claude-bridge — project instructions

Bridge communication (enforced — read this first)

Canonical block. Everything down to §Layering is the portable bridge charter, copied verbatim into every project that mounts the bridge MCP. Keep it byte-identical with the template in the wiki (Use Cases → The portable CLAUDE.md block); improvements go to the template first, then out to each project. Anything specific to this repo lives under §Project addendum below, never inline above it.

Anything you measure in an addendum is perishable. Date it, give the command that re-measures it and what each outcome means, and tell the reader to delete the section once it stops reproducing. The four parts work together: deciding what would falsify a claim is the expensive step, and a reader in the middle of another task will not pay it, so a bare "verify before relying on this" costs the same space and does nothing. The case this is for is a note that goes stale as a live restriction — it will tell a future session it cannot do the thing at the moment doing it becomes the job.

If no fleet_* MCP tools are mounted in this session, this section does not apply — skip it.

fleetd is the sole communication gateway between agents here. The orchestrating session (the primary) and every delegated peer (a member) mount the same MCP server and talk only through its fleet_* tools. No session addresses a peer, a broker, or the network directly.

Which role am I? — settle this before acting

Every role reads this file. A member runs in a git worktree of this same repo, so it inherits this CLAUDE.md verbatim, and every rule below is role-conditional.

Call fleet_whoami. It returns primary, worker, or architect, resolved by the daemon from your connection — unforgeable, and the same resolution its authorization gate uses. A worker also carries its sessionId, profile, worktree and branch; an architect carries the slot name it was bound to. Don't infer what you can ask.

Only if that call is unavailable, fall back to these — each is one-way, so keep reading until one fires: the reply charter in your system prompt ("You are a spawned member in the claude-bridge fleet") ⇒ spawned member; fleet tools prefixed mcp__fleet__* ⇒ spawned member (the launcher fixes that mount name; a primary's mount is named by whoever wrote its .mcp.json, so it varies — and a member spawned before CB-632 still says mcp__bridge__*); ANTHROPIC_BASE_URL set ⇒ spawned member (Claude-model members run on a clean env, so its absence proves nothing). None of these separate a worker from an architect — only fleet_whoami does. Still unsure ⇒ act as a worker, the most restricted member role. The two mistakes are not symmetric: a primary acting as a worker is refused by the authorization gate — loud and self-correcting — while a member acting as the primary ends its turn with no fleet_reply, and the sender silently receives nothing. Fail toward the recoverable error.

Invariants — both roles, no exceptions

1. Never set, export, or forward ANTHROPIC_BASE_URL (or ANTHROPIC_AUTH_TOKEN). The primary stays on subscription; only the bridge puts a member off it, at spawn. Mounting the bridge must never move a session across that boundary.
2. The bridge is the only channel. Text you print in your terminal reaches nobody — the other side cannot see your screen. An answer that isn't in a fleet_* call is silently discarded.
3. Identity comes from the connection, never an argument. Workers never pass a target; you cannot act as another session. Spawn/stop/drain are lead-only; send is lead or architect; reply/ask are only-as-itself — any peer may answer for its own pane, and for no other. A call outside your role is refused, not queued.
4. Delivery is status-gated: one message per turn. Don't busy-poll a peer's terminal and don't re-send because a call looks slow — the bridge delivers when the peer is idle, blocked or done. A spawned member must also have mounted the bridge MCP: until it has, it is not deliverable, and a send waits on that gate for ~60s and then fails without ever reaching its pane.
5. Never move a fleet session, pane or peer except through the bridge. The bridge owns policy; the multiplexer owns PTYs. Any route that changes fleet state without the bridge's checks bypasses every rule above — the herdr CLI and its socket are the usual example.

Primary (lead) — run this on every task, in order

Delegate by default — that is the job. With the bridge mounted you are an orchestrator on a metered subscription, and workers are cheap, parallel, and disposable. The default answer to "who does this?" is a worker, not you. Reach for fleet_send before you reach for Edit. The steps below are the procedure — run them in order, every task, not only the big ones.

