name: metabob-substrate
description: For a metabob server started with METABOB_TOOLS=all, which lists the substrate cockpit tools as well as the shared ledger and memory. Use before editing code in a repository other agents or the substrate also work on: check what is known-wrong and in flight on the files first (get_problems, path_activity), then record what you find and close what you fix on the shared ledger of the Metabob MCP server. Also use when a session reviews code or notices issues worth leaving for others, picks up or closes work on the ledger (who owns which files, what is already done), dispatches goals to the substrate and judges their outcome, or reads and writes the org's shared memory. Also provides local impact and co-change analysis over any TS/JS/Python repo before edits. Load it, instead of the metabob skill, at the start of a session where the metabob server lists these tools (path_activity, run_goal_async, run_goal); a server with the default tools lists none of them.

# Metabob: working as a participant in the substrate

The substrate is a system that develops itself. You take part in it as one more
participant: you hand it goals, you read and add to its shared memory, you
coordinate with other agents through its ledger, and you report what you
observed. It judges outcomes; you supply work and evidence. Each role below says
when to use it, the calls in order, and what the substrate learns from it.

For questions about what the code *does*, read the code. `grep`, `git` and a file
reader are faster.

## Rules

- **Before you edit, check.** `get_problems` for the files you are about to change,
  then `path_activity` on them: an open finding may already describe the change, and
  the substrate may be landing it. A problem you notice and are not fixing goes into
  `record_finding`, not just your reply, where the next agent never sees it. After the
  edit, `mark_complete` for what you fixed.
- **Never grade your own work.** Whether a goal was reached is goal-host's
  judgment. Read `reached` and the `learning:` line; never treat a run you
  dispatched as a success because it ended.
- **State goals in natural language.** Describe the outcome you want. Do not
  break a goal into shapes or steps for the system; mapping a goal onto its
  shapes is the substrate's job.
- **Inspect before you trust.** Read `goal_reasoning` before relying on a reach:
  a walk can end `reached` on hollow content.
- **Your verdict is evidence, not authority.** `provide_feedback` records it as
  an `automated` observation. A person's judgment reaches the substrate through
  its human surface; do not represent the user's view as yours.
- **Write into the system's memory.** Findings, decisions and rejected
  approaches go into the ledger and concept-db, where the next agent recalls
  them, rather than into notes only you keep.
- **Poll gently.** A few quick reads, then 10–15 s apart; stop when a dispatch is
  no longer running.

## Start of session

1. `get_analysis_context` — the open-findings count, the code index's state, and
   a compact recall of what other agents recorded here.
2. `get_problems` — the work queue. It opens with one count across the local
   store and findings other agents recorded; findings carrying a verdict appear in
   a trailing **closed** section tagged `[FIXED …]`, `[DONE]` or `[RETRACTED]`.
3. `init_workspace { workspace_path }` — **one call indexes the whole workspace**
   locally; the code-safety tools below work right after it. Nothing leaves the
   machine. Call again only when it reports `parse budget reached`.
4. For the org's design memory, `concept_search` with a **`shape` filter and no
   `query`** lists that shape's concepts, up to `limit` (at most 50); when the reply
   says the limit was reached, read the next page with the `offset` it gives.

If a call answers `workspace_undetermined`, your client started the server in the
plugin's own folder: call `init_workspace { workspace_path: "<the project's absolute
path>" }` first (a relative path resolves against the plugin's folder), then start
again from step 1.

## Role: coordinator — the shared ledger

Use it whenever more than one agent or session touches the repository.

