--- summary: "CLI reference for `openclaw path` (inspect and edit workspace files via the `oc://` addressing scheme)" read_when: - You want to read or write a leaf inside a workspace file from the terminal - You're scripting against workspace state and want a stable, kind-agnostic addressing scheme - You're debugging a `oc://` path (validate the syntax, see what it resolves to) title: "Path" --- # `openclaw path` Plugin-provided shell access to the `oc://` addressing substrate: one kind-dispatched path scheme for inspecting and editing addressable workspace files (markdown, jsonc, jsonl). Self-hosters, plugin authors, and editor extensions use it to read, find, or update a narrow location without hand-rolling per-file parsers. The CLI mirrors the substrate's public verbs: - `resolve` is concrete and single-match. - `find` is the multi-match verb for wildcards, unions, predicates, and positional expansion. - `set` only accepts concrete paths or insertion markers; wildcard patterns are rejected before writing. `path` is provided by the bundled optional `oc-path` plugin. Enable it before first use: ```bash openclaw plugins enable oc-path ``` ## Why use it OpenClaw state is spread across human-edited markdown, commented JSONC config, and append-only JSONL logs. Shell scripts, hooks, and agents often need one small value from those files: a frontmatter key, a plugin setting, a log record field, or a bullet item under a named section. `openclaw path` gives those callers a stable address instead of a one-off grep, regex, or parser for each file kind. The same `oc://` path can be validated, resolved, searched, dry-run, and written from the terminal, which makes narrow automation easier to review and safer to replay. It is especially useful when you want to update one leaf while preserving the rest of the file's comments, line endings, and surrounding formatting. Use it when the thing you want has a logical address, but the physical file shape varies: - A hook wants to read one setting from commented JSONC without losing comments when it writes the value back. - A maintenance script wants to find every matching event field in a JSONL log without loading the whole log into a custom parser. - An editor extension wants to jump to a markdown section or bullet item by slug, then render the exact line it resolved to. - An agent wants to dry-run a tiny workspace edit before applying it, with the changed bytes visible in review. You probably do not need `openclaw path` for ordinary whole-file edits, rich config migrations, or memory-specific writes. Those should use the owner command or plugin. `path` is for small, addressable file operations where a repeatable terminal command is clearer than another bespoke parser. ## How it is used Read one value from a human-edited config file: ```bash openclaw path resolve 'oc://config.jsonc/plugins/github/enabled' ``` Preview a write without touching disk: ```bash openclaw path set 'oc://config.jsonc/plugins/github/enabled' 'true' --dry-run ``` Find matching records in an append-only JSONL log: ```bash openclaw path find 'oc://session.jsonl/[event=tool_call]/name' ``` Address an instruction in markdown by section and item instead of by line number: ```bash openclaw path resolve 'oc://AGENTS.md/runtime-safety/openclaw-gateway' ``` Validate a path in CI or a preflight script before the script reads or writes: ```bash openclaw path validate 'oc://AGENTS.md/tools/$last/risk' ``` Those commands are meant to be copyable into shell scripts. Use `--json` when a caller needs structured output and `--human` when a person is inspecting the result. ## How it works `openclaw path` does four things: 1. Parses the `oc://` address into slots: file, section, item, field, and optional session. 2. Chooses the file-kind adapter from the target extension (`.md`, `.jsonc`, `.jsonl`, and related aliases). 3. Resolves the slots against that file kind's AST: markdown headings/items, JSONC object keys/array indexes, or JSONL line records. 