0. Know your role — fleet_whoami, once per session, before anything else.
1. Split. Write the unit list. Every unit carries: scope · the files or PR in question · acceptance criteria · exactly what to report back. A unit with no acceptance criteria is not ready to delegate — refine it or keep it.
2. Gate each unit on one question: "can I write a brief good enough for a worker to succeed?" — not "could I do this faster myself?" (usually you could; doing it yourself costs your context and your subscription, while a wasted worker turn costs a worker turn). Yes ⇒ delegate. The keep-list is closed: the conversation with the user, decomposition and planning, the final judgment call, verification, merges, and anything that depends on context only you hold. Nothing else is yours by default.
3. Spawn every delegated unit first — fleet_spawn{profile, worktree:true, ticket}, one per unit, before sending any. Pass profile explicitly: profiles differ in model, cost and LIVENESS, not in tier, so the default is rarely what you want. The default is whatever the daemon reports, and on a host where it sits on an exhausted or withdrawn credential every unqualified spawn fails — sometimes loudly, sometimes as a member that spawns fine and then produces nothing. fleet_profiles reports the default; check it once per session.
4. Then send them all — fleet_send{sessionId, content, wait:false}. Line 1 of every brief is Load the <name> skill. naming the worker's playbook; those skills are opt-in and that line is what makes them reliable. Where the project ships no such skill, spell the procedure out in the brief instead. The brief is self-contained — the worker sees your message and the repo, nothing of your context, your plan, or your screen.
5. Collect — fleet_poll{ticket} → fleet_ack{target, msgId}. Answer a worker's fleet_ask with fleet_send{turnId, content} — not sessionId. A worker gone quiet is diagnosed with fleet_status, never by reading its terminal; it also reports an open question and the turnId that answers it. A worker's ask waits ~55 seconds, and no nudge makes that longer — so never brief a worker to "ask me". Decide before you delegate, or give it an explicit default. A correction cannot reach a busy member. A fleet_send to a working member is accepted and returns a ticket, and is then never delivered — measured here three times in one session, and the member was released still executing a brief that had been retracted twice. The receipt is true and it is a fact about the mailbox; what you needed was a fact about the pane. A push delivery needs the recipient free at send time; a pull channel needs only that they look before acting. So put every correction on the ticket, which they can read whenever they look, and send as the notification. That obliges you, not them: all corrections go to the ticket, and the brief is write-once. The member cannot check which source is newer — it just always prefers the ticket — so the day you revise a brief in place instead of commenting, it obeys your rule and does the wrong thing. A first brief for a unit not yet running is not a correction, and may be the whole spec.
6. Verify yourself. Re-run the build and the checks. A worker cannot run your IDE tooling, any forge MCP server it appears to have holds a blocked credential and fails every call, and a piped command (… | tail) hides failures behind a zero exit — never promote a worker's "clean" to a fact. Its injected repo-scoped GITEA_TOKEN is a different credential and does work, so a worker reporting that it opened its own PR is reporting something it really can do.
7. Review — fan out. Spawn reviewers against the diff, one per dimension or per file, with wait:false. Never the implementer of the scope it reviews, and brief them from the diff — not from the implementer's rationale, which carries its own blind spot. Dispatch each PR's reviewers as it lands; don't wait for the last implementer. Under ~50 changed lines, skip the fan-out and read it yourself.
8. Adjudicate, merge, tear down — yours alone. Read the diff yourself: fully if it is small, targeted at the reported findings and the risky paths if it is large. Reviewer findings direct your attention; they never substitute for it. Then merge, then fleet_stop{paneId}. If the forge refuses you the merge — a protected branch, a token without the grant — the adjudication is still yours. Read the diff, decide, and hand the operator a merge-ready queue with the refusal quoted. Never report a PR as merged, and never call one "ready to merge" without having read the diff yourself. A refusal is exactly when that shortcut is tempting, because no action is left that forces you to look, and taking it turns this step into forwarding a reviewer's verdict — which is delegating the merge by proxy, two lines above. Test a refusal; do not read it off a permissions field. A protected branch holds its merge rights separately from the repository permissions, so that field can say yes while the merge is refused, and still say no after a grant makes it work. Probe instead, with a request that cannot succeed on its merits, so a rejection can only mean the refusal. Treat a transport failure as a third answer that proves nothing: a timeout, a DNS error or a bad URL is not a refusal, and counting it as one makes you sure of something you never measured.

