/mine-corrections

You are running the LLM stages of chat-arch's correction-mining pipeline. The exporter has already produced a heuristic-recall list of candidate corrections. Your job: classify them, cluster repeated rules, check whether each rule already exists in the user's config, and propose concrete upgrades.

When to invoke

• The user runs /mine-corrections (optionally with arguments below).
• The viewer wrote a request to chat-arch-data/analysis/correction-requests.json (you'll see a --request-id arg in that case).

Arguments

Parse from the user's message. Defaults in brackets.

• --data-dir <path> [defaults to ./chat-arch-data relative to repo root, or whatever the user names]
• --window-days <N> [30] — only process corrections from sessions updated within the last N days. Most-recent-first ordering. Ignored when --candidate-ids-file is also passed.
• --candidate-ids-file <path> [omitted] — JSON file with { "ids": ["cor_...", ...] }. When present, processes ONLY those correction ids regardless of --window-days. The API endpoint writes this file when auto-window selects candidates by composite (signal × recency) score rather than a pure time slice. Honor this list verbatim.
• --request-id <uuid> [omitted] — present when invoked from the viewer; correlates status/output with the requesting UI.
• --max-sub-agents <N> [40] — abort if the work plan would dispatch more than N sub-agents. Each batch of 20 candidates = 1 classification sub-agent; each cluster = 1 proposal sub-agent. The bound prevents a runaway window from quietly burning a chunk of your Claude Code plan usage.
• --no-llm [false] — skip stages 2, 4 (proposal LLM); useful for dry runs and CI.
• --reclassify [false] — re-process already-classified corrections (default skips them).

Pipeline

You orchestrate six stages. Update the status file at every transition.

Stage 0 — Setup

1. Resolve --data-dir. Read ${dataDir}/analysis/correction-candidates.json. If absent, tell the user to run pnpm --filter @chat-arch/exporter run start ... first.
2. If --candidate-ids-file is set: read it, take the ids array, filter correction-candidates.json to ONLY those ids. Skip the time-window filter entirely. This is the auto-window's preferred path — composite (signal × recency) ranking already happened upstream. Else (legacy / explicit --window-days): filter to candidates from sessions whose updatedAt is within --window-days of now. Use the manifest at ${dataDir}/manifest.json to look up session timestamps by sessionId. Sort most-recent-first.
3. Verify Ollama is up. Run Bash:

   curl -s -m 1 http://localhost:11434/api/tags > /dev/null && echo OK || echo MISSING
   

   If MISSING, tell the user: "Ollama is not running. Install from https://ollama.com, then ollama pull mxbai-embed-large." Stop.
4. Estimate sub-agent count: ceil(numCandidates / 20) + estimatedClusters (estimate clusters as ~numCandidates/8 for a first pass; tighten on subsequent runs once you know the real cluster ratio). Log the estimate to status either way. All sub-agent calls run inside the parent Claude Code session — no separate billing, but each call counts against the user's plan usage.
   • When --candidate-ids-file is set (the viewer wrote it): skip the interactive cap-and-ask entirely. The viewer's /api/mine-corrections endpoint only writes that file after the user confirmed the count + window in the ArmedPreview dialog, so re-asking here is a) redundant and b) silently fatal in headless claude -p mode where there is no one to answer. Proceed regardless of --max-sub-agents and log "viewer-confirmed run (NN candidates) — skipping sub-agent cap check".
   • Else (direct CLI invocation, no id file): if the estimate exceeds --max-sub-agents, ask the user before proceeding. This path has a human at the terminal who can answer.
5. Write the initial status file.

Stage 1 — Classification

Goal: turn each candidate into a structured CorrectionClassification (kind, distilledRule, confidence, actionable). Drop the rest.

Batch candidates into groups of 20. For each batch, dispatch a general-purpose sub-agent with model: "haiku". Classification is a structured-output task — Haiku 4.5 handles it well at a fraction of the rate-limit cost of Opus, and proposal generation later (Stage 5) keeps the default Opus where judgment matters. Run multiple batches in parallel — up to 4 at a time — by sending multiple Agent tool calls in a single message.

Use this exact sub-agent prompt template (substitute the candidate JSON in place of <<CANDIDATES>>):

You are classifying user-corrections-to-AI from a chat transcript. Each input is a {sessionId, userTurnIndex, excerpt, precedingAssistantExcerpt, signals} object.

For each input, decide:
1. Is this an actual correction-to-the-AI (an instruction, behavior rule, format demand) — actionable?
2. If actionable, what KIND: 'behavior-rule' | 'output-format' | 'tool-preference' | 'factual-fix' | 'tone' | 'process' | 'other'.
3. Distill the rule into ONE imperative sentence. No first-person, no project-specific identifiers, no quotes from the assistant. Example: "don't add docstrings unless the user asks." Bad example: "the user wants me to stop adding docstrings."
4. Confidence (0..1): how confident are you this is a real, repeatable correction (not a one-off fix or aside).