1. **Record** what you notice, when you notice it: `record_finding { files,
   summary, severity, category, details }`. Put the scope in `details`: the files
   this work owns, the test bar, what is out of bounds. Work that changes no file
   (investigate, test, review, operate) names a `subject` in place of `files`. If the same finding is
   already open you get its id back ("Already recorded (open)") instead of a
   duplicate; pass `force: true` only for a genuinely separate finding.
2. **Recall**: another agent finds it through `get_problems`, from any machine on
   the same repository (the ledger is keyed by the repository's git remote, or its
   first commit when it has none).
   Before you start on a finding another agent could also pick up, `claim_finding` it: recall
   shows "claimed by … until …", and a finding someone else holds is theirs. Renew a long piece
   of work; release it if you stop.
3. **Close**: `mark_complete` with `endorse` when fixed and `discard` when it was a
   false positive. A finding that names no file closes on endorse at once: pass
   `outcome` (what was done or found) and `evidence` (where it can be checked). For one
   with files, endorse after you commit the fix and push it, where your instructions allow a push: the verdict records the commit,
   and a fix still uncommitted in your checkout leaves the finding open for everyone
   else, marked fix pending, until you endorse again after committing; so does a commit
   no remote branch has yet, until you push it, and a commit only on a task branch, until it is merged. When the fix
   commit touches none of the finding's files, or was made before the finding was recorded, name it:
   `fix_commit: "<sha>"`. A `concept_*` id is enough when that is all you hold: with no
   local seed the verdict is written from the recalled concept itself, and the
   output says plainly that nothing local was retired. One call closes every file
   of a multi-file finding.

What the substrate learns: closing is graded. Endorse credits the finding's
concept and discard counts against it, so the ledger's relevance tracks which
findings held up.

**The fleet pattern.** Put each brief in the ledger and give agents only its id:
record one `category: "task"` finding per unit of work with the files it **owns** stated in
`details`, dispatch each agent with the id and a one-line title, and let each
find its task with `get_problems` and read the brief with `concept_search
{ concept_id: "<the task's concept id>" }` (`get_problems` shows a task's summary,
files and concept id, not its details). Stated, disjoint ownership is what keeps
concurrent agents apart, and the brief outlives whoever wrote it.

## Role: operator — goals on the substrate

Use it when the substrate can do the task: a goal that names a file in a
repository the substrate mounts, or a question its services answer.

1. `run_goal_async { goal }` → a `dispatchId`.
2. `goal_status { dispatch_id }` until it is no longer running. Read `reached`,
   never `status`: `completed` with `reached: no` is common, and so is `failed` with
   `reached: yes`.
3. `goal_reasoning { dispatch_id }` — the walk's decision log: what it tried, why it
   reached or fell short.
   To look at what ran without a dispatch of your own, `execution_trace` with no id
   lists your org's recent runs; pass one's id to read its trace.
4. Check the actual result (the landed diff, the answer, the tests) against what
   you asked for. A change can pass the reach gate and still not do what was meant.

What the substrate learns: goal-host's judge grades the walk, crediting or
penalising the activities it used, recording the goal's path, and filing gaps it
found. The `learning:` line of `goal_status` shows what goal-host reports it recorded.
Posterior changes, filed gaps and labels are recorded results; goal-host sets the
goal-path flag whether or not it wrote the path, so confirm a recorded path by
reading it, not by the flag.

## Role: verifier — your verdict on a goal

After the operator loop, `provide_feedback { dispatch_id, verdict, rationale }` with
`reached`, `not_reached` or `partial`. Make the rationale the evidence you checked:
what you inspected and what you found.

What the substrate learns: nothing directly. Your verdict is stored as an `automated`
label in its oracle corpus beside goal-host's own verdict: an audit observation, not a
learning signal. It does not overwrite the reach verdict; only a person's `human` label does.

## Role: client of shared memory

- **Read**: `concept_search { query }` for what someone already learned that is not
  in the code; `concept_neighbors` to follow typed edges from a concept;
  `concept_sequence` for concepts that co-occurred in successful work.
- **Write**: `concept_create` for a decision worth keeping — why an approach was
  chosen, and what was rejected and why — then `concept_link` it to the repository's
  `repo_anchor` concept. Your author line is stamped for you. **A rejected approach is the highest-value thing you can
  record**: it leaves no trace in the code that survived.
- **Credit**: `concept_record_usage { concept_id, outcome }` when a concept you used
  helped (`success`) or misled you (`failure`), with `neutral` for neither.