Steps 3 and 4 are separate on purpose — spawning and sending in one loop is how parallel work silently becomes serial, and it is the most common way this layer is wasted. For the same reason, prefer wait:false + fleet_poll for anything non-trivial: a blocking fleet_send is capped by your own MCP client call timeout (~60s), well below the task's real runtime.

Delegating does not delegate responsibility. Workers open PRs; you are the gate. Never delegate the merge — and merging on a reviewer's word is delegating it by proxy.

When a decision blocks you, consult architects — not the operator. Spawn one or more architect members, give them the question and the evidence you have, and act on what they agree. They are authorized to settle it, not only to advise. If two of them still disagree after two rounds, they return both positions and you decide. Go to the operator only for something outside the fleet's authority: money, credentials, or a promise made to someone else. Then write the decision on the ticket. Taking the operator out of the loop also removes the signal they used to get, because that signal was the block itself — work stopped, so they found out. A ticket comment replaces it, and it reaches them whether or not they are at a terminal when you decide.

Intent	Tool
Confirm your own role	fleet_whoami
See backends available	fleet_profiles
Start a member	fleet_spawn{role?, profile?, cwd?, worktree?, ticket?, sessionName?, resumeSessionId?} → sessionId + paneId
See the fleet	fleet_list → leads (your peers) + members (each carries agentSessionId when its backend knows one) + loopHealth (RUNNING, STALLED, or STOPPED for statusPoller and sessionReaper) · one peer's state: fleet_status{sessionId}
Delegate (blocking)	fleet_send{sessionId, content}
Delegate (long task)	fleet_send{sessionId, content, wait:false} → ticket → fleet_poll{ticket}
Answer a member's fleet_ask	fleet_send{turnId, content} — not sessionId
Message a peer lead on this host	fleet_send{sessionId: <their terminal>, content} — fleet_list → leads reports it. Coordination only, never a task
Message a peer lead on another daemon or host	fleet_send{coordId: <their coord-id>, content} — needs a coordinator: block; your own coord-id is in fleet_list. Coordination only, never a task
Answer a peer lead that messaged you	fleet_send{coordId} — or {sessionId} if they are on this host. Not fleet_reply: it has no peer route and the publish is refused
Read your own held lead-to-lead mail (no ack)	fleet_poll{coordId: <your own coord-id, from fleet_list's coordinator.selfId>} — primary-only; never acks, so fleet_list's held[] still shows it after. fleet_list's held[] gives only a truncated preview — this is the only way to read the full body
Collect a held reply	fleet_poll{target} · then fleet_ack{target, msgId}
Tear down a member	fleet_stop{paneId}
Replace your OWN lead session when its context is full	fleet_handover{action:"open", reason?} → write the handover file it names → fleet_handover{action:"confirm", token, operatorConfirmed}. Primary-only. In that order: the file must be modified after open, or confirm refuses it as stale. There is no terminal parameter — the pane is always your own, so you can never roll another lead. {action:"cancel", token} drops a pending request

Lead ↔ lead — coordinate, never delegate

fleet_list returns leads alongside members; your own row carries self: true. Every other row is a peer — an orchestrator with its own context, its own members, and its own judgment. An empty members array means no members are spawned; it says nothing about peers.

