Tools change faster than your agent’s training data.

We scan the changelogs of 89 tools a few times a day and keep the changes that would alter your agent’s next action: 1578 since January 2026, each linked to its source.

An agent couldn’t merge a stacked PR, so it merged by hand and closed the PR for good. gh stack merge does it in one command. It wasn’t in the agent’s training data. Read the session →

render ea sandboxes create adds HTTPS egress allow-list option

When creating a sandbox that needs outbound HTTPS access to specific domains, run `render ea sandboxes create --allow-egress-https <domain>` and repeat the flag for each domain. If no network policy is specified, this sets the `allow-list` policy.

Local Explorer invokes a Worker scheduled() handler during local development

When testing `scheduled()` locally, start a development server and use Local Explorer’s Cron Triggers page or API to invoke a configured or ad hoc cron expression, then inspect the result. Full logs and traces are available in the Worker’s owning development session when Observability is enabled.

curl -X POST "http://localhost:8787/cdn-cgi/local/explorer/api/local/scheduled?worker=<worker-name>" -H "Content-Type: application/json" --data '{"cron":"0 * * * *","scheduled_time":1745856238000}'

helmfile `dir=` selector filters releases and skips sub-helmfile traversal

When syncing a service in nested Helmfiles, run `helmfile -l dir=<path> sync` to select releases whose defining Helmfile is in that directory or a subdirectory; Helmfile skips sub-Helmfile branches whose location rules out a match.

helmfile -l dir=apps/<single-service> sync

helmfile kubedog startup-only pod logs

When tracking a release with kubedog and routine logs enabled, set `trackLogsUntilReady: true` or pass the documented flags to `helmfile apply`. Each pod’s routine logs stop after its first Ready transition while readiness and failure tracking continue.

helmfile per-release `trackLogsInterval`

When using Kubedog tracking with `trackLogs` or `trackFailedLogs` on `helmfile apply` or `helmfile sync`, set `trackLogsInterval` on the release to control log update frequency. An explicitly supplied `--track-logs-interval` overrides it; otherwise it overrides the `10s` default (minimum `1s`).

releases: - name: <release> chart: <chart> trackMode: kubedog trackLogs: true trackLogsInterval: 1s

To read a result as Markdown, select its URL with `jq` and request it with `curl` using `Accept: text/markdown`.
