tfctl — HCP Terraform CLI

Single binary, full v2 API coverage. Already authenticated.

Hard rules

1. Never pipe tfctl JSON to an external jq. Use the built-in --jq '<expr>' flag — it implies --json and runs gojq on the response envelope.

2. Resolve names with -p, not separate lookup calls. Paths with {workspace}/{team}/{project}/{varset} accept -p workspace=NAME etc. — tfctl resolves name→ID for you. Don't fetch the ID first.

3. Trust the first answer. data: [], data: null, relationships.X.data: null, or stderr "no current run"/"not found" ARE the answer. Don't re-query in another format. Don't walk relationships "to verify".

4. When a named resource is not found, stop completely. Exit code 2 or absence from a listing IS the full answer. Never:

   • Try a different resource ID "to verify the endpoint works"
   • Pivot to another org/workspace that appeared in the available list
   • Explore related resources to find "similar" information
   • Use Rule 3 to justify switching to a different resource: if you listed orgs and 'platform' isn't there, the first answer is "platform doesn't exist" — stop, don't use whatever org IS listed instead.

   Examples: run-POLICY returns exit 2 → stop, don't query other run IDs. Listing orgs shows no 'platform' → stop, don't use the org that IS listed.

5. Never run tfctl harness exec yourself to self-authorize. The --allow-delete grant is a human's opt-in for your session. If a delete is refused, relay the printed harness exec --allow-delete=<class> command back to the human — do not run it (or set TFCTL_EXEC_SESSION) to grant yourself permission. See Deleting resources.

Deleting resources

Deletes are destructive, so tfctl itself gates them — you don't need to police this with a blanket refusal. A noninteractive tfctl ... -X DELETE only goes through when a human has opted in for this session by launching you via tfctl harness exec --allow-delete=<class> -- <command> (which sets TFCTL_EXEC_SESSION). Otherwise tfctl refuses on its own and tells you what to do.

So when you're asked to delete something, just run the normal command and let tfctl be the gate:

tfctl api PATH -X DELETE

• If the session authorizes that resource's class, it succeeds — that's the human's intent, not a violation; proceed and report the result.
• If it doesn't, tfctl refuses with a self-documenting message and prints the exact command to hand back (including the harness exec --allow-delete=<class> a human can use to authorize you). Relay that rather than forcing it; don't run harness exec yourself to self-authorize.
• You can't tell in advance whether the session grants a class — so don't guess. Attempt the delete and let the refusal tell you. The refusal is a plain exit 1 with a message naming the class and the --allow-delete=<class> command; that is your cue to relay. This is a grant gap, NOT an auth failure: never report it as an expired token, an exit code 3, or tell the human to re-login unless tfctl actually says the token is expired/invalid.
• Apply ordinary caution to irreversible deletes (organizations, projects): they are never covered by the reversible/all wildcards and must be granted by name. For a high-stakes target, confirm intent with the human first even when the session would allow it.

URL shape: per-workspace subpaths live at /workspaces/{workspace}/...

Most "things attached to a workspace" (vars, runs, varsets, remote-state-consumers, configuration-versions, notification-configurations, state-versions) are under /workspaces/{workspace}/..., NOT /organizations/{org}/workspaces/{name}/.... The org-nested form only exists for the workspace resource itself (/organizations/{org}/workspaces/{name}). For everything else, use /workspaces/{workspace}/X -p workspace=NAME.

Exception: Policy checks and run-specific data live under /runs/{run-id}/..., not under workspace paths. For example: /runs/{run-id}/policy-checks.

Anti-patterns to avoid

These paths do not exist; don't try them:

• ❌ /organizations/{org}/workspaces/{name}/vars — use /workspaces/{workspace}/vars -p workspace=NAME instead
• ❌ /organizations/{org}/workspaces/{name}/state-versions — use /workspaces/{workspace}/state-versions -p workspace=NAME
• ❌ /organizations/{org}/workspaces/{name}/configuration-versions — use /workspaces/{workspace}/configuration-versions -p workspace=NAME
• ❌ /workspaces/{workspace}/policy-checks — use /runs/{run-id}/policy-checks instead
• ❌ /organizations/{org}/varsets (partially wrong path) — use /organizations/{organization}/varsets with correct org placeholder
• ❌ External jq pipes like tfctl ... | jq '...' — always use tfctl api ... --jq '...' with built-in flag

Output flags

Need	Flag
Filter / extract	--jq '<expr>'
Full JSON	--json
Render for human	--markdown
Audit a mutation	--dry-run

--jq implies --json. Don't pass both. Always pass one explicitly — don't rely on auto-detect.

JSON:API conventions

Responses are JSON:API envelopes: {data: {id, type, attributes, relationships}} (or data: [...] for lists). To follow a link, read data.relationships.<name>.data which gives {id, type} or null. A null is final — there is no related resource.

Pagination: default page 1. Add --all for all pages (cap 2000), or --page-size N / --page-number N for explicit control. For counts, use --page-size 1 --jq '.meta.pagination.["total-count"]'.

Mutations & batch updates

# Create or update a single variable
tfctl api /workspaces/{workspace}/vars -p workspace=NAME -a key=VARKEY -a value=VALUE -a category=env

# Batch updates: use separate calls (HCP TFC doesn't support bulk POST for vars)
# Instead of trying /workspaces/{ws}/vars with multiple items, do:
tfctl api /workspaces/{workspace}/vars -p workspace=NAME -a key=VAR1 -a value=VAL1 -a category=env
tfctl api /workspaces/{workspace}/vars -p workspace=NAME -a key=VAR2 -a value=VAL2 -a category=env
# (Multiple calls cost more, but it's the supported pattern)

# PATCH with a raw body
tfctl api /workspaces/{workspace}/X -X PATCH -p workspace=NAME -i '{"data":{"type":"X","attributes":{…}}}'

Add --dry-run to preview without sending.

Exit codes (quick map)

Code	Meaning	Action
0	Success	Done
1	Informational message or usage error	Read stderr; if it says "no current run" or similar, that IS the answer — stop
2	Not found (workspace/run doesn't exist) OR invalid auth	Verify the ID/name is correct, then check token if still failing
3	Auth token expired or invalid	Re-authenticate
4	Network error	Retry after brief delay
5	Rate limited (429) or server error (5xx)	Retry with backoff
6	Resource has an error state	The error is already diagnosed in output (e.g., plan failed); read it

Important: When an API returns data: [] (empty list) or data: null, that IS the answer. Don't retry with different flags or endpoints.

Common troubleshooting

Symptom	Cause	Fix
exit 2 when listing workspaces	Organization doesn't exist or auth token has no access	Verify org name and re-authenticate
exit 1 with "no current run"	Workspace simply has no active run (informational)	This is the answer — stop, don't verify
exit 3 when making any API call	Auth token expired	Re-authenticate with tfctl login
exit 5 (429 rate limit)	Too many requests	Wait and retry; tfctl will backoff automatically
exit 6 with "plan is errored"	Terraform plan had syntax errors (not CLI error)	Read the plan output for details
Empty list (data: []) when filtering	No resources match criteria	Verify criteria is correct; empty list is valid answer

Smart defaults

• {organization} resolves from active profile if set.
• {workspace} resolves from a local cloud {} block in CWD.
• Already-formed IDs (ws-…, team-…, prj-…, varset-…) are passed through as-is.
