+# claude-code-routine-trigger-worker
+
+Cloudflare Worker that fires a [Claude Code routine](https://code.claude.com/docs/en/routines) on a precise cron schedule via the [`/fire` API](https://platform.claude.com/docs/en/api/claude-code/routines-fire). Runs on Cloudflare's free tier — no servers, no GitHub minutes, no Docker host.
+
+> [!TIP]
+> **Anthropic's routine editor now ships a built-in cron trigger** — it runs on Anthropic's infra, no setup. Use it first.
+>
+> This worker is for users who want self-hosted-like control without operating their own infra: secrets in CF, logs in CF, schedule in code review.

+
+## Quickstart
+
+```bash
+git clone https://github.com/tiennm99/claude-code-routine-trigger-worker
+cd claude-code-routine-trigger-worker
+npm install
+
+# Upload secrets (from Anthropic routine editor → API trigger)
+echo -n 'https://api.anthropic.com/v1/claude_code/routines/trig_.../fire' \
+  | npx wrangler secret put ROUTINE_FIRE_URL
+echo -n 'sk-ant-oat01-...' \
+  | npx wrangler secret put ROUTINE_FIRE_TOKEN
+
+# Edit the cron schedule and timezone in wrangler.toml, then:
+npx wrangler deploy
+```
+
+Tail logs:
+
+```bash
+npx wrangler tail
+```
+
+A successful fire logs a JSON line with `session_url`. Open it to watch the run.
+
+## Environment variables
+
+Configured in `wrangler.toml` (`[vars]` for plain values) or via `wrangler secret put` (for secrets).
+
+| Name                 | Type   | Required | Default                                  | Notes |
+| -------------------- | ------ | :------: | ---------------------------------------- | ----- |
+| `ROUTINE_FIRE_URL`   | secret | yes      | —                                        | Anthropic `/fire` endpoint. From routine editor → API trigger. |
+| `ROUTINE_FIRE_TOKEN` | secret | yes      | —                                        | `sk-ant-oat01-...` per-routine token. Shown once in the editor. |
+| `TEXT_TEMPLATE`      | var    | no       | `Scheduled trigger at {LocalTime}`       | Token-substitution template. See *Templates*. |
+| `TZ`                 | var    | no       | `UTC`                                    | IANA tz name (`Asia/Ho_Chi_Minh`, `America/New_York`, …). Used for `{LocalTime}` formatting. |
+
+## Customize the schedule
+
+Edit `wrangler.toml` `[triggers].crons` — Cloudflare requires literal cron expressions (same constraint as GitHub Actions). To change when the routine fires:
+
+```toml
+[triggers]
+crons = [
+  "7 17 * * *",   # 00:07 UTC+7
+  "13 22 * * *",  # 05:13 UTC+7
+  # add / remove / edit these lines as needed
+]
+```
+
+Then redeploy: `npx wrangler deploy`.
+
+Tips:
+- Cron runs in **UTC**. Convert your local time: `UTC = local − offset` (e.g. 09:00 UTC+7 → 02:00 UTC → `0 2 * * *`).
+- Validate expressions at <https://crontab.guru/>.
+- **Free tier limit:** 5 cron expressions per worker. Default config uses all 5. To run more schedules, deploy another worker.
+- Scattering minutes (e.g. `7`, `13`, `19`, `23`, `37`) is good hygiene on shared infrastructure even though CF cron is more reliable than GitHub.
+
+## Templates
+
+`TEXT_TEMPLATE` supports these `{Token}` substitutions, rendered per fire. Unknown tokens are left intact in the output.
+
+| Token         | Example                                |
+| ------------- | -------------------------------------- |
+| `{ISO}`       | `2026-05-09T03:19:00.000Z`             |
+| `{LocalTime}` | `2026-05-09 10:19 GMT+7`               |
+| `{Cron}`      | `19 3 * * *` — the expression that fired |
+
+Example:
+
+```toml
+[vars]
+TEXT_TEMPLATE = "Daily digest at {LocalTime} (cron {Cron})"
+TZ = "America/New_York"
+```
+
+## Local development
+
+Copy `.dev.vars.example` to `.dev.vars` and fill in your routine credentials:
+
+```bash
+cp .dev.vars.example .dev.vars
+# edit .dev.vars
+
+npx wrangler dev --test-scheduled
+```
+
+Then trigger a scheduled run:
+
+```bash
+curl "http://localhost:8787/__scheduled?cron=*+*+*+*+*"
+```
+
+`.dev.vars` is gitignored — never commit it.
+
+## Tests
+
+```bash
+npm test
+```
+
+Vitest runs in the Workers runtime via `@cloudflare/vitest-pool-workers`. Tests mock `fetch`, so they consume no Anthropic quota.
+
+## Secret rotation
+
+`wrangler secret put` overwrites silently. Rotate by re-running it with the new value:
+
+```bash
+echo -n 'sk-ant-oat01-newvalue' | npx wrangler secret put ROUTINE_FIRE_TOKEN
+```
+
+The change takes effect on the next deploy or within a few seconds via the live config.
+
+## Beta header
+
+The request pins `anthropic-beta: experimental-cc-routine-2026-04-01` (constant in `worker.js`). When Anthropic ships a new dated beta, bump it via a release. Older dated values keep working for a transition window per Anthropic's beta policy.
+
+## Operational notes
+
+- **Time accuracy**: cron precision on CF Workers is within ~15 seconds — adequate for routine triggering.
+- **No retry**: each `/fire` POST creates a new Claude Code session — retrying multiplies sessions and burns quota. The worker logs failures and moves on.
+- **Logs**: `wrangler tail` streams live; CF dashboard's "Logs" tab persists them per the observability tier.
+- **Cost**: scheduled handlers count against the Workers Free plan's 100k requests/day budget. 5 daily fires × 30 days = 150 requests/month — negligible.
+
+## Security
+
+- The token is **per-routine**: a leak only fires that one routine.
+- Secrets live in CF's encrypted secret store, never in the bundle, never in logs (verified by tests).
+- TLS to `api.anthropic.com` uses CF's standard cert verification.
+- `worker.js` has no `fetch` HTTP handler — the worker is unreachable from the public internet, only fires on cron tick.
