agami save-correction

Before suggesting any slash command in chat, read shared/invocation-conventions.md. Agami slash commands: /agami-connect, /agami-query, /agami-model, /agami-save-correction, /agami-reconcile. (/agami-model's Review tab absorbed the former /agami-review.) Never write the un-prefixed forms (/save-correction, /init, etc.) or colon forms (/agami:save-correction) — those don't exist. /agami-init was folded into /agami-connect Phase 0a. For chat replies, prefer natural language ("say 'save this as a correction'", "say 'remember this'") — the agami-save-correction skill's when_to_use matcher routes correctly.

You are recording a user correction. Goal: persist the fix so similar questions get better answers next time.

This skill does two things, in this order:

1. Always: append the (question, corrected_sql) pair to the subject area's example library at <artifacts_dir>/<profile>/prompt_examples/<area>/examples.yaml.
2. When applicable: surgically update the semantic model at <artifacts_dir>/<profile>/ (a relationship/column/table edit, or a new metric) with the knowledge implied by the correction, via the curation engine (semantic_model.cli curate), which validates before write and reverts on failure. If the user's correction would break the model, refuse the model update (the example still gets saved).

For the model format: scripts/semantic_model/__init__.py (layout) + scripts/semantic_model/models.py. The curation engine is scripts/semantic_model/curate.py. For SQL safety: shared/sql-generation-rules.md. For dialect rules: shared/dialect-rules.md. For DB error classification: shared/db_error_classifier.md.

Phase −1: Plan-mode check

Run the detection + ask logic from shared/plan-mode-check.md. agami-save-correction needs Write (examples + model edits) and Bash (EXPLAIN-validation) — both are blocked in plan mode.

If plan mode is active and the user picks Stay in plan mode (or this skill is invoked under an active plan-mode context): refuse and end the turn. DO NOT write a plan file. DO NOT call ExitPlanMode. Refusal text (verbatim):

I can't save corrections in plan mode — switch to Auto or Edit Automatically mode (Shift+Tab to cycle) and re-invoke. The correction won't persist otherwise.

If plan mode is not active, skip this phase silently and go to Phase 1.

Phase 1: Identify the correction

1a — resolve the active profile and artifacts_dir

Resolve <profile> in this order: AGAMI_PROFILE env var → active_profile field in <artifacts_dir>/local/.config → literal string "default" (legacy fallback).

Resolve <artifacts_dir> per shared/file-layout.md → Configuring artifacts_dir: AGAMI_ARTIFACTS_DIR env var → <artifacts_dir>/local/.config.artifacts_dir → default $HOME/agami-artifacts. All examples / model / ORGANIZATION.md paths in this skill resolve under <artifacts_dir>/<profile>/. USER_MEMORY.md is at <artifacts_dir>/USER_MEMORY.md (top-level, cross-database).

For v1.0 / v1.1 fallback paths (<artifacts_dir>/local/<profile>.yaml, <artifacts_dir>/local/<profile>-examples.yaml, <artifacts_dir>/<profile>/), only read; never write. Migration is agami-connect's job — this skill assumes the user has already migrated by the time they're saving corrections.

1b — find the most recent query

Read the last entry in <artifacts_dir>/local/query_log.jsonl. Need question and sql.

If the log is empty: "I don't have a recent query to attach this correction to. Ask the question first, then save the correction." Stop.

1c — get the corrected SQL

Determine what the user gave:

• They pasted SQL ($ARGUMENTS looks like a SELECT, contains FROM / JOIN / GROUP BY) → use directly as the corrected SQL.
• They described what's wrong ("the join should be on customer_id, not user_id"; "amount is in cents") → regenerate SQL using the semantic model + the original question + their feedback as additional context. Same prompt assembly as query-database Phase 2b.
• No arguments and no recent feedback → ask: "Paste the corrected SQL, or tell me what's wrong with the result."

1d — EXPLAIN-validate the corrected SQL

Run EXPLAIN <sql> (or EXPLAIN QUERY PLAN <sql> for SQLite) via the cached database tool from <artifacts_dir>/local/.config. Same validate-then-save contract as agami-connect/SKILL.md Phase 5b:

• EXPLAIN succeeds → continue.
• EXPLAIN fails → route through shared/db_error_classifier.md. Surface the one-line remediation. Do not save anything. Ask the user to fix the SQL and try again.

