OmniFocus-MCP
OmniFocus MCP Server
Ein Model Context Protocol (MCP)-Server, der OmniFocus mit Claude und anderen MCP-kompatiblen KI-Assistenten verbindet.

Überblick
Dieser Server verbindet KI-Assistenten mit Ihrer OmniFocus-Datenbank. Durch natürliche Konversation kann ein Assistent Aufgaben und Projekte abfragen, erstellen, bearbeiten und entfernen – einschließlich Stapeloperationen. Einige Dinge, die Sie damit tun können:
Ein Syllabus-PDF in ein vollständig spezifiziertes Projekt mit Aufgaben, Tags, Aufschiebedaten und Fälligkeitsdaten übersetzen
Ein Meeting-Transkript in eine Liste von Aktionen verwandeln
Ihre Tags, Projekte und Ordner im Gespräch prüfen und neu organisieren
Visualisierungen Ihrer Aufgaben, Projekte und Tags erstellen
Dutzende von Elementen in einem einzigen Stapelvorgang verarbeiten

Schnellstart
Voraussetzungen
macOS mit installiertem OmniFocus
Node.js 20 oder höher (für
npx)
Beim ersten Gespräch mit OmniFocus fragt macOS, ob Sie den Automatisierungszugriff erlauben möchten. Erlauben Sie es einmal, und Sie sind bereit.
Claude Desktop
Fügen Sie den Server zu ~/Library/Application Support/Claude/claude_desktop_config.json hinzu:
{
"mcpServers": {
"omnifocus": {
"command": "npx",
"args": ["-y", "omnifocus-mcp"]
}
}
}Starten Sie dann Claude Desktop neu.
Claude Code
claude mcp add omnifocus -- npx -y omnifocus-mcpAndere MCP-Clients funktionieren auf die gleiche Weise: Starten Sie npx -y omnifocus-mcp über stdio.
Beispielkonversationen
Gezielte Abfragen:
„Zeig mir alle meine markierten Aufgaben, die diese Woche fällig sind"
„Was sind meine nächsten Aktionen im Ordner Arbeit?"
„Zähle, wie viele Aufgaben in jedem Projekt sind"
Neu organisieren:
„Ich möchte, dass jede Aufgabe ein Energieniveau-Tag hat. Zeig mir eine Liste aller Aufgaben, die keins haben, und deine Vorschläge, welches Tag hinzugefügt werden soll. Ich nehme alle Änderungen vor, die ich für angemessen halte. Dann nimm die Änderungen in OmniFocus vor."
Von überall erfassen:
„Ok, danke für die ausführliche Erklärung, warum die Rechtsstaatlichkeit wichtig ist. Füge meinem Aktivismus-Projekt eine wiederkehrende Aufgabe hinzu, die mich wöchentlich daran erinnert, meinen Abgeordneten anzurufen. Füge eine Zusammenfassung dieses Gesprächs in das Notizfeld ein."
Mit Perspektiven arbeiten:
„Welche Perspektiven habe ich zur Verfügung?"
„Zeig mir, was in meiner Inbox-Perspektive ist"
Transkripte oder PDFs verarbeiten:
„Ich füge das Transkript des heutigen Meetings ein. Bitte analysiere es und erstelle Aufgaben in OmniFocus für alle Aktionspunkte, die mir zugewiesen sind. Lege sie in mein Projekt ‚Produktentwicklung'."
Werkzeuge
Der Server bietet 12 Werkzeuge. Optionale Parameter sind markiert.
query_omnifocus

Wiederkehrende Elemente
add_omnifocus_task, add_project und jedes Element in batch_add_items akzeptieren ein repeat-Objekt; edit_item akzeptiert newRepeat. Sie beschreiben den Zeitplan, und der Server kompiliert die ICS-Wiederholungsregel, sodass Sie nie eine RRULE von Hand schreiben müssen.
