* feat: implement agent plugins (claude-code, codex, aider)
Implement the Agent interface from @agent-orchestrator/core for three
AI coding tools, enabling the orchestrator to launch, detect activity,
and introspect agent sessions.
Claude Code plugin (full implementation):
- JSONL session introspection (summary, session ID, cost, last message type)
- Activity detection via terminal output pattern matching
- Process detection via tmux pane TTY → ps lookup chain
- Launch command generation with permissions/model/prompt support
Codex and Aider plugins (functional stubs):
- Launch command generation with tool-specific flags
- Process detection via TTY lookup
- Stub introspection (no JSONL support yet)
Closes INT-1329

* fix: address PR review — shell escaping, activity detection, tests
- Replace JSON.stringify with POSIX shell escaping (single quotes) for
all agent launch commands to prevent command injection
- Remove `unset CLAUDECODE &&` shell syntax from getLaunchCommand (breaks
execFile); moved to getEnvironment as empty string
- Fix detectActivity returning "exited" for empty pane when process is
confirmed alive — now returns "idle"
- Tighten BLOCKED_PATTERNS to specific error framing (^Error:, ENOENT:,
APIError:, etc.) to avoid false positives on code output
- Check blocked patterns before input patterns to prevent "EACCES:
permission denied" matching INPUT_PATTERNS on the word "permission"
- Remove pgrep fallback in findClaudeProcess (could match wrong session)
- Fix extractCost double-counting: prefer costUSD, fall back to
estimatedCostUsd only when costUSD is absent
- Trim ACTIVE_PATTERNS to stable indicators only
- Add comprehensive vitest tests (127 tests across 3 plugins)

* fix: address Codex review + lint fixes
- Use `ps -eo pid,tty,args` instead of `comm` for process detection so
CLI wrappers (node, python) are correctly identified
- Coerce PID from handle.data with Number() + isFinite() to handle
string-serialized PIDs
- Fix token double-counting: prefer `usage` object, only fall back to
flat `inputTokens`/`outputTokens` when `usage` is absent
- Add `--` before Codex prompt to prevent prompts starting with `-`
from being parsed as CLI flags
- Check blocked patterns before input patterns so "EACCES: permission
denied" isn't misclassified as waiting_input
- Fix lint: merge duplicate imports, strict equality, remove non-null
assertions
- Format with prettier

* fix: multi-pane tmux, EPERM handling, strict process matching
Codex review iteration 1 fixes:
- Iterate all tmux pane TTYs instead of only the first — prevents
false "exited" in multi-pane sessions
- Handle EPERM from process.kill(pid, 0) as "process exists" — EPERM
means the process is alive but we lack permission to signal it
- Use word-boundary regex for process name matching — prevents false
positives on similar names like "claude-code" or paths containing
the substring
- Add tests for EPERM handling, multi-pane detection, and strict
name matching (134 tests total)

* fix: exclude next-env.d.ts from eslint
Auto-generated Next.js type file triggers triple-slash-reference rule.

* fix: address Bugbot review — JSON.parse guard, detectActivity pattern priority
- Guard parseJsonlFile against non-object JSON values (null, arrays,
primitives) that would cause TypeError in downstream extractors
- Split null output (non-tmux → "active") from empty output (tmux → "idle")
so non-tmux runtimes don't falsely report idle
- Reorder pattern matching: idle before blocked so stale errors in the
tmux scrollback don't mask an idle prompt

* refactor: extract shellEscape to @agent-orchestrator/core
Move the duplicated POSIX shell-escaping utility from all three agent
plugins into packages/core/src/utils.ts and re-export from the package
entry point. Plugins now import { shellEscape } from the shared package.
Addresses Bugbot review comment on PR #5.

* fix: add execFileAsync timeouts, use satisfies for plugin exports
- Add { timeout: 30_000 } to all execFileAsync calls (tmux, ps) per
CLAUDE.md convention to prevent hanging on stuck processes
- Replace `const plugin: PluginModule<Agent>` with inline
`export default { ... } satisfies PluginModule<Agent>` to preserve
narrow literal types on manifest fields
Addresses Bugbot review comments on PR #5.

* refactor: rename introspect → getSessionInfo, detectActivity uses JSONL
- Rename Agent.introspect() → getSessionInfo(), AgentIntrospection → AgentSessionInfo
- Claude Code detectActivity: replace tmux screen-scraping with JSONL-based
detection (file mtime + last entry type)
- Remove terminal pattern constants (ACTIVE_PATTERNS, IDLE_PATTERNS, etc.)
- Update all tests: JSONL-based activity tests, renamed introspect blocks
- waiting_input/blocked states deferred to hooks-based implementation (#16)

* feat: add OpenCode agent plugin, integration tests, and CI workflow
- Add agent-opencode plugin with getLaunchCommand, detectActivity,
isProcessRunning, getSessionInfo (27 unit tests)
- Add integration test suite for all 4 agents (claude-code, codex,
aider, opencode) using real binaries in tmux sessions
- Add GitHub Actions CI workflow for integration tests
- Add test:integration script to root package.json

* fix: update core test mocks — introspect → getSessionInfo + isProcessing
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
* fix: address Bugbot review — Windows paths, bytesRead, hardcoded paths
- toClaudeProjectPath: handle Windows backslashes and drive letters
- readLastJsonlEntry: use bytesRead to avoid null character corruption
- Remove duplicate next-env.d.ts eslint ignore entry
- Remove hardcoded developer-specific binary paths from integration tests
- Add isProcessing limitation comments with issue references (#17-19)
