What is runner-publish?

Instructions for maintaining and checking the workflow that generates and publishes Firebase Cloud Messaging host lists. They cover Go tests, local dry runs, DNS collection, GitHub Actions, SSH keys, and server deployment.

Testing or troubleshooting the Go command, validating DNS and connectivity, changing the scheduled GitHub Actions workflow, and deploying generated host files over SSH.

They provide repeatable checks and deployment rules for changing the generation pipeline without publishing invalid files or breaking the production update process.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00020	$0.00572
Opus 5	$0.00010	$0.00286
Sonnet 5	$0.00004	$0.00114
Haiku 4.5	$0.00002	$0.00057

Security

Grade A, and why

runner-publish scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 55 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Trigger

Modifying or validating FCM hosts update workflow (.github/workflows/main.yml).
Troubleshooting FCM hosts generation, publication, or server deployment failures.
Changing DNS query/validation logic and verifying behavior.

Entry Point

Workflow file: .github/workflows/main.yml
Go CLI entry: go run ./cmd/fcmhost run
Generated outputs: fcm_dual.hosts, fcm_ipv4.hosts, fcm_ipv6.hosts

Workflow

Local Verification

Before pushing any workflow or Go CLI updates:

Run test suite:
```
go test ./...
```
Dry run runner verification (checks FCM 5228 connectivity without dns harvest):
```
go run ./cmd/fcmhost run -workdir . -dns=false -v
```
Perform full local run to verify DNS harvesting and expansion:
```
go run ./cmd/fcmhost run -workdir .
```

GitHub Actions & Server Deployment

Workflow is scheduled 4 times daily (UTC 01:17, 07:17, 13:17, 19:17).
If manual refresh is needed, trigger via workflow_dispatch on GitHub Actions.
The workflow uses SSH Deploy Key ACTIONS_DEPLOY_KEY for checkout/push, and SERVER_SSH_KEY for deploying to /srv/cagedbird/fcm-hosts-next/ on the remote server.

Verification

Verify Go build and test status.
Check local generated fcm_dual.hosts, fcm_ipv4.hosts, fcm_ipv6.hosts files for correct format (IP host entries).

Check remote serving URL:

curl -sI https://fcm-hosts.cagedbird.cn/fcm_dual.hosts

Guardrails

Prefer SSH Checkout over HTTPS: To prevent GnuTLS connection timeouts on mainland dual-stack runners, workflow checkout and push MUST use the SSH deploy key (ACTIONS_DEPLOY_KEY).
Prevent Workflow Loop: Commits generated by the bot MUST include [skip ci] in the message and the push event must be configured to skip triggering another run.
Separate Keys: GitHub actions push key (ACTIONS_DEPLOY_KEY) and server deploy key (SERVER_SSH_KEY) are separate credentials. Do not mix them.
No Direct Remote Edits: Do not edit served host files directly on the server. Always update locally/via workflow.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

runner-publish is a skill published in the GitHub repository cagedbird043/fcm-hosts-next (57 stars, last pushed today), licensed MIT. It adds 20 tokens to every session and 572 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
