- /shell [cmd]: launch user's $SHELL via tea.ExecProcess (PTY handoff)
hands terminal to the shell and restores TUI on exit.
/shell <cmd> runs that command in the shell directly.
Detects $SHELL > $COMSPEC > /bin/sh|powershell.exe in order.
- bash tool: detect interactive commands before execution
Prefix-interactive: sudo, ssh, passwd, vim/vi/nano, less/more,
htop/top, mysql/psql, ftp/sftp, git push.
Exact-interactive (REPL): python3/python/node/irb/iex/ghci/julia.
Returns a tool result with interactive=true metadata and a hint to
use /shell instead of hanging or erroring.
- completions: add /shell to builtin command list
- help: document /shell [cmd]
- Add tool.PathSensitiveTool interface (ExtractPaths); implement on all 6 fs tools
- Add engine.TurnOptions.AllowedPaths: restricts tool filesystem access per skill invocation
- Bash is denied outright when AllowedPaths is active (unparseable command args)
- fs tools with empty path (cwd default) resolved via os.Getwd() and validated
- Add engine.TurnOptions.AllowedTools + AllowedPaths wiring in pipe mode (main.go) and TUI skill dispatch (tui/app.go)
- Remove TODO(M8.3) from skill.Frontmatter — enforcement is now complete
Adds explicit tier preference to arm selection so the router
deterministically prefers lower-cost arms before falling back:
tier 0: CLI agents (IsCLIAgent=true, subprocess/claude|gemini|vibe)
tier 1: local models (IsLocal=true, ollama/llamacpp)
tier 2: API providers (everything else)
Within a tier, quality/cost scoring still applies. filterFeasible still
gates on quality thresholds, so a low-quality local arm won't beat a
high-quality API arm when the task's minimum threshold rules it out.
Also adds Arm.Disabled: arms with Disabled=true are excluded from
auto-routing but remain selectable via ForceArm.
Implementation: armTier helper + selectBest refactored to try tiers in
order, bestScored picks within a tier. router.Select skips disabled arms
in allArms collection (forced arm bypasses disable check).
Adds internal/provider/subprocess — a provider.Provider that spawns CLI
agents (claude, gemini, vibe) as subprocesses and streams their output.
- FormatParser interface + three parsers for claude-stream-json,
gemini-stream-json, and vibe-streaming formats; fixtures captured from
real binaries
- subprocessStream: pull-based stream.Stream over subprocess stdout with
bounded stderr capture (8KB) and guarded reap() to prevent double-Wait
- DiscoverCLIAgents: parallel PATH scan with 10s timeout, stable ordering
- Provider: only the last user message is passed as --prompt; all other
request fields (history, tools, system prompt) are intentionally ignored
(see package doc)
- main.go: discover and register CLI arms at startup; TODO(P0c) for
tier-based routing to enforce preference order explicitly
Add EffortLevel (auto/low/medium/high) as a provider-agnostic reasoning
control, replacing the Capabilities.Thinking bool. Each provider maps
the level to its native parameter: Anthropic budget tokens (1K/8K/16K),
OpenAI reasoning_effort (low/medium/high), Google thinking budget
(1K/8K/16K). Task classification auto-infers effort from TaskType and
complexity; filterFeasible excludes arms that lack the required level.
Three compounding bugs prevented tool calling with llama.cpp:
- Stream parser set argsComplete on partial JSON (e.g. "{"), dropping
subsequent argument deltas — fix: use json.Valid to detect completeness
- Missing tool_choice default — llama.cpp needs explicit "auto" to
activate its GBNF grammar constraint; now set when tools are present
- Tool names in history used internal format (fs.ls) while definitions
used API format (fs_ls) — now re-sanitized in translateMessage
Additional changes:
- Disable SDK retries for local providers (500s are deterministic)
- Dynamic capability probing via /props (llama.cpp) and /api/show
(Ollama), replacing hardcoded model prefix list
- Engine respects forced arm ToolUse capability when router is active
- Bundled /init skill with Go template blocks, context-aware for local
vs cloud models, deduplication rules against CLAUDE.md
- Tool result compaction for local models — previous round results
replaced with size markers to stay within small context windows
- Text-only fallback when tool-parse errors occur on local models
- "text-only" TUI indicator when model lacks tool support
- Session ResetError for retry after stream failures
- AllowedTools per-turn filtering in engine buildRequest
Stop retrying llama.cpp 500s that are deterministic tool-parse failures
by inspecting the error message body (ClassifyHTTPError). Wrap OpenAI SDK
errors as ProviderError so the engine's retry logic classifies them. Add
localInitPrompt for local models that uses sequential fs_* calls instead
of spawn_elfs (which local models can't produce reliably).
The discovery loop's reconcileArms removed the CLI-forced arm
(llamacpp/default) because the llama.cpp server reports the real model
name (e.g. gemma-26b), creating a mismatch. After 30s the forced arm
disappeared and all subsequent requests failed.
Three-layer fix:
- Eager: query the specific provider at startup to resolve the real
model name before registering the forced arm
- Lazy: reconcileArms detects placeholder "default" arm names and
atomically renames them when discovery reveals the real identity,
with an onReconcile callback to update the session and TUI
- Guard: the forced arm is never garbage-collected by the removal loop
Also fixes misleading /init error messaging — failed inits now show
"loaded from disk (init failed)" instead of "AGENTS.md written to".
