# Environment Doctor

## Overview

Run environment diagnostics across 15 check categories. Doctor 2.0 identifies
misconfigured providers, stale loaded or cached plugin versions, invalid plugin
assembly, unwritable state, non-terminal run records, orphan process evidence,
broken hooks, and other issues that prevent Claude Octopus from working
correctly.

**Core principle:** Detect problems before they surface in workflows.


## When to Use

**Use this skill when:**
- Something isn't working and you're not sure why
- After installing or updating the plugin
- Before a demo or important workflow run
- Checking if providers are properly authenticated
- Verifying scheduler, hooks, or skills are correctly configured

**Do NOT use for:**
- First-time setup (use `/octo:setup` — it guides configuration)
- Project workflow status (use `/octo:status`)
- Debugging application code (use `/octo:debug`)


## The Process

### Step 1: Resolve Plugin Root and Run Full Diagnostics

Use this resolver before running Octopus scripts. Prefer the active host root,
then the stable root or the installed CLI. Do not create or replace a stable
link while collecting diagnostics. Run this as a single Bash call.

```bash
OCTO_PLUGIN_ROOT="${CLAUDE_PLUGIN_ROOT:-${CODEX_PLUGIN_ROOT:-}}"
if [[ -z "$OCTO_PLUGIN_ROOT" || ! -x "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" ]]; then
  OCTO_PLUGIN_ROOT="${HOME}/.claude-octopus/plugin"
fi
if [[ ! -x "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" ]] && command -v octopus >/dev/null 2>&1; then
  OCTO_BIN="$(command -v octopus)"
  OCTO_LINK_HOPS=0
  while [[ -L "$OCTO_BIN" ]]; do
    OCTO_LINK_HOPS=$((OCTO_LINK_HOPS + 1))
    if [[ "$OCTO_LINK_HOPS" -le 40 ]]; then
      OCTO_BIN_DIR="$(cd -P "$(dirname "$OCTO_BIN")" 2>/dev/null && pwd -P)" || { OCTO_BIN=""; break; }
      OCTO_LINK_TARGET="$(readlink "$OCTO_BIN")" || { OCTO_BIN=""; break; }
      case "$OCTO_LINK_TARGET" in
        /*) OCTO_BIN="$OCTO_LINK_TARGET" ;;
        *) OCTO_BIN="$OCTO_BIN_DIR/$OCTO_LINK_TARGET" ;;
      esac
    else
      OCTO_BIN=""
      break
    fi
  done
  if [[ -n "$OCTO_BIN" ]]; then
    OCTO_BIN_DIR="$(cd -P "$(dirname "$OCTO_BIN")" 2>/dev/null && pwd -P)" || OCTO_BIN_DIR=""
    [[ -z "$OCTO_BIN_DIR" ]] || OCTO_PLUGIN_ROOT="$(cd "$OCTO_BIN_DIR/.." 2>/dev/null && pwd -P)"
  fi
fi
if [[ ! -x "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" ]]; then
  OCTO_PLUGIN_ROOT="$(
    find "${HOME}/.claude/plugins" -type f -path "*/scripts/orchestrate.sh" -print 2>/dev/null \
      | sed 's#/scripts/orchestrate.sh$##' \
      | { grep -E '(nyldn-plugins|claude-octopus|/octo(/[0-9]|$))' || true; } \
      | sort \
      | tail -1
  )"
fi
if [[ -z "$OCTO_PLUGIN_ROOT" || ! -x "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" ]]; then
  echo "Claude Octopus plugin root not found. Reinstall the octo plugin, then retry doctor diagnostics."
  exit 1
fi
export OCTO_PLUGIN_ROOT
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor --verbose
```

This runs all 15 check categories and displays a formatted report. The
installation category reports a missing or mismatched stable root; it does not
repair it.