Feld | Beschreibung |
|
|
|
|
| Alle N Einheiten wiederholen (Standard 1) |
| Bestimmte Tage, z. B. |
{ "name": "Weekly review", "repeat": { "method": "start-after-completion", "unit": "week" } }
{ "name": "Strength work", "repeat": { "method": "fixed", "unit": "week", "weekdays": ["TU","TH"] } }Wählen Sie method bewusst – es ist das Feld, das am häufigsten von Hand falsch gesetzt wird. Bei fixed erscheinen Vorkommen nach Zeitplan, unabhängig davon, ob das letzte erledigt wurde, sodass eine verpasste Woche einen Rückstand hinterlässt. Bei start-after-completion wird das nächste Vorkommen ab dem tatsächlichen Abschluss geplant, sodass die Gewohnheit einfach wieder aufgenommen wird.
Lesen Sie eine Regel mit query_omnifocus über die Felder repetitionRule (ICS-String) und repetitionMethod zurück oder filtern Sie mit isRepeating.
Derzeit nicht unterstützt: positionsbasierte monatliche Regeln („dritter Dienstag"), bestimmte Monatstage und Endbedingungen (COUNT/UNTIL). Setzen Sie diese direkt in OmniFocus.

Serveranweisungen & Protokollierung
Anweisungen: Während des MCP-Handshakes sendet der Server Nutzungsanleitungen an den Client – Werkzeugauswahl-Empfehlungen (bevorzugen Sie query_omnifocus gegenüber dump_database), Filtertipps und den Ressourcenkatalog. Keine Konfiguration erforderlich.
Protokollierung: Der Server sendet strukturierte Protokolle über das MCP-Protokollierungsprotokoll. Clients können die Ausführlichkeit mit logging/setLevel anpassen (debug, info, warning, error, ...). Skriptausführungszeiten und Fehler werden automatisch protokolliert.
So funktioniert es
Der Server kommuniziert mit OmniFocus über osascript und verwendet dabei JXA (JavaScript for Automation) und OmniFocus' eingebettete Omni Automation (OmniJS), wo dies angebracht ist. Er basiert auf dem offiziellen MCP TypeScript SDK und spricht mit Clients über stdio.
Gemeinsamer Daemon
Das Starten von omnifocus-mcp startet einen kleinen Shim, der sich mit einem gemeinsamen Hintergrund-Daemon verbindet und einen startet, falls noch keiner läuft. Jeder Client auf dem Rechner erhält seine eigene unabhängige MCP-Sitzung, aber alle laufen in diesem einen Prozess.
Das ist wichtig, wenn mehrere Agenten OmniFocus gleichzeitig verwenden. OmniFocus ist eine single-threaded Anwendung, die über AppleEvents gesteuert wird, und der Server begrenzt, wie viele osascript-Aufrufe er gleichzeitig ausführt. Wenn jeder Client seinen eigenen Server hatte, war diese Begrenzung pro Prozess – zehn Clients bedeuteten zehn unabhängige Budgets, die auf eine App gerichtet waren, was zu AppleEvent-Zeitüberschreitungen führte. Durch die gemeinsame Nutzung eines Prozesses wird die Begrenzung global.
Der Daemon lauscht auf einem Unix-Domain-Socket in einem 0700-Verzeichnis (standardmäßig ~/.omnifocus-mcp/daemon-<version>.sock), sodass der Zugriff durch das Dateisystem erzwungen wird – kein Netzwerkport und kein Token. Er beendet sich von selbst, sobald für das Leerlauffenster kein Client verbunden war, und protokolliert in daemon.log neben dem Socket.
Der Socket-Name trägt die Paketversion, sodass ein Upgrade nie dazu führen kann, dass Sie mit dem Daemon der vorherigen Version sprechen. Direkt nach einem Upgrade können Sie kurzzeitig zwei Daemons sehen: Der alte bedient weiterhin die bereits verbundenen Clients und beendet sich, sobald der letzte von ihnen die Verbindung trennt. Clients, die noch mit dem alten Daemon verbunden sind, werden darüber in-band informiert – während ein neuerer Daemon läuft, enthält jedes Tool-Ergebnis einen einzeiligen Upgrade-Hinweis, sodass niemand daran denken muss, sich neu zu verbinden.
An der Client-Konfiguration ändert sich nichts. Wenn der Daemon nicht gestartet werden kann – eine ungewöhnliche Sandbox, ein schreibgeschütztes Home-Verzeichnis – fällt der Shim auf einen eigenständigen Server im Prozess zurück, genau wie in früheren Versionen.

TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries the full burden of behavioral disclosure. While 'Add a new task' implies a write operation, it doesn't specify whether this requires authentication, what happens on success/failure, if there are rate limits, or how errors are handled. For a mutation tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that states the core purpose without any wasted words. It's appropriately sized and front-loaded, making it easy for an agent to quickly understand what the tool does.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool with 8 parameters, no annotations, and no output schema, the description is inadequate. It doesn't explain what happens after task creation, what the return value might be, or provide any behavioral context. The description should do more to compensate for the lack of structured metadata.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all 8 parameters. The description adds no additional parameter information beyond what's already in the schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in the description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Add') and resource ('new task to OmniFocus'), making the purpose immediately understandable. It doesn't differentiate from sibling tools like 'add_project' or 'edit_item', which would require mentioning this is specifically for tasks rather than projects or editing existing items.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
No guidance is provided on when to use this tool versus alternatives like 'add_project', 'edit_item', or 'batch_add_items'. The description doesn't mention prerequisites, context, or any exclusions that would help an agent choose between these sibling tools.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
add_projectC
Add a new project to OmniFocus
| Name | Required | Description | Default |
|---|---|---|---|
| deferDate | No | The defer date of the project in ISO format (YYYY-MM-DD or full ISO date) | |
| dueDate | No | The due date of the project in ISO format (YYYY-MM-DD or full ISO date) | |
| estimatedMinutes | No | Estimated time to complete the project, in minutes | |
| flagged | No | Whether the project is flagged or not | |
| folderName | No | The name of the folder to add the project to (will add to root if not specified) | |
| name | Yes | The name of the project | |
| note | No | Additional notes for the project | |
| sequential | No | Whether tasks in the project should be sequential (default: false) | |
| tags | No | Tags to assign to the project |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool adds a project but doesn't explain what happens upon success (e.g., returns a project ID), error conditions, permissions needed, or side effects. This is inadequate for a mutation tool with zero annotation coverage.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that directly states the tool's purpose without any wasted words. It's appropriately sized and front-loaded, making it easy for an AI agent to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a mutation tool ('add') with no annotations and no output schema, the description is insufficient. It doesn't cover behavioral aspects like return values, error handling, or system impacts, leaving significant gaps for an AI agent to understand how to use it effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already documents all 9 parameters thoroughly. The description adds no additional parameter information beyond what's in the schema. According to the rules, with high schema coverage, the baseline is 3 even with no param info in the description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Add a new project') and target resource ('to OmniFocus'), which is specific and unambiguous. However, it doesn't differentiate from sibling tools like 'add_omnifocus_task' or 'batch_add_items' that might also create items in OmniFocus, so it doesn't reach the highest score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It doesn't mention when to choose 'add_project' over 'add_omnifocus_task' (for tasks vs. projects) or 'batch_add_items' (for bulk operations), nor does it specify prerequisites or exclusions for project creation.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
batch_add_itemsB
Add multiple tasks or projects to OmniFocus in a single operation
| Name | Required | Description | Default |
|---|---|---|---|
| items | Yes | Array of items (tasks or projects) to add |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states it's a batch addition operation. It doesn't disclose behavioral traits such as whether it's idempotent, requires specific permissions, handles errors, or returns any output. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads key information ('Add multiple tasks or projects') without unnecessary words. It earns its place by clarifying the batch nature and target system, making it appropriately sized and well-structured.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given no annotations and no output schema, the description is incomplete for a mutation tool. It lacks details on behavioral context, error handling, or return values, which are crucial for an agent to use it correctly. The high schema coverage doesn't compensate for these gaps in operational transparency.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
The schema description coverage is 100%, so the schema fully documents the 'items' parameter and its nested properties. The description adds no parameter semantics beyond implying batch processing, which is already covered by the tool name and schema. Baseline 3 is appropriate as the schema does the heavy lifting.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Add multiple tasks or projects') and target ('to OmniFocus in a single operation'), making the purpose evident. It distinguishes from single-item tools like 'add_omnifocus_task' and 'add_project' by emphasizing batch capability, though it doesn't explicitly name these siblings.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description implies usage for adding multiple items at once, suggesting it's an alternative to single-item tools. However, it doesn't explicitly state when to use this over siblings like 'add_omnifocus_task' or 'add_project', nor does it mention prerequisites or exclusions, leaving guidance incomplete.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
