sdlc-stop

A command for safely stopping an AgentFlow software pipeline, including its active work groups when used as a plugin.

In plain words
What is it for?
Use it to shut down a running pipeline, notify workers, clean up unfinished assignments, and remove related temporary workspaces.
Why use it?
It pauses new work, lets active tasks finish, and returns tasks that have not started to the backlog so the workflow can be resumed cleanly.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sdlc-stop scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 84 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/sdlc-stop

Gracefully shut down the AgentFlow pipeline.

Plugin Mode Additions

In plugin mode, also:

  1. Call TeamDelete("sprint-team") to clean up the agent team
  2. Workers receive shutdown signal via SendMessage (faster than Asana read)
  3. No need to instruct user about crontab — plugin handles scheduling

Process

Step 1: Signal pausing

Find the pinned Status task across all [SDLC] projects.

Post comment: [SYSTEM:PAUSING] Graceful shutdown initiated. Active workers will finish their current stage. No new tasks will be dispatched.

Step 2: Drain active work

Check all tasks in Research/Build/Review/Test/Integrate stages:

For tasks with [BUILD:STARTED] and recent heartbeat (< 10 min):

  • Leave them alone — the worker is still active
  • Report: "Waiting for <task_code> to finish (worker )"

For tasks in Research or Build WITHOUT [BUILD:STARTED] (not started yet):

  • Move back to "1 - Backlog"
  • Clear slot: [SLOT:T<N>][SLOT:--]
  • Reset stage: [STAGE:X][STAGE:Backlog]
  • Clean up git worktree if it exists: git worktree remove feat/<task-code>-<slug> --force

For tasks in Review/Test that are waiting (no worker actively processing):

  • Move back to "1 - Backlog"
  • Clear slot
  • Reset stage
  • Clean up git worktree if it exists: git worktree remove feat/<task-code>-<slug> --force

Step 3: Wait for active workers

Report which tasks are still being worked on.

Tell the user: "Active workers are finishing. The system will be fully paused when all active work completes. You can check your Kanban board for current status."

Step 4: Post paused status

Update the Status task:

[SYSTEM:PAUSED]

Graceful shutdown complete — <timestamp>
Tasks returned to Backlog: <N>
Tasks still completing: <N> (if any workers were mid-build)

To resume: run /sdlc-orchestrate

Step 5: Disable crontab (instruct user)

Tell the user:

To fully stop the orchestrator, comment out or remove the crontab entry:

  crontab -e
  # Comment out: */15 * * * * /usr/local/bin/claude -p "Run /sdlc-orchestrate" ...

To resume later, uncomment it and run /sdlc-orchestrate once to kick things off.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

sdlc-stop is a skill published in the GitHub repository UrRhb/agentflow (4 stars, last pushed 5mo ago), licensed MIT. It adds 32 tokens to every session and 725 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