Apply shared/sql-generation-rules.md:

• Refuse DDL/DML (DROP, DELETE, INSERT, UPDATE, ALTER, etc.).
• Refuse system-table queries unless the user explicitly asked about schema metadata.

Phase 2: Always append to the examples library

Examples live per subject area at <artifacts_dir>/<profile>/prompt_examples/<area>/examples.yaml. Pick <area> = the subject area whose tables_defined includes the table(s) the corrected SQL references (run bash "$AGAMI_PLUGIN_ROOT/scripts/sm" areas "$ROOT" and match, or get_table_context to confirm membership; if the SQL spans areas, use the area of the primary/driving table).

Use the packaged writer — don't Read/Edit the YAML by hand or grep the source for its schema. It creates the file if absent, appends, and dedups by question (a same-question correction replaces the earlier answer). One entry in a JSON array:

bash "$AGAMI_PLUGIN_ROOT/scripts/sm" add-example "$ROOT" --area <area> --file /tmp/agami-correction-example.json

[{"question": "<original NL question from query_log.jsonl>", "sql": "<corrected SQL>",
  "tables": ["..."], "source": "correction", "status": "confirmed", "created_at": "<ISO8601 UTC>"}]

Required: question, sql. Optional scope tags (improve ranking): tables, columns, metric.

This phase is non-conditional — every correction always lands in the examples library, even if Phase 5 (model update) declines or fails.

Surface: ✓ Correction appended to <artifacts_dir>/<profile>/prompt_examples/<area>/examples.yaml.

Phase 3: Classify the correction

Compare the original SQL (from query_log.jsonl) to the corrected SQL. Identify what the user was teaching us, then route the correction to the right destination. Mis-routing is the most common failure — early-adopter feedback included three real cases where corrections landed in the wrong file:

The decision tree below corrects these failures. Walk it top to bottom — first match wins. Don't fall back to org_context as a default; it's the catch-all that produces the wrong outcome in practice.

Decision tree (top to bottom — first match wins)

Is the correction about a single column's MEANING, UNIT, ENCODING, or VALUE NORMALIZATION?
   (e.g., "amount is in cents", "1 means active not true", "the order total can be
    negative for refunds", "active/ACTIVE/1 all map to 'Active'", "STATUS='1' means active")
   → field_metadata
       → if it's specifically about value → canonical-display mapping, write to
         agami.choice_field on that field.
       → if it's about how the column is interpreted (unit, sign convention,
         encoding), update agami.unit + the field description prose.

Else: is the correction about a JOIN — which columns connect two tables?
   (e.g., "join on customer_id, not user_id"; "products → categories via category_id")
   → relationship

Else: is the correction about what a WHOLE TABLE represents, not one column?
   (e.g., "`orders` includes cancelled rows too", "`metrics_daily` is materialized
    from `events`, use it for date ranges > 7 days")
   → table_metadata

Else: does the corrected SQL define a REUSABLE AGGREGATION that didn't exist?
   (e.g., "MRR = SUM(price) WHERE plan_type='subscription'", "active customers
    means is_active AND last_login > 30 days ago")
   → new_metric
       → if also touches the predicate side (active customers), consider whether
         the predicate alone deserves a named_filter — same Rule 1 sign-off.

Else: is the correction a DISPLAY / FORMATTING / DEFAULT-FILTER preference?
   **Classify it like everything else — don't reflexively ask. Route to the MOST
   SPECIFIC home, structured-model-first:**
   - It's the **currency/unit** of specific column(s) — "amounts are in INR → show ₹",
     "this is a percentage", "values are in days" → set that column's **`unit`** field
     (the ISO currency code, or `percent`/`cents`/`days`) via `cli curate`
     (`{op:edit, kind:table, area, name:<table>, column:<col>, field:unit, value:"INR"}`).
     The runtime + chart renderer format it **deterministically** (`units.py`). This IS
     the org-wide home — it's in the shared model.
   - Another column fact — "amount is in cents" (a scale fix), "this code maps to
     <label>" → `field_metadata`: `value_transform` (`amount/100.0`) or `choice_field`
     on that column. Also in the shared model, org-wide.
   - It's a default filter on a table — "exclude soft-deleted", "tenancy filter" →
     the table's `default_filters` (model), via `cli curate`.
   - It's a cross-cutting presentation convention not tied to one column — "present
     money with lakh/crore grouping" → `user_preference` → `USER_MEMORY.md` (it's a
     presentation rule, not domain meaning; ORGANIZATION.md is narrative-only now).
   - It's a personal stylistic tic that would hold on ANY database — "I like top-10
     not top-5", "my date format" → `user_preference` → `USER_MEMORY.md`.
   Only when you genuinely can't tell personal vs org-wide → **AskUserQuestion** (the
   ambiguity fallback below). Default a currency/unit/data fact to the **model**, not a
   prose file.
   → In all cases, if it changes how SQL renders results (TO_CHAR, ROUND, a symbol),
     ALSO bake it into the affected seed example's SQL so future answers apply it.

