-`project_number`: The project's number. (number, required)

-**list_project_fields** - List project fields

-`after`: Forward pagination cursor. Use when thepreviousresponse'spageInfo.hasNextPage=true. Supply pageInfo.nextCursor as 'after' and immediately request the next page. LOOP UNTIL pageInfo.hasNextPage=false (don't stop early). Keep per_page identical for every page. (string, optional)

-`before`: Backward pagination cursor(rare): supply to move to the preceding page usingpageInfo.prevCursor. Not needed for normal forward iteration. (string, optional)

-`after`: Forward pagination cursor fromprevious pageInfo.nextCursor. (string, optional)

-`before`: Backward pagination cursorfrom previouspageInfo.prevCursor (rare). (string, optional)

-`owner`: If owner_type == user it is the handle for the GitHub user account. If owner_type == org it is the name of the organization. The name is not case sensitive. (string, required)

-`owner_type`: Owner type (string, required)

-`per_page`: Results per page (max 50). Keep constant across paginated requests; changing mid-sequence can complicate page traversal. (number, optional)

-`per_page`: Results per page (max 50) (number, optional)

-`project_number`: The project's number. (number, required)

-**list_project_items** - List project items

-`after`: Forward pagination cursor. Use when thepreviousresponse'spageInfo.hasNextPage=true. Supply pageInfo.nextCursor as 'after' and immediately request the next page. LOOP UNTIL pageInfo.hasNextPage=false (don't stop early). Keep query, fields, and per_page identical for every page. (string, optional)

-`after`: Forward pagination cursor fromprevious pageInfo.nextCursor. (string, optional)

-`before`: Backward pagination cursorfrom previouspageInfo.prevCursor (rare). (string, optional)

-`fields`: Field IDs to include (e.g.["102589", "985201"]). CRITICAL: Always provide to get field values. Without this, only titles returned. Get IDs from list_project_fields first. (string[], optional)

-`owner`: If owner_type == user it is the handle for the GitHub user account. If owner_type == org it is the name of the organization. The name is not case sensitive. (string, required)

-`owner_type`: Owner type (string, required)

-`project_number`: The project's number. (number, required)

-`query`: Query string - For advanced filtering of project items using GitHub's search syntax:

MUST reflect user intent; strongly prefer explicit content type if narrowed:

- "open issues" → state:open is:issue

- "merged PRs" → state:merged is:pr

- "items updated this week" → updated:>@today-7d (omit type only if mixed desired)

- "list all P1 priority items" → priority:p1 (omit state if user wants all, omit type if user specifies "items")

- "list all open P2 issues" → is:issue state:open priority:p2 (include state if user wants open or closed, include type if user specifies "issues" or "PRs")

- "all open issues I'm working on" → is:issue state:open assignee:@me

Query Construction Heuristics:

a. Extract type nouns: issues → is:issue | PRs, Pulls, or Pull Requests → is:pr | tasks/tickets → is:issue (ask if ambiguity)

b. Map temporal phrases: "this week" → updated:>@today-7d

c. Map negations: "excluding wontfix" → -label:wontfix

d. Map priority adjectives: "high/sev1/p1" → priority:high OR priority:p1 (choose based on field presence)

e. When filtering by label, always use wildcard matching to account for cross-repository differences or emojis: (e.g. "bug 🐛" → label:*bug*)

f. When filtering by milestone, always use wildcard matching to account for cross-repository differences: (e.g. "v1.0" → milestone:*v1.0*)

Syntax Essentials (items):

AND: space-separated. (label:bug priority:high).

OR: comma inside one qualifier (label:bug,critical).

NOT: leading '-' (-label:wontfix).

Hyphenate multi-word field names. (team-name:"Backend Team", story-points:>5).

Quote multi-word values. (status:"In Review" team-name:"Backend Team").

Ranges: points:1..3, updated:<@today-30d.

Wildcards: title:*crash*, label:bug*.

Assigned to User: assignee:@me | assignee:username | no:assignee

Common Qualifier Glossary (items):

is:issue | is:pr | state:open|closed|merged | assignee:@me|username | label:NAME | status:VALUE |

priority:p1|high | sprint-name:@current | team-name:"Backend Team" | parent-issue:"org/repo#123" |

updated:>@today-7d | title:*text* | -label:wontfix | label:bug,critical | no:assignee | has:label

Pagination Mandate:

Do not analyze until ALL pages fetched (loop while pageInfo.hasNextPage=true). Always reuse identical query, fields, per_page.

Recovery Guidance:

If user provides ambiguous request ("show project activity") → ask clarification OR return mixed set (omit is:issue/is:pr). If user mixes project + item qualifiers in one phrase → split: run list_projects for discovery, then list_project_items for detail.

Never:

- Infer field IDs; fetch via list_project_fields.

- Drop 'fields' param on subsequent pages if field values are needed. (string, optional)

-`query`: Query string for advanced filtering of project items. See Projects server instructions (list_project_items query rules) for full construction heuristics, syntax essentials, qualifier glossary, pagination mandate, recovery guidance, and prohibited behaviors. (string, optional)

-**list_projects** - List projects

-`after`: Forward pagination cursor. Use when thepreviousresponse'spageInfo.hasNextPage=true. Supply pageInfo.nextCursor as 'after' and immediately request the next page. LOOP UNTIL pageInfo.hasNextPage=false (don't stop early). Keep query and per_page identical for every page. (string, optional)

-`before`: Backward pagination cursor(rare): supply to move to the preceding page usingpageInfo.prevCursor. Not needed for normal forward iteration. (string, optional)

-`after`: Forward pagination cursor fromprevious pageInfo.nextCursor. (string, optional)

-`before`: Backward pagination cursorfrom previouspageInfo.prevCursor (rare). (string, optional)

-`owner`: If owner_type == user it is the handle for the GitHub user account. If owner_type == org it is the name of the organization. The name is not case sensitive. (string, required)

-`owner_type`: Owner type (string, required)

-`per_page`: Results per page (max 50). Keep constant across paginated requests; changing mid-sequence can complicate page traversal. (number, optional)

-`per_page`: Results per page (max 50) (number, optional)

-`query`: Filter projects by a search query

Scope: title text + open/closed state.