batch_remove_itemsC
Remove multiple tasks or projects from OmniFocus in a single operation
| Name | Required | Description | Default |
|---|---|---|---|
| items | Yes | Array of items (tasks or projects) to remove |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
No annotations are provided, so the description carries full burden. It states 'Remove' which implies a destructive mutation, but lacks details on permissions, reversibility, confirmation prompts, or error handling for partial failures. For a batch deletion tool with no annotation coverage, this is a significant gap in behavioral disclosure.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core action and resource. Every word earns its place with no redundancy or fluff, making it highly concise and well-structured for quick comprehension.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
Given the tool's complexity (batch destructive operation) and lack of annotations and output schema, the description is insufficient. It doesn't cover critical aspects like return values, error conditions, or side effects. For a mutation tool with no structured safety hints, more completeness is needed to guide safe agent usage.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents the 'items' parameter and its nested properties (id, itemType, name). The description adds no additional parameter semantics beyond implying batch processing. With high schema coverage, the baseline is 3, as the description doesn't compensate but doesn't need to heavily.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Remove multiple tasks or projects') and resource ('from OmniFocus') with the scope of 'in a single operation'. It distinguishes from the sibling 'remove_item' by emphasizing batch capability, though it doesn't explicitly name that sibling. The purpose is specific but could be more precise about differentiation.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like 'remove_item' or other deletion methods. It mentions batch removal but doesn't specify scenarios (e.g., efficiency for bulk cleanup) or prerequisites. Without explicit when/when-not instructions, usage context is implied at best.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
dump_databaseC
Gets the current state of your OmniFocus database
| Name | Required | Description | Default |
|---|---|---|---|
| hideCompleted | No | Set to false to show completed and dropped tasks (default: true) | |
| hideRecurringDuplicates | No | Set to true to hide duplicate instances of recurring tasks (default: true) |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure. While 'Gets' implies a read operation, it doesn't specify what 'current state' includes (tasks, projects, tags, etc.), the format of the output, whether this is a heavy operation, or any performance considerations. For a database dump tool with zero annotation coverage, this is insufficient.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that states the core purpose upfront. However, given the complexity of a database dump operation and the many sibling alternatives, this extreme conciseness comes at the cost of helpful context that would aid tool selection.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a database dump tool with no annotations, no output schema, and 15 sibling retrieval tools, the description is incomplete. It doesn't explain what data is included in the dump, the output format, how this differs from more targeted retrieval tools, or any performance implications. The agent lacks sufficient context to use this tool effectively.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema already fully documents both parameters (hideCompleted and hideRecurringDuplicates). The description adds no parameter information beyond what's in the schema, meeting the baseline 3 for high schema coverage.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Gets') and resource ('current state of your OmniFocus database'), providing a specific verb+resource combination. However, it doesn't explicitly distinguish this tool from its many sibling tools that also retrieve task/project data (like get_flagged_tasks, get_inbox_tasks, etc.), which would require a 5.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. With 15 sibling tools that retrieve various subsets of OmniFocus data, the agent receives no help in choosing between a full database dump and more targeted retrieval tools like get_flagged_tasks or filter_tasks.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
edit_itemC
Edit a task or project in OmniFocus
| Name | Required | Description | Default |
|---|---|---|---|
| addTags | No | Tags to add to the task | |
| id | No | The ID of the task or project to edit | |
| itemType | Yes | Type of item to edit ('task' or 'project') | |
| name | No | The name of the task or project to edit (as fallback if ID not provided) | |
| newDeferDate | No | New defer date in ISO format (YYYY-MM-DD or full ISO date); set to empty string to clear | |

| newEstimatedMinutes | No | New estimated minutes | |
| newFlagged | No | Set flagged status (set to false for no flag, true for flag) | |
| newFolderName | No | New folder to move the project to | |
| newName | No | New name for the item | |
| newNote | No | New note for the item | |
| newProjectStatus | No | New status for projects | |
| newSequential | No | Whether the project should be sequential | |
| newStatus | No | New status for tasks (incomplete, completed, dropped) | |
| removeTags | No | Tags to remove from the task | |
| replaceTags | No | Tags to replace all existing tags with |
TDQS
Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden for behavioral disclosure but only states the basic purpose. It doesn't mention that this is a mutation operation (implied by 'Edit'), what permissions are needed, whether changes are reversible, error conditions, or what happens when multiple parameters are provided simultaneously (e.g., addTags vs replaceTags).