Output ONLY a JSON array, one entry per input, same order:
[{"id": "<correction id>", "actionable": true|false, "kind": "...", "distilledRule": "...", "confidence": 0.0-1.0}]

Inputs:
<<CANDIDATES>>

Each sub-agent returns its JSON. Concatenate results. If any sub-agent fails or returns malformed JSON, retry once; if still bad, drop those candidates with a status message.

After all batches: filter to actionable: true AND confidence >= 0.6. Update status: "classified N of M, K kept after filter".

Write the intermediate file ${dataDir}/analysis/_corrections-classified.json (the leading underscore signals "intermediate, not consumed by viewer"):

{
  "generatedAt": <now>,
  "corrections": [<each Correction with classification populated>],
  "patterns": [],
  "pipeline": { "heuristicRecall": true, "llmClassification": true, "embeddingClustering": false, "claudeMdCrossCheck": false }
}

Stage 2 — Config ingestion

Discover the user's existing CLAUDE.md / skills / agents / commands / settings.

# Build the project-roots list from the manifest's distinct cwd values.
node -e "
const m = JSON.parse(require('fs').readFileSync('${dataDir}/manifest.json','utf8'));
const roots = [...new Set(m.sessions.map(s => s.cwd).filter(Boolean).filter(c => !c.startsWith('/sessions/')))];
require('fs').writeFileSync('${dataDir}/analysis/_project-roots.json', JSON.stringify(roots));
"

# Run the ingestion CLI. The home-dir default is fine.
node packages/exporter/dist/cli/ingest-configs-cli.js \
  --project-roots-file ${dataDir}/analysis/_project-roots.json \
  --output ${dataDir}/analysis/_configs.json

Stage 3 — Embed everything

Embed (a) the distilled rules, (b) every config sentence. Two batched calls to chat-arch-embed.

# Rules
node -e "
const c = JSON.parse(require('fs').readFileSync('${dataDir}/analysis/_corrections-classified.json','utf8'));
const texts = c.corrections.filter(x => x.classification?.actionable).map(x => x.classification.distilledRule);
require('fs').writeFileSync('${dataDir}/analysis/_rules-input.json', JSON.stringify({ texts }));
"
node packages/exporter/dist/cli/embed-cli.js \
  --input ${dataDir}/analysis/_rules-input.json \
  --output ${dataDir}/analysis/_rules-vectors.json

# Sentences
node -e "
const cf = JSON.parse(require('fs').readFileSync('${dataDir}/analysis/_configs.json','utf8'));
const texts = cf.documents.flatMap(d => d.sentences.map(s => s.text));
require('fs').writeFileSync('${dataDir}/analysis/_sentences-input.json', JSON.stringify({ texts }));
"
node packages/exporter/dist/cli/embed-cli.js \
  --input ${dataDir}/analysis/_sentences-input.json \
  --output ${dataDir}/analysis/_sentences-vectors.json

If an embed call fails, surface stderr to the user. Likely cause: Ollama dropped, or the model isn't pulled (ollama pull mxbai-embed-large).

Stage 4 — Cluster + already-encoded check

node packages/exporter/dist/cli/cluster-corrections-cli.js \
  --classifications ${dataDir}/analysis/_corrections-classified.json \
  --configs ${dataDir}/analysis/_configs.json \
  --output ${dataDir}/analysis/_patterns-no-proposals.json

This reads the classifications + configs and writes patterns with proposedUpgrades: []. Each pattern has its alreadyEncoded and confidence fields populated.

Update status: "clustered into K patterns (J already-encoded)".

Stage 5 — Proposal generation

For each pattern, dispatch a sub-agent to generate ProposedUpgrade[]. Process patterns in parallel up to 4 at a time. Use the default model (Opus) — proposal generation requires judgment about which target file to recommend, why the existing rule is failing, and what the patch text should say. Don't downgrade to Haiku here.

For each pattern, build the sub-agent prompt with:

• The pattern's canonicalRule, occurrenceCount, alreadyEncoded.
• 3-5 representative instances (excerpt + precedingAssistantExcerpt) — pick the highest-confidence ones.
• The relevant config documents (those whose sentences had highest similarity to the rule). Truncate each to ≤2000 chars.
• The list of distinct project roots affected (lookup via session→cwd from the manifest).

Sub-agent prompt template:

You are proposing a concrete fix for a recurring AI-correction pattern.

