The agent's state/AGENTS.md stays the truth and its harness the only
writer. The harness mirrors the file into a new `agents-md` KV bucket,
and swarm-controller serves that copy, so a read works while the agent is
stopped. An edit is a unified diff plus the revision it was made against,
sent over the agent's existing control subject; the harness refuses a
stale base, applies the diff with `git apply --check` then `git apply` to
a temp copy, and writes the file only when both pass. Fixes#5519.
Files:
- swarm-queue-client/src/agents_md.rs, lib.rs: the bucket name and
subject, the mirror value, the `ApplyAgentsMd` control command and its
reply. `AgentControl` loses `Copy` because the new variant carries text.
- hive-agent/src/swarm_agents_md.rs, main.rs: the mirror task (start,
10 s re-read, immediate republish after an edit) and the apply.
- hive-agent/src/swarm_input.rs: the control loop answers both commands.
- hive-agent/src/claude_md_watch.rs: its AGENTS.md path is shared.
- hive-agent/Cargo.toml, Cargo.lock: sha1 for the git blob id (already in
the lock), tempfile moves from dev to runtime for the apply directory.
- swarm-controller/src/agents_md.rs, main.rs: the bucket reader and
GET/PUT /api/agents/{name}/agents-md; test AppState literals get the
new field.
- swarm-controller/src/agent_control.rs: the sink hands back raw reply
bytes, so each command decodes its own reply type.
- swarm-controller-api/src/agents_md.rs: the route bodies, shared with
swarmctl.
- swarmctl/src/agents_md.rs, main.rs: `swarmctl agent agents-md get|apply`.
- nix/host-modules/swarm-nats.nix, nix/module-eval/nats-authelia.nix: the
agent's publish grant on its own `$KV.agents-md.<agent>` key.
git needs no new package: agent containers enable programs.git, and the
harness unit's PATH includes /run/current-system/sw.
Claude Code (>= 2.1.277) and opencode both read AGENTS.md, but Claude
Code reads it only when no CLAUDE.md exists in its cwd or above. So
this is a plain rename with no CLAUDE.md stub left behind.
- hive-agent/src/agents_md_migrate.rs: new. At harness start, before
the first turn, renames state/CLAUDE.md to state/AGENTS.md when only
the former exists; logs an error naming both paths when both exist
and touches neither; does nothing otherwise. Idempotent.
- hive-agent/src/main.rs: calls it in serve_main; checkpoint prompt
and a comment name AGENTS.md.
- hive-agent/src/claude_md_watch.rs: the size watch reads AGENTS.md;
todo text, doc comments and tests follow. Module name, todo
subsystem key ("claude_md") and metric name
(hyperhive.agent.claude_md.lines) are unchanged so existing todo
rows and dashboard history carry over.
- hive-agent/src/turn.rs, hive-agent/prompts/system.md: prompts tell
the agent its file is AGENTS.md.
- hive-agent/src/{otel_turn_metrics,stats}.rs,
frontend/packages/agent/src/stats.js, hive-subagent-mcp/src/*.rs:
comments and a tool parameter description naming the agent's file.
- nix/host-modules/swarm-grafana/dashboards/agents.json: panel title
and description.
- claude-plugins skills claude-subagents, state-hygiene: they mean the
agent's own state file.
- CLAUDE.md -> AGENTS.md at the repo root; docs/crates/README.md link
(checked by check-doc-refs.sh), hive-c0re/README.md,
.prettierignore and the nix/sources.nix comment follow.
- docs/: every prose mention of the agent's file; persistence.md
documents the boot-time rename, claude-invocation.md the shadowing.
Fixes#5509