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that states the core purpose without unnecessary words. It's appropriately sized for a tool with comprehensive schema documentation, though it could benefit from additional context about usage and behavior.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a complex mutation tool with 16 parameters, no annotations, and no output schema, the description is inadequate. It doesn't explain what the tool returns, error handling, or behavioral nuances. The agent must rely entirely on the input schema for understanding, which lacks context about how the edit operation actually works in practice.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so all parameters are documented in the schema itself. The description adds no additional parameter information beyond what's in the schema. According to scoring rules, when schema coverage is high (>80%), the baseline is 3 even with no param info in description.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Edit') and target ('a task or project in OmniFocus'), providing specific verb+resource. However, it doesn't distinguish this from sibling tools like 'remove_item' or 'add_omnifocus_task' beyond the basic edit vs add/remove distinction, missing opportunities to clarify scope boundaries.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives. It doesn't mention prerequisites (like needing an existing item ID), when to choose edit over remove+add, or how it differs from batch operations available in sibling tools like 'batch_add_items' or 'batch_remove_items'.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
remove_itemC
Remove a task or project from OmniFocus
| Name | Required | Description | Default |
|---|---|---|---|
| id | No | The ID of the task or project to remove | |
| itemType | Yes | Type of item to remove ('task' or 'project') | |
| name | No | The name of the task or project to remove (as fallback if ID not provided) |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
With no annotations provided, the description carries full burden but only states the action without behavioral details. It doesn't disclose if removal is permanent, requires specific permissions, has side effects, or what happens to dependent items, which is critical for a destructive operation.
Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.
Is the description appropriately sized, front-loaded, and free of redundancy?
The description is a single, efficient sentence that front-loads the core action and resource without any wasted words. It's appropriately sized for a simple tool, making it easy to parse quickly.
Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.
Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?
For a destructive tool with no annotations and no output schema, the description is incomplete. It lacks critical context such as the permanence of removal, error handling, or return values, leaving significant gaps for safe agent invocation.
Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.
Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?
Schema description coverage is 100%, so the schema fully documents all parameters. The description adds no extra meaning beyond implying removal targets tasks or projects, matching the schema. Baseline 3 is appropriate as the schema handles parameter semantics adequately.
Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.
Does the description clearly state what the tool does and how it differs from similar tools?
The description clearly states the action ('Remove') and the resource ('a task or project from OmniFocus'), making the purpose immediately understandable. It doesn't distinguish from sibling tools like 'batch_remove_items' or 'edit_item', which prevents a perfect score.
Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.
Does the description explain when to use this tool, when not to, or what alternatives exist?
The description provides no guidance on when to use this tool versus alternatives like 'batch_remove_items' for multiple items or 'edit_item' for modifications. It also doesn't mention prerequisites or context for removal, leaving usage unclear.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Scored across 7 tools
Most tools have distinct purposes, but there is some overlap between 'remove_item' and 'batch_remove_items', and 'edit_item' could be confused with individual add/edit operations. The descriptions help clarify, but the boundaries between single and batch operations are not perfectly clear.
All tool names follow a consistent snake_case pattern with clear verb_noun structure (e.g., add_omnifocus_task, edit_item, dump_database). There are no deviations in naming conventions, making the set predictable and readable.
With 7 tools, the count is well-scoped for managing tasks and projects in OmniFocus. Each tool serves a clear purpose, from basic CRUD operations to batch processing and database inspection, without feeling excessive or insufficient.
The tool set provides complete coverage for the OmniFocus domain, including create (add_task, add_project), read (dump_database), update (edit_item), and delete (remove_item, batch_remove_items) operations, plus batch additions. There are no obvious gaps that would hinder agent workflows.
