Cli

official/cli skill

You're an AI controlling a glyph server through its CLI. This skill is a map of the entire glyph command surface plus the conventions that aren't obvious from --help — most importantly the workspace-scoping discipline that keeps your commands from racing with other clients, and the exit-code / error-code discipline that lets you branch mechanically on failures.

Setup

glyph injects what you need into your env when it spawns your task or session:

• GLYPH_SERVER — server URL (the CLI uses this automatically)
• GLYPH_WORKSPACE — workspace UUID (workspace-scoped commands inherit it)

Quick verification:

glyph health         # exit 0 ⇒ CLI works + server reachable
glyph workspace current --json | jq   # confirm workspace resolved

Command surface at a glance

Every workspace-scoped command inherits --server / --workspace-id / --output / --json and follows the shared exit-code table below. The subcommand groups:

Group	Purpose	Reference
workspace	Create / list / show / update / remove / reload workspaces; print current id	references/commands.md#workspace
session	Manage interactive sessions (list / new / show / rm / spawn a terminal)	references/commands.md#session
task	Dispatch one-shot tasks, list (incl. scoped by --origin), inspect them, tail activity, cancel, remove	references/commands.md#task
schedule	Cron-triggered task launchers (create / list / patch / enable / disable / run / preview / list-tasks)	references/commands.md#schedule
catalog	Install / sync / enable / disable agents, skills, MCPs	references/commands.md#catalog
workflow	Seed a workflow, read/mutate its live DAG (expand, patch a not_started node's spec via update-spec), respond to human nodes, terminate	references/commands.md#workflow
runtime	List registered runtimes (copilot, etc)	references/commands.md#runtime
Server inspection	health, config, status, logs — no lifecycle	references/commands.md#server-inspection
Server lifecycle	serve / start / stop / restart — out of scope for this skill	—

Workspace discipline

Every workspace-scoped command requires an explicit selector. The CLI reads GLYPH_WORKSPACE from your env (already set), so commands work as-is:

glyph task dispatch --agent writer --brief "..."

To act on a different workspace, pass --workspace-id <id> per command:

glyph task list --workspace-id ws-Y

The CLI does not consult any server-side shared "current workspace" state — selectors are process-local, immune to interference from other clients (other CLI sessions, dashboard tabs, AI agents on the same server).

Output discipline

• For parsing, always pass --json. Human/table format is not a stable contract — column order and headings change between releases.
• For streaming activity, pipe through jq -c to keep one event per line.
• Every --json shape you're likely to consume is documented in references/json-shapes.md. Consult it before writing a jq filter — most shapes have optional fields (present when the underlying row is non-null) that you should key off of.

Error discipline

Errors on stderr always carry a code:

agent "writer" is not ready: prereqs not acknowledged (HTTP 409, EntryNotReadyError)
  agent: acme/writer
  cause: prereqs not acknowledged
  fix:   glyph catalog agent ack-prereqs acme/writer

The fix: line is your next command, verbatim. The full code catalogue (all error names + typical HTTP + remediation) lives in references/error-codes.md. In particular:

• EntryNotReadyError is the single most common branch you'll take — it carries a structured reason describing whether the agent needs ack-prereqs, is disabled, has missingDeps, or has blockedDeps (which recurse). The reason table is in references/error-codes.md#entrynotreadyerror-reasons.

Exit codes

code	meaning	what to do
0	success	continue
1	generic error (incl. missing workspace)	read stderr; usually missing flag/env
2	usage error (missing required flag, removed subcommand)	fix the invocation; do not retry as-is
3	server unreachable	ask user to glyph start or check --server
4	server returned 4xx/5xx	read code in stderr; consult references/error-codes.md

Exit code 2 means "the command itself is wrong" — never retry it without changing the invocation. Exit code 4 means "the server rejected this" — read the code field, it tells you the next move.

Pitfalls

• To wait for a task, use glyph task activity <tid> --follow (real-time SSE). Polling task list in a shell loop wastes cycles and lags real events.
• For a one-shot "what's happened so far?" snapshot, drop --follow — glyph task activity <tid> --json returns the current activity plus totalItems in one call. --follow blocks until the task terminates.
• Terminate before you remove. Plain task rm <tid> requires the task to be in a terminal state (succeeded / failed / cancelled); if it's still running, glyph task cancel <tid> first, then task rm. Reach for --purge only when you also want the workdir + runtime state gone (post-mortem stderr.log is lost). Same distinction on session rm and workspace rm.
• Always resume --follow with the printed last seq:. On every clean exit (event: end or stream closed) AND on mid-stream-error exit, the CLI prints last seq: <N> to stderr — pass --after <N> on the next --follow invocation to resume without gaps or duplicates. Ctrl+C is the exception (stderr is not flushed); derive the seq from the last stdout NDJSON item instead (... | tail -1 | jq .seq). Full resume playbook lives in references/playbooks.md#monitor-a-long-running-task.
• Always get workspace ids from glyph workspace list --json | jq. Dashboard URL fragments drift between releases and aren't a wire contract.
• schedule patch is sparse — only the flags you pass go on the wire. To remove a field, pass --clear-details / --clear-runtime (an empty --details "" is treated as omitted, not as clear).

References (mandatory reading before non-trivial work)

• references/commands.md — per-group subcommand reference (workspace / session / task / schedule / catalog / workflow / runtime / server inspection). Skim once, keep as lookup.
• references/playbooks.md — multi-step goal-oriented playbooks (install-and-verify agent, dispatch-and-wait, monitor task, sync entry, clean up, onboard fresh workspace, create a local agent on the fly).
• references/json-shapes.md — the common --json payload shapes with concrete field lists and optionality notes.
• references/error-codes.md — every code value the server emits + the matching glyph command to fix it.