PATTERN
canonicalRule: <text>
occurrenceCount: <N>
alreadyEncoded: <true|false>
projectsAffected: [<roots>]

INSTANCES (5 most representative):
<excerpt + preceding assistant text for each>

EXISTING USER CONFIG (most relevant, may be empty):
<excerpts of any CLAUDE.md / SKILL.md / agent / command / settings document with high similarity>

PRODUCE: a JSON array of ProposedUpgrade objects, ranked best-first. Each object:
{
  "target": "global-claude-md" | "project-claude-md" | "settings-hook" | "skill" | "prompt-snippet" | "agent" | "command",
  "targetPath": "<concrete file path or settings.json key>",
  "headline": "<one plain-English sentence — what the upgrade does and why it matters>",
  "patch": "<the literal text to add or the unified diff if replacing>",
  "rationale": "<one paragraph; cite at least 2 instance ids by '<corId>' format from above>",
  "applied": false,
  "appliedAt": null
}

CONSTRAINTS — non-negotiable:
- patch must be CONCRETE TEXT, not a description of what to add.
- headline must be ≤15 words, plain English, and name BOTH the rule being changed AND the change itself. Good: "Widen 'adversarial review' rule to fire on plans/lists/decisions, not just experiment results." Bad: "Update CLAUDE.md." / "Improve the adversarial review rule." / "Add a hook for tests." (Last one would be fine if rewritten to name the rule: "Add PostToolUse hook so 'run tests before committing' enforces itself.")
- If alreadyEncoded is true: the existing rule is failing. Your top-ranked proposal MUST be a reword (with the failure diagnosed: why is the model violating the existing rule?) OR an escalation to deterministic enforcement (hook). Do NOT propose adding a new rule when one already exists.
- If projectsAffected is one project: prefer project-claude-md over global-claude-md.
- If projectsAffected is many projects: prefer global-claude-md.
- If pattern is process-y and tool-bound (e.g. "always run X before Y"): consider a hook over a CLAUDE.md rule.
- If pattern is workflow-shaped (e.g. "when reviewing code, do X"): consider a skill or agent.
- rationale must cite at least 2 instance ids.
- No flattery. No "you have great instincts." Pure mechanism.
- If you cannot produce ≥1 valid proposal under these constraints, return an empty array. Do not produce a low-quality proposal to fill the slot.

Output ONLY the JSON array.

After all sub-agents return, validate each proposal:

• patch non-empty
• targetPath non-empty
• rationale cites at least 2 strings of the form <corId> that exist in the cluster's instanceIds
• target is one of the allowed values
• headline non-empty and ≤15 words (split on whitespace). If absent or too long, do NOT drop the proposal — instead, set headline to the first sentence of rationale truncated to 15 words. Headline is a UX-quality field, not a correctness gate; a long headline beats no headline beats dropping the proposal.

Drop invalid proposals. If a pattern ends up with zero valid proposals, keep the pattern but with proposedUpgrades: [] and note it in status.

Stage 6 — Tag topics

Goal: assign every pattern (this run's new patterns AND any prior patterns preserved across runs) a short topic label that drives dynamic bucketing in the viewer. ONE LLM call sees all patterns at once — clustering needs a global view to keep labels coherent (no fragmentation between "Git Workflow" and "Git Practices").

1. Read existing ${dataDir}/analysis/corrections.json if present. Collect prior patterns. Combine with this run's freshly-clustered patterns from _patterns-no-proposals.json (or with proposals from the staging step above — only canonicalRule is needed here).
2. If the combined pattern count is ≤ 1, skip this stage (one pattern doesn't need clustering — leave topic undefined).
3. Build the topic-tagging prompt with the full pattern list. Use the default model (Opus) — taxonomy quality is the whole point and Haiku tends to over-cluster.

Sub-agent prompt template (single sub-agent, NOT parallelized — taxonomy needs a global view):

You are clustering correction patterns into a small number of topic categories. The user will browse patterns grouped by topic, so the labels must be:
- short (1-3 words, Title Case)
- mutually distinct (don't return two labels that mean the same thing)
- balanced (aim for 4-8 topics across the corpus; merge sparingly-populated themes into a broader parent)
- stable in shape across runs (same corpus → same labels)

INPUTS — every pattern in the corpus:
[{"id":"p_...","canonicalRule":"...","occurrenceCount":N,"alreadyEncoded":bool}, ...]

