🔄 Topic

Aider stopped being installed a while ago, but the stack was still quietly shelling out to it. Retiring the lane properly, and adding a rule that agents must commit their own work before finishing, closed two different kinds of loose ends.

🎯 Goal

Stop a dead tool from being routed to silently, and stop agent work from ending in a state nobody can find without asking.

🛠 What I Did

I closed out one decommissioned tool and one process gap in the same pass.

Main areas covered:

  • found the AI-OS orchestrator still had an aider_local lane that shelled out to a binary no longer installed on the machine — a routing path pointing at nothing, silently failing whenever selected
  • retired the lane properly instead of leaving it to fail: removed the shell-out path, marked Aider retired in the documentation, and corrected three other stale operational claims the same audit surfaced
  • added a Stop hook that reports any outstanding, uncommitted git work when an agent finishes a task — visibility instead of trusting that “done” means “landed”
  • documented a new rule: agents must land their own work in git before declaring a task finished, rather than leaving changes staged, uncommitted, or scattered across a worktree for someone else to notice later
  • rotated resolved skill observations into an archive as part of the same cleanup, so the active observation log reflects only what is still open

🔗 Key Cybersecurity Connections

A routing lane pointing at an uninstalled binary is the software equivalent of a stale firewall rule referencing a decommissioned host — harmless until something tries to use it, then a confusing failure with no obvious cause. Retiring it properly, with documentation corrected alongside the code, is what separates decommissioning from just letting something rot.

The “land your own work” rule is a change-control basic applied to autonomous agents: work that exists only as uncommitted state is work that does not exist as far as provenance, review, or recovery are concerned. Making that visible by default, rather than trusting each agent to remember, is the difference between a policy and a hope.

🔍 Investigation Questions

  • Are there other routing lanes pointing at tools no longer installed?
  • Does documentation get corrected in the same pass as the code that made it stale?
  • Can agent work end in an uncommitted state without anyone noticing?
  • Is “task finished” ever declared while git state is dirty?
  • Are resolved observations kept separate from the active backlog, or left to accumulate?

🚨 Detection Opportunities

Checks for decommissioning and work-landing hygiene:

  • a routing lane referencing a binary or service no longer present
  • documentation describing a retired tool as still active
  • a task marked finished with uncommitted changes in its worktree
  • the Stop hook firing and being ignored rather than acted on
  • an observation log with resolved entries mixed indefinitely into the active list

Example:

project=ai-os-lane-retirement
signal=lane_references_uninstalled_binary
risk_area=stale_routing_configuration
triage=audit_all_lanes_against_currently_installed_tools

🧭 MITRE ATT&CK Techniques

No direct mapping claimed. This is decommissioning hygiene and change-control discipline for autonomous tooling.

⚠ Challenges

The Aider lane had been silently dead for a while — nothing alerted on it because failure only happens when something is routed there, and evidently nothing had been recently. Silent failure paths are exactly the ones that need active auditing rather than waiting for a complaint.

📚 What I Learned

I learned that decommissioning has two halves people often finish only one of: removing the broken path, and correcting everything that still describes it as working. Doing both in the same pass is what actually closes the loop.

➡ Next Steps

  • Audit remaining lanes against what is actually installed
  • Keep the Stop hook’s outstanding-work check as a hard gate, not just a report
  • Continue rotating resolved observations on a schedule
  • Extend the “land your own work” rule to any new agent lane added going forward

🧠 Reflection

Neither fix was exciting, and both were the kind of hygiene that prevents a confusing debugging session six weeks from now, for a future me who has forgotten this ever happened.

🧩 Lessons Learned

What worked

Retiring the dead lane and correcting its documentation in one pass, and making uncommitted work visible by default.

What broke

A routing lane silently pointed at an uninstalled tool, and agent work could previously end without landing anywhere.

Why it broke

Decommissioning had removed the tool but not the path to it, and nothing enforced that finished meant committed.

Fix / takeaway

Decommission code and documentation together, and make “land your own work” a checked rule, not an assumption.

📈 Skill Progression Context

This supports my cybersecurity progression because stale configuration, incomplete decommissioning, and unenforced process rules are exactly the small gaps that accumulate into real incidents in production environments.

😄 TL;DR

Retired a dead tool properly, and made sure agents can’t call a task done while their work is still lying around uncommitted.
