Pathrule

Pathrule Write Rule

pathrule_write_rule

Create a new rule at a workspace path. Missing nodes auto-create. Use scope_type/priority honestly: high only when a violation causes a real bug or regression. Cloud-only — Pathrule Studio/CLI also renders the rule into the user's CLAUDE.md/AGENTS.md and editor companion files automatically.

Input Schema

TableJSON Schema

Name	Required	Description
`name`	Yes	Short human-readable rule name.
`content`	Yes	Rule body: the instruction agents must follow.
`priority`	Yes	Use high only for rules whose violation causes bugs, security issues, or real regressions.
`node_path`	Yes	Workspace-relative path where the rule applies, e.g. / or /packages/app.
`scope_type`	Yes	Use project for global rules, folder for path-specific rules, or file_type when the rule targets a class of files.
`workspace_id`	Yes	Workspace UUID from pathrule_list_workspaces.
`allow_duplicate`	No	Set true only when intentionally allowing another rule with the same name.

Output Schema

TableJSON Schema

Name	Required	Description
`ok`	Yes	true when the call succeeded. false when it did not, in which case `error` carries the reason and the success fields are absent.
`data`	No	Created rule: id, name, node_id, node_path, version_id.
`error`	No	Present only when ok is false.
`human_message`	No	One-line summary of the result, safe to relay to the user verbatim.

A4.4/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

The description discloses important behavioral traits beyond the annotations: missing nodes auto-create, and the rule is automatically rendered into the user's CLAUDE.md/AGENTS.md and editor companion files. This is valuable side-effect information that annotations do not convey, especially for an agent deciding whether invoking this tool is safe.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is compact: three sentences, each earning its place. It front-loads the core purpose, then adds side effects, then provides parameter stewardship guidance. There is no redundant repetition of the tool name or schema details.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, the description does not need to explain return values. It covers purpose, side effects, parameter guidance, and environment constraints. The main remaining gap is the lack of explicit routing to sibling tools for update/read/delete cases, but the create-focused wording largely compensates.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3. The description adds meaning beyond the schema by explaining that missing nodes auto-create (relevant to node_path) and by giving guidance on honest scope_type/priority usage. This elevates the parameter understanding without fully explaining every parameter, though the schema already covers them well.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states a specific verb and resource: 'Create a new rule at a workspace path.' It clearly distinguishes this from sibling tools like pathrule_update_rule, pathrule_read_rule, and pathrule_delete_rule by emphasizing 'new.' The scope and intent are immediately unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use this tool through 'Create a new rule,' but it does not explicitly say to use pathrule_update_rule for existing rules or pathrule_read_rule for reading. It provides useful context like 'Cloud-only' and cautions about honest scope_type/priority usage, but lacks explicit exclusion statements or alternative routing.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

A3.8/5.0

Disambiguation4/5

Tools are grouped by resource (memory/rule/skill/workspace/snapshot/refresh) and mostly have distinct output shapes, so agents can usually pick the right one. A few retrieval tools (get_context, get_node, get_tree, goto) overlap in purpose, but their descriptions clarify resolution mode vs full tree vs context bundle.

Naming Consistency3/5

All tools share the pathrule_ prefix and mostly follow verb_noun, but the verbs are inconsistent: create_workspace vs write_memory, get_node vs read_memory, delete_skill vs remove_pattern, plus verb-only exceptions like goto, setup, and ping. The pattern is readable but not uniform.

Tool Count2/5

32 tools is above the 25-tool threshold and feels heavy for a single server, even with a broad domain. Several context-retrieval tools and read/list variants could potentially be consolidated, though each tool does have a specific purpose.

Completeness4/5

Core CRUD is covered for memories, rules, and skills, along with workspaces, snapshots, refresh tasks, and pattern import/removal. Minor gaps include no standalone list_rules/list_skills and no snapshot update/delete, but agents can work around these via get_context, goto, and get_tree.
