Add a renderer regression test for long non-JSON tool output so the CLI's fallback rendering path is covered alongside Read and structured tool payload truncation.
Constraint: This follow-up must commit only renderer-related changes
Rejected: Touch commands crate to fix unrelated slash-command work in progress | outside the requested renderer-only scope
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep truncation guarantees covered at the renderer boundary for both structured and raw tool payloads
Tested: cargo fmt --all; cargo test -p claw-cli tool_rendering_ -- --nocapture; cargo clippy -p claw-cli --all-targets -- -D warnings

Auto compaction was keying off cumulative usage and re-summarizing from the front of the session, which made long chats shed continuity after the first compaction. The runtime now compacts against the current turn's prompt pressure and preserves prior compacted context as retained summary state instead of treating it like disposable history.
Constraint: Existing /compact behavior and saved-session resume flow had to keep working without schema changes
Rejected: Keep using cumulative input tokens | caused repeat compaction after every subsequent turn once the threshold was crossed
Rejected: Re-summarize prior compacted system messages as ordinary history | degraded continuity and could drop earlier context
Confidence: high
Scope-risk: moderate
Reversibility: clean
Directive: Preserve compacted-summary boundaries when extending compaction again; do not fold prior compacted context back into raw-message removal
Tested: cargo fmt --check; cargo clippy -p runtime -p commands --tests -- -D warnings; cargo test -p runtime; cargo test -p commands
Not-tested: End-to-end interactive CLI auto-compaction against a live Anthropic session
Extend the CLI renderer's generic tool-result path to reuse the existing display-only truncation helper, so large plugin or unknown-tool payloads no longer flood the terminal while the original tool result still flows through runtime/session state unchanged.
The renderer now pretty-prints structured fallback payloads before truncating them for display, and the test suite covers both Read output and generic long tool output rendering. I also added a narrow clippy allow on an oversized slash-command parser test so the workspace lint gate stays green during verification.
Constraint: Tool result truncation must affect screen rendering only, not stored tool output
Rejected: Truncate tool results at execution time | would lose session fidelity and break downstream consumers
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Keep future tool-output shortening in renderer helpers only; do not trim runtime tool payloads before persistence
Tested: cargo fmt --all; cargo clippy --workspace --all-targets -- -D warnings; cargo test --workspace
Not-tested: Manual interactive terminal run showing truncation in a live REPL session
Some tools, especially Read, can emit very large payloads that overwhelm the interactive renderer. This change truncates only the displayed preview for long tool outputs while leaving the underlying tool result string untouched for downstream logic and persisted session state.
Constraint: Rendering changes must not modify stored tool outputs or tool-result messages
Rejected: Truncate tool output before returning from the executor | would corrupt session history and downstream processing
Confidence: high
Scope-risk: narrow
Directive: Keep truncation strictly in presentation helpers; do not move it into tool execution or session persistence paths
Tested: cargo test -p claw-cli tool_rendering_truncates_ -- --nocapture; cargo test -p claw-cli tool_rendering_helpers_compact_output -- --nocapture
Not-tested: Manual terminal rendering with real multi-megabyte tool output
After the parser can accept thinking-style blocks, the CLI and tools adapters must explicitly ignore them so only user-visible text and tool calls drive runtime behavior. This keeps reasoning metadata from surfacing as text or interfering with tool accumulation.
Constraint: Runtime behavior must remain unchanged for normal text/tool streaming
Rejected: Treat thinking blocks as assistant text | would leak hidden reasoning into visible output and session flow
Confidence: high
Scope-risk: narrow
Directive: If future features need persisted reasoning blocks, add a dedicated runtime representation instead of overloading text handling
Tested: cargo test -p claw-cli response_to_events_ignores_thinking_blocks -- --nocapture; cargo test -p tools response_to_events_ignores_thinking_blocks -- --nocapture
Not-tested: End-to-end interactive run against a live thinking-enabled model
The Rust API layer rejected thinking-enabled responses because it only recognized text and tool_use content blocks. This commit extends the response and SSE parser types to accept reasoning-style content blocks and deltas, with regression coverage for both non-streaming and streaming responses.
