robodog-terminal 0.3.76

Agentic coding terminal for the shell (runPixel gateway / OpenAI-compatible / offline backends)

robodog-terminal

An agentic coding terminal: a prompted tool-use loop that reads/edits files, runs commands, runs tests, and self-corrects — over pluggable LLM backends. Designed to run leading models on self-hosted gateways (air-gapped, where the usual agentic assistants can't reach), and works equally with OpenAI-compatible models or a fully offline mock.

Install

pip install -U robodog-terminal       # or, from a checkout: pip install -e apps/cli/robodog

Run

The command is dashed (robodog-terminal or the short alias robodogt); the Python package is robodog_terminal with an underscore (python -m robodog_terminal also works).

robodog-terminal --backend openrouter --model anthropic/claude-sonnet-4.6  # live via OpenRouter (provider/model ids)
robodog-terminal --backend openai --model gpt-4o      # live via OpenAI directly (bare ids)
robodog-terminal --backend gateway                    # enterprise box (the gateway / leading models)
robodog-terminal --echo                               # offline demo, no keys
robodog-terminal --backend openai -p "fix x.py and run the tests"   # headless (-p)
python -m robodog_terminal.run_tests                  # test suites (from a checkout)

Configure (first run)

Get a key at openrouter.ai/keys, then either drop it in a config file:

mkdir -p ~/.robodog
echo "ROBODOG_LLM_KEY=<your OpenRouter key>" >> ~/.robodog/config.env
robodog-terminal             # then /doctor to verify what was found

…or keep it in an encrypted KeePass vault instead — no plaintext key on disk:

pip install "robodog-terminal[keepass]"
robodog-terminal
# then, at the prompt:
#   /keepass init <your OpenRouter key>     creates vault + keyfile + loader
#   /keepass                                status; /doctor to verify

command not found right after install? Your pip scripts dir isn't on PATH — the exes live in ..\Scripts relative to the Location: shown by pip show -f robodog-terminal (e.g. ...\AppData\Roaming\Python\Python312\Scripts for a Windows user-level install). Use python -m robodog_terminal as a zero-setup fallback, and see the troubleshooting guide for PATH repair (do not use setx — it truncates long PATHs to 1024 chars), locked-exe upgrade failures, and more.

Other providers (ROBODOG_LLM_URL) and the enterprise gateway (GATEWAY_*) are covered in the repo README.

Config file (.robodog/settings.json)

Scaffold one with /config init (writes to <cwd>/.robodog/settings.json; add --global for ~/.robodog/settings.json, --force to overwrite). /config with no argument shows the effective config and which files were actually loaded.

Where robodog looks, and which one wins

Four locations are merged, in this exact order:

1. <cwd>/.robodog/settings.json   (highest priority)
2. <cwd>/.claude/settings.json
3. ~/.robodog/settings.json
4. ~/.claude/settings.json        (lowest priority)

.claude/settings.json is read too so an existing Claude Code project's settings work unchanged. Missing files are just skipped — you only need the one(s) you actually want.

How "winning" works depends on the field type:

• permissions.allow / permissions.deny — concatenated, not overridden. Every rule from every file that exists applies; there's no way for a user-level file to "cancel" a project-level rule (deny always wins over allow regardless of which file either came from — see below).
• hooks.* — also concatenated; project hooks run before user hooks.
• defaults.* — scalar, first file wins. If both <cwd>/.robodog/settings.json and ~/.robodog/settings.json set "guard", the project one is used and the user one is silently ignored for that key (not merged, not an error).

}

What happens when something's wrong — the exact order things fail in

Nothing here ever crashes startup or the agent loop. Failures degrade in this order, from "whole file ignored" down to "one call proceeds instead of being gated":

1. A settings.json file has invalid JSON → that ONE file is skipped entirely (logged as a warning), the other three still load normally.
2. A permission rule string doesn't parse (doesn't match tool or tool(glob)) → that individual rule is silently dropped; the rest of the list still applies.
3. A hook's matcher is an invalid regex → that hook is skipped for matching purposes (logged), other hooks still run.
4. A hook command fails to spawn, or times out (default 30s, or the hook's own "timeout") → treated as non-fatal and logged; a broken PreToolUse hook does not block the call — it just doesn't run.
5. A PreToolUse hook exits non-zero but not exactly 2 → logged as a warning and the call proceeds. Only exit code 2 blocks (its stderr becomes the block reason shown to the model).
6. A defaults.* value is malformed (typo, wrong type) → see the per-field notes above; permissionMode and netWrites fail toward the safe default, guard is the one exception that fails toward less safety (an unrecognized value behaves like "warn").