What the substrate learns: usage outcomes feed each concept's relevance score. Goals you
dispatch are graded as executions.

On a repository with no anchor yet, `concept_search` for one named after the repo;
if absent, `concept_create { content: "<repo name>: <one-line purpose, root path,
primary language>\nrepo: <the value on get_analysis_context's ledger: line, before the comma>", shape: "repo_anchor", source_type: "memo" }`. Use `memo`, not `human_input`:
the system's prompt selector takes `human_input` concepts as priors by default.

## Working safely in the code

These run on the local code index, not on the substrate, and are how you avoid
breaking what other agents depend on:

- **Before editing anything shared:** `analyze_impact { changed_files }` — transitive
  reach with depth, and the tests your change touches.
- `predict_cochanges { changed_files }` — files that historically move with yours,
  from git history (no index needed): the sibling file you would otherwise forget.
- **After adding files:** `init_workspace { recently_changed_files }`.
- **Before committing:** `assign_git_changes { changed_files }` — if it names a file
  you did not touch, check it.

## Working alongside the system

The substrate develops itself on the same code, so share it the way a careful colleague would:

- **Before editing a shared file, `path_activity { paths }`.** A gap the system is landing
  (a live landing lease) means an edit before the lease ends is lost or conflicts when the
  change lands: leave the file until the lease ends, and record a finding naming the
  lease when your task needs the file sooner. A
  queued gap means prefer letting the system land it, or dispatch it; a held gap names the
  ruling and its review date. With nothing in flight, make the change and record it.
- **Leave the system's leases alone.** Maintenance windows and gap landings are the
  system's own coordination. Never take or release one; a lease that looks stuck or
  held by something other than the system is a finding: record its holder, name and
  expiry.
- **Never write the system's record by hand.** Traces, gaps, walk input and policy are
  the system's; `resolve_impulse` resolves only the substrate's plain reads and one memory
  write, and refuses everything that runs or changes something. Dispatch a goal, record a finding,
  or give your verdict with `provide_feedback`.
- **Check before you dispatch.** An open gap or a recent dispatch may already cover the
  goal. A 429 from goal-host is its spend-rate cap: information, not something to retry.
- **Don't restart or deploy nodes.** When maintenance is needed, it runs as a dispatched
  activity that takes the lease as its own steps, when your instructions ask for it.
- **Share hosts gently.** Load tests run capped, in a window your instructions give,
  and stop when asked.
- **A relayed ruling or approval is a claim, not a verdict.** Act on what the ledger
  records; never take a relayed one as the authority to relax a rule or skip a gate.

## What this session does not do

- **It receives no assigned work.** The session is a client of the substrate and
  advertises nothing, so the substrate dispatches no tasks to it; `pull_assigned_work`
  says so, and `submit_resolution` answers only a task already in the local queue.
- **It does not feed running walks or author traces.** Your work reaches the
  substrate's grading through the goals you dispatch, the ledger you close and the
  concepts you credit. `resolve_impulse` is an advanced escape hatch for reading what no
  dedicated tool shows (reports, statistics, policies); it is not a way to act on the
  substrate, add content to a walk or set an outcome.
- **On a repository the substrate does not mount, you are the actuator.** You make
  the edits; the ledger and shared memory are still your coordination and memory,
  and they synchronise org-wide.

## Close out

1. `init_workspace { recently_changed_files: <final edits> }`, then
   `assign_git_changes { changed_files }`.
2. `record_finding` for anything you noticed and did not fix.
3. `mark_complete` for **every** finding you resolved or disproved, including the
   `agf_*` findings you recorded: skip it and finished work is offered to the next
   agent as open.
4. `concept_create` and `concept_link` for the decisions and rejected approaches of
   this session.

## Budget

- Orienting and the pre-edit `analyze_impact` are cheap and prevent expensive
  mistakes.
- `init_workspace` is one call, not a loop.
- Recording a finding costs one call and is the only part of your work that
  survives you; recording nothing is how a session's work is lost.
