offagent 0.10.3

Local-first Office document tooling with a shared CLI and MCP-ready core

Office-Agent

Office-Agent (offagent) is a local-first Office document tool with a shared application core and a CLI entrypoint, offagent.

Detailed technical implementation notes are available in technical-implementation.md.

Office-Agent supports local-first workflows for .docx, .pptx, and .xlsx documents through both a CLI and an MCP server. The app indexes document structure into a local SQLite + FTS5 store, can optionally persist embeddings for semantic and hybrid retrieval, and routes all reads and writes through one shared service layer with path-policy enforcement, stale-locator checks, versioned outputs, and automatic reindexing.

Current Features

Core App

• TOML configuration with environment variable overrides
• office-agent doctor runtime checks for imports, SQLite, FTS5, index writability, configured roots, and vector-search readiness
• document discovery and indexing for .docx, .pptx, and .xlsx
• allowed-root guards for indexed reads and output-root guards for writes
• human-readable, JSON, and quiet CLI output modes
• default versioned write outputs, with optional in-place overwrite when explicitly enabled
• keyword, semantic, and hybrid search modes over indexed content

Structured Document Model

• structured MCP responses backed by the same application services used by the CLI

Vector Search

• optional embedding generation during indexing and reindexing
• SQLite-backed embedding side tables keyed to indexed document items
• semantic retrieval over stored vectors
• hybrid retrieval that combines keyword and semantic scores
• match_mode and per-source score metadata in JSON and MCP search results

Installation

Install the package from Pypi with:

uv install offagent

and running it straight from Pypi:

uvx offagent

The project uses uv for development as well. To install all of the dependencies.

uv sync

Run the CLI with:

uv run offagent --help

Configuration

The CLI accepts an optional config file via --config <path>.

Example office-agent.toml:

[offagent]
index_path = ".offagent/index.sqlite3"
document_roots = ["./docs"]
allowed_roots = ["./docs", "./edited"]
output_directory = "./edited"
output_roots = ["./edited", "./docs"]
allow_inplace_overwrite = true
embedding_model = "BAAI/bge-small-en-v1.5"
embedding_dimensions = 384
vector_search_top_k = 20
hybrid_keyword_weight = 0.4
hybrid_semantic_weight = 0.6

Environment variables override file settings:

• OFFAGENT_CONFIG
• OFFAGENT_INDEX_PATH
• OFFAGENT_DOCUMENT_ROOTS
• OFFAGENT_ALLOWED_ROOTS
• OFFAGENT_OUTPUT_DIRECTORY
• OFFAGENT_OUTPUT_ROOTS
• OFFAGENT_ALLOW_INPLACE_OVERWRITE
• OFFAGENT_EMBEDDING_MODEL
• OFFAGENT_EMBEDDING_DIMENSIONS
• OFFAGENT_VECTOR_SEARCH_TOP_K
• OFFAGENT_HYBRID_KEYWORD_WEIGHT
• OFFAGENT_HYBRID_SEMANTIC_WEIGHT

OFFAGENT_DOCUMENT_ROOTS uses the platform path separator, for example : on macOS/Linux.

Configuration fields:

• index_path: SQLite index file location
• document_roots: directories scanned by discovery and directory-based indexing
• allowed_roots: canonical roots allowed for indexed read operations; empty means no read guard
• output_directory: optional directory for versioned write outputs; defaults to the source document directory
• output_roots: canonical roots allowed for write outputs; if omitted and output_directory is set, this defaults to that directory
• allow_inplace_overwrite: when true, write commands may use --output-mode inplace; default is true
• embedding_model: embedding model name used when generating or querying vectors
• embedding_dimensions: expected vector dimensionality for the configured model
• vector_search_top_k: candidate pool size used by semantic and hybrid retrieval
• hybrid_keyword_weight: keyword contribution to hybrid ranking
• hybrid_semantic_weight: semantic contribution to hybrid ranking

CLI

All commands accept --config <path> after the command name. Example:

uv run offagent search "supplier shall" --config office-agent.toml

Structured commands also accept:

• --json: emit machine-readable JSON with no extra prose
• --quiet: suppress successful stdout output

--json and --quiet are mutually exclusive.

Write commands also accept --output-mode <mode> where <mode> is:

• versioned: default; writes <name>.edited.<timestamp>.<ext> and reindexes the new file
• inplace: overwrites the source file, but only if allow_inplace_overwrite = true

Common exit codes:

• 0: success
• 1: other runtime failure
• 2: invalid arguments or incompatible flag combinations
• 3: not-found target, missing indexed item/document, or stale-locator write failure
• 4: not-editable target
• 5: policy-refused operation

Doctor

Checks runtime health, including vector-search readiness.