Features

Agentic loop — tools (read/write/edit/multi_edit/bash/run_script/run_tests/ glob/grep/list_dir) with read-before-edit, byte-faithful writes + verify-after- write, fuzzy edits, and syntax checks.

Built for flaky gateways — truncation-aware parsing (a cut-off tool call is recovered), a capped reflection loop that re-teaches the format on a malformed call, self-healing error hints (Windows paths, hyphenated skill dirs, json.loads on a dict, a credit-limited 402 auto-retried smaller), jittered Retry-After backoff, multi-format parsing (<tool>/<invoke>, <think> stripping, JSON tool calls).

Windows-smart — auto-translates &&/||, | head/tail/wc/grep, curl→curl.exe, dir /b, 2>/dev/null; UTF-8 end-to-end (no mojibake).

Safe by default — one central guard on every code-executing tool; outward network writes (Jira POST, git push, gh pr create) confirm and block fail-safe when unattended. /net-writes allow|deny|confirm, or press a to always-allow.

Context & concurrency — keep-goal/summarize-middle compaction, on-disk freshness checks, parallel subagents (live progress + model-concurrency cap) plus background subagents (/bg /tasks /tail /kill), a bounded never-overwhelming trace (/verbose for the full feed).

Ergonomics — @file/@folder mentions with tab-completion · atomic /rewind (files + transcript) · JSONL sessions (/resume, --continue) · plan mode · encrypted KeePass vault (/keepass) · skills & custom commands with keyword triggers (.robodog/, .claude/) · CLAUDE.md/ROBODOG.md hierarchy · rich + prompt_toolkit TUI (emoji/color status line, clickable file:line) · /stats (tokens + est. cost), /copy, /save · headless -p (text/json) · /doctor.

Benchmarked at capability parity with a leading agentic coding assistant across 20 agentic scenarios. See docs/TERMINAL_MODE_PLAN.md for the full design and ROADMAP.md for what's shipped/next.

How robodog compares

Criteria most relevant to picking an agentic coding tool. The 8 open-source columns come from a source-level read of each project (see ROADMAP.md for citations). Claude Code is closed-source — its column reflects documented/observed behavior from actual usage, not code I could read, so treat it as less rigorously verified than the other 9. ✅ full support · 🟡 partial · ❌ not found/not present.