### Step 2: Filter by Category (Optional)

If the user asks about a specific area, reuse the resolver from Step 1 and
replace its final `doctor --verbose` invocation with one of these lines. These
are replacement lines, not standalone shell calls; `OCTO_PLUGIN_ROOT` must be
resolved in the same Bash call.

```bash
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor providers
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor providers --live
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor companions
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor auth
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor config
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor updates
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor state
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor smoke
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor hooks
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor scheduler
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor skills
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor conflicts
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor agents
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor recurrence
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor cache
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor installation
```

### Step 3: Check & Install Dependencies

Reuse the Step 1 resolver and replace its final invocation with the dependency
checker to find missing CLIs, statusline config, and recommended plugins:

```bash
bash "$OCTO_PLUGIN_ROOT/scripts/install-deps.sh" check
```

If the check reports missing deps, offer to install them:

```bash
bash "$OCTO_PLUGIN_ROOT/scripts/install-deps.sh" install
```

This auto-installs Codex CLI, jq, and the statusline resolver. Antigravity CLI (`agy`) setup is detected and reported with install guidance. For plugins (claude-mem, document-skills), it prints `/plugin install` commands the user must run manually.

### Step 4: Verbose or JSON Output

As above, run these as the final line of the Step 1 resolver call:

```bash
# Detailed output for troubleshooting
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor --verbose

# Machine-readable output
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor --json

# Combine: specific category + verbose
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor auth --verbose
```

Doctor 2.0 JSON always uses this outer contract:

```json
{
  "schema_version": "10.0",
  "summary": {"passed": 0, "warnings": 0, "failures": 0, "exit_code": 0},
  "results": []
}
```

A check with status `fail` makes both `summary.exit_code` and the process exit
code `1`, while stdout remains valid JSON. Warnings remain structured but do not
make the command fail. Unknown flags, unknown categories, and multiple category
arguments are usage errors with exit code `2`; do not retry them as full scans.

The `providers --live` variant is an explicit, bounded AGY capability check. It
uses one small real request to verify the CLI version, live model catalog and
keyring authentication, configured model, and print-mode dispatch. Do not run
it from startup hooks or routine preflight. If its catalog/auth stage fails,
tell the user to launch plain `agy` and complete the browser sign-in; AGY has no
separate login shell subcommand. On macOS keyring errors, direct them to Keychain
Access, the Antigravity CLI item, and its Access Control settings.

### Step 5: Interactive Remediation (MANDATORY for fixable issues)

After running diagnostics, if ANY fixable issues are found, you MUST use
AskUserQuestion to offer fixes. Do not just print instructions. Offer to
execute them.

Stable-root repair is bounded and requires explicit authorization. First show
the proposed change with:

```bash
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" repair --dry-run
```

Only after the user authorizes that exact repair may you run:

```bash
bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" repair --apply
```

Never recreate the stable link in the resolver or as an automatic doctor
follow-up. Cache cleanup, stale PID cleanup, login flows, package installation,
and plugin updates also require explicit confirmation.

Before each accepted repair, restate the exact target and action. Configuration
repairs must use a validated sibling temporary file and atomic rename; if any
step fails, keep the original and report the failure. Cache cleanup, stale PID
cleanup, login flows, package installation, and plugin updates always require
explicit confirmation. After repair, rerun only the affected category first,
then offer a full scan.

**RTK not installed:**

```javascript
AskUserQuestion({
  questions: [{
    question: "RTK saves 60-90% on bash output tokens. Install it now?",
    header: "Install RTK",
    multiSelect: false,
    options: [
      {label: "Install via brew (Recommended)", description: "brew install rtk — fast, macOS"},
      {label: "Install via cargo", description: "cargo install rtk-token-killer"},
      {label: "Skip", description: "Continue without RTK"}
    ]
  }]
})
```

If user chooses install, run it, then offer hook setup.

**RTK installed but hook not configured on macOS/Linux:**

On Windows Git Bash, do not offer `rtk init -g`. RTK uses CLAUDE.md injection
mode there, so report the hook check as skipped.

```javascript
AskUserQuestion({
  questions: [{
    question: "RTK is installed but the Claude Code hook isn't active. Configure it?",
    header: "RTK Hook",
    multiSelect: false,
    options: [
      {label: "Run rtk init -g (Recommended)", description: "Auto-installs Claude Code bash hook on macOS/Linux"},
      {label: "Skip", description: "I'll configure it later"}
    ]
  }]
})
```

**Missing optional providers:**

```javascript
AskUserQuestion({
  questions: [{
    question: "Some providers are missing. Install them?",
    header: "Providers",
    multiSelect: true,
    options: [
      {label: "Codex CLI", description: "npm install -g @openai/codex"},
      {label: "Antigravity CLI", description: "Install agy, then verify with agy --version && agy models"},
      {label: "Skip all", description: "Continue with available providers"}
    ]
  }]
})
```

**Auth expired:**
Offer to run the login command for the expired provider.

**Multiple fixable issues:** Batch them into a single AskUserQuestion with multiSelect where appropriate, rather than asking one at a time.