Options:

• --config <path>: optional config file path

uv run offagent doctor
uv run offagent doctor --config office-agent.toml

Index And Reindex

index indexes one file or all supported Office files under a directory. reindex currently re-runs the same indexing flow. Add --with-embeddings to generate and persist embeddings during the run.

Arguments:

• path: file or directory to index

Options:

• --with-embeddings: generate embeddings for indexed items during this run
• --config <path>: optional config file path

uv run offagent index ./docs
uv run offagent index ./docs --with-embeddings
uv run offagent index ./docs/sample.docx
uv run offagent index ./docs/sample.pptx
uv run offagent index ./docs/sample.xlsx
uv run offagent reindex ./docs/sample.docx
uv run offagent reindex ./docs/sample.docx --with-embeddings
uv run offagent reindex ./docs/sample.pptx
uv run offagent reindex ./docs/sample.xlsx

Search

Searches indexed content through SQLite FTS5, stored embeddings, or both.

Arguments:

• query: search text

Options:

• --type <docx|pptx|xlsx>: restrict search to one document type
• --doc <path>: restrict search to one indexed document path
• --mode <keyword|semantic|hybrid>: retrieval mode; default keyword
• --config <path>: optional config file path

uv run offagent search "supplier shall"
uv run offagent search "supplier shall" --mode semantic
uv run offagent search "supplier shall" --mode hybrid --json
uv run offagent search "supplier shall" --type docx
uv run offagent search "supplier shall" --type pptx
uv run offagent search "supplier shall" --type xlsx
uv run offagent search "supplier shall" --type docx --doc ./docs/sample.docx
uv run offagent search "supplier shall" --type pptx --doc ./docs/sample.pptx
uv run offagent search "supplier shall" --type xlsx --doc ./docs/sample.xlsx

Notes:

• keyword behaves like the original FTS-only search path
• semantic requires prior indexing with --with-embeddings
• hybrid combines keyword and semantic candidates and returns merged ranking metadata
• JSON output includes match_mode and scores; semantic and hybrid human-readable output also displays that metadata

List

Lists indexed documents with document id, path, type, modified time, and indexed item count.

uv run offagent list
uv run offagent list --json

Show

Shows one indexed document summary, or one indexed item within that document.

uv run offagent show --doc ./docs/sample.docx
uv run offagent show --doc ./docs/sample.docx --item para:3
uv run offagent show --doc ./docs/sample.xlsx --item sheet:Budget2026!B12 --json

Locate

Example query session

Item Id Reference

Use these item-id formats with read, replace, and append:

• DOCX: para:<n>
• PPTX: slide:<slide-number>:shape:<shape-id>
• XLSX: sheet:<worksheet-name>!<cell-coordinate>

Write Behavior

By default, all write commands create a versioned output file:

• sample.docx -> sample.edited.20260318-214512345678.docx
• deck.pptx -> deck.edited.20260318-214512345678.pptx
• budget.xlsx -> budget.edited.20260318-214512345678.xlsx

After a successful write:

• the output file is automatically reindexed
• CLI output reports the written output path
• search results can resolve against the new version immediately
• managed output roots are treated as readable workflow roots so versioned-write follow-up commands continue to work

If the source file changed after indexing:

• the service compares the current file hash to the indexed content_hash
• it tries to re-resolve the same item id against the current file
• if that fails, the command exits with stale-locator error code 3

Development

Run the test suite with:

uv run pytest

This repository also includes an example skill for Office-document workflows at .github/skills/office-agent. The location is VSCode specific but it should work for Claude Code and Codex as well.

Acceptance coverage uses checked-in golden Office fixtures under tests/fixtures, including DOCX, PPTX, and XLSX documents exercised by the CLI and FastMCP integration suites.

The test suite is written in pytest and includes:

• configuration and diagnostics coverage
• path-policy coverage
• SQLite store coverage
• DOCX adapter tests
• DOCX service workflow tests
• PPTX adapter tests
• PPTX service workflow tests
• XLSX adapter tests
• XLSX service workflow tests
• CLI round-trip and acceptance tests for DOCX, PPTX, and XLSX
• FastMCP stdio integration and acceptance tests for the MCP tool surface
• CLI/MCP parity tests for the core index → search → locate → read → replace workflow