Customizable color themes	✅✅ 4 incl. pip-boy	IDE theme	IDE theme	❌	❌	N/A	IDE theme	✅	✅ (inherited)	🟡 light/dark, not arbitrary custom palettes
Loop/repetition breaker — detects the model repeating the same (or same-failing) tool call and intervenes instead of looping forever	✅ counter-based (consecutive-failure + identical-call-repeat thresholds); functional but less sophisticated than the content/LLM-judged detectors below	✅ LoopDetectionTracker soft/hard thresholds + mistake counter (PR #9933); not uniform across all surfaces — open #12293 shows 30+ identical retries observed on one	✅ ToolRepetitionDetector (canonical-hash) + configurable mistake counter, pauses for human input (fixed via #3240)	🟡 hardcoded 3-reflection cap, not repeat-specific detection — open #2385 asks for a real one	🟡 RepetitionInspector exists in code but is a no-op today — the only production call site never sets a limit	✅ StuckDetector — 5 pattern types (repeat action+observation/error, monologue, alternation, context-loop), halts the turn	❌ no mechanism at all; open, unresolved #12702 reproduces exactly this	✅✅ 3 layered mechanisms incl. an LLM-judged semantic loop check every N turns	✅✅ even more elaborate than its own Gemini CLI fork base, tuned against DashScope repetitive-call behavior (#5019)	🟡 unverified (closed-source)
Read-before-edit freshness check — refuses/forces a re-read if the file changed on disk since the model last saw it, instead of silently overwriting a stale in-context copy	✅ explicit mtime tracking per read path; edit is refused and a re-read is forced if the file changed since	🟡 a FileContextTracker exists but isn't wired into the current edit path; protection is implicit (the old text must still match)	🟡 issues #2347/#1891 closed without fixing it; advisory "recently modified" notice only, not enforced for a full overwrite	❌ no mtime/hash tracking found; open #2864 confirms the gap	❌ no tracking found; only re-reads fresh at write time (implicit-only)	🟡 re-reads + exact-match protects against silent overwrite, but no explicit mtime/hash or proactive staleness warning	🟡 gates on "has this path been read at all," not "has it changed since" — no mtime check	🟡 hash comparison exists only in the self-correction retry path, not a general freshness ledger	✅✅ mtime+size+inode tracking with TOCTOU-safe checks at 3 points (pre-read, post-read, pre-write) — more thorough than robodog's	🟡 unverified (closed-source)
Checkpoint/rewind — atomic file + conversation restore — undoes file edits AND the conversation together, not just one or the other	✅ atomic file+transcript restore (shipped 0.3.34); no shadow-git backing store yet	✅ restoreCheckpoint() restores both by default (independently toggleable); against the real .git, not an isolated shadow repo	✅ checkpointRestore() — shadow-git file revert + message rewind in one call ("Restore Files & Task")	❌ /undo only reverts the git commit; chat history untouched — open #2554 asks for the combined version	❌ attempted twice (PRs #3040/#3493), abandoned; maintainers now tell users to do it manually via git commit	❌ conversation fork/navigate exists, but the workspace is shared unchanged across forks — no file snapshot tied to rewind	❌ no native mechanism; the only "checkpoint" hit shells out to an optional external tool just for commit attribution	✅✅ isolated shadow-git repo (its own GIT_DIR, never touches the user's real .git) + full conversation history restored together	🟡 diverged to a custom per-file snapshot system; restores both but sequentially, not truly atomic	🟡 unverified (closed-source)
Subagent default privilege — a delegated subagent defaults to read-only, not full write/execute, unless the caller explicitly opts in	✅✅ defaults to type=explore (read-only); write/execute requires an explicit type=general opt-in — fixed 0.3.73 after a subagent given a read-only-sounding task raced an uncoordinated write against the parent session	🟡 both delegation paths (spawn_agent, named YAML agents) inherit the parent's current mode/full unrestricted tool set by default	🟡 delegated task gets full privileges of whichever mode the LLM picks (usually "code" = read+write+exec); no delegation-aware restriction layer exists	🟡 "Architect" sub-coder is a fixed two-phase pipeline, not general delegation — its whole job is writing files, always full access	🟡 subagent inherits all the parent's enabled extensions unless the caller filters them; sandboxed read-only delegates are a proposed, unshipped discussion (#7159)	🟡 permission_mode defaults to None → inherits the parent's own default (NeverConfirm, i.e. no confirmation, full auto-execute)	🟡 code explicitly grants all-tools-allowed by default with an inline // todo acknowledging the gap; no built-in restricted preset shipped	🟡 subagents inherit all tools unless tools: frontmatter restricts them — same unsafe default robodog itself shipped with before 0.3.73	🟡 defaults to AUTO_EDIT (auto-approves writes, no confirm) unless the parent session itself is in PLAN/strict mode	🟡 unverified (closed-source)
Garbled/truncated model-response resilience — recognizes a response cut off mid-tool-call and retries, rather than misreading it as a final answer or silently executing a corrupted call	✅ detects truncation from an unclosed <tool>/<param> tag independent of finish_reason (an or, not dependent on it being reported at all) and re-prompts for just the tool call; the retry also gets a one-shot escalated max_tokens ceiling (0.3.75)	✅ normalizes truncated finish reasons to a canonical state and raises a distinct, correctly-labeled error — doesn't auto-continue inline, though	❌ only checks for "tool_calls" finish reason; on malformed/incomplete tool-call JSON it explicitly forces the call through as non-partial and executes it anyway, catching problems only via generic param validation afterward	✅ raises a dedicated exception on finish_reason=="length"; malformed edit blocks are caught and trigger an automatic reflection retry, never silently applied	❌ not detected anywhere in the provider layer; two real bugs confirm it (#7239: truncation misread as a parse error; #8167: cutoff surfaces as raw "EOF while parsing a string")	🟡 malformed tool-call JSON is caught and corrected, and an empty response triggers a nudge — but nothing inspects finish_reason itself, so prose truncated by length is treated as a normal final message	❌ JSON parse failures on tool-call arguments are silently swallowed; a truncated call proceeds with empty/partial args rather than being flagged incomplete	🟡 detects truncation and warns the user, but doesn't auto-retry — the turn is still treated as final; a separate open issue shows some configs get no warning at all	✅✅ detects an incomplete tool call mid-stream (before the response even finishes) via JSON bracket-depth tracking, auto-retries with an escalated token ceiling, and explicitly rejects a truncated write with chunking guidance	🟡 unverified (closed-source)
Session persistence / resume — a conversation's full state can be saved to disk and resumed by ID/reference after the process restarts	✅ JSONL sessions, /resume, --continue	✅ resume-by-ID on disk, both the VS Code extension and CLI surfaces	✅ full history reload by task ID from disk, backing the task-history sidebar	🟡 --restore-chat-history genuinely reconstructs the LLM-facing conversation state, but it's one implicit file per working directory — no session-ID system for multiple named sessions	✅ SQLite-backed session store, resume by name/ID after restart	✅ persistent, file-store-backed event log keyed by conversation ID, with an explicit resume-after-restart API	🟡 exists (cn ls/--resume) but confirmed broken for selecting a specific non-latest session by ID (open #12927 — always loads the newest file instead)	✅ /chat save|resume|list|delete <tag>, distinct from its checkpoint/revert feature	✅✅ full session service — per-session JSONL, --continue/--resume with title search, session forking, and crash-recovery detection	🟡 unverified (closed-source)