Else: is the correction about a BUSINESS TERM specific to this database's domain?
   (e.g., "gold tier means lifetime spend > $10k" — used as a category in many
    queries; "MRR" — the abstract concept; "we don't track refunds, those live
    in Stripe" — what the data fundamentally doesn't include)
   → org_context. A term → `cli set-terminology` (the structured `key_terminology`
     glossary). A higher-level narrative ("we don't track refunds…", "who the users
     are") → an ORGANIZATION.md prose line. See the `org_context` edit section for both.
       → org_context is for ABSTRACT business concepts not tied to one specific
         column. A correction tied to a specific column belongs in field_metadata,
         NOT here. Re-check the first rule of the tree before landing here.

Else: pure SQL syntax / typo with no domain knowledge implied
   (e.g., "missed the GROUP BY", "`customer_idx` is a typo of `customer_id`")
   → sql_fix

Anti-patterns the LLM keeps producing (do NOT do these)

1. Per-column rule → ORGANIZATION.md. "CUSTOMERS.STATUS values normalize to Active" is NOT domain context — it's a column-value mapping. Route to field_metadata (choice_field).
2. Per-column rule → examples.yaml notes. This skill never writes to examples.yaml.notes[] (that path lives in agami-connect Phase 6d). If you find yourself wanting to write "the order total can be negative" as a note on example #12, route it to field_metadata on the actual column instead — the lesson applies to every future query, not just to one example.
3. Dumping a column-fact into a prose file (or USER_MEMORY). "Amounts are in INR → show ₹" is a fact about the amount column → a caveat/value_transform on that column (org-wide, structured, in the shared model) — NOT a USER_MEMORY line and NOT an ORGANIZATION.md prose rule. Route data-facts to the column/table; reserve the prose files for cross-cutting conventions (ORGANIZATION.md) and personal tics (USER_MEMORY). Don't reflexively ask — classify; ask only when personal-vs-org is genuinely unclear.
4. Display preference → prose without changing SQL. If the correction is "always format like X," ALSO modify the seed example's SQL to demonstrate the formatting (so future answers actually apply it, not just describe it).

Diff-based hints (look at SQL changes for classification clues)

• JOIN condition changed → likely relationship.
• Math applied to one column (/100, * 100.0, CAST(...)) → likely field_metadata (with a unit correction).
• CASE WHEN col = 'X' THEN 'Y' ELSE 'Z' END for a column's display value → likely field_metadata with choice_field update.
• New WHERE clause referencing a specific business term (e.g., plan_type='subscription') AND new aggregation → likely new_metric.
• TO_CHAR(...), ROUND(...), AS my_alias, a currency symbol purely on the output side → a display rule. If it's about a specific column (a currency/unit) → that column's caveat/value_transform (model, org-wide). If it's a personal style tic → user_preference. ALSO update the seed example's SQL either way.
• Only structural / cosmetic SQL changes → sql_fix.

When ambiguous, AskUserQuestion (use the rubric above as your option set)

What kind of correction is this?

• A SQL fix — the answer was wrong but the model is fine
• A column meaning change — e.g., amount is in cents, status means something specific, Male/MALE/T all map to "Male"
• A join correction — relationships in the model need updating
• A table meaning change — the description / context for a whole table
• A new business metric — let's add this as a reusable metric
• A display / formatting rule — number formatting, currency/units, default filters (currency/units attach to the column; I only ask about scope if it's genuinely unclear)
• Domain context for this database — abstract business concepts not tied to one column (e.g., "gold tier means lifetime spend > $10k")

The user's answer determines Phase 5 routing.