## Check Categories

| Category | What it checks |
|----------|---------------|
| `providers` | Claude Code version, Codex CLI installed, Antigravity CLI installed, Perplexity API key, Ollama local LLM (server + models), circuit breaker status, provider fallback history |
| `companions` | Optional companion tools and integrations |
| `auth` | Authentication status for each provider |
| `config` | Plugin version, install scope, feature flags, strict `claude plugin validate` result |
| `updates` | Loaded, installed, catalog, and cache versions; Claude marketplace auto-update; reload requirement |
| `state` | Project state.json, workspace and probe-cache writability, stale results, non-terminal runs, orphan and stale PID evidence |
| `smoke` | Smoke test cache, model configuration |
| `hooks` | hooks.json validity, hook scripts |
| `scheduler` | Scheduler daemon, jobs, budget gates, kill switches |
| `skills` | Skill files loaded and valid |
| `conflicts` | Conflicting plugins detection |
| `agents` | Agent definitions, worktree isolation, CLI registration, version compatibility |
| `recurrence` | Failure pattern detection — flags repeated quality gate failures, source hotspots, 48h trends |
| `cache` | Cache size, freshness, and hygiene |
| `installation` | Loaded plugin root, stable root, host-scoped install metadata, and context profile |

Software dependency installation is checked separately by
`scripts/install-deps.sh check` in Step 3, including Node.js, jq, provider CLIs,
RTK token compression, the statusline resolver, and recommended plugins.


## Interpreting Results

### Healthy Output

All checks pass — no action needed.

### Common Issues and Fixes

| Issue | Fix |
|-------|-----|
| Codex CLI not found | `npm install -g @openai/codex` or install via `codex login` |
| Antigravity CLI not found | Install `agy`, then verify with `agy --version` and `agy models` |
| Perplexity not configured | `export PERPLEXITY_API_KEY="pplx-..."` (optional) |
| Auth expired | Re-run `codex login`; for AGY, launch plain `agy` and complete its browser sign-in |
| Circuit breaker OPEN | Provider had 3+ consecutive transient failures — wait for cooldown or check provider status |
| Stale state | Delete `.octo/state.json` and re-initialize |
| Invalid hooks.json | Check `hooks.json` syntax — must be valid JSON |
| RTK not installed | Offer to install: `brew install rtk && rtk init -g` (saves 60-90% tokens). Use AskUserQuestion to offer brew vs cargo install. |
| RTK installed but hook not configured | On macOS/Linux, offer `rtk init -g`; on Windows Git Bash, report skipped because RTK uses CLAUDE.md injection mode |
| RTK gain stats unavailable | Run some bash commands first, then check `rtk gain` to see token savings |
| Conflicting plugins | Uninstall conflicting plugins or adjust scope |


## Integration with Other Skills

| Scenario | Route |
|----------|-------|
| Doctor finds missing provider | Suggest `/octo:setup` to configure |
| Doctor finds stale project state | Suggest `/octo:status` to review |
| Doctor finds hook errors | Guide user to fix hooks.json |
| All checks pass, user still has issues | Suggest `/octo:debug` for deeper investigation |


## Context and intensity profiles

The installation report exposes two optional context settings:

- `OCTOPUS_CONTEXT_PROFILE` selects `core`, `orchestration`, or `full` context
  behavior. The `octopus profile` command reads and writes this setting.
- `OCTOPUS_HOOK_PROFILE` can override the optional context-hook profile with
  `core`, `orchestration`, or `full`.

These settings control optional context work only. They never disable safety or
lifecycle hooks. A missing or invalid hook-profile registry fails closed.

