Jira PATCH Request

jira_patch
Read-only

Partially update Jira issues, comments, or worklogs by submitting only the fields that need to change. Reduce response data by filtering with a JMESPath expression.

Instructions

Partially update Jira resources. Returns TOON format by default.

IMPORTANT - Cost Optimization: Use jq param to filter response fields.

Output format: TOON (default) or JSON (outputFormat: "json")

Common operations:

  1. Update issue fields: /rest/api/3/issue/{issueIdOrKey} body: {"fields": {"summary": "Updated title"}} (only updates specified fields)

  2. Update comment: /rest/api/3/issue/{issueIdOrKey}/comment/{commentId} body: {"body": {"type": "doc", "version": 1, "content": [{"type": "paragraph", "content": [{"type": "text", "text": "Updated comment"}]}]}}

  3. Update worklog: /rest/api/3/issue/{issueIdOrKey}/worklog/{worklogId} body: {"timeSpentSeconds": 7200}

Note: PATCH only updates the fields you specify, leaving others unchanged.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
jqNoJMESPath expression to filter/transform the response. IMPORTANT: Always use this to extract only needed fields and reduce token costs. Examples: "issues[*].{key: key, summary: fields.summary}" (extract specific fields), "issues[0]" (first result), "issues[*].key" (keys only). See https://jmespath.org
bodyYesRequest body as a JSON object. Structure depends on the endpoint. Example for issue: {"fields": {"project": {"key": "PROJ"}, "summary": "Issue title", "issuetype": {"name": "Task"}}}
pathYesThe Jira API endpoint path (without base URL). Must start with "/". Examples: "/rest/api/3/project", "/rest/api/3/search/jql", "/rest/api/3/issue/{issueIdOrKey}"
queryParamsNoOptional query parameters as key-value pairs. Examples: {"maxResults": "50", "startAt": "0", "jql": "project=PROJ", "fields": "summary,status"}
outputFormatNoOutput format: "toon" (default, 30-60% fewer tokens) or "json". TOON is optimized for LLMs with tabular arrays and minimal syntax.
Behavior1/5

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

The description claims 'Partially update' (write operation), but annotations include readOnlyHint: true, creating a direct contradiction. No disclosure of side effects or authentication needs.

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

Conciseness4/5

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

Well-structured with sections, but slightly verbose with repeated mentions of TOON. Front-loaded purpose and examples make it easy to scan.

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

Completeness3/5

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

Covers parameters and common operations well, but lacks return value details (no output schema) and the annotation contradiction undermines completeness.

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

Parameters5/5

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

Schema coverage is 100% with detailed descriptions; the description adds extensive examples for body, path, jq, and outputFormat, significantly improving usability.

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 clearly states 'Partially update Jira resources' and distinguishes from siblings like jira_post and jira_put by emphasizing PATCH semantics. Examples reinforce the purpose.

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

Usage Guidelines4/5

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

Provides good usage context with common operations and cost optimization tip, but does not explicitly state when to use alternatives (e.g., PUT for full updates).

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