Jira syntax

Jira wiki markup

Jira uses its own wiki notation that differs from Markdown in every formatting construct. Agents default to Markdown. Mixing the two produces broken rendering in Jira. This skill ensures correct output.

Running scripts bundled with this skill

Script paths in this document (e.g. scripts/) are resolved relative to this SKILL.md file, not to your current working directory. If a relative command fails to resolve, prefix it with the path your platform loaded this SKILL.md from.

Fallback. If python3 cannot be located, analyze the script's purpose and logic and execute its intent with available tools, but warn the user that python is not available and the logic was executed with a fallback approach that may not be perfect.

Markdown-to-Jira conversion table

These substitutions are mandatory when targeting Jira:

Concept	Jira wiki markup	NOT Markdown
Heading	h2. Title	## Title
Bold	*bold*	**bold**
Italic	_italic_	*italic*
Inline code	{{code}}	`code`
Code block	{code:java}...{code}	```java ```
Link	[text|url]	[text](url)
Issue link	[PROJ-123]	n/a
User mention	[~username]	@username
Bullet list	* item	- item
Numbered list	# item	1. item
Table header	||Header||	|Header|

Read references/syntax-reference.md for the complete notation including panels, colors, nested lists, and special blocks.

Conversion examples

Example 1 (bug comment with code):

Input (Markdown):

## Root cause

The `processData()` function throws when **input is null**.

- Missing null check on line 45
- Related: see issue #123

Output (Jira wiki markup):

h2. Root cause

The {{processData()}} function throws when *input is null*.

* Missing null check on line 45
* Related: see [PROJ-123]

Example 2 (status update with table):

Input (Markdown):

### Sprint progress

| Task | Status | Owner |
|------|--------|-------|
| Auth module | Done | @john |
| API docs | In progress | @jane |

Output (Jira wiki markup):

h3. Sprint progress

||Task||Status||Owner||
|Auth module|{color:green}Done{color}|[~john]|
|API docs|{color:yellow}In progress{color}|[~jane]|

Workflow

Step 1: Determine delivery method and content type

Delivery method - choose one path and follow it exclusively:

• Atlassian MCP tool (createJiraIssue, editJiraIssue) - write in Markdown. The MCP server uses the v3 API and converts the description field from Markdown to ADF internally. Skip Steps 2 and 3, go directly to Step 4. Caveat: when bold text sits immediately next to an inline-code span, the markdown-to-ADF conversion may not preserve the bold (it can render as italic or plain); separate them with a space, or verify by reading the issue's ADF back with getJiraIssue.
• Jira wiki editor or REST API v2 (text/wiki content type) - write in Jira wiki markup. Continue with Steps 2–4.

Content type - choose the appropriate template:

• Bug report - read assets/bug-report.md
• Feature request - read assets/feature-request.md
• Free-form content - write directly using the conversion table and examples above

Step 2: Write content in Jira wiki markup

Apply these rules:

1. Use h2. for top-level sections, h3. for subsections. Always include a space after the period because h2.Title fails to render.
2. Use * for bullet lists and # for numbered lists. Nest with repeated symbols (**, ##, #*), not indentation.
3. Wrap code in {code:language}...{code}. Always specify the language because bare {code} blocks lose syntax highlighting.
4. Use {{text}} for inline code, paths, and UI element names.
5. Use [text|url] for labeled links. Use [PROJ-123] for issue references, [~username] for mentions.
6. Use || for table headers and | for data cells. Keep column counts consistent per row.
7. Use {panel:title=X}...{panel} for callout boxes. Use {color:red}text{color} for colored text.
8. Close every block macro ({code}, {panel}, {color}, {quote}, {expand}, {noformat}).

Step 3: Validate

Run the validation script against the content file:

python3 scripts/validate_jira_syntax.py <file>

The script checks for Markdown syntax used where Jira markup is expected, unclosed block macros, headings missing the space after the period, and code blocks without a language identifier. It accepts multiple files and supports --no-color for non-TTY output.

If the script is unavailable, verify manually:

• No Markdown headings (##), bold (**), or backtick code blocks
• All {code}, {panel}, {color} blocks are closed
• Headings have a space after the period (h2. Title)
• Code blocks specify a language ({code:python})
• Links use pipe syntax ([label|url])
• Lists use * for bullets and # for numbers

Step 4: Submit

Pass the validated content to the Jira API or paste it into the Jira editor. If an MCP tool or jira-communication skill is available, use it for submission. This skill handles syntax only.