4. For `set`, emits edited bytes through the same adapter so the untouched parts of the file keep their comments, line endings, and nearby formatting where the kind supports it. `resolve` and `set` require one concrete target. `find` is the exploratory verb: it expands wildcards, unions, predicates, and ordinals into the concrete matches you can inspect before choosing one to write. ## Subcommands | Subcommand | Purpose | | ----------------------- | ---------------------------------------------------------------------------- | | `resolve ` | Print the concrete match at the path (or "not found"). | | `find ` | Enumerate matches for a wildcard / union / predicate path. | | `set ` | Write a leaf or insertion target at a concrete path. Supports `--dry-run`. | | `validate ` | Parse-only; print structural breakdown (file / section / item / field). | | `emit ` | Round-trip a file through `parseXxx` + `emitXxx` (byte-fidelity diagnostic). | ## Global flags | Flag | Purpose | | --------------- | ------------------------------------------------------------------------ | | `--cwd ` | Resolve the file slot against this directory (default: `process.cwd()`). | | `--file ` | Override the file slot's resolved path (absolute access). | | `--json` | Force JSON output (default when stdout is not a TTY). | | `--human` | Force human output (default when stdout is a TTY). | | `--dry-run` | (only on `set`) print the bytes that would be written without writing. | ## `oc://` syntax ``` oc://FILE/SECTION/ITEM/FIELD?session=SCOPE ``` Slot rules: `field` requires `item`, and `item` requires `section`. Across all four slots: - **Quoted segments** — `"a/b.c"` survives `/` and `.` separators. Content is byte-literal; `"` and `\` are not allowed inside quotes. The file slot is also quote-aware: `oc://"skills/email-drafter"/Tools/$last` treats `skills/email-drafter` as a single file path. - **Predicates** — `[k=v]`, `[k!=v]`, `[kv]`, `[k>=v]`. Numeric ops require both sides to coerce to finite numbers. - **Unions** — `{a,b,c}` matches any of the alternatives. - **Wildcards** — `*` (single sub-segment) and `**` (zero-or-more, recursive). `find` accepts these; `resolve` and `set` reject them as ambiguous. - **Positional** — `$last` resolves to the last index / last-declared key. - **Ordinal** — `#N` for Nth match by document order. - **Insertion markers** — `+`, `+key`, `+nnn` for keyed / indexed insertion (use with `set`). - **Session scope** — `?session=cron-daily` etc. Orthogonal to slot nesting. Session values are raw, not percent-decoded; they may not contain control characters or reserved query delimiters (`?`, `&`, `%`). Reserved characters (`?`, `&`, `%`) outside quoted, predicate, or union segments are rejected. Control characters (U+0000-U+001F, U+007F) are rejected anywhere, including the `session` query value. `formatOcPath(parseOcPath(path)) === path` is guaranteed for canonical paths. Non-canonical query parameters are ignored except for the first non-empty `session=` value. ## Addressing by file kind | Kind | Addressing model | | ---------- | ----------------------------------------------------------------------------------------- | | Markdown | H2 sections by slug, bullet items by slug or `#N`, frontmatter via `[frontmatter]`. | | JSONC/JSON | Object keys and array indexes; dots split nested sub-segments unless quoted. | | JSONL | Top-level line addresses (`L1`, `L2`, `$last`), then JSONC-style descent inside the line. | `resolve` returns a structured match: `root`, `node`, `leaf`, or `insertion-point`, with a 1-based line number. Leaf values are surfaced as text plus a `leafType` so plugin authors can render previews without depending on the per-kind AST shape. ## Mutation contract `set` writes one concrete target: - Markdown frontmatter values and `- key: value` item fields are string leaves. Markdown insertions append sections, frontmatter keys, or section items and render a canonical markdown shape for the changed file. - JSONC leaf writes