Distinguishing org_context vs user_preference vs field_metadata:

• If the rule is tied to a specific column → field_metadata. Always check this first.
• Else ask: "would this guidance apply if I connected to a different database?" If yes → user_preference. If no (it's specific to this domain) → org_context.

Phase 4 — surface classification + destination BEFORE Phase 5 writes anything

After classifying, always surface the decision to the user in chat as a one-line summary with explicit reasoning, then proceed with the edit. The contract:

Classification: <kind>
  → routing to: <destination file + the specific field/section that'll change>
  → reasoning: <one sentence explaining which rule of the decision tree matched>

Concrete examples:

Classification: field_metadata
  → routing to: sales/ORDERS.yaml → fields["TOTAL"].description
  → reasoning: rule says "correction about a single column's meaning/encoding/sign convention" — you're teaching that this column can be negative because refunds carry a negative sign.

Classification: field_metadata
  → routing to: sales/CUSTOMERS.yaml → fields["STATUS"].agami.choice_field
  → reasoning: rule says "value normalization mapping (active/ACTIVE/1 → 'Active') belongs in choice_field" — not ORGANIZATION.md.

Classification: user_preference + seed-example update
  → routing to: USER_MEMORY.md (the prose preference) AND examples.yaml example #N (TO_CHAR in SQL)
  → reasoning: "always format counts with commas" is a display preference (cross-DB), and the seed example needs the formatting baked into its SQL so future answers actually apply it.

The user can override before any file is written. If they say "no, that belongs in X instead," re-route to X and re-surface the new classification before proceeding.

Phase 5: Apply surgical model edits (when applicable)

If the correction kind is sql_fix: stop here. Phase 2 already saved the example. Surface the closing message and skip to Phase 6.

For every other kind, you propose a model edit and run the validator BEFORE writing.

4a — propose the edit

Model edits go through the curation engine (semantic_model.cli curate "$ROOT" --ops-file …), which validates + commits + reverts on failure — you don't stage/validate/promote by hand. ROOT="<artifacts_dir>/<profile>". Resolve the subject <area> for an affected table the same way as Phase 2 (the area whose tables_defined holds it). The new-metric case uses cli add --kind metric (curate's --ops-file edits existing entries; add creates them) — same validate + commit + revert guarantees.

Fixing a column/table description marks it human-validated. A correction that rewrites a description via a curate edit op (no source:"ai") automatically sets description_source: "human" — so a description agami had inferred is now trusted and stops surfacing as an "assumption" in answer receipts (see docs/design/validated-through-use-descriptions.md). You don't set description_source yourself; the curate engine does it.

relationship edit

Find the relationship in <area>'s relationships.yaml (by from_table/to_table). The corrected SQL's ON clause tells you the fix:

• Different columns → edit op setting from_column / to_column (or, for a CAST/compound join, set on: and null out from_column/to_column — the "approve with fix" shape).
• Missing relationship → write a new entry into relationships.yaml (unique by from/to), with the required relationship: cardinality inferred from the join (many_to_one unless the keys are both unique), then cli validate.
• Spans two areas → it's a cross_subject_area_relationship (org-level cross_subject_area_relationships.yaml), with from_subject_area/to_subject_area + executable.
• Reverses direction → ask before flipping. Never delete a relationship unless the user explicitly says "remove the relationship".

table_metadata edit

edit op(s) on the table: set description (what the table represents) or append a caveats[] entry (a usage note / quirk). Never change grain, columns, source_type, or relationships from a table-metadata correction — those are structural.

field_metadata edit

edit op(s) on the column (kind: table, area, name: <table>, column: <col>):

• Set description ("Order amount in cents.").
• A unit / data-quality note → append a caveats[] entry ("Amounts in cents; divide by 100 for dollars.").
• An enum mapping ("status 1 = active, 0 = inactive") → set choice_field.
• A cleaning rule ("strip the brackets") → set value_transform (must parse as SQL — the validator checks). Never set a column's structural identity from a field-metadata correction.

