rename_concept

Destructive

Rename a concept slug across the ontology graph: moves the .md file and rewrites all backlinks in one atomic operation. Runs as a dry-run preview until confirmed.

Instructions

⚠ MULTI-FILE WRITE — change a slug and update every backlink in one atomic graph-level operation. The node UID is preserved; only its current human-readable slug changes. Renames the .md file (oldSlug → newSlug, directory move OK), updates the moved file's frontmatter slug: key, and rewrites every backlink — frontmatter array entries (capabilities / elements / dependencies / relates / contains / describes), inline-string keys, and body links [[oldSlug]] / (oldSlug.md). Tail-only references (mcp-server for capabilities/mcp-server) are also redirected to the new tail. Two-stage safety:

Without confirm: true the call is a dry-run — returns updates (each affected file with before/after array keys + bodyChanged flag) without writing.
With confirm: true the file is moved and all backlinks are rewritten in one pass. Throws if oldSlug missing or newSlug already taken (unless overwrite: true). Use this instead of patch_concept + N find_backlinks + N patch_concept loops. Confirmed writes return compact postWriteMaintenance (maintenance_plan) with count-safe byPhase / bySeverity / byKind queue buckets, action score, executable proposedAction, and current-page nextExecutableAction / nextReviewAction pointers for the final graph.

Input Schema

TableJSON Schema

Name	Required	Description
`confirm`	No	Actually perform the rename when true. Omit or false for a dry-run preview.
`newSlug`	Yes	Target vault-relative slug (omit the .md extension). Directories are created if needed.
`oldSlug`	Yes	Current vault-relative slug (omit the .md extension).
`overwrite`	No	Allow overwriting an existing file at newSlug. Defaults to false (throws if newSlug exists).
`expected_mtime`	No	Optional conflict guard for oldSlug. Pass the `mtime` from get_concept; throws VaultConflictError if the source has been modified externally since you read it.

Output Schema

TableJSON Schema

Name	Required	Description
`ok`	Yes
`uid`	Yes
`moved`	Yes
`dryRun`	Yes
`changed`	No
`message`	No
`newSlug`	Yes
`oldSlug`	Yes
`warnings`	No
`canConfirm`	Yes	True only when repeating the call with confirm:true can perform the previewed change without another explicit safety opt-in.
`sourcePath`	Yes
`targetPath`	Yes
`wouldChange`	Yes	True only when the dry-run predicts a disk or Git change.
`previewReady`	Yes	True only when this response is a complete dry-run preview that an agent can review.
`blockedReasons`	Yes	Machine-readable human explanations for every condition currently blocking confirmation.
`backlinkUpdates`	Yes
`postWriteMaintenance`	No	Compact maintenance_plan summary for post-write follow-up. Bucket maps describe the remaining queue after the write.

A4.8/5.0

Behavior5/5

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

Annotations already flag destructiveHint=true/readOnlyHint=false, and the description adds substantial behavior beyond them: atomic multi-file write, two-stage dry-run/confirm safety, backlink rewrite mechanics (frontmatter arrays, inline keys, body links, tail-only refs), overwrite and expected_mtime conflict guards, and post-write maintenance output. Very rich disclosure for a destructive tool.

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

Conciseness4/5

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

Front-loaded with the ⚠ warning and a clear numbered two-stage safety list, so the most important information comes first. It is somewhat long, with detailed backlink enumeration and postWriteMaintenance description that could be trimmed, but nearly every clause carries operational meaning.

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

Completeness5/5

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

Despite an output schema existing, the description still sketches return shape (updates, postWriteMaintenance) and fully covers the destructive-write path, safety gating, and failure modes. Given the complexity of an atomic multi-file graph operation, nothing an agent needs to call it correctly is missing.

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

Parameters4/5

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

Schema coverage is 100% so the baseline is 3, but the description adds contextual meaning: confirm as a two-stage dry-run toggle, overwrite's default-false throw semantics, and expected_mtime as a conflict guard against external modification tied to get_concept's mtime. This goes beyond the schema's per-parameter text.

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?

States a specific verb+resource with precise scope: 'change a slug and update every backlink in one atomic graph-level operation,' and clarifies the UID is preserved. It distinguishes itself from siblings by naming patch_concept, find_backlinks, and merge-style operations. An agent can tell exactly what changes and what does not.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

Explicitly routes the agent: 'Use this instead of patch_concept + N find_backlinks + N patch_concept loops,' and defines the dry-run vs confirm:true workflow. It also states throw conditions (missing oldSlug, taken newSlug unless overwrite). When-to-use, alternatives, and failure modes are all covered.

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