PRODUCE — a JSON object mapping each pattern id to a topic label, plus the deduplicated topic list:
{
  "topics": ["Git Workflow", "Test Discipline", ...],
  "assignments": { "p_abc123": "Git Workflow", "p_def456": "Test Discipline", ... }
}

CONSTRAINTS — non-negotiable:
- Every input id appears in `assignments`. No id is dropped.
- Every value in `assignments` appears in `topics`. No orphan labels.
- Topic labels are 1-3 words, Title Case, no punctuation.
- Don't invent a "Misc" or "Other" bucket. If a pattern truly doesn't fit, group it with the nearest semantic neighbor.
- Don't pad to a fixed count. If the corpus genuinely splits into 3 topics, return 3.

Output ONLY the JSON object.

Validate the response:

• Parse as JSON; on failure, retry once. On second failure, log a warning and skip the stage (patterns ship without topic — viewer falls back to an Untagged bucket).
• Every pattern id present? Every assigned label in topics?
• If validation fails, drop the stage rather than ship inconsistent data.

Apply the assignments: for each pattern in this run's set AND any prior pattern that was passed to the LLM, write topic = assignments[patternId]. Patterns NOT in the input list (none, if you built the input correctly) keep their existing topic field as-is.

Update status: "tagged N patterns into K topics: [<topics>]".

Stage 7 — Assemble + write

Merge classifications + patterns + proposals into the final CorrectionsFile. Critical: preserve any prior corrections in corrections.json that this run did NOT touch — they keep their existing classification (or null if they were never classified). Only overwrite entries for candidates this run classified.

{
  "generatedAt": <now>,
  "corrections": [<merged: prior entries + this run's freshly classified, classification populated where known, null otherwise>],
  "patterns": [<merged: prior patterns retained, this run's new patterns added>],
  "pipeline": { "heuristicRecall": true, "llmClassification": true, "embeddingClustering": true, "claudeMdCrossCheck": true }
}

The merge step is what makes the auto-window's "incremental" promise hold. If you wholesale-replace corrections.json with only this run's processed candidates, the next auto-window run will treat anything you didn't touch as unprocessed and try to re-do it.

Write to ${dataDir}/analysis/corrections.json. Then DELETE the intermediate _*.json files (clean up), including the _correction-target-ids-${requestId}.json file the API endpoint wrote when --candidate-ids-file was used.

Update status to complete with summary counts.

If a --request-id was passed, also write a completion marker at ${dataDir}/analysis/correction-status-${requestId}.json:

{ "requestId": "<id>", "status": "complete", "completedAt": <now>, "patternCount": N, "alreadyEncodedCount": K, "tokenCost": "<estimate>" }

Loop closure (subsequent runs)

When invoked with --reclassify OR when corrections.json already exists with applied proposals:

1. Load existing corrections.json. Note which patterns have proposedUpgrades[*].applied === true with appliedAt set.
2. For each "applied" pattern, check whether new corrections (post-appliedAt) match the same canonical rule (use embedding similarity ≥ 0.85 against the canonicalRule).
3. If yes: set recurringPostApplication: true on that pattern. The viewer surfaces it as "applied but still recurring" — top priority.
4. Also re-read the file at appliedAt's targetPath. If the rule's normalized canonical no longer appears there (user edited it away), retire the proposal — set applied: false and clear appliedAt. The pattern goes back into the queue normally.

Status file format

${dataDir}/analysis/correction-status-${requestId}.json:

{
  "requestId": "<id or 'manual'>",
  "status": "starting" | "classifying" | "ingesting-configs" | "embedding" | "clustering" | "proposing" | "tagging-topics" | "writing" | "complete" | "error",
  "progress": { "phase": "<current>", "current": N, "total": M },
  "startedAt": <ms>,
  "updatedAt": <ms>,
  "log": ["<recent message>", "..."],
  "error": "<message if status=error>"
}

Update on every stage transition. The viewer polls this for live progress.

Error handling

• Ollama down → stop, tell the user how to start.
• Manifest missing → stop, tell the user to run the exporter first.
• Sub-agent malformed JSON → retry once, then drop those candidates and continue.
• Sub-agent count over --max-sub-agents → ask, don't proceed silently. Exception: when --candidate-ids-file is set (viewer-confirmed run), the user already confirmed in the ArmedPreview dialog; proceed regardless of the cap. Asking would silently abort the run.
• Any unrecoverable error → write status: error with message, exit.

What you must NOT do

• Don't auto-apply proposals. Writing to ~/.claude/CLAUDE.md or settings.json without explicit per-proposal user approval is out of scope. Propose only.
• Don't post-process or re-rank proposals from sub-agents. They produce ranked lists; preserve order.
• Don't invent instance ids in citations. The validator drops proposals citing nonexistent ids.
• Don't write to corrections.json until stage 6. Use _ prefix for all intermediate files.
• Don't re-classify already-classified corrections unless --reclassify was passed.
• Don't proceed if cost estimate exceeds the cap; ask first.