new_metric edit

Write subject_areas/<area>/metrics/<name>.yaml (snake_case name, unique in the area):

name: <derived_from_user_request>
calculation: <one-sentence prose intent — REQUIRED, never empty>
bindings:
  <storage_type>: <the aggregation SQL from the corrected SQL>
source_tables: [<tables it reads>]
other_names: [<the user's term + obvious variants>]
confidence: proposed
review_state: unreviewed

Reference columns plainly (<table>.<column>). Strip user-specific WHERE filters (WHERE customer_id = 42); keep only definitional ones (WHERE plan='subscription'). Then cli validate "$ROOT". A proposed/unreviewed metric needs sign-off on the /agami-model Review tab before the runtime will use it (Rule 1) — tell the user.

user_preference edit

A user_preference correction does NOT touch the semantic model. It lands in <artifacts_dir>/USER_MEMORY.md (per shared/user-memory-format.md) — the global preferences file that applies across every database. Steps:

1. Read <artifacts_dir>/USER_MEMORY.md (it exists — init seeds it).
2. Pick the right section (Default filters, Naming and synonyms, Display preferences, or Avoid) based on the policy's nature. Add a new section if none of the four fits — keep this rare.
3. Append the new bullet under that section, in plain English (the user's wording, lightly cleaned). Don't paraphrase aggressively — preserve their voice.
4. Show the user the diff (per Phase 4b below) before writing.
5. Strip nothing — USER_MEMORY.md is intentionally free-form, not schema-validated. The validator (Phase 4c) is a no-op for user_preference corrections; the semantic model is unchanged.

The user's bullet should be self-contained — anyone reading USER_MEMORY.md should understand the policy without seeing the original conversation.

org_context edit

org_context splits by what kind of fact it is — each goes to its proper home (per shared/organization-context-format.md). The two homes are deliberately separate; never write one kind into the other.

• A term's meaning (the common case) — "gold tier" = lifetime spend > $10k, "MRR" = monthly recurring revenue, or an acronym → its expansion. This goes to the structured glossary, NOT a prose file — set-terminology merges it onto key_terminology (validated, committed), and it then surfaces in the derived domain context on every query automatically (no file to re-render, nothing for a human to clobber):

  printf '{"gold tier": "lifetime spend > $10k"}' > /tmp/agami-term.json
  bash "$AGAMI_PLUGIN_ROOT/scripts/sm" set-terminology "$ROOT" --file /tmp/agami-term.json
  

  The key is the term; the value is a self-contained definition (understandable without the original conversation). It merges by default — existing terms are never lost. Never hand-append - "term" = definition lines to ORGANIZATION.md; that's the old prose home and is wrong now.
• A higher-level narrative — what the data represents, who the users are, what's not in this database. Append a sentence/paragraph to <artifacts_dir>/<profile>/ORGANIZATION.md under # About this database (create it with the starter if missing — cli org-draft "$ROOT" > "$ROOT/ORGANIZATION.md"). This file is the human narrative only — no term = definition lines, no model facts.
• A cross-cutting display/formatting convention (a currency symbol or number grouping everyone querying this DB should see) is a presentation preference, not domain meaning: route it to user_preference → USER_MEMORY.md, or — when it's really a fact about one column (units/currency) — to that column's caveat/value_transform. Do not invent an ORGANIZATION.md "conventions" heading; the file is narrative-only.

Show the user the diff (Phase 4b) before writing. set-terminology is validated (reverts on failure); ORGANIZATION.md prose is free-form (no validation).

mixed edit

Apply each individual edit as above. Show the user the combined diff in 4b before validating. If the mix includes a user_preference or org_context, those parts skip the validator (USER_MEMORY.md / ORGANIZATION.md aren't validated); the semantic-model parts still go through the validator.

4b — show the diff to the user, get approval

Build a unified diff (or a compact "before / after" summary) of the proposed change against the existing target file. Name the file in the prompt so the user knows what they're approving. Show via AskUserQuestion:

I want to update the target file in `//subject_areas//:

[Relationship] orders_to_customers
- from_columns: [user_id]
+ from_columns: [customer_id]

Approve?

• Yes (Recommended) — apply and validate
• No — leave the model as-is, the example is still saved
• Edit first — let me tweak before applying

For org_context / user_preference the file is ORGANIZATION.md / USER_MEMORY.md instead of a schema yaml — same prompt shape, just a different filename.

