context-mode v1.0.163

This release adds support for two new AI coding agents — bringing context-mode to 17 supported platforms — alongside a broad round of cross-platform reliability work, security hardening, and context-efficiency improvements. Roughly 30 merged changes across ~20 resolved issues from 14 community contributors since v1.0.162.

Our thanks to everyone who reported, reviewed, and contributed this cycle. The breadth of fixes below — especially across Windows, the Pi/OpenCode/Codex adapters, and session-resume — came directly from the community surfacing real first-run friction.

Headline: GitHub Copilot CLI and Antigravity CLI support

context-mode now integrates with GitHub Copilot CLI and Antigravity CLI (agy), taking supported platforms from 15 to 17 — each with full hook + MCP wiring verified against the upstream agent's own published contract.

• GitHub Copilot CLI — detected via COPILOT_HOME/~/.copilot; all six hook events wired (preToolUse, postToolUse, sessionStart, userPromptSubmitted, agentStop, preCompact); MCP via ~/.copilot/mcp-config.json.
• Antigravity CLI (agy) — detected via ~/.gemini; config + MCP through ~/.gemini/config/; statusline left untouched.

Adapter behavior was validated line-by-line against each agent's published source before merge.

This cycle was carried in large part by @ken-jo, who landed nine pull requests — the two-adapter headline plus a full round of Codex hardening:

Thank you, @ken-jo.

Bug fixes

Adapters

• #787 Add GitHub Copilot CLI + Antigravity CLI support (@ken-jo).
• #822 Pi: stop mutating systemPrompt; inject via context hook to preserve the provider prefix cache (@xuli500177).
• #813 Pi: lazily bootstrap the MCP bridge for agent turns, fixing CLI subcommand hangs (@Gandem).
• #778 Pi: detect the package server via PI_CODING_AGENT (@NgoQuocViet2001).
• #849 OpenCode: write into an existing opencode.jsonc instead of shadowing it with a new opencode.json (verified against OpenCode's config precedence).
• #808 OpenCode: string-aware JSONC stripping via a shared util (@ken-jo).
• #815 OpenCode: preserve ZodEffects preprocess and ZodType coerce in zod3-to-v4 conversion (@LeoNardo-LB).
• #771 Codex: resolve the plugin-manager root for doctor and upgrade (@ken-jo).
• #851 Codex: add MCP tool annotations so ctx_* tools auto-approve instead of being cancelled, restore PreToolUse modify/context (gated on a runtime Codex-capability check so older builds fail closed), and namespace the MCP-readiness sentinel against cross-PID-namespace deletion — resolving #844, #845, #846 (@ken-jo).

Windows and the execution sandbox

• #796 Windows shell runtime selection + PowerShell UTF-8 handling (@Niche-alchemy).
• #839 PowerShell Unicode path handling, including a UTF-8 BOM for reliable script detection (@pradigmaz).
• #826 Preserve Git Bash path conversion for native git (@ken-jo).
• #782 Maven (mvn) on Windows: route the bare mvn token to mvn.cmd, bypassing the MinGW shell branch that left the classpath POSIX-formatted.
• #788 Stop leaking .ctx-mode-* temp directories on Windows (retry cleanup around SQLite WAL/SHM handles) and run non-shell ctx_execute in the project working directory.

Hooks and routing

• #834 PreToolUse respects per-subagent ctx tool availability, so subagents that cannot reach ctx_* are no longer hard-blocked (@ken-jo).
• #773 Capture Stop turn-ends as turn_end events (@pg-adm1n).
• #817 Add an opt-in command-size threshold so small Bash calls skip the routing nudge.

Sessions and search

• #780 Session resume no longer re-injects prior-leg events as current; earlier-leg context is preserved but clearly partitioned.
• #840 Data References now reference large captured tool-outputs via ctx_search instead of inlining them, restoring the context-saving guarantee on long sessions.
• #827 ctx_search returns results again on Windows: project-scope filtering now normalizes path separators on both sides.
• #769 Flood-guard counter is now per-subagent rather than process-global, so parallel multi-agent workflows no longer starve each other.
• #797 Statusline resolves the session id from the stdin payload so per-session KPIs render (@0reo).
• #785 Insight counts git_commit events in commit metrics (@daniel-enqz).

Core, server, and runtime reliability

• #841 Hooks survive a mise/asdf/nvm Node patch upgrade: a liveness guard re-resolves the runtime when the pinned execPath no longer exists.
• #833 Server exits on a fatal uncaught-exception storm instead of spinning (@ken-jo).
• #848 Prevent SIGPIPE from killing a child process on background detach (@gboddaer).
• #803 Liveness guard for resolveJavascriptRuntime after a Homebrew Node upgrade (@ousamabenyounes).
• #805 Canonicalize cacheRoot in healCacheMidSession for symlinked ~/.claude (@ousamabenyounes).
• #789 Enforce MAX_CHUNK_BYTES to prevent FTS5 database bloat (@ousamabenyounes).
• #765 Pin Claude ctx_execute working directory to the session cwd (@NgoQuocViet2001).
• #823 Leave a breadcrumb link when sweeping old version directories (@nyxst4ck).

Security

• #763 Harden shell-command evaluation (subshell/operator-aware deny surface, allow-list piggybacking prevention) and fix test isolation (@pg-adm1n).

Install and upgrade

• #810 Skip settings.json wiring only for true plugin installs, so a standalone install is still wired and a plugin install is never over-written (@eejd).
• #768 Version manifests derive from package.json via a single source of truth that fails loud on drift.

Product

• The ctx_insight analytics experience has moved from a local dashboard to a hosted product.
• The landing site and shareable banners now reflect all 17 supported adapters.