Constraint: Keep parsing compatible with existing text and tool-use message flows
Rejected: Deserialize unknown content blocks into an untyped catch-all | would weaken protocol coverage and test precision
Confidence: high
Scope-risk: narrow
Directive: Keep new protocol variants covered at the API boundary so downstream code can make explicit choices about preservation vs. ignoring
Tested: cargo test -p api thinking -- --nocapture
Not-tested: Live API traffic from a real thinking-enabled model
The subagent runtime still advertised and executed only built-in tools, which left plugin-provided tools outside the Agent execution path. This change loads the same plugin-aware registry used by the CLI for subagent tool definitions, permission policy, and execution lookup so delegated runs can resolve plugin tools consistently.
Constraint: Plugin tools must respect the existing runtime plugin config and enabled-plugin state
Rejected: Thread plugin-specific exceptions through execute_tool directly | would bypass registry validation and duplicate lookup rules
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: Keep CLI and subagent registry construction aligned when plugin tool loading rules change
Tested: cargo test -p tools -p claw-cli
Not-tested: Live Anthropic subagent runs invoking plugin tools end-to-end
Expanded the plugin manager so installed plugin discovery now falls back across
install-root scans and registry-only paths without breaking on stale entries.
Missing registry install paths are pruned during discovery, while valid
registry-backed installs outside the install root remain loadable.
Constraint: Keep the change isolated to plugin manifest/manager/registry code
Rejected: Fail listing when any registry install path is missing | stale local state should not block plugin discovery
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Discovery now self-heals missing registry install paths; preserve the registry-fallback path for valid installs outside install_root
Tested: cargo fmt --all; cargo test -p plugins
Not-tested: End-to-end CLI flows with mixed stale and git-backed installed plugins
Expanded the Rust plugin loader coverage around manifest parsing so invalid
permission values, invalid tool permissions, and multi-error manifests are
validated in a structured way. Added scan-path coverage for installed plugin
directories so both root and packaged manifests are discovered from the install
root, independent of registry entries.
Constraint: Keep plugin loader changes isolated to the plugins crate surface
Rejected: Add a new manifest crate for shared schemas | unnecessary scope for this pass
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: If manifest permissions or tool permission labels expand, update both the enums and validation tests together
Tested: cargo fmt --all; cargo test -p plugins
Not-tested: Cross-crate runtime consumption of any future expanded manifest permission variants
The shared /plugins command flow already routes through the plugin registry, but
allowed-tool normalization still fell back to builtin tools when registry
construction failed. This keeps plugin-related validation errors visible at the
CLI boundary and updates tools tests to use the enum-based plugin permission
API so workspace verification remains green.
Constraint: Plugin tool permissions are now strongly typed in the plugins crate
Rejected: Restore string-based permission arguments in tests | weakens the plugin API contract
Rejected: Keep builtin fallback in normalize_allowed_tools | masks plugin registry integration failures
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Do not silently bypass current_tool_registry() failures unless plugin-aware allowed-tool validation is intentionally being disabled
Tested: cargo test -p commands -- --nocapture; cargo test --workspace
Not-tested: Manual REPL /plugins interaction in a live session
The runtime now auto-compacts completed conversations once cumulative input usage
crosses a configurable threshold, preserving recent context while surfacing an
explicit user notice. The CLI also publishes the requested ant-only slash
commands through the shared commands crate and main dispatch, using meaningful
local implementations for commit/PR/issue/teleport/debug workflows.
Constraint: Reuse the existing Rust compaction pipeline instead of introducing a new summarization stack
Constraint: No new dependencies or broad command-framework rewrite
Rejected: Implement API-driven compaction inside ConversationRuntime now | too much new plumbing for this delivery
Rejected: Expose new commands as parse-only stubs | would not satisfy the requested command availability
Confidence: medium
Scope-risk: moderate
Reversibility: clean
Directive: If runtime later gains true API-backed compaction, preserve the TurnSummary auto-compaction metadata shape so CLI call sites stay stable