Always include the validator step in 4c regardless of which option they pick (since "Yes" still has to validate, except for ORGANIZATION.md / USER_MEMORY.md which aren't validated).

4c — apply with validation (the gate)

For relationship / field_metadata / table_metadata edits (existing entries): build the ops array, write it with the Write tool (never a heredoc / shell variable / python3 -c — JSON quotes and null break those), then apply via the curation engine — it validates the whole model, commits to the profile git repo, logs to curation_log.jsonl, and reverts every change if validation fails:

bash "$AGAMI_PLUGIN_ROOT/scripts/sm" curate "$ROOT" --ops-file /tmp/agami-correction-ops.json

Stdout: {applied, skipped, errors, validated, committed}.

• validated: true → surface ✓ Model updated and validated.
• validated: false → the engine already reverted; surface errors verbatim: "Your correction would break the model — here's what's wrong: …. The example is saved either way; the model wasn't updated."

For new_metric (creating an entry): use the packaged add command — don't hand-write the YAML. It validates the item + the whole tree, writes subject_areas/<area>/metrics/<slug>.yaml, reverts on failure, and commits. Put the one metric in a JSON array:

bash "$AGAMI_PLUGIN_ROOT/scripts/sm" add "$ROOT" --kind metric --area <area> --file /tmp/agami-new-metric.json

Same {applied, skipped, errors, validated, committed} contract as above: validated: false → it already reverted, surface errors; skipped → the metric was structurally invalid (e.g. missing calculation), surface the reason.

There is no override path — a model that fails validation is never persisted; <artifacts_dir>/<profile>/ is left unchanged. The example library still got the correction (Phase 2 already happened).

For org_context / user_preference corrections (ORGANIZATION.md / USER_MEMORY.md only): no validator step. Write the file directly with chmod 600.

4d — confirmation

✓ Correction appended to <artifacts_dir>/<profile>/prompt_examples/<area>/examples.yaml
✓ Model updated in <artifacts_dir>/<profile>/subject_areas/<area>/:
    - relationship orders_to_customers from_columns: [user_id] → [customer_id]
✓ Validator passed.

Next time someone asks "<question>" or anything similar, I'll use the corrected SQL AND know the right join is on customer_id.

(Phase 6 — telemetry emission on correction — has been removed in the current 0.x line. The skill no longer reads analytics_consent and no longer appends to .telemetry-queue.jsonl. agami has no telemetry — see docs/privacy.md.)

Edge cases

• Empty examples file — initialize it with the new entry as the only one.
• examples.yaml missing — invoke agami-connect first to seed, then append.
• User pastes SQL referencing tables not in the model — EXPLAIN-validate catches it (table_not_found); surface the remediation, don't save.
• User saves a duplicate of an existing seed — replace the seed (source: correction, fresh created_at).
• Most-recent query is itself a correction — that's fine, attach to it.
• Validator fails on a model edit but the user really wants it saved — they can hand-edit <artifacts_dir>/<profile>/<schema>.yaml directly and the next query-database will (try to) read it. The validator runs again from connect verify if they want to confirm. There is no "skip validation" path from this skill.
• User says "actually undo my last correction" — they hand-edit the YAML / Markdown files; this skill doesn't track an undo log in v1.
• Edit affects datasets in two different schemas — split into two separate edits, one per target file. The validator runs once per write (or once for the merged directory).

Hard rules

1. Phase 2 (examples append) always runs. Even if the user later changes their mind on the model edit, the example is already saved.
2. Phase 5 model writes are gated by the validator. cli curate (edits existing entries) and cli add (creates a new metric/entity) are the only ways to write inside <artifacts_dir>/<profile>/, and both refuse / revert on a validation failure. No exceptions. ORGANIZATION.md and USER_MEMORY.md edits skip the validator (free-form Markdown).
3. Edits stay valid against the model. Don't invent fields — the Pydantic models (scripts/semantic_model/models.py) forbid unknown keys, so an invalid edit is rejected by the validator. When you can't express a correction within the model shape, fall back to sql_fix (example only) and tell the user "I can save this as a few-shot example but it doesn't fit a model edit."
4. Show the diff before mutating the model. The user always gets to see and approve the proposed change.