What robodog covers that most others don't: Unix→Windows command rewriting (the rest either prompt the model to use native syntax or, like Claude Code, do narrower translation) — the only one in the table with a Python-native, explicitly-embeddable core (build_core()) built for that from day one, not retrofitted — and 4 switchable themes vs. everyone else's IDE-inherited or none.

robodog's real gaps — the two rows below are the honest answer to "what's missing": every other tool in this table (including Claude Code) has MCP; robodog doesn't yet (ROADMAP.md Phase 5.1, the single biggest ecosystem unlock available). Sandbox/container isolation is the second gap — OpenHands (Docker) and Gemini CLI/Qwen Code (Docker/podman/seatbelt) have real process-level isolation; robodog has permission gating but no execution sandbox yet (ROADMAP.md Phase 6). Its long-running-command UX (idle-note) is also a notch behind OpenHands' true soft-timeout-with-polling — informational only, doesn't let the model interactively poll or send input mid-command.

Two more honest gaps, from a fresh source-level pass (2026-07-22): robodog's loop-repetition breaker and read-before-edit freshness check both work and are genuinely enforced — but Gemini CLI and Qwen Code's are more advanced on both fronts. Gemini CLI layers three detection mechanisms including an LLM-judged semantic loop check; Qwen Code goes further still, purpose-tuned against real DashScope repetitive-call failures. On freshness, Qwen Code's priorReadEnforcement.ts checks mtime and size and inode at three separate points (pre-read, post-read, immediately pre-write) — robodog's single mtime comparison is real protection but a narrower one. Where robodog holds up well is checkpoint/rewind: its atomic file+transcript restore matches Cline's and Roo Code's (both real, working, if not shadow-git-isolated like Gemini CLI's) and is well ahead of Aider (file-only), goose (abandoned attempts), OpenHands (conversation and files are decoupled), and Continue.dev (no native mechanism at all).