A lead never assigns a task to another lead. Work goes to members — only ever downward, never sideways. Sending a peer a brief with acceptance criteria is a category error: a brief is a member's artefact, and a peer is not yours to task. If a unit needs doing and it falls in your area, spawn a member and delegate it yourself; if it falls in the peer's area, say so and let the peer assign it. The traffic between leads is coordination and nothing else:

1. Divide the map, not the work. Agree who owns which area, then each of you assigns inside your own. Split by context ownership — whoever already holds the context owns that area — and say who takes what, in one message, before either of you starts. Two leads silently working the same unit is the failure mode here, and neither notices until the merge.
2. Share findings, hazards, and corrections. What you have already discovered, what broke, what the next person will trip on. This is the traffic that actually pays for the channel: it costs one message and saves a peer a rediscovery.
3. Verify a peer exactly as you verify yourself. Peer status buys nothing: check the claim against the code, and re-run the build. A peer's correction gets the same treatment — right or wrong on the evidence, not on who said it. Neither of you merges the other's work unreviewed. N observations are N data points only if they differ in the axis you are trusting. This cuts both ways. N failures blamed on one cause are one data point when the cases share what you are not varying. N agreeing measurements are also one data point when they share an instrument — two hosts, two operators and the same formula is one formula, not two confirmations.
4. Ask a peer to read your project addendum. Your addendum is instruction surface: every future session on your host obeys it, and a wrong one is obeyed just as faithfully as a right one. The author is the worst reader of their own qualifier placement — measured here, one addendum carried two defects and a non-author found both. If you have no peer, at least re-read it asking "which sentence goes false first, and would a reader reach the caveat before acting?"

Being messaged by a peer does not make you its worker: answer the way you would open — fleet_send{coordId} for another daemon, fleet_send{sessionId} on this host — and push back on the substance if it is wrong. fleet_reply resolves a member's blocked fleet_send; a peer's coord-id message is durable and non-blocking, so there is nothing for it to resolve. A peer that simply complies has thrown away the reason there are two of you.

Member (worker or architect) — the turn contract

1. Load the playbook skill the lead named before doing anything else.
2. Do the assigned scope only. Note anything you spot outside it in one line; don't go hunt it.
3. fleet_ask{question} when a decision is genuinely the lead's (ambiguous requirement, two defensible fixes, "bug or intended?"). It blocks and you resume the same turn with the answer. Don't ask what you could decide yourself.
4. Re-read the ticket before you act on anything you were told earlier, and again before you commit. A message reaches you only while you are free to receive it; the ticket is there whenever you look. If a ticket comment contradicts your brief, the ticket comment is newer and it wins.
5. End the turn with exactly one fleet_reply{content}, carrying your complete answer. This is the whole handoff. No fleet_reply ⇒ the sender gets nothing and the exchange stalls. Do not lean on the completion fallback to carry your answer for you: when you end a turn without replying, the bridge scrapes your pane, and it can return only the last 4000 characters. A clipped scrape is marked as partial, but the missing text is gone — your report reaches the lead with its end cut off.
6. Report honestly. State only what you actually ran and its real output, including failures, and never claim the result of a check you had no way to run. Measure your own tools; do not assume them. What you mount depends on your backend: an opencode member gets the bridge and nothing else, while a Claude Code member also inherits the operator's user-scope MCP servers, which the bridge never chose for you. Two rules follow. The primary's IDE tooling is still not yours, whatever you see. And a mounted tool is not a working tool — the forge MCP server you may find there holds a deliberately blocked credential and fails every call, by design. That is not your only forge route, and the two must not be confused: the repo-scoped GITEA_TOKEN the daemon injects into your environment does work, and using it to open your own PR is part of the job. A blocked MCP tool is never a reason to skip that step.
7. Never merge. Stage files explicitly — never git add -A — and leave alone anything the project marks as not-yours-to-commit.

Where each rule lives (don't duplicate — extend the right layer)

Layer	Scope	Reaches
the launcher's reply charter	the one rule that must survive with no repo: end every turn with fleet_reply	every spawned member, at launch, every peer kind — never a lead
this section	protocol + orchestration policy	primary and every member that reads the repo — tracked in git, so worktrees inherit it
role agent definition files	role contract and per-job procedure	a member whose launcher binds its role to the matching file in its worktree
role playbook skills	per-job procedure (commit/PR recipe, finding format)	a member told to load one
the bridge's own docs	design detail, flows, error model	on demand

A rule belongs in exactly one layer — the outermost one that must obey it. A member without a repo checkout still gets the launcher's reply charter, which is why that one rule stays there. Peers that don't read CLAUDE.md (non-Claude adapters) get the charter only, so any rule they must obey belongs in the charter, not here.