Not-tested: Live Anthropic-backed specialist command flows; gh-authenticated PR/issue creation in a real repo
This threads typed hook settings through runtime config, adds a shell-based hook runner, and executes PreToolUse/PostToolUse around each tool call in the conversation loop. The CLI now rebuilds runtimes with settings-derived hook configuration so user-defined Claude hook commands actually run before and after tools.
Constraint: Hook behavior needed to match Claude-style settings.json hooks without broad plugin/MCP parity work in this change
Rejected: Delay hook loading to the tool executor layer | would miss denied tool calls and duplicate runtime policy plumbing

The Rust CLI was still surfacing raw markdown fragments and raw tool JSON in places where the terminal UI should present styled, human-readable output. This change routes assistant text through the terminal markdown renderer, strengthens the markdown ANSI path for headings/links/lists/code blocks, and converts common tool calls/results into concise terminal-native summaries with readable bash output and edit previews.
Constraint: Must match Claude Code-style behavior without copying the upstream TypeScript source

The Rust Agent tool only persisted queued metadata, so delegated work never actually ran. This change wires Agent into a detached background conversation path with isolated runtime, API client, session state, restricted tool subsets, and file-backed lifecycle/result updates.

Tighten prompt-mode parity for the Rust CLI by enabling native tools in one-shot runs, defaulting fresh sessions to danger-full-access, and documenting the remaining TS-vs-Rust gaps.
The JSON prompt path now runs through the full conversation loop so tool use and tool results are preserved without streaming terminal noise, while the tool-input accumulator keeps the streaming {} placeholder fix without corrupting legitimate non-stream empty objects.
Constraint: Original TypeScript source was treated as read-only for parity analysis

The REPL now wraps rustyline::Editor instead of maintaining a custom raw-mode

The Rust CLI previously hid init behind the REPL slash-command surface and only
created a starter CLAUDE.md. This change adds a direct `init` subcommand and
moves bootstrap behavior into a shared helper so `/init` and `init` create the
same project scaffolding: `.claude/`, `.claude.json`, starter `CLAUDE.md`, and
local-only `.gitignore` entries. The generated guidance now adapts to a small,
explicit set of repository markers so new projects get language/framework-aware
starting instructions without overwriting existing files.
Constraint: Runtime config precedence already treats `.claude.json`, `.claude/settings.json`, and `.claude/settings.local.json` as separate scopes
Constraint: `.claude/sessions/` is used for local session persistence and should not be committed by default
Rejected: Keep init as REPL-only `/init` behavior | would not satisfy the requested direct init command and keeps bootstrap discoverability low

This adds a small runtime sandbox policy/status layer, threads
sandbox options through the bash tool, and exposes `/sandbox`
status reporting in the CLI. Linux namespace/network isolation
is best-effort and intentionally reported as requested vs active
so the feature does not overclaim guarantees on unsupported
hosts or nested container environments.
Constraint: No new dependencies for isolation support
Constraint: Must keep filesystem restriction claims honest unless hard mount isolation succeeds

Git-aware CLI flows already existed, but branch detection depended on

Constraint: No new dependencies for git integration work
Constraint: Slash-command help/behavior must stay aligned between shared metadata and CLI handlers

Extended thinking needed to travel end-to-end through the API,

The Rust CLI now recognizes explicit local image references in prompt text,
encodes supported image files as base64, and serializes mixed text/image
content blocks for the API. The request conversion path was kept narrow so
existing runtime/session structures remain stable while prompt mode and user
text conversion gain multimodal support.
Constraint: Must support PNG, JPG/JPEG, GIF, and WebP without adding broad runtime abstractions
Constraint: Existing text-only prompt behavior and API tool flows must keep working unchanged
Rejected: Add only explicit --image CLI flags | does not satisfy auto-detect image refs in prompt text

This change makes compaction summaries durable under .claude/memory,

The Rust CLI now stores managed sessions under ~/.claude/sessions,

Startup auth was split between the CLI and API crates, which made saved OAuth refresh behavior eager and easy to drift.

Directive: Keep ephemeral stdio test helpers portable and avoid directly execing freshly written scripts when an interpreter invocation is sufficient
Tested: cargo fmt --all; cargo clippy -p runtime --all-targets -- -D warnings; cargo test -p runtime
Not-tested: Cross-platform behavior outside the current Linux runtime
The dirty stdio slice had two real regressions in its new JSON-RPC test coverage: the embedded Python helper was written with broken string literals, and direct execution of the freshly written helper could fail with ETXTBSY on Linux. The repair keeps scope inside mcp_stdio.rs by fixing the helper strings and invoking the JSON-RPC helper through python3 while leaving the existing stdio process behavior unchanged.
Constraint: Keep the repair limited to rust/crates/runtime/src/mcp_stdio.rs
Constraint: Must satisfy fmt, clippy -D warnings, and runtime tests before shipping
Rejected: Revert the entire JSON-RPC stdio coverage addition | unnecessary once the helper/test defects were isolated

Reformat /compact output for both live and resumed sessions so compaction results are reported in the same structured console style as the rest of the CLI surface. This keeps the behavior unchanged while making skipped and successful compaction runs easier to read.
Constraint: Compact output must stay faithful to the real compaction result and not imply summarization details beyond removed/kept message counts

Reformat /init results into the same structured operator-console style used by the other polished commands so create and skip outcomes are easier to scan. This keeps the command behavior unchanged while making repo bootstrapping feedback feel more intentional.

Extend /config so operators can inspect specific merged sections like env, hooks, and model while keeping the command read-only and grounded in the actual loaded config. This improves Claude Code-style inspectability without inventing an unsafe config editing surface.

Reformat /memory into the same structured console style as the other polished commands and enumerate discovered instruction files in ancestry order with line counts and previews. This makes repo instruction memory easier to inspect without changing the underlying discovery behavior.

Add a minimal runtime stdio MCP launcher that spawns configured server processes with piped stdin/stdout, applies transport env, and exposes async write/read/terminate/wait helpers for future JSON-RPC integration.
The wrapper stays intentionally small: it does not yet implement protocol framing or connection lifecycle management, but it is real process orchestration rather than placeholder scaffolding. Tests use a temporary executable script to prove env propagation and bidirectional stdio round-tripping.
Constraint: Keep the slice minimal and testable while using the real tokio process surface
Constraint: Runtime verification must pass cleanly under fmt, clippy, and tests
Rejected: Add full JSON-RPC framing and session orchestration in the same commit | too much scope for a clean launcher slice
Rejected: Fake the process wrapper behind mocks only | would not validate spawning, env injection, or stdio wiring

Refresh shared slash help and REPL help wording so the command surface reads more like an integrated console, and make successful /clear output match the newer structured reporting style. This keeps discoverability consistent now that status, model, permissions, config, and cost all use richer operator-oriented copy.
