Instructions
Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.
This server publishes no instructions, or was last inspected before Glama recorded them.

Tools
Functions exposed to the LLM to take actions
| Name | Description |
|---|---|
| interactive_openroad_queryA | Execute a read-only OpenROAD command (report_*, get_*, check_*, sta, help, etc.). Use this for querying design state, generating reports, and inspecting timing. Commands that modify design state are blocked — use interactive_openroad_exec instead. |
| interactive_openroad_execA | Execute a state-modifying OpenROAD command (set_*, create_*, read_*, write_*, flow commands). Use this for loading designs, running placement/routing, applying constraints, and writing output files. Read-only commands are blocked — use interactive_openroad_query instead. |
| list_interactive_sessionsA | List all active interactive OpenROAD sessions. |
| create_interactive_sessionC | Create a new interactive OpenROAD session. |
| terminate_interactive_sessionA | Terminate an interactive OpenROAD session. |
| inspect_interactive_sessionA | Get detailed inspection data for an interactive OpenROAD session. |
| get_session_historyC | Get command history for an interactive OpenROAD session. |
| get_session_metricsB | Get comprehensive metrics for all interactive OpenROAD sessions. |
| list_report_imagesB | List available report images from ORFS runs organized by stage. |
| read_report_imageC | Read a report image and return base64-encoded data with metadata. |

Scored across 10 tools
The query/exec split is clearly disambiguated by read-only vs state-modifying behavior with explicit cross-references. Session management, command execution, and report image tools each have distinct targets, though inspect_interactive_session and get_session_metrics have slight semantic overlap.
Most tools follow a clear verb_noun pattern: list/create/terminate/inspect/get/read. However, interactive_openroad_query and interactive_openroad_exec put the verb at the end and do not match the otherwise consistent session/report naming pattern.
Ten tools is well-scoped for the server's purpose: command execution, session lifecycle, session introspection, and report image access. Each tool has a clear role and no redundant additions inflate the count.
The tool surface covers session creation/listing/termination, read/write command execution, history/metrics, and report image retrieval. Minor gaps exist, such as no explicit session attach or live output streaming, but the core workflows are fully usable without dead ends.
