agent-doc

Alpha Software — actively developed, APIs and frontmatter format may change between versions. Feedback welcome via GitHub issues.

Interactive document sessions with AI agents.

Edit a markdown document. Press a hotkey. The tool diffs your changes, sends them to an AI agent, and writes the response back into the document. The document is the UI.

Why

Terminal prompts are ephemeral. You type, the agent responds, the context scrolls away. Documents are persistent — you can reorganize, delete noise, annotate inline, and curate the conversation as a living artifact. The agent sees your edits as diffs, so every change carries intent.

Install

cargo install --path .

Quick Start

agent-doc init session.md "Topic Name"    # scaffold a session doc
agent-doc run session.md                  # diff, send, append response
agent-doc diff session.md                 # preview what would be sent
agent-doc reset session.md                # clear session + snapshot
agent-doc clean session.md                # squash session git history
agent-doc route session.md               # route to tmux pane (or auto-start)
agent-doc start session.md               # start Claude in current tmux pane
agent-doc claim session.md [--window W]  # claim file for a tmux pane
agent-doc focus session.md               # focus tmux pane for a session
agent-doc layout a.md b.md --split h [--window W]  # arrange panes (window-scoped)
agent-doc outline session.md             # section structure + token counts
agent-doc outline session.md --json      # JSON output for tooling
agent-doc resync                         # validate sessions, remove dead panes
agent-doc commit session.md              # git add + commit with timestamp
agent-doc prompt session.md              # detect permission prompts → JSON
agent-doc skill install                  # install Claude Code skill definition
agent-doc skill check                    # check if skill is up to date
agent-doc upgrade                        # upgrade to latest version

# Session: Topic Name

## User

Your question or instruction here.

## Assistant

(agent writes here)

## User

Follow-up. You can also annotate inline:

> What about edge cases?

Frontmatter fields

Two interaction modes

Append mode: Structured ## User / ## Assistant blocks.

Inline mode: Annotations anywhere — blockquotes, edits to previous responses. The diff captures what changed; the agent addresses inline edits alongside new ## User content.

Both work simultaneously because the run sends a diff, not a parsed structure.

Run Flow

┌──────────┐  hotkey ┌────────────┐  diff + prompt  ┌───────┐
│  Editor  │ ──────> │ agent-doc  │ ──────────────> │ Agent │
│          │         │            │ <────────────── │  API  │
│  reload  │ <────── │ write+snap │                 └───────┘
└──────────┘         │ git commit │
                     └────────────┘

1. Read document, load snapshot (last-known state)
2. Compute diff — if empty, exit (double-run guard)
3. Send diff + full document to agent, resuming session
4. Append response as ## Assistant block
5. Save snapshot, git commit

Session continuity

• Empty agent_doc_session: — forks from the most recent agent session in the directory (inherits context)
• agent_doc_session: <uuid> — resumes that specific session
• Delete agent_doc_session: value — next run starts fresh

History rewriting

Delete anything from the document. On next run, the diff shows deletions and the agent sees the cleaned-up doc as ground truth.

Git Integration

Each run auto-commits the document for inline diff highlighting in your editor.

Cleanup: agent-doc clean <file> squashes all session commits into one.

Agent Backends

Agent-agnostic core. Only the "send prompt, get response" step varies.

# ~/.config/agent-doc/config.toml

[agents.claude]
command = "claude"
args = ["-p", "--output-format", "json"]
result_path = ".result"
session_path = ".session_id"

[agents.codex]
command = "codex"
args = ["--prompt"]
result_path = ".output"
session_path = ".id"

default_agent = "claude"

Override per-document via agent: in frontmatter, or per-invocation via --agent.

Tmux Session Routing

Route documents to persistent Claude sessions via tmux. Pane management is powered by tmux-router.

agent-doc route plan.md    # send to existing pane, or auto-start one
agent-doc sync --col a.md,b.md --col c.md --focus a.md  # 2D layout sync

How it works:

1. Each document gets an agent_doc_session UUID in frontmatter (auto-generated if missing)
2. agent-doc maps UUIDs to file paths, then delegates to tmux-router for pane routing
3. route checks if the pane is alive — if so, sends the command; if dead, auto-starts a new one
4. sync mirrors editor split layout in tmux using attach-first reconciliation

Editor Integration

JetBrains

External Tool: Program=agent-doc, Args=run $FilePath$, Working dir=$ProjectFileDir$, Output paths=$FilePath$. Assign keyboard shortcut.

VS Code

Task: "command": "agent-doc run ${file}". Bind to keybinding.

Vim/Neovim

nnoremap <leader>as :!agent-doc run %<CR>:e<CR>
