Return primary-root claim state or a structured migration stop without creating absent state.

Atomically acquire one work item, file domain, or timed resource.

Work-item scope uses work_item_id with activity work or update. Named resources require complete timing evidence resolved against PROJECT.yaml. Project-files excludes backlog and supports caller-requested isolation only beneath the primary worktree's canonical .worktrees/ root, with backlog omitted through worktree-specific sparse checkout. Schema-version-2 results preserve the package-owned claim engine's current outcomes, rejection fields, and exit codes.

Atomically add same-domain scope without weakening existing ownership.

A work-item claim cannot add operational scope. A named resource extension requires complete timing evidence. Primary-only scope from a linked claim returns SHARED_CHECKOUT_REQUIRED; invalid mixed scope leaves the registry unchanged.

Extend one configured resource hard stop with bounded evidence.

Refresh one active claim heartbeat in the repository-global registry.

Release one exact claim, including a disposition for work-item ownership.

Replace the live registry with an empty claim list under its exact lock.

Archive complete UTC claim-event days while retaining the configured hot window.

Report canonical contention metrics without creating or migrating absent state.

Render safe self-contained hierarchy HTML and optionally save it.

Inline mappings, sequences, JSON, and YAML require no filesystem access. An explicit source path, custom theme folder, or output folder must be absolute and resolve beneath MCP_AGENT_OPS_WORKSPACE_ROOTS. When a filename is supplied without an output folder, the authorized server project directory is used.

Create a durable hierarchy JSON plan and its same-named HTML rendering.

Source and theme paths must be absolute beneath configured workspace roots. The output folder follows the same boundary and defaults to the authorized server project directory.

Apply exactly one targeted plan mutation and regenerate its HTML rendering.

The plan path must be absolute beneath configured workspace roots. The target is an exact dotted hierarchy number or an exact unique title. Supply exactly one of completed, text, add_child, replace_children, or add_peer_after.

Validate exact YAML files, including duplicate keys, with structured diagnostics.

Verify local Markdown targets and anchors selected by simple root-relative globs.

Load recursive text references aggregated across every matching allowed folder.

Atomically refresh project and configured user reference scopes.

List path-free skill metadata, digests, resources, and shadowing counts.

Return the precedence-resolved absolute SKILL.md path for one skill name.

Read one precedence-resolved skill and optionally append its extension.

Read one supporting skill resource without permitting directory traversal.

Load skills and optionally append independently resolved extensions.

Load several supporting resources in one ordered all-or-nothing operation.

Atomically refresh project and configured user skill roots.

Validate catalog names or explicit skill paths beneath the working project.

Detect required technology skills for project scopes using the configured registry.
