mureo_strategy_set

Replace the current STRATEGY.md with validated markdown to update goals, constraints, or operation mode. Malformed input is rejected before writing, preventing file corruption.

Instructions

Atomically replace STRATEGY.md with the provided markdown. The content is parsed via parse_strategy() before writing to ensure it is well-formed; a malformed input raises rather than corrupts the file. Use this to update goals, constraints, or operation mode from a chat-only host.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
pathNoOptional path to the file. Defaults to STRATEGY.md / STATE.json in the MCP server's current working directory. Paths outside cwd are refused.
reasonNoWhy this change is being made: one or two sentences naming the evidence and the expected effect. Stored in the journal and on the action_log entry this call produces, for the operator and the next session.
markdownYesThe full new content of STRATEGY.md.

TDQS

A4.2/5.0
Behavior4/5

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

No annotations are provided, so the description carries the full behavioral burden. It discloses atomic replacement, pre-write validation via parse_strategy(), and failure behavior ('raises rather than corrupts the file'). It could additionally mention irreversibility or journaling effects, but the safety-critical behaviors are well covered.

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

Conciseness5/5

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

Two tightly packed sentences front-load the core operation and validation behavior, then provide the use case. There is no filler or repetition; every sentence earns its place.

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

Completeness4/5

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

For a tool with no output schema and no annotations, it covers the key preconditions (well-formedness, atomicity) and the intended chat-host context. It does not describe the return value or explicitly state overwrite irreversibility, but the schema and concise description together give enough to invoke the tool correctly.

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

Parameters3/5

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

Schema description coverage is 100%, so the baseline of 3 applies. The description's reference to 'the provided markdown' matches the required markdown parameter but does not add semantics beyond what the schema already documents for path, reason, and markdown.

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 states a specific verb and resource: 'Atomically replace STRATEGY.md with the provided markdown.' It also names the intended purpose—'update goals, constraints, or operation mode'—and this clearly differentiates it from siblings like mureo_strategy_get and mureo_state_set_* tools.

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?

The description explicitly says 'Use this to update goals, constraints, or operation mode from a chat-only host,' giving a clear usage context. It does not explicitly name when-not-to-use or point to alternative tools, so it falls just short of full routing guidance.

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