Example: with prompts at indexes 1, 2, 3 and a `rewind_marker` with `target_prompt_index: 2`, this library deletes prompt 3 only, while upstream replay deletes prompts 2 and 3.

The library reads: - -- Core/runtime: `CLAUDE_PROJECT_DIR`, `CLAUDE_ENV_FILE`, `CLAUDE_CODE_DEBUG_LOG_LEVEL`, `CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS`, `CLAUDE_CODE_SYNC_PLUGIN_INSTALL`, `CLAUDE_HOOK_DEBUG`, `CLAUDE_HOOK_TIMEOUT` -- Protection and command policy: `CLAUDE_HOOK_PROTECTED_FILES`, `CLAUDE_HOOK_DANGEROUS_COMMANDS`, `CLAUDE_HOOK_STRICT_PROTECTION`, `CLAUDE_HOOK_EXTRA_PROTECTED`, `CLAUDE_HOOK_READ_ONLY`, `CLAUDE_HOOK_AUTO_APPROVE_READS` -- Formatting and post-tool checks: `CLAUDE_HOOK_AUTO_FORMAT`, `CLAUDE_HOOK_DISABLE_PRETTIER`, `CLAUDE_HOOK_DISABLE_ESLINT`, `CLAUDE_HOOK_FORMAT_TIMEOUT`, `CLAUDE_HOOK_FAIL_ON_FORMAT_ERROR`, `CLAUDE_HOOK_STRICT_POST_VALIDATION` -- TypeScript validation: `CLAUDE_HOOK_TS_FULL_CHECK`, `CLAUDE_HOOK_TS_BLOCK_ON_ERROR`, `CLAUDE_HOOK_TS_TIMEOUT`, `CLAUDE_HOOK_TS_STRICT_FILES`, `CLAUDE_HOOK_CONVEX_VALIDATION` -- Notifications: `CLAUDE_HOOK_DESKTOP_NOTIFICATIONS`, `CLAUDE_HOOK_CONSOLE_NOTIFICATIONS`, `CLAUDE_HOOK_NOTIFICATIONS_IN_CI`, `CLAUDE_HOOK_NOTIFICATION_COMMAND`, `CLAUDE_HOOK_SLACK_WEBHOOK`, `CLAUDE_HOOK_EMAIL_TO`, `CLAUDE_HOOK_EMAIL_FROM`, `CLAUDE_HOOK_SMTP_SERVER` -- Session context/end: `CLAUDE_HOOK_SESSION_GIT`, `CLAUDE_HOOK_SESSION_DEPS`, `CLAUDE_HOOK_SESSION_CHANGES`, `CLAUDE_HOOK_SESSION_DEV_STATUS`, `CLAUDE_HOOK_SESSION_MAX_COMMITS`, `CLAUDE_HOOK_SESSION_MAX_CHANGES`, `CLAUDE_HOOK_CONTEXT_FILES`, `CLAUDE_HOOK_CLEANUP_TEMP`, `CLAUDE_HOOK_SAVE_STATS`, `CLAUDE_HOOK_GENERATE_SUMMARY`, `CLAUDE_HOOK_ARCHIVE_TRANSCRIPT`, `CLAUDE_HOOK_SEND_NOTIFICATIONS`, `CLAUDE_HOOK_MAX_TEMP_AGE` -- Prompt/stop/subagent/pre-compact: `CLAUDE_HOOK_CHECK_SECRETS`, `CLAUDE_HOOK_ADD_CONTEXT`, `CLAUDE_HOOK_VALIDATE_STRUCTURE`, `CLAUDE_HOOK_CHECK_INJECTION`, `CLAUDE_HOOK_MAX_PROMPT_LENGTH`, `CLAUDE_HOOK_BLOCK_INJECTION`, `CLAUDE_HOOK_CHECK_TASKS`, `CLAUDE_HOOK_CHECK_GIT`, `CLAUDE_HOOK_CHECK_TESTS`, `CLAUDE_HOOK_VALIDATE_SUBAGENT`, `CLAUDE_HOOK_CHECK_SUBAGENT_ERRORS`, `CLAUDE_HOOK_LOG_SUBAGENT_METRICS`, `CLAUDE_HOOK_SAVE_CONTEXT`, `CLAUDE_HOOK_EXTRACT_DECISIONS`, `CLAUDE_HOOK_CREATE_BACKUP`, `CLAUDE_HOOK_MAX_CONTEXT_SIZE` - -Processing CLIs have a separate env surface that is not loaded through `getConfig()`, including `CLAUDE_TAIL_MARKER_ROOTS` for `claude-session-tail --marker-dir`. Keep hook env-var docs and processing CLI docs separate. Library consumers of the tail APIs should pass the per-call `allowedMarkerRoots` option instead of relying on that env var. - -Set `CLAUDE_HOOK_DEBUG=true` or `CLAUDE_CODE_DEBUG_LOG_LEVEL=verbose` for verbose library logging. `CLAUDE_HOOK_TIMEOUT` defaults this library's runner to 60 seconds; Claude Code settings handlers instead default to 600 seconds for command/HTTP/MCP, 30 for prompt, and 60 for agent, with 30-second UserPromptSubmit and 10-second MessageDisplay overrides. `CLAUDE_CODE_SESSIONEND_HOOKS_TIMEOUT_MS` defaults to 1500 ms and is capped at 60000 ms. - -## Code review (Greptile) - -This is a public OSS repo. **Greptile is available here permanently** (OSS free forever) for PR bot review and local CLI review. Prefer it as the primary automated reviewer for this repository. - -**Local (pre-push):** Commit first, then review committed work against the base branch. Agents should use structured output. - -```bash -greptile whoami # must be signed in (check text; exit 0 even when signed out) -greptile review -b main --json # or omit -b for the repo default base -greptile review status --json # whether HEAD already has a completed review -``` - -- Findings still exit `0`; non-zero means the review did not finish. -- Triage `securityIssue: true`, then `P0` / `P1` / `P2`. Aim for confidence `5` with zero comments when polishing a branch (`greploop` skill if iterating). -- PR bot comments are fetched with `gh` (`gh api repos/.../pulls//comments`), not with the Greptile CLI. - -**Do not** treat CodeRabbit (or other review bots) as the source of truth on this repo when Greptile is configured. - -## Public Repository Hygiene - -Scratch planning and agent-runtime files stay out of the public tree: free-floating context docs such as `prometheus-implementation-context.md`, `.omo/notepads/*`, `.omo/senpi-task/`, `.omo/start-work/`, `.omo/run-continuation/`, `boulder.json`, repo-root `plans/`, and `.grok/`. Persistent product guidance