AGENT_LOOP.md

Agent Loop

Some Issues in this repo are worked by an automated agent loop, not a human. The harness is dkackman/harnest; its ticket protocol is the full rule set this page summarizes, and lib/classify.jq there is the authoritative map from labels to the session that acts next. Nothing about running the loop lives here. This page is for anyone, human or agent, who opens or comments on one of its Issues.

The two roles

• Implementer: has this repo checked out and SSH access to the box running the MCP server. Triages, reproduces, fixes, deploys and hands the ticket back. Never verifies its own fix.
• Tester: talks to the MCP server only as a protocol client, with no source checkout and no shell on the server box. It re-runs the original repro over MCP and either confirms the fix or bounces the ticket.

The only role that can mark an issue verified is the one that cannot patch around a bug. Preserve that: do not fix and verify the same ticket yourself.

Other sessions in the harness:

• Lead (owner:lead): designs a feature with Don, turns an idea into a feature or a single fix, or closes it.
• Docs reviewer: read-only; closes a docs-review ticket.
• Regression agent: runs the scripted MCP suites (regression-suite-*.md in harnest) against the live server and files regression and performance issues. It takes no part in the implementer/tester hand-off.

Outside filings

The loop runs as the repo owner's GitHub login and must not act unattended on text anyone else filed in this public repo. An issue from another login, including a field-report from someone else's session, is relabelled owner:don + status:needs-approval before any role works it, and reaches the loop only if the maintainer hands it back.

Security findings are never public issues. A boundary that did not hold (a gate, a path, a URL, a disclosure, a destructive call without acknowledgement) goes to a draft GitHub security advisory. No agent may add the security label.

Reading a ticket

Tickets use the MCP agent-loop ticket issue template (ideas use MCP agent-loop idea). Two label families carry the state; check both before acting.

owner:* is exactly one of owner:implementer, owner:tester, owner:lead or owner:don: whoever acts next. If it is not you, leave the issue alone beyond reading it. The owner label is the only signal: a status addressed to Don is stale once he swaps the owner back.

status:* is where the ticket is:

Label	Meaning
(none)	Open, ready for the implementer to reproduce
status:fixed-pending-verify	Fixed and deployed; the tester re-runs the repro over MCP
status:verified	The tester confirmed the fix over MCP; closed as completed
status:reviewed	A docs-review fix closed by the docs reviewer (never status:verified)
status:needs-info	A question bounce; whoever is asked answers before work continues
status:needs-approval	With owner:don: parked for the human, after a written proposal. Required for engine or syntax changes and anything breaking beyond a rename. Neither agent touches it
status:plan-review	A feature plan is posted and waiting for Don
status:plan-approved	Don approved the plan. Only Don adds it
status:needs-spec	The tester writes acceptance cases for the plan's stages

Labels that close a ticket without a fix:

• wontfix: the implementer's call, with a reason in a comment; closed as not planned. The tester may reopen once with new evidence; a second wontfix is final.
• duplicate: closed as not planned with duplicate of #NN in a comment. Closed issues count for duplicate detection (gh issue list --state all). A verified issue that reproduces again is not a duplicate: it becomes a new regression issue (regression of #NN), and nobody reopens the old one.

Other labels:

Label	Meaning
docs-review	A fix to text neither the server nor the plugin serves; the docs reviewer verifies it instead of the tester
breaking-change	The fix changed the MCP interface; the tester adjusts its calls rather than filing a new bug
field-report	Filed from Don's own dw sessions, not the harness
regression, performance	Filed by the regression agent
idea	An idea for the lead to assess
feature, stage	Work designed with Don and built in stages; a stage is a child issue of one feature
lane:batch	A plan review with no question of a kind Don decides, approved in a batch
parked	Deferred: on owner:lead, until every blocking issue closes; on owner:don, Don's
release, release-blocker	While an open release issue exists, only release-blocker issues move
stabilization, arch-approved	dw's stabilization freeze (in force while docs/stabilization/FREEZE exists on develop): work parked for it, and new surface Don approved during it
arch-review	A hand-off waiting on the architecture reviewer, who checks it against docs/ARCHITECTURE.md and passes or bounces it
consolidation	Filed weekly from scripts/arch_report.py; Don plans it (to owner:lead) or closes it
backend:shared, backend:cuda, backend:mps	What the bug is about
target:lem, target:mini-ai, target:minid, target:local	Which server's loop claims it; a non-lem target is for Don to triage
verified-on:mps	Verified on the Mac only; CUDA has not re-verified the fix
priority:2, priority:3	Backlog rank

If you want to participate

• Only touch an issue owned by you (or, for a human, one parked with owner:don).
• To hand a ticket on, swap the owner:* label and say what you did in a comment. The next actor has no memory of your session, only the thread.
• Keep implementer and tester separate. Only the tester (or an equally independent verifier) closes an issue as completed with status:verified, and only after a real MCP call shows the fix, not by reading the diff. The one exception is docs-review.
• Reference the issue in the commit that fixes it, with a scope (fix(mcp): #42 - ...), on a branch merged to develop, never master.
