## Changelog

Every change recorded for this component, newest first. Days that predate change tracking, or that we cannot explain, say so: "we were watching and nothing happened" and "we were not watching" are different claims.

### 2026-09-21 (score 7)

First indexed and scored.

## MCP tools (5)

### `explore` (~98 tokens)

Understand, locate or resume. The OS inspects git state, picks candidate modules, outlines symbols and injects the applicable rules, all inside one context budget.

Input parameters:

- `depth` (string)
- `intent` (string, required): What you want to understand or find, in plain language.
- `paths` (array): Optional file paths to focus on instead of letting the OS infer them.
- `projectRoot` (string, required): Absolute path of the active workspace.

### `change` (~142 tokens)

Modify or create code. The OS locates the anchor, applies a surgical AST edit, re-anchors symbols and records the touched files.

Input parameters:

- `create` (array)
- `depth` (string)
- `dryRun` (boolean): true to preview edits without writing files, touching the session, or running verification.
- `edits` (array): Surgical replacements. `target` must uniquely match existing text (or pass symbol/startLine/endLine).
- `intent` (string): What the change should accomplish.
- `paths` (array): Used for a read-only preview when no edits are supplied.
- `projectRoot` (string, required): Absolute path of the active workspace.

### `verify` (~121 tokens)

Prove the change runs. With no commands the OS uses .contextos/profile.json or package.json scripts. Output stays out of context; only receipts and failures come back.

Input parameters:

- `command` (string)
- `commands` (array)
- `cwd` (string)
- `grep` (string)
- `id` (string)
- `lines` (number)
- `maxChars` (number)
- `mode` (string)
- `projectRoot` (string, required): Absolute path of the active workspace.
- `timeoutMs` (number)

### `ship` (~114 tokens)

Close the loop: collect touched files and receipts, optionally verify first, export the architecture graph and archive the session.

Input parameters:

- `decision` (object)
- `dryRun` (boolean): true to preview the planned closure (touched files + receipts) without closing the session, writing history or exporting the graph.
- `projectRoot` (string, required): Absolute path of the active workspace.
- `summary` (string): What changed and why; archived with the session.
- `verify`: true to run profile commands, or an explicit list.

### `ops` (~72 tokens)

Manual passthrough to the internal capabilities (legacy facades, session, profile, system). Use only when the intent-level tools are not enough.

Input parameters:

- `action` (string)
- `args` (object)
- `capability` (string, required)
- `projectRoot` (string, required): Absolute path of the active workspace.