belongs in user-facing docs or ADRs. - -`.omo/` is the live scratchpad. Track at most one live plan under `.omo/plans/` (unchecked until the increment is accepted) and `.omo/rules/` when this repo injects rules. Archive a finished plan to `.plans/NN-slug.md`. Write learnings on that file; promote to `docs/` only when the public contract changes. Evidence is one dated packet force-added after a real increment, or omitted. Before merge or a fresh re-run: archive or restore the plan, then drop runtime and leftover drafts from the index. Inspect unfamiliar `.omo/` paths before deleting them. Workstation copy: `~/.agents/AGENTS.md` (skill `omo-workspace-state`). - -## Working discipline - -- **Unslop.** Always on. Read `~/.agents/skills/unslop/SKILL.md` and apply it to every reply, commit message, PR body, and new doc. Existing context files get a later dedicated pass. -- **OmO workspace state.** Follow the hygiene rules above. `.omo/plans/` is live only; `.plans/` is the archive. -- **Commits are recovery boundaries, not workflow gates.** An execution plan's explicit commit strategy counts as authorization on its work branch; otherwise ask before committing. Prefer a commit after a coherent logical unit and its relevant quality gate, but never force one per todo, create empty commits, absorb unrelated or pre-existing changes, or commit from an unsafe dirty baseline. When no clean boundary exists, preserve and account for the state in the tracked plan/draft rather than discarding it; commit at the next safe boundary. Push only on the user's explicit request; never use `git stash`. -- **GitHub transport on this workstation is SSH.** Use `git@github.com:/.git` remotes and confirm `gh auth status` reports `Git operations protocol: ssh` before a push. Do not switch remotes to HTTPS, replace SSH with token transport, or edit credential configuration unless the user explicitly requests that action. -- **Unreleased OmO installs are user-controlled.** The user switches the official `~/dev-admin/oh-my-openagent` clone to `dev` when needed and owns `~/.omo/omo.jsonc`. Agents may inspect and report that state, but must not checkout, pull, build, globally install, or edit the OmO configuration unless the user explicitly requests that action. - -## Comment Style - -- Preserve API-contract JSDoc on every exported type, interface, function, class, and method. Keep parameter, return, thrown-error, and behavior notes that public consumers rely on. -- Strip temporal, AI-workflow, migration, provenance, and marketing phrasing from comments. Avoid examples such as `Following ... pattern`, `incremental`, `Phase`, `recently`, `parent project`, `ported from`, `moved to`, `will`, `currently`, `now`, `new`, `modern`, `legacy`, `comprehensive`, and `designed for`. -- Treat filler wording as noise. Avoid `automatically` when it adds no technical detail, and avoid `supports` when the code, type, or API name already makes that clear. -- Keep comments that explain regression rationale, compatibility constraints, security-sensitive behavior, invariants, or non-obvious edge cases. -- Avoid heavy visual banners such as `// =====`, `// ----`, or long dashed separator lines. Prefer a single blank line between logical blocks. - -## Compatibility Notes - -`PermissionRequest` uses nested `hookSpecificOutput.decision` with `behavior: "allow" | "deny"` and the six documented permission-update variants. Stop and SubagentStop have separate block and non-error additional-context modes; block output requires a reason. Notification accepts only universal output. StopFailure is side-effect-only. The old top-level PermissionRequest allow/deny style should not be used. diff --git a/CLAUDE.md b/CLAUDE.md new file mode 120000 index 0000000..47dc3e3 --- /dev/null +++ b/CLAUDE.md @@ -0,0 +1 @@ +AGENTS.md \ No newline at end of file diff --git a/docs/README.md b/docs/README.md index 79aa59e..bf1e079 100644 --- a/docs/README.md +++ b/docs/README.md @@ -21,6 +21,7 @@ | [Validators](reference/validators.md) | Tool-input validators, type guards, content validators, config validators | | [Types](reference/types.md) | Full type catalogue — inputs, outputs, tools, config | | [Environment Variables](reference/environment-variables.md) | Every `CLAUDE_HOOK_*` variable with type, default, and description | +| [Grok Adapter](reference/grok-adapter.md) | Grok Build envelopes, settings, and session processing (attach-only) | ## Architecture & Internal