`OCTO_PROFILE` is a separate legacy intensity setting with `budget`,
`balanced`, and `quality` values. It is not an alias for either context
setting, and it must not be used to claim that safety hooks are disabled.


## Legacy intensity profile

Some older workflow paths use `OCTO_PROFILE` as an intensity setting for model
selection, phase skipping, and context verbosity. This setting is separate
from the optional context-hook profiles above.

### What the Doctor Checks

- **Context profile**: `OCTOPUS_CONTEXT_PROFILE` value, default `core`
- **Optional hook profile**: `OCTOPUS_HOOK_PROFILE` when set, otherwise the
  context profile
- **Legacy intensity**: `OCTO_PROFILE` when a legacy workflow reads it
- **Hook gating**: optional context hooks only; safety and lifecycle hooks remain
  active
- **Model hints**: which model (sonnet/opus) is recommended for each phase
- **Context verbosity**: compressed/standard/full

### Legacy intensity summary

| Dimension | budget | balanced | quality |
|-----------|--------|----------|---------|
| Models | Sonnet everywhere | Sonnet + Opus for synthesis | Opus for most phases |
| Phases | Skip discover if context given | Skip re-discovery | All phases run |
| Context | Compressed | Standard | Full inlining |

### Optional context profile summary

| Dimension | core | orchestration | full |
|-----------|------|----------------|------|
| Optional context hooks | Off | Workflow context only | All profile-managed context hooks |
| Safety and lifecycle hooks | Active | Active | Active |


## Project Tier Hint

Also report `OCTO_TIER` when set. This is a recommendation hint, not a hard policy.

| Tier | Doctor guidance |
|------|-----------------|
| `prototype` | Prefer faster checks and warn before high-cost provider fanout |
| `mvp` | Use balanced defaults and consensus on risky changes |
| `production` | Recommend full verification, security review, and stricter release gates |

If unset, show `OCTO_TIER=unset` and suggest setting it only when the project has a stable risk profile.


## Remote Session Checks

If `CLAUDE_CODE_REMOTE=true` or `OCTOPUS_REMOTE_SESSION=true`, report:

- remote session detected
- autonomous mode default active when no explicit autonomy is set
- provider probes skipped to conserve time/quota
- full HUD disabled unless `OCTOPUS_REMOTE_STATUSLINE=full`
- provider CLIs may need to be installed in the cloud setup script

Suggest `/octo:setup` only for configuration guidance; do not recommend interactive provider logins inside the remote session.


## Runtime Context

The doctor checks for project-level `RUNTIME.md` — a file that provides project-specific context (API endpoints, env vars, test commands, build steps) to orchestration prompts.

### What the Doctor Checks

- **RUNTIME.md exists** in the project root (also checks `.octopus/RUNTIME.md` and `.claude-octopus/RUNTIME.md`)
- If missing, suggest creating one from the template: `cp "${HOME}/.claude-octopus/plugin/config/templates/RUNTIME.md" ./RUNTIME.md`
- If present, confirm it contains at least one populated section (not just the template defaults)

### Why It Matters

Without a `RUNTIME.md`, orchestration prompts lack project-specific details — leading to generic advice about test commands, environment variables, and build steps. A populated `RUNTIME.md` makes every workflow more accurate.


## Quick Reference

`/octo:doctor` was removed in v9.41.0 to preserve Claude Code's native `/doctor` command.
Invoke this manual skill explicitly, or run the CLI directly:

| What to say / run | Action |
|-------------------|--------|
| `/octo:skill-doctor` | Run all 15 categories inside Claude Code |
| `octopus doctor providers` | Check provider installation only |
| `octopus doctor auth --verbose` | Detailed auth status |
| `octopus doctor --json` | Machine-readable output |
| `bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor auth --verbose` | Detailed auth status when the CLI is unavailable |
| `bash "$OCTO_PLUGIN_ROOT/scripts/orchestrate.sh" doctor --json` | Machine-readable output when the CLI is unavailable |

If the `octopus` CLI is not on `PATH`, resolve and export `OCTO_PLUGIN_ROOT`
with the Step 1 resolver, then run the equivalent `scripts/orchestrate.sh`
command directly.
