v2.2.1

• Fix stale closure: handleSubmit dependency array now includes lastPrompt, inputHistory, onAbort
• Simplify UI: all slash commands pass through to loop's command registry (removed 30+ case statements)
• Did-you-mean: typos like /commti suggest /commit
• InputBox: width calculation safe on tiny terminals, shorter placeholder
• Tool timer: hides "0s" for sub-second tools

v2.2.0 — Command Registry + 7 Bug Fixes

Architecture: Command Registry

60+ slash commands extracted from loop.ts (938→564 lines) into a dedicated commands.ts module with:

• Direct commands: Execute immediately (/status, /diff, /log, /stash, /doctor, etc.)
• Rewrite commands: Transform to agent prompts (/commit, /review, /test, /fix, etc.)
• Argument commands: Parse args and rewrite (/explain, /search, /find, /refactor, etc.)

Bug Fixes

• Partial response saved on Esc abort (was losing streamed content)
• Tool result aggregate cap breaks immediately (was iterating)
• AskUser returns error on EOF (was misleading string)
• SSE buffer overflow logged in debug mode
• Glob depth increased to 50 (monorepo support)
• Read offset=0 treated as 1 (1-based)

v2.1.0 — Built-in MCP, Security Hardening, 12 Bug Fixes

Built-in @blockrun/mcp

RunCode now ships with BlockRun MCP server pre-configured — zero setup needed:

• blockrun_search — web search
• blockrun_exa — neural research
• blockrun_dex — DEX prices
• blockrun_markets — prediction markets
• blockrun_chat — second opinion from other models

Just run runcode start — tools are automatically available.

Security Hardening

• Project MCP trust: .mcp.json files in project directories now require explicit trust before loading. Prevents malicious repos from executing arbitrary commands.
• Write symlink check: Target file symlinks are now resolved before writing. Prevents writing to /etc/passwd through a symlink.

12 Bug Fixes

• MCP: 5s connect timeout, 30s tool call timeout, transport leak cleanup
• Session: JSONL corruption recovery, prune protects active session
• Tokens: anchor sanity check on history mutation
• LLM: malformed tool JSON logged instead of silent {}
• Tools: truncation at line boundaries, imagegen download 30s timeout
• Compact: threshold capped at 8-20 messages (was unbounded %)

v2.0.0 — MCP Support + Token Management

MCP Support (Model Context Protocol)

RunCode now connects to MCP servers, giving the agent access to external tools:

// ~/.blockrun/mcp.json
{
  "mcpServers": {
    "blockrun": {
      "transport": "stdio",
      "command": "npx",
      "args": ["@blockrun/mcp"]
    }
  }
}

The agent automatically discovers and uses MCP tools:

• blockrun_search — web search
• blockrun_exa — neural research
• blockrun_markets — prediction markets
• blockrun_dex — DEX prices
• Any third-party MCP server

Use /mcp to see connected servers and tools.

Token Management

• API-anchored tracking (actual counts from API, estimates for new messages)
• /context now shows: Tokens: ~45,200 / 200k (22.6%) ✓
• Anchor resets on compaction for accuracy

v1.8.0 — 40+ Commands, Sessions, Plan Mode

RunCode v1.8.0

Session Persistence

Conversations auto-save. /sessions lists them, /resume <id> continues where you left off.

Plan Mode

/plan restricts to read-only tools for safe exploration. /execute restores full access.

AskUser Tool

Agent can ask you clarifying questions with suggested answers — no more guessing.

40+ Slash Commands

Coding: /commit /review /test /fix /debug /explain /search /find /refactor /scaffold /init /todo /deps

Git: /push /pr /undo /status /diff /log /branch /stash /unstash

Analysis: /security /lint /optimize /clean /migrate /doc

Session: /plan /execute /sessions /resume /compact /context /retry /tasks /doctor

Tool Upgrades

• Read: directories return listing, binary files detected
• Grep: multiline + before/after context
• WebFetch: JSON formatting, cleaner HTML
• Task: delete action + summary counts

v1.7.2

Help panel: organized into Coding/Git/Analysis/Session sections. All 40+ slash commands fully routed through Ink UI.

v1.7.1

/security audit, /lint quality check, /doc docs, /migrate check, /clean dead code removal.

v1.7.0 — Git Workflow + Scaffolding

/push — push to remote. /pr — create pull request via gh CLI. /undo — soft reset last commit. /scaffold — generate boilerplate. /optimize — performance analysis.

v1.6.5

Fix stats display alignment. Minor polish.

v1.6.4

Bash: sets RUNCODE=1 env var so scripts can detect runcode. Grep: before_context (-B) and after_context (-A) params for asymmetric context.