Project addendum — claude-bridge (not part of the canonical block)

• This repo is the bridge. The daemon is fleetd, its MCP mount is http://127.0.0.1:8765/mcp, and the code behind the rules above is mcp/FleetMcp (tools), auth/Authz (the role table), mcp/ConnectionIdentity (connection→role), and worker/*Launcher (REPLY_CHARTER).
• Herdr socket tests (measured 2026-09-10). In this repo, herdr is a subject under test. A worker assigned to herdr code, and the lead, may let a test open the herdr socket directly in a throwaway workspace that the test tears down. This only covers fleetd/src/test/java/dev/ltms/fleet/herdr/AgentControlContractTest.java, fleetd/src/test/java/dev/ltms/fleet/herdr/HerdrContractTest.java, fleetd/src/test/java/dev/ltms/fleet/herdr/PaneLocatorContractTest.java, and fleetd/src/test/java/dev/ltms/fleet/herdr/WorkspacePlacementContractTest.java. It is not a general licence. Using the herdr CLI or socket to move a real fleet session, pane, or peer stays banned. That is the control plane that invariant 5 protects. Re-measure with grep -rl 'UnixSocketHerdrClient.connect()' fleetd/src/test/java --include='*.java'. A non-empty result means tests still open the socket and this note still applies. An empty result means nobody does this any more; delete this section. Canonical invariant 5 restatement is tracked in #458 and is not part of this change.
• fleet_profiles/fleet_list report two separate outage states, and they are not the same thing. Quarantined (CB-578) means the backend told us it is out of capacity — a long, 1800s-default cooldown. Cooling off (fleetd #201/#227) means a profile's credential threw two distinct backend errors (a non-exhaustion failure such as an HTTP 5xx) within 60 seconds — a short, fixed 60s cooldown, not configurable per profile. Each check runs independently, so a profile can show both at once. In the JSON: a cooling profile carries credentialId and coolingOffForSeconds; a quarantined profile carries quarantinedForSeconds; a profile hit by both carries all three fields, and either state alone already sets that profile's free to 0. A fleet_spawn naming a cooling-off profile is refused before it ever reaches the backend adapter, with a message naming the credential and the remaining seconds ("cooling off after repeated backend errors") — distinct wording from a quarantine refusal, so don't conflate the two when reading a spawn failure.
• Skills available to delegate: implementer (worktree → commit → push → own PR), reviewer (one diff → one structured finding) and hunter (sweep a package → several ranked findings, change nothing). Name exactly one in every delegation. reviewer and hunter are not interchangeable — reviewer caps the answer at one finding in about 90 words, so naming it for a multi-finding sweep hands the worker two contradictory output contracts. That has already cost three workers' turns: each wrote a good report to its terminal and ended the turn with no fleet_reply, and the scrape returned the tail of the brief instead. Spawn implementer with role dev, reviewer with role reviewer, and hunter with role hunter.
• Primary-side skills (not delegation playbooks — a worker cannot use them): port-to-opencode (make an OpenCode session a participant in this workspace), fleets-status (report every fleet that shares one LavinMQ instance), redeploy-fleetd (rebuild and restart the live daemon after a merge) and handover (write the file a fresh lead session inherits when the outgoing one hands off, fleetd #480).
• This repo is also a Claude Code marketplace, and ships a plugin. .claude-plugin/marketplace.json points at plugin/, which carries the MCP mount and the setup skill (/claude-bridge:setup — make any project bridge-ready). It was added in CB-527 and then went unmentioned by every instruction file, so it drifted and a later session planned it from scratch (#362). Read plugin/ before designing anything about onboarding a project. Two limits are structural, not bugs: a plugin cannot carry the role agent files, because ClaudeCodeLauncher.java:371 requires <cwd>/.claude/agents/<role>.md in the member's own worktree; and a plugin cannot deliver anything to members at all, because ClaudeCodeLauncher.java:285 exports CLAUDE_CONFIG_DIR and every Claude profile here sets it, so a member never reads the operator's plugin store. The plugin is the lead-side surface; member-facing assets travel in the worktree.
• Never commit .mcp.json (the primary's local copy, flagged --skip-worktree) or wiki/ (a submodule with its own remote).
• A provisioned worktree neutralizes .mcp.json, opencode.json and .autoenv — the repo's committed copies would otherwise mount the primary's IDE and forge servers (fleetd #134). The worktree's copy of each is a stub, not the repo's real file, so a worker that reads one and reports what it found is reporting on the stub. The daemon logs a per-spawn summary, but the worker cannot see that log. From inside its own worktree a worker — or a lead debugging one — reads the list with git config --worktree --get-all fleet.neutralizedConfig, and the consequence with git config --worktree --get fleet.neutralizedConfigNote. Never brief a worker to edit one of these files: the edit cannot be committed, and it will not tell you so.
• Flows and the error model — rendezvous, fleet_ask, detached delivery, the turn-done fallback and status gating — are diagrammed in docs/MCP-Contract.md. That page is now flows only: its pre-build tool catalogue, parameter tables and REST paths were deleted rather than corrected, because a hand-maintained second copy of the tool surface is what drifted for a month while this line pointed every session at it (CB-609 / #114). The live MCP schema is the tool reference, with the intent→tool table above as the short form. McpContractDocTest fails if that page names a fleet_* tool the server does not register. The flows are kept out of this file because this file loads into every session's context.

