/usage-pause

Pause on purpose before a usage limit kills in-flight work. The skill reads the 5-hour session window's reset time and remaining headroom, breaks the wait into ScheduleWakeup stages, keeps every agent context warm through the pause with checkpoint pings, and hands control back after the reset.

Step 1 — resolve the usage window

Run the bundled resolver:

python "${CLAUDE_SKILL_DIR}/scripts/resolve_usage_window.py"

With an argument (/usage-pause 10:20pm, /usage-pause 74m), skip the probe and pass it through:

python "${CLAUDE_SKILL_DIR}/scripts/resolve_usage_window.py" --override "10:20pm"

On exit 0 the script prints one JSON object:

Field	Meaning
source	probe or override
reset_at	When the 5-hour window resets (ISO-8601, local zone)
seconds_until_reset	The wait the stage plan covers
stages_seconds	The ScheduleWakeup stage durations, in firing order
session_utilization	Percent of the 5-hour window spent (null on override)
weekly_utilization	Percent of the weekly window spent (null on override)
weekly_resets_at	When the weekly window resets (null on override)
weekly_near_cap	True when the weekly meter is at or past the warn threshold

On exit 2 the script prints {"error": ...}. Ask the user for a manual reset time via AskUserQuestion (offer clock-time and duration examples), then rerun with --override.

Probe mechanism

scripts/resolve_usage_window.py is the source of truth for live probe behavior. Endpoint URL, header names/values, credential path and token keys, response bucket keys, stage sizing, and the weekly warn threshold all live in scripts/usage_pause_constants/resolve_usage_window_constants.py — read those modules for the current values; do not restate them here.

In short: the resolver picks a bearer token, probes the OAuth usage endpoint the interactive /usage panel uses, and returns the session and weekly buckets with utilization and reset times. Token sources depend on the host:

• Desktop host (the CLAUDE_CODE_ENTRYPOINT variable is claude-desktop): the resolver does not read the CLI credential file, which belongs to a different authentication session than the one the desktop app counts usage against. It uses the session ingress token when one is set, and otherwise takes the manual-override path.
• Every other host: the resolver reads the Claude Code CLI's stored OAuth access token first (honored only while unexpired), then the session ingress bearer token file named by CLAUDE_SESSION_INGRESS_TOKEN_FILE (cloud sessions) when the credential token is unavailable.

Fallbacks, in order: both token sources unavailable (expired/unreadable credential and no ingress file), a failed request, or a response with no readable session-window reset time all end in exit 2 — the manual-override ask above. The manual path works with no probe at all, so the skill functions even when both token sources are unavailable.

Why this probe and not the others:

• The interactive /usage panel shows the same data but has no scriptable output.
• claude -p --output-format json spends usage to answer and its metadata reports per-call token counts, not the account window clock.
• anthropic-ratelimit-* response headers cover API-key Messages traffic, not the subscription session window, and reading them also costs a request.
• Refreshing the OAuth token from a script is out of scope: token rotation would desync the refresh token the CLI has on disk and log the CLI out. The resolver only ever reads tokens (credential file or session ingress file).

Weekly limit guard

When weekly_near_cap is true, WARN the user — report weekly_utilization and weekly_resets_at — and stop. No pause choreography runs around the weekly limit; waiting out a weekly window is its own later build.

Step 2 — the pause chain

Before the first sleep:

1. List active recurring loops (CronList). Record each one's schedule and prompt, then cancel it (CronDelete). Carry the recorded list inside the wakeup prompts so the state survives every stage.
2. Schedule the first stage with ScheduleWakeup, using the first duration in stages_seconds and the stage prompt template below.

The stage plan (stages_seconds from the resolver) keeps every stage under the maximum stage length and ends with a short tail so the final firing lands just past the reset. Stage sizing constants live in scripts/usage_pause_constants/resolve_usage_window_constants.py; a leftover too short to stand alone folds into the tail.

Every wakeup does exactly three things — ping, record, schedule — and dispatches no new work. The cache rationale: an unpinged idle agent left past the cache window resumes cold and re-reads its whole transcript, so pings run tighter than the cache lifetime and keep each agent's next real invocation cheap.

Stage wakeup prompt template

/usage-pause stage <stage_number> of <stage_total>: pausing until <reset_time_local>.
Remaining chain (seconds): <remaining_stage_durations>. Cancelled crons: <cancelled_crons_json>.
1. Ping every live agent AND every idle-but-warm agent with exactly this one line:
   "status checkpoint: reply with where you stand, do not start new work"
   An unpinged idle agent past the cache window resumes cold and re-reads its whole
   transcript; the ping keeps its next real invocation cheap.
2. Record any finished agent results on the task list. Dispatch nothing.
3. Take the first duration off the remaining chain and ScheduleWakeup it, passing this
   same prompt with that duration removed and the stage number advanced. When the
   remaining chain is empty, schedule nothing further and treat the next firing as final.

Final wakeup prompt template

/usage-pause final stage: the 5-hour window reset at <reset_time_local>.
1. Ping every live and idle-but-warm agent with exactly:
   "status checkpoint: reply with where you stand, do not start new work"
2. Record any finished agent results on the task list.
3. Restore every cron in <cancelled_crons_json>: CronCreate each one with its recorded
   schedule and prompt.
4. Hand control back to normal orchestration and resume work from the task list.

Fill each <slot> at schedule time: <remaining_stage_durations> is the tail of stages_seconds after the stage being scheduled, and <cancelled_crons_json> is the recorded cron list from pause time, carried verbatim through every stage.

Gotchas

• The stored access token lives about 8 hours and the CLI rewrites it on its own schedule, so a mid-afternoon probe can find it expired even while the CLI itself still works. That is the designed exit-2 path: give a manual time.
• On the desktop host the resolver never reads the CLI credential file, because that credential is a different authentication session than the one the desktop app counts usage against. With no session ingress token set, the desktop host takes the manual path: read the reset time from the interactive /usage panel and pass it, for example /usage-pause 10:20pm.
