Re-enter long-running Plans.md execution with fresh context
A meta-skill that combines /loop (CC dynamic mode) with ScheduleWakeup to re-enter long-running tasks with fresh context on each wake-up.
Calls harness-work --breezing via Agent on each wake-up,
constructing a re-enterable loop where 1 cycle = 1 task completion.
Long-session helpers (CC 2.1.108+):
When you return, run /recap to get a fresh summary before checking /harness-loop status.
For operations with long absences or frequent re-entries, prioritize ENABLE_PROMPT_CACHING_1H=1.
Long session recommendation (CC 2.1.108+):
When the session is expected to exceed 30 minutes, run bash "${HARNESS_PLUGIN_ROOT}/scripts/enable-1h-cache.sh" after resolving the plugin bundle root to opt in to 1-hour prompt caching.
Codex 0.123.0 automatic bug fix inheritance:
Manual shell follow-up queue and /copy after rollback are automatically inherited as Codex TUI fixes.
The loop runner does not add additional input queues, copy wrappers, or rollback workarounds.
Queueing when manual shell follow-ups are sent during long-running work is left to the Codex runtime.
Quick Reference
Input
Action
/harness-loop all
Loop through all incomplete tasks (default: max 8 cycles)
/harness-loop all --max-cycles 3
Stop after 3 cycles
/harness-loop 41.1-41.3 --pacing ci
Execute task range with CI pacing
/harness-loop all --plan roadmap
Loop through the roadmap named Plans
/harness-loop all --pacing night
Overnight batch (3600s interval)
/harness-loop status
Check status of running runner
/harness-loop stop
Request stop of running runner
Options
Option
Description
Default
all
Target all incomplete tasks
-
N-M
Specify task number range
-
--plan NAME
Use named plan from plans/manifest.json
active/default
--max-cycles N
Maximum number of cycles
8
--pacing <mode>
Wake-up interval mode
worker (270s)
Pacing value mapping
pacing
delaySeconds
Use
worker
270
Right after Worker completion (cache warm within 5 min)
ci
270
Short CI job wait
plateau
1200
20 min (retry interval after plateau detection)
night
3600
Extended overnight leave
Constraint: ScheduleWakeup's delaySeconds is clamped to [60, 3600] at runtime.
worker / ci at 270s and night at 3600s are within this range.
plateau at 1200s is also within range. When specifying directly, always use 60 or above and 3600 or below.
harness-loop calls helper scripts under the plugin bundle root, not the host project's cwd.
Think of it as separating the workbench (host project) from the toolbox (plugin bundle).
At the start of each wake-up, determine HARNESS_PLUGIN_ROOT in this order:
Use CLAUDE_PLUGIN_ROOT if it is present and contains scripts/
If CLAUDE_PLUGIN_ROOT is absent, reverse-calculate the plugin bundle root from CLAUDE_SKILL_DIR
${CLAUDE_SKILL_DIR}/../.. for skills/harness-loop distribution
${CLAUDE_SKILL_DIR}/../../.. for .agents/skills/harness-loop mirror distribution
If neither resolves, stop and re-run after setting CLAUDE_PLUGIN_ROOT to the plugin bundle root
Keep Plans.md and .claude/state/... on the host project side.
Only call helper scripts from ${HARNESS_PLUGIN_ROOT}/scripts/....
In repos with multiple Plans.md, specify --plan NAME explicitly at the start of a long run.
The runner retains the Plans file resolved at start time across cycles; do not switch the active plan mid-run.