coerce the string value to the existing leaf type (`string`, finite `number`, `true`/`false`, or `null`). JSONC object and array insertions parse `` as JSON and use the `jsonc-parser` edit path for ordinary leaf writes, preserving comments and nearby formatting. - JSONL leaf writes coerce like JSONC inside a line. Whole-line replacement and append parse `` as JSON. Rendered JSONL preserves the file's dominant LF/CRLF line-ending convention. Use `--dry-run` before user-visible writes when the exact bytes matter. The substrate preserves byte-identical output for parse/emit round-trips, but a mutation can canonicalize the edited region or file depending on kind. ## Examples ```bash # Validate a path (no filesystem access) openclaw path validate 'oc://AGENTS.md/Tools/$last/risk' # Read a leaf openclaw path resolve 'oc://gateway.jsonc/version' # Wildcard search openclaw path find 'oc://session.jsonl/*/event' --file ./logs/session.jsonl # Dry-run a write openclaw path set 'oc://gateway.jsonc/version' '2.0' --dry-run # Apply the write openclaw path set 'oc://gateway.jsonc/version' '2.0' # Byte-fidelity round-trip (diagnostic) openclaw path emit ./AGENTS.md ``` More grammar examples: ```bash # Quote keys containing / or . openclaw path resolve 'oc://config.jsonc/agents.defaults.models/"anthropic/claude-opus-4-7"/alias' # Predicate search over JSONC children openclaw path find 'oc://config.jsonc/plugins/[enabled=true]/id' # Insert into a JSONC array openclaw path set 'oc://config.jsonc/items/+1' '{"id":"new","enabled":true}' --dry-run # Insert a JSONC object key openclaw path set 'oc://config.jsonc/plugins/+github' '{"enabled":true}' --dry-run # Append a JSONL event openclaw path set 'oc://session.jsonl/+' '{"event":"checkpoint","ok":true}' --file ./logs/session.jsonl # Resolve the last JSONL value line openclaw path resolve 'oc://session.jsonl/$last/event' --file ./logs/session.jsonl # Address markdown frontmatter openclaw path resolve 'oc://AGENTS.md/[frontmatter]/name' # Insert markdown frontmatter openclaw path set 'oc://AGENTS.md/[frontmatter]/+description' 'Agent instructions' --dry-run # Find markdown item fields openclaw path find 'oc://SKILL.md/Tools/*/send_email' # Validate a session-scoped path openclaw path validate 'oc://AGENTS.md/Tools/$last/risk?session=cron-daily' ``` ## Recipes by file kind The same five verbs work across kinds; the addressing scheme dispatches on the file extension. The examples below use the fixtures from the PR description. ### Markdown ```text --- name: drafter description: email drafting agent tier: core --- ## Tools - gh: GitHub CLI - curl: HTTP client - send_email: enabled ``` ```bash $ openclaw path resolve 'oc://x.md/[frontmatter]/tier' --file frontmatter.md --human leaf @ L4: "core" (string) $ openclaw path resolve 'oc://x.md/tools/gh/gh' --file frontmatter.md --human leaf @ L9: "GitHub CLI" (string) $ openclaw path find 'oc://x.md/tools/*' --file frontmatter.md --human 3 matches for oc://x.md/tools/*: oc://x.md/tools/gh → node @ L9 [md-item] oc://x.md/tools/curl → node @ L10 [md-item] oc://x.md/tools/send-email → node @ L11 [md-item] ``` The `[frontmatter]` predicate addresses the YAML frontmatter block; `tools` matches the `## Tools` heading via slug, and item leaves keep their slug form even when the source uses underscores (`send_email` → `send-email`). ### JSONC ```text // config.jsonc { "plugins": { "github": {"enabled": true, "role": "vcs"}, "slack": {"enabled": false, "role": "chat"} } } ``` ```bash $ openclaw path resolve 'oc://config.jsonc/plugins/github/enabled' --file config.jsonc --human leaf @ L4: "true" (boolean) $ openclaw path set 'oc://config.jsonc/plugins/slack/enabled' 'true' --file config.jsonc --dry-run --dry-run: would write 142 bytes to /…/config.jsonc { "plugins": { "github": {"enabled": true, "role": "vcs"}, "slack": {"enabled": true, "role": "chat"} } } ``` JSONC edits go through `jsonc-parser`, so comments and whitespace survive a `set`. Run with `--dry-run` first to