A genuine standout, from the same pass: robodog is the only tool in this table whose subagent delegation defaults to read-only. All 8 open-source tools surveyed have a working delegation/subagent mechanism, and every single one defaults to full or inherited write/execute access — several with the gap explicitly acknowledged in their own source (Continue.dev's executor has an inline // todo about it; goose has an open discussion proposing sandboxed delegates that don't exist yet). Gemini CLI's default is the same shape of bug robodog itself shipped with before 0.3.73 — a subagent inherits everything unless a tools: field explicitly restricts it. On truncated-response resilience robodog now also auto-retries with an escalated max_tokens ceiling (0.3.75, prompted directly by this research). Robodog's own detection was already independent of finish_reason (an unclosed tag is a structural signal, checked regardless of what the provider reports) — different tools, different formats to detect truncation in, same underlying idea. Qwen Code's real edge is architectural, not a design flaw on robodog's side: it runs over a streamed response, so its JSON-depth tracker can flag an incomplete tool call mid-generation, before the response even finishes. Robodog's non-streaming backend path has no "mid-stream" to detect anything in — it only ever sees a complete or cut-off response, never a partial one in flight. robodog is otherwise on par with Cline and Aider, and ahead of Roo Code (which detected malformed truncated JSON but explicitly forces the call through anyway), goose, and Continue.dev (neither handles it at all). Session persistence is a fully solved problem across most of this table, robodog included; Qwen Code's is the most feature-rich (forking, crash-recovery), and Continue.dev is the one with a confirmed, currently open bug in exactly this feature.

On Claude Code specifically: it's the most feature-complete tool in this table overall (widest interface surface, MCP, an Agent SDK, a real settings file) — but "covers everything robodog does" isn't quite accurate: robodog's Windows command-rewriting is more extensive than what's been observed from Claude Code, and Claude Code doesn't ship an embeddable no-UI core the way build_core() is — the Agent SDK is a related but separate product, not the CLI's own internals made importable. Being closed-source also means several rows above are inherently unverifiable rather than confirmed, which is a real asymmetry against the 8 tools whose source I could actually read.

Embedding (using robodog as a library, not the CLI)

robodog_terminal.core.build_core() assembles the agentic core — ToolRegistry

• AgentLoop, with hooks/skills/background/session wiring — with no dependency on the terminal UI or argparse. This is the same function the CLI entrypoint (app.py::main()) calls; it just also wires a UI and a REPL loop on top. An embedder (a web backend, a chat bot, a test harness) can call it directly:

from robodog_terminal.core import build_core
from robodog_terminal.llm_client import EchoClient  # or GatewayClient/OpenAICompatClient

core = build_core(cwd=".", client=EchoClient())
result = core.loop.run("list the files here and summarize the project")
print(result.final_text)

Every UI touchpoint is an optional callback with a safe no-UI default (ask_fn auto-picks the first option; on_diff/on_bash_line/on_confirm/on_event no-op if you don't supply them — though a destructive command under guard="confirm" still fails closed, not open, with no on_confirm wired). Pass your own to hook into a different frontend:

core = build_core(
    cwd=".", client=my_client,
    guard="confirm", on_confirm=lambda cmd, reason: my_approval_ui(cmd, reason),
    on_bash_line=lambda line: my_ui.stream(line),
    on_event=lambda kind, data: my_ui.render(kind, data),
)

See core.py's build_core() docstring for the full parameter list. Three extension points discovered from <cwd>/.robodog/ (mirrored from .claude/ for existing Claude Code projects) come along for free in the returned Core.registry/Core.skills:

• .robodog/settings.json (hooks.py) — permission allow/deny rules and PreToolUse/PostToolUse/Stop hooks, plus a defaults block (permissionMode/guard/netWrites) that seeds build_core()'s own defaults. Scaffold one with /config init in the CLI, or write it directly.
• .robodog/commands/*.md, .robodog/agents/*.md, .robodog/skills/<name>/SKILL.md (skills.py) — custom slash commands, custom subagent types, and keyword-triggered context injection.
• agents.py's AGENT_TYPES — the built-in subagent roster (explore, general); SkillsRegistry.agent_type_overrides() merges file-defined ones in, and build_core() does this merge automatically.