Redeploying the daemon — the lead may do this (primary only)

A merge is not a deployment. The running fleetd holds the jar it was started with, so a feature merged to main does nothing until the daemon is rebuilt and restarted. The lead may and should redeploy rather than hand the job back to the operator. Workers must never do this — a worker has no business restarting the daemon it is talking through, and stopping it kills the worker's own channel mid-turn.

Load the redeploy-fleetd skill before you redeploy. It holds scripts/redeploy-fleetd.sh and its flags, the drain step, the operator's permission grant, and the five checks that have each gone wrong here before. Do not hand-roll the steps from memory.

The prompt is part of the product — update it with the code (mandatory)

This repo is the bridge, so the canonical block above is not documentation about someone else's system: it is the instruction surface this codebase ships. Every change here must end by asking whether the block still tells the truth. A code change that silently invalidates it is an incomplete change — the agents reading it have no other source.

Before you call any work done, check the row that matches what you touched:

You changed…	Re-read and update…
a fleet_* tool — added, removed, renamed, or its params/semantics	the primary's intent→tool table; any rule that names that tool
Authz / the role table	invariant 3, and the primary-only vs worker-only claims
ConnectionIdentity / how a caller is resolved	the fleet_whoami paragraph and the fallback ladder
REPLY_CHARTER, or a launcher's mount/flags	the fallback ladder (mcp__fleet__*), and the layering table's top row
the injector / status gating	invariant 4
worktree provisioning or the parity overlay	the "both roles read this file" premise — it rests on the worker's worktree being a checkout of this repo
.claude/skills/**	the addendum's skill list, and the "name the playbook" rule
a new peer kind (non-Claude adapter)	what that peer can read — anything it must obey belongs in its charter, not in the block
anything an operator can use, configure, or observe — an MCP tool, a fleetd.yaml knob, an endpoint, a visible behaviour	Features — one entry: what it does · the knob that turns it on · why it exists · the gotcha

That last row is not bookkeeping. Chapters 1–10 answer how is this built and why this way; none of them has a home for what can it do and how do I turn it on, so for twenty tickets a shipped capability landed nowhere and the Roadmap went on claiming the stage was finished. The why line is the one that matters — without it a decision gets re-litigated from scratch a month later. Internal contract changes go to wiki/9-Implementation.md instead; test and coverage work is a Roadmap line. A change that touches none of the three earns no entry, and that is a normal outcome rather than an omission.

