/hq-cowork-secrets — Use HQ secrets from a sandboxed agent

Runs commands with HQ secrets injected, and lists secret names, from inside Cowork — where the hq CLI and ~/.hq vault are unreachable. Routes through the host-side MCP server. The server never returns a secret value itself, and the secret-injecting tool refuses to run a shell or value-printing binary — but these tools run host commands with your privileges, so treat them as host-trusted, not an airtight boundary.

Args: $ARGUMENTS — list (+ optional company/prefix) or exec (keys + command). Infer from intent if not explicit.

Two modes

List names — mcp__hq__hq_secrets_list

Shows secret NAMES and path-based nested names. Values are never returned.

{ "company": "<slug>", "personal": false, "prefix": "DEV" }

Omit company to use the active company; set personal: true for the caller's personal vault; prefix filters by path segment.

Run with secrets — mcp__hq__hq_secrets_exec

Injects named secrets as env vars of the same name into a child process and returns only the command's stdout/stderr.

{
  "keys": ["STRIPE_KEY", "DB_URL"],
  "cmd": ["./scripts/migrate.sh"],
  "company": "<slug>",
  "personal": false
}

cmd is argv (argv0 + args), NOT a shell string. The tool REFUSES to launch a shell or a raw value-printing binary as cmd[0] (sh/bash/zsh, printenv, env, echo, printf, cat, tee, node/python/perl/ruby, base64, xxd, strings, …) — this is defense-in-depth so an injected one-liner can't echo an injected secret back through the tool result. Invoke the actual consumer binary directly (e.g. vercel, aws, gh, or a deploy script). This is not airtight: a custom binary you control could still observe a secret it was given, so treat the tool as host-trusted.

Security rules (hard — from HQ core)

• No value-revealing path exists by design. hq secrets get --reveal is NOT wrapped. Do not attempt to capture a value by echoing the env var.
• Cross-company isolation. Pass company explicitly when crossing contexts. If the scoped secret is missing or the command fails on auth, STOP and ask — never retry against a different company's vault.
• Never paste secrets inline. Always consume via hq_secrets_exec injection; never ask the user to paste a value into chat.

When to use this instead of /hq-secrets

Only inside Cowork or another sandboxed plugin host. On a host-side session, prefer the unprefixed /hq-secrets (or hq run / hq secrets exec).

Why this skill exists

hq secrets exec reads the encrypted vault under ~/.hq with the user's Cognito session — neither is visible from Cowork's Linux VM. The host-side MCP server runs the real command on the host and returns only the child's output. The server never returns a secret value itself, and refuses to run a shell / value-printing binary — but it runs host commands with your privileges, so it is host-trusted, not a cryptographic boundary.
