unsave_note

Unbookmark a Substack note and soft-delete it from local cache. Preserves note history while removing it from active outputs, with verification of remote changes.

Instructions

Unbookmark a Substack note remotely and soft-delete it in local cache.

Soft-deletion preserves note history while removing it from active search/list outputs. remote_confirmed=False means the note was still soft-deleted locally, but the tool could not verify the unbookmark on Substack's side.

Behavior4/5

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

With no annotations, the description carries the full burden of behavioral disclosure, and it delivers: it explains the soft-delete side effect, what's preserved (note history), what's affected (active search/list outputs), and the meaning of remote_confirmed=False as a partial-failure state. It could add idempotency behavior or error handling, preventing a 5, but this is well above the minimum.

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?

Three sentences, front-loaded core purpose, with each subsequent sentence adding meaningful behavior about soft-deletion and the remote_confirmed flag. Every word earns its place; no fluff or redundancy. This is textbook conciseness without under-specification.

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?

For a single-parameter, low-complexity tool with an output schema, the description covers the essentials: remote action, local cache behavior, and a partial-failure state. Since an output schema exists, the description needn't explain return values, though it could have addressed edge cases like calling on an already-unsaved note or transient network errors.

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

Parameters3/5

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

Schema coverage is 0% and the description never explicitly explains the url_or_id parameter format or accepted values. However, the parameter name is largely self-descriptive, and the description's mention of remote_confirmed indirectly hints at the identifier's role in the unbookmark operation. A bit more explicit guidance (URL formats, prefix expectations) would justify a higher score.

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 uses a specific verb+resource+scope: 'Unbookmark a Substack note remotely and soft-delete it in local cache.' It clearly distinguishes from sibling unsave_post by scoping to notes and explicitly describes the dual remote/local action. This matches the 'specific verb+resource+scope' high bar.

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 usage context is clearly implied (use when you want to remove a bookmark from a note), but no explicit when/when-not rules or named alternatives are given. Unlike the calibration example that says 'use search_calls_extensive instead,' this description doesn't guide the agent to an alternative sibling, so it earns a 3 for implied usage without exclusions.

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