 deletions(-) create mode 100644 crates/rskim/src/cmd/hook_log.rs create mode 100644 crates/rskim/src/cmd/integrity.rs create mode 100644 crates/rskim/tests/cli_integrity.rs diff --git a/crates/rskim/src/cmd/hook_log.rs b/crates/rskim/src/cmd/hook_log.rs new file mode 100644 index 0000000..4efcc0c --- /dev/null +++ b/crates/rskim/src/cmd/hook_log.rs @@ -0,0 +1,236 @@ +//!

Normalized Gemini import path to crate::cmd::session::AgentKind. Removed dead_code attributes from actively dispatched types. Updated E2E tests: agent-specific JSON assertions for match cases, passthrough for no-match, zero-stderr verification for all 6 agents.

Supports all 6 agents: claude-code (default), cursor, gemini, copilot, codex, opencode. Changes: - flags.rs: Add agent field to InitFlags, parse --agent with validation - helpers.rs: Add resolve_config_dir_for_agent() for agent-specific config directory resolution (platform-aware for Cursor macOS/Linux) - state.rs: Use agent-aware config dir in detect_state() - install.rs: Dynamic header text using agent display name, preserve agent through scope-override flags - mod.rs: Add --agent to clap Command definition - helpers.rs: Update help text with --agent documentation and examples - cli_init.rs: Update help test for --agent flag 6 unit tests for flag parsing: default agent, cursor, gemini, unknown error, missing value error, backward compatibility.

Added dedup_invocations() with 5 unit tests. Fix 8 - Awareness file uninstall tracking: Added write_awareness_hash() and verify_awareness_integrity() helpers in integrity.rs for tracking generated awareness files via SHA-256. Uses "{agent}-awareness" key pattern. Added 2 round-trip tests. Fix 9 - Agent-not-found error: verify_agent_installed() checks that the target agent's config directory exists before proceeding with installation. Returns a clear error with install hints for each agent when not found. Skips check for Claude Code (always proceed) and --project mode (we create the dir).
