Todoist Setup

Connect your Todoist account so Dex can work with your Todoist tasks whenever you ask — check what's due, create a task there instead of in Dex, or mark something done.

What this enables (on request): Once connected, say "sync with Todoist" — Dex pushes new tasks to the right Todoist project, marks completions, and pulls back tasks you completed or created in Todoist directly. Sync runs on demand; Dex does not poll Todoist in the background without you asking.

What This Enables

Once connected, you can ask Dex to:

  • See what's due: "What's due in Todoist today?" — including alongside your daily plan
  • Create there instead: "Add that to Todoist, not Dex" during triage or any conversation
  • Complete from chat: "Mark the invoice task done in Todoist"
  • Cross-check: "Anything in Todoist that isn't tracked in Dex?"

Privacy

  • Dex reads and writes your Todoist tasks only when you ask it to
  • Your API key stays local in the ignored vault-root .env file. Tracked YAML stores only its variable name.
  • Dex never shares your Todoist data with third parties

When to Run

  • User types /todoist-setup
  • User asks about connecting Todoist or task sync
  • User wants Todoist tasks in daily plans
  • During /integrate-mcp if Todoist is mentioned

Setup Flow

Step 1: Check if Already Connected

  1. Check System/integrations/config.yaml for a todoist: section with enabled: true through core.utils.strict_yaml.load_yaml_path; refuse duplicate keys, aliases, anchors, or merge mappings before reading or writing any setup field.
  2. If enabled, test authentication with the read-only health check
  3. If healthy, skip to Reconfiguration section below
  4. If not configured or unhealthy, continue to Step 2

Step 2: Explain What We're Setting Up

Say:

**Let's connect Todoist to Dex.**

Once connected, you can ask me to check, create, or complete Todoist tasks
right from our conversations.

**What you'll need:**
- Your Todoist API token (I'll show you where to find it)
- About 2 minutes

**Ready to go?**

Wait for confirmation.

Step 3: Enter the API Key Locally

Guide the user:

To get your Todoist API token:

1. Open Todoist (web or app)
2. Go to **Settings** → **Integrations** → **Developer**
3. Copy the **API token** shown there

Do not paste the token into this conversation. Open the ignored vault-root `.env` in your
local editor and replace the placeholder in this line directly:

`TODOIST_API_KEY=<paste token locally here>`

Save the file with mode `0600`, then reply only `saved`. Dex must never echo, read aloud,
log, or include the value in a command, argv, or process environment.

Wait only for the non-secret saved confirmation. Never ask the user to provide or validate the token in chat.

Step 4: Store the Local Credential

Confirm locally that .env defines TODOIST_API_KEY without printing or returning its value. Use python3 -m core.utils.credential_workflow scan for the redacted authority finding; repair permissions/ownership before continuing if it reports an invalid .env authority. Preserve unrelated lines and never place the value in .mcp.json, tracked YAML, a command, argv, logs, transcript, or process environment. Existing .mcp.json is scan/report-only and must remain byte-identical.

Before health, update only the non-secret tracked Todoist fields to enabled: true and api_key_env_var: TODOIST_API_KEY; do not add an api_key field.

Step 5: Test the Connection

Use only Dex's sanitized Python-to-adapter-stdin read-only health path. It resolves .env internally and performs Todoist GET /projects; it does not put the token in the command or environment:

python3 -c 'from core.integrations.task_sync import check_service_health; print(check_service_health("todoist"))'

If the health result is {"healthy": True}:

Connected! Todoist authentication succeeded through the read-only health check.

If it fails:

That API key didn't work. A few things to check:

1. **Copy the full key** — it should be about 40 characters
2. **Check for extra spaces** before or after the key
3. **Regenerate the key** in Todoist Settings → Integrations → Developer

Want to try again?

Retry up to 2 times, then offer to skip and come back later.

Step 6: Choose Default Project

Ask the user which Todoist project should receive Dex tasks:

**Which Todoist project should Dex tasks go into?**

The health check does not enumerate projects. Open Todoist locally and enter the exact project
name you want Dex to use without pasting any credential.

You can pick one default project, or map each Dex pillar to a different project.

**Option A:** All Dex tasks go to one project (simplest)
**Option B:** Map each pillar to a project:
  (Read pillar names from `System/pillars.yaml` and list them here)
  - [pillar 1 name] → [project]
  - [pillar 2 name] → [project]
  - [pillar 3 name] → [project]

Which works for you?

Save their choices for the config file.

Step 7: Save Configuration

Write to System/integrations/config.yaml — update the todoist section. Build pillar_map dynamically from the user's actual pillars in System/pillars.yaml (one entry per pillar id — never assume fixed pillar names); it's used when the user asks Dex to file a task in the matching Todoist project.

todoist:
  enabled: true
  configured_at: YYYY-MM-DD
  auth_type: api_key
  api_key_env_var: TODOIST_API_KEY
  project: <default project name>
  pillar_map:
    [pillar_id]: <Todoist project name>   # one entry per pillar, from pillars.yaml

If the file already exists, only update the todoist: section. Preserve other integration configs.

Step 8: Capability Cascade

Read the integration manifest from this skill's frontmatter. Present:

**Todoist is connected!** Here's what you can do now:

- **Ask about Todoist anytime** — "What's due in Todoist today?", "Add that to
  Todoist", "Mark the invoice task done in Todoist".
- **Bring it into your planning** — during `/daily-plan` or `/triage`, ask Dex to
  include or route to Todoist and it will.
- **Sync on demand** — say "sync Dex with Todoist" and new tasks push, completions flow
  both directions, and tasks you added in Todoist come in for review

**Sync is on demand** — say "sync with Todoist" anytime. Dex doesn't poll in the background.

Troubleshooting

API Key Invalid or Expired

Todoist API keys don't expire unless you regenerate them. If you see auth errors:

  1. Go to Todoist Settings → Integrations → Developer
  2. Copy the current API token (or regenerate if needed)
  3. Update the key by running /todoist-setup again

"Dex doesn't see my Todoist tasks"

Dex only reads Todoist when you ask it to — there is no background sync. Ask directly ("what's in Todoist?") and if that errors, re-run /todoist-setup to check the connection.

"Todoist credential not found"

Re-run /todoist-setup to restore the vault-root .env value and tracked reference.


Reconfiguration

If the user runs /todoist-setup when already configured:

  1. Check current config from System/integrations/config.yaml
  2. Test the existing API key with the read-only authentication health check
  3. Show the current pillar-to-project mapping
  4. Offer options:
    • Update project mapping
    • Update API key
    • Disconnect Todoist

Disconnect Flow

If user wants to disconnect:

  1. Update System/integrations/config.yaml:
    todoist:
      enabled: false
    
  2. Confirm: "Todoist is disconnected. Tasks will no longer sync between systems. Your existing tasks in both Dex and Todoist are unchanged. Run /todoist-setup anytime to reconnect."