- Split app.go (2091→1378 lines) into rendering.go, events.go, init.go
- Add EventRouting stream event for router arm transparency
- Add session auto-naming from first user message
- Add context window progress bar in status bar
- Add /keys cheatsheet, /replay for resumed sessions
- Add inline cost-per-turn after assistant responses
- Add diff previews in fs.write/fs.edit permission prompts
- Collapse tool output to 3 lines by default (ctrl+o expands)
- Use AddPrefix for system context instead of InjectMessage
- Handle ContentThinking and ContentToolResult in session resume
- Show session title in resume picker
- Add /model numeric selection snapshot safety
Tier 1 (launch blockers):
- Remove /shell from /help (advertised but unimplemented)
- Kill dead _ = closeLen assignment
- Cache glamour renderer by width — no longer recreated on every
WindowSizeMsg when width hasn't changed
Tier 2 (ship-quality UX):
- Slash command ghost-text completion with Tab accept. Sources: static
command list + dynamic skill names. /permission gets arg completion
for the 6 modes.
- /compact reports before/after token counts (e.g. "32k → 18k tokens")
- /provider shows all registered arms grouped by provider, not just
"restart required"
- /usage command: input/output/total tokens, context %, provider, turns
- Widen Ctrl+C quit window from 1s to 2s
- "new content below" indicator when scrolled up during streaming
- Permission prompt: inline chat notification when approval needed,
so the user notices even if focused on input
- Fix append footgun: allHooks/allMCPServers allocated fresh to avoid
mutating cfg's backing array (lines 391/413 in main.go)
- Fix pipe-mode permission prompt: detect no-TTY stdin and auto-deny
instead of blocking forever on fmt.Scanln EOF
- Tighten Mistral API key regex from bare [a-zA-Z0-9]{32} (matched
commit hashes, UUIDs) to context-gated pattern requiring "mistral"
keyword nearby. Added scanner test for positives and negatives.
- Remove README demo GIF TODO placeholder
- Unify version string: pass buildVersion from ldflags into tui.Config
instead of hardcoding "v0.1.0-dev"
- Populate benchmarks doc with actual Go benchmark results
Complete the remaining M8 extensibility deliverables:
- MCP client with JSON-RPC 2.0 over stdio transport, protocol
lifecycle (initialize/tools-list/tools-call), and process group
management for clean shutdown
- MCP tool adapter implementing tool.Tool with mcp__{server}__{tool}
naming convention and replace_default for swapping built-in tools
- MCP manager for multi-server orchestration with parallel startup,
tool discovery, and registry integration
- Plugin system with plugin.json manifest (name/version/capabilities),
directory-based discovery (global + project scopes with precedence),
loader that merges skills/hooks/MCP configs into existing registries,
and install/uninstall/list lifecycle manager
- Config additions: MCPServerConfig, PluginsSection with opt-in/opt-out
enabled/disabled resolution
- TUI /plugins command for listing installed plugins
- 54 tests across internal/mcp and internal/plugin packages
Quality feedback integration: TestQualityTracker_InfluencesArmSelection
verifies that 5 successes vs 5 failures tips Router.Select() to the
high-quality arm once EMA has enough observations. Companion test
confirms heuristic fallback below minObservations.
Coordinator tests expanded from 2 → 5: added guidance content check
(parallel/serial/synthesize present), false-positive table extended with
7 cases including the reordered keywords from the previous fix.
Agent tool suite: tool interface contracts for all four tools (Name,
Description, Parameters validity, IsReadOnly). Extracted duplicated
2000-char truncation into truncateOutput() helper (format.go), removing
the inline copies in agent.go and batch.go. Four boundary tests cover
empty, short, exact-max, and over-max cases.
Operational task types (debug, review, refactor, test, explain) now gate
before orchestration in the keyword cascade. Previously, prompts like
"review the orchestration layer" or "refactor the pipeline dispatch"
matched "orchestrat"/"dispatch" and misclassified as TaskOrchestration.
Planning is also moved below the operational types.
Expanded orchestration keywords to cover common intent that the original
four keywords missed: "fan out", "subtask", "delegate to", "spawn elf".
Adds regression tests for false-positive cases and positive tests for new
keywords.
- store: validate session ID against store root to block path traversal in Load/Save
- local: seed turnCount from LocalConfig.TurnCount so resumed sessions keep correct turn count
- main: pass TurnCount from snapshot to LocalConfig on resume
- main: suppress quality.json save when --incognito is active
- main: handle UserConfigDir error in quality save defer instead of silently using wrong path
- test: add TestSessionStore_Load/Save_RejectsPathTraversal
- Add SessionStore field to tui.Config
- Add /resume slash command: lists sessions or restores by ID
- Pass SessionStore to tui.New in main.go
- Update /help text to include /resume
- Add .gnoma/sessions/ to .gitignore
Refactor NewLocal to accept LocalConfig (matching engine/router patterns),
add persistence fields (SessionID, Store, Incognito, Logger), capture
finalState before releasing the lock to avoid data races, and auto-save
a Snapshot after each successful turn when a store is configured.
Add SessionID() to the Session interface and three new tests covering
auto-save, no-store no-panic, and SessionID accessors.
Add custom MarshalJSON/UnmarshalJSON on Content using string type discriminant
("text", "tool_call", "tool_result", "thinking"). Add json tags to Message.