│
▼
[Step 0] Resolve plugin bundle root to HARNESS_PLUGIN_ROOT
Use CLAUDE_PLUGIN_ROOT if valid
Otherwise reverse-calculate plugin bundle root from CLAUDE_SKILL_DIR
* Do not reference host project cwd's scripts/
│
▼
[Step 1] Read Plans.md first
Identify first cc:WIP / cc:TODO task (get task_id)
* No incomplete tasks → loop ends (normal completion)
│
▼
[Step 2] Check for and generate sprint-contract
Check for .claude/state/contracts/${task_id}.sprint-contract.json
If absent, generate with node "${HARNESS_PLUGIN_ROOT}/scripts/generate-sprint-contract.js" ${task_id}
Immediately after generation (first time only): bash "${HARNESS_PLUGIN_ROOT}/scripts/enrich-sprint-contract.sh" <contract-path> \
--check "Auto-approve on wake-up (harness-loop: confirm DoD from reviewer perspective)" \
--approve <- promote draft → approved
(Skip for existing contracts since they are already approved)
│
▼
[Step 3] Contract readiness check
bash "${HARNESS_PLUGIN_ROOT}/scripts/ensure-sprint-contract-ready.sh" <contract-path>
│
▼
[Step 4] Reload Resume pack
harness-mem resume-pack (re-inject context)
│
▼
[Step 4.5] Advisor consult (only when needed)
Consult before first execution of high-risk tasks / after 2nd failure with same cause / just before plateau
Build `advisor-request.v1` and consult
│
├── PLAN → prepend advice to next executor prompt
├── CORRECTION → re-execute as local fix instruction
└── STOP → stop loop immediately and record reason
│
▼
[Step 5] Execute one task cycle
worker_result = Agent(
subagent_type="claude-code-harness:worker", # worker agent (not harness-work)
prompt="Task: ${task_id}\nDoD: <extracted from Plans.md>\ncontract_path: ${CONTRACT_PATH}\nmode: breezing",
isolation="worktree",
run_in_background=false
)
# worker_result: { commit, branch, worktreePath, files_changed, summary }
│
▼
[Step 5.5] Lead review execution
diff_text = git show worker_result.commit
verdict = codex_exec_review(diff_text) or reviewer_agent_review(diff_text)
* See flow.md for details
│
▼
[Step 5.6] APPROVE → cherry-pick to main / REQUEST_CHANGES → correction loop (max_iterations from contract, default 3)
APPROVE: git cherry-pick → update Plans.md to cc:done [{hash}] → delete feature branch
Still rejected after MAX_REVIEWS: escalation
* See flow.md for details
│
▼
[Step 6] Plateau determination
bash "${HARNESS_PLUGIN_ROOT}/scripts/detect-review-plateau.sh" ${current_task_id}
│
├── PIVOT_REQUIRED (exit 2) → stop loop + user escalation
├── INSUFFICIENT_DATA (exit 1) → continue
└── PIVOT_NOT_REQUIRED (exit 0) → continue
│
▼
[Step 7] Cycle count check
│
├── cycles >= max_cycles → stop loop (limit reached)
│
▼
[Step 8] Record checkpoint
harness_mem_record_checkpoint(
session_id, title, content=cycle result summary
)
│
▼
[Step 9] Schedule next wake-up
ScheduleWakeup(
delaySeconds=<pacing value>,
prompt="/harness-loop <same args>",
reason="cycle {N}/{max} complete — proceeding to next task"
)
Cycle Stop Conditions
Condition
Stop type
Response
cycles >= max_cycles
Normal stop (limit reached)
Report to user
PIVOT_REQUIRED (exit 2)
Abnormal stop (escalation)
Ask user for decision
No incomplete tasks
Normal stop (all complete)
Output completion report
Stops after 3 cycles when --max-cycles 3 is specified.
Stops after 8 cycles by default (--max-cycles 8).
Interim Reports / Silence Policy
In long-running loops, interim reports are treated as "notifications when a decision changes" rather than "heartbeats for reassurance".
In environments where Codex 0.123.0 background agents can receive transcript deltas, do not respond merely because a delta arrived; maintain explicit silence when not needed.
Report:
Cycle complete, limit reached, all complete, blocked
When only transcript deltas increase and task / review / advisor state has not changed
When only fine-grained stdout in logs increases
During pacing wait between next wake-ups
Default is "1 final report per cycle".
However, unanswered Advisor requests, pending Reviewer results, and pre-plateau warnings take priority over the silence policy.
Integration with /loop
This skill is used in combination with CC's /loop (dynamic mode).
When /loop is enabled, CC continues autonomous re-entry execution,
and calls ScheduleWakeup at the end of each cycle to schedule the next wake-up.
/loop sentinel: <<autonomous-loop-dynamic>>
Each wake-up starts with fresh context, preventing context contamination from previous cycles.
Reloading the resume pack via harness-mem resume-pack is required (Step 2).
The main actor in this skill is the executor; the advisor is called only when needed.
Think of it as the responsible party running autonomously and consulting a veteran only for difficult parts.
Consultation conditions are fixed; natural-language "low confidence" judgments are not used.