Then propagate: the block in this file and the template in the wiki (Use Cases → The portable CLAUDE.md block) must stay byte-identical, and other projects carrying the block need the same edit. Verify rather than trust:

python3 - <<'PY'
import pathlib
c = pathlib.Path("CLAUDE.md").read_text()
w = pathlib.Path("wiki/7-Use-Cases.md").read_text()
S, E = "## Bridge communication (enforced", "## Project addendum — claude-bridge"
block = c[c.index(S):c.index(E)].rstrip() + "\n"
i = w.index("```markdown\n") + len("```markdown\n")
print("in sync:", w[i:w.index("\n```\n", i) + 1] == block)
PY

Only the lead can run that check (measured 2026-09-10). A member's provisioned worktree has wiki/ uninitialized, so the script dies with FileNotFoundError: wiki/7-Use-Cases.md. Measured in three worker worktrees: git submodule status printed a leading - and wiki/ held 0 entries; the primary's own clone printed a leading + and the file was there. So never make this check a member's acceptance criterion — it is unsatisfiable for them, and a brief that asks for it is asking a worker to invent a pass. A member told to check it must say it could not run it, and must never report it as passed. The lead runs it in the main clone before merging. Re-measure with git submodule status in a member's worktree: a leading - means this still applies; once it prints a commit with no -, delete this paragraph.

IDE MCP tools & validation workflow (enforced)

Primary only. Workers have no IDE MCP mount — if you are a worker, skip this section and report the build/test output you actually ran (see §Bridge communication → Worker).

Two IDE MCP servers are connected: intellij-index (semantic code intelligence) and jetbrains (file problems, reformat, debugger). IntelliJ has multiple projects open; our module is fleetd. Always pass these to IDE MCP tools:

• project_path = /Users/dai.ha/LTMS/claude-bridge/fleetd
• IDE paths are relative to fleetd/ (e.g. src/main/java/dev/ltms/fleet/...)

After editing any file — mandatory

1. ide_sync_files{paths} — the built-in Edit/Write tools write to disk; the IDE index is stale until synced, or IDE nav/refactor/diagnostics give wrong results.
2. ide_diagnostics{file} (or jetbrains get_file_problems) — clear all errors and warnings. IDE inspections catch what a build won't (unused params/fields, redundant modifiers, resource leaks, "always same arg", …). These diagnostics are per-file.
3. mvn clean install (Bash) — required for overall project health (clean build + full test run). A per-file-clean file can still break the build or another module. This is the whole-project gate before declaring work done or committing.

Whenever dependencies change (or a pom.xml edit), validate CVEs with jetbrains get_file_problems{filePath: "fleetd/pom.xml"} — its Mend.io check reflects the dependencies on disk. (Note: ide_diagnostics / intellij-index does NOT re-resolve dependencies after a pom edit without a full Maven reimport, so it reports stale CVE results — don't trust it for this.) Treat a CVE warning like any other: bump to a patched version and confirm mvn clean install still passes. If the latest available version is still flagged (EOL line, "insufficient information", or config-file-only advisories), document it as accepted in the pom rather than chasing a fix that doesn't exist.

Use IDE MCP tools for navigation, refactoring, and diagnostics only

• Navigate (prefer over Grep/Read for symbols): ide_find_definition, ide_find_class, ide_find_file, ide_find_references, ide_find_implementations, ide_find_super_methods, ide_call_hierarchy, ide_type_hierarchy, ide_search_text (regex: jetbrains search_in_files_by_regex).
• Refactor (prefer over multi-file Edit / rm / mv): ide_refactor_rename (position-based, updates all refs/overrides/tests), ide_refactor_safe_delete, ide_move_file, jetbrains reformat_file.
• Diagnose: ide_diagnostics / jetbrains get_file_problems.

Do NOT route build/test/one-offs through the IDE

Keep mvn (compile/test/package/clean install) and all one-off shell commands on Bash. Do not use jetbrains build_project, execute_run_configuration, or execute_terminal_command to replace them.

Java 25 notes

Prefer the unnamed lambda parameter _ for required-but-unused params; a non-public static void main(String[]) is valid (JEP 512) and boots via java -jar.