inspect the bytes before committing. ### JSONL ```text {"event":"start","userId":"u1","ts":1} {"event":"action","userId":"u1","ts":2} {"event":"end","userId":"u1","ts":3} ``` ```bash $ openclaw path find 'oc://session.jsonl/[event=action]/userId' --file session.jsonl --human 1 match for oc://session.jsonl/[event=action]/userId: oc://session.jsonl/L2/userId → leaf @ L2: "u1" (string) $ openclaw path resolve 'oc://session.jsonl/L2/ts' --file session.jsonl --human leaf @ L2: "2" (number) ``` Each line is a record. Address by predicate (`[event=action]`) when you do not know the line number, or by the canonical `LN` segment when you do. ## Subcommand reference ### `resolve ` Read a single leaf or node. Wildcards are rejected — use `find` for those. Exits `0` on a match, `1` on a clean miss, `2` on a parse error or refused pattern. ```bash openclaw path resolve 'oc://AGENTS.md/tools/gh/risk' --human openclaw path resolve 'oc://gateway.jsonc/server/port' --json ``` ### `find ` Enumerate every match for a wildcard / predicate / union pattern. Exits `0` on at least one match, `1` on zero. File-slot wildcards are rejected with `OC_PATH_FILE_WILDCARD_UNSUPPORTED` — pass a concrete file (multi-file globbing is a follow-up feature). ```bash openclaw path find 'oc://AGENTS.md/tools/**/risk' openclaw path find 'oc://session.jsonl/[event=action]/userId' openclaw path find 'oc://config.jsonc/plugins/{github,slack}/enabled' ``` ### `set ` Write a leaf. Pair with `--dry-run` to preview the bytes that would be written without touching the file. Exits `0` on a successful write, `1` if the substrate refuses (for example, a sentinel guard hit), `2` on parse errors. ```bash openclaw path set 'oc://gateway.jsonc/version' '2.0' --dry-run openclaw path set 'oc://gateway.jsonc/version' '2.0' openclaw path set 'oc://AGENTS.md/Tools/+gh/risk' 'low' ``` The `+key` insertion marker creates the named child if it does not already exist; `+nnn` and bare `+` work for indexed and append insertion respectively. ### `validate ` Parse-only check. No filesystem access. Useful when you want to confirm a template path is well-formed before substituting variables, or when you want the structural breakdown for debugging: ```bash $ openclaw path validate 'oc://AGENTS.md/tools/gh' --human valid: oc://AGENTS.md/tools/gh file: AGENTS.md section: tools item: gh ``` Exits `0` when valid, `1` when invalid (with a structured `code` and `message`), `2` on argument errors. ### `emit ` Round-trip a file through the per-kind parser and emitter. The output should be byte-identical to the input on a sound file — divergence indicates a parser bug or a sentinel hit. Useful for debugging substrate behavior on real-world inputs. ```bash openclaw path emit ./AGENTS.md openclaw path emit ./gateway.jsonc --json ``` ## Exit codes | Code | Meaning | | ---- | -------------------------------------------------------------------------- | | `0` | Success. (`resolve` / `find`: at least one match. `set`: write succeeded.) | | `1` | No match, or `set` rejected by the substrate (no system-level error). | | `2` | Argument or parse error. | ## Output mode `openclaw path` is TTY-aware: human-readable output on a terminal, JSON when stdout is piped or redirected. `--json` and `--human` override the auto-detection. ## Notes - `set` writes bytes through the substrate's emit path, which applies the redaction-sentinel guard automatically. A leaf carrying `__OPENCLAW_REDACTED__` (verbatim or as a substring) is refused at write time. - JSONC parsing and leaf edits use the plugin-local `jsonc-parser` dependency, so comments and formatting are preserved on ordinary leaf writes instead of going through a hand-rolled parser/re-render path. - `path` does not know about LKG. If the file is LKG-tracked, the next observe call decides whether to promote / recover. `set --batch` for atomic multi-set through the LKG promote/recover lifecycle is planned alongside the LKG-recovery substrate. ## Related - [CLI reference](/cli)
