In F1, F2-with-memories and F5 the phase closes + with the deliberate `reviewer_confirm kind:"phase"` summary gate. The `advance:true` + flag on `reviewer_decide` is a shortcut that auto-advances ONLY F2 when the memory phase + recorded nothing and F6 when it is skipped/empty; everywhere else it is a silent no-op, + so never rely on it to advance. The self-closing mechanisms are the five listed above + (F3 `rewrite_question`, F4 final schema persistence, F6 last + `kind:"cte_result"`, F7 `kind:"sql"`, F8 `reviewer_memory_promote`) — after one of + those, do NOT add a `reviewer_confirm kind:"phase"` that merely echoes it; the phase is + already closed. +3. **Single pick vs multi-answer.** For a single-pick clarification or decision, use + `reviewer_select` and attach a `decision` payload (`{type, subject, detail?, + rationale?}`) to each concrete option: picking it persists that decision directly — + no follow-up `reviewer_decide`/`reviewer_confirm`. Options WITHOUT a payload only + ask (use for pure iteration before you commit). For genuinely multi-answer + decisions (several options simultaneously true) use `reviewer_decide` (multiselect). +4. **"Accept the proposal" is always an option.** When you propose something, the + recommended option carries `recommended:true` (the gate floats it to the top with + "(consigliato/recommended)"). "Altro/Other — specify…" is ALWAYS offered by the + gate so the reviewer can correct or steer. Never force your recommendation. +5. **No step in limbo.** Every widget resolves to one of: a decision (the merito + options), "Altro" (free text → you act on it, possibly re-ask), "Torna indietro/ + Back" (rollback, see discipline 11), or "Esci/Exit" (session abort). If the + reviewer closes without choosing, the gate re-presents the same widget — there is + no silent skip. +6. **Self-contained messages.** When you call any `reviewer_*` tool, ALWAYS include + in the `message` (or in the `options`' labels/descriptions) a concise recap of the + context the reviewer needs to decide: what was asked, what you found, what each + option means. The reviewer does not see your internal reasoning — only the widget. + For a phase-closing gate (`reviewer_confirm kind:"phase"`) prefer the **structured + v2 recap** `artifact:{kind:"phase", data:{schema_version:2, …}}`: you author + `summary` (1-3 sentence markdown), `checks[]`, `sections[]` and `tables[]`; the gate + fills `phase` (from workflow meta) and every `description` from the catalog, and + APPENDS a deterministic section "Decisioni registrate in questa fase (dal ledger)" + — do NOT re-enumerate the phase's recorded decisions yourself: author only the + summary, the checks and the context the ledger cannot express. Every + `sections[].items[]` MUST cite the concrete **table**, **column** and the **value** + that motivates the choice (booleans, time windows, thresholds) — not just prose. + Compact example: + ```json + {"schema_version":2,"summary":"Selezionati pazienti attivi con ricoveri nel 2023.", + "checks":[{"label":"schema_linking valido","status":"ok"}], + "sections":[{"title":"Criteri di selezione","items":[ + {"label":"solo pazienti attivi","table":"dim_patient","column":"flag_attivo", + "value":"IS TRUE","kind":"filter","rationale":"esclude i cessati"}, + {"label":"finestra temporale","table":"dim_time","column":"year", + "value":"= 2023","kind":"filter","rationale":"anno richiesto"}]}], + "tables":[{"name":"dim_patient","role":"promoted", + "columns":[{"name":"cod_paz","value_filter":""}]}], + "open_questions":[]} + ``` + `open_questions` MUST be an array of plain strings (`string[]`). Never put objects + such as `{label, question}` in it; express each open question as one complete string. + Legacy free-text recaps still work (no `schema_version`), but prefer v2. Note: the + F4 schema-linking recap travels in `tables` of this v2 phase payload — do NOT reuse + `kind:"schema_linking"` for a phase recap. +7. **Artifact = first-class output.** `schema_linking.json`, `cte_plan.json`, + `ctes/*.sql`, `sql_final.sql` are produced and reviewed explicitly, never hidden. + For a v2 `kind:"cte_result"` gate the gate **rebuilds the artifact from + deterministic sources** (`tht cte info`: the persisted `.sql` + the last CTE + test record) — you send only the thin `{purpose?, rationale?, note?}` and the + reviewer approves the gate-built payload, not your text. For final SQL + (`kind:"sql"`) the gate reads `sql_final.sql` from disk and shows it integral. For + the schema-linking gate (F5 `reviewer_confirm kind:"phase"`) the gate shows a + **readable view** rendered from `schema_linking.json`. Write the artifacts with + care; they are the decision surface. +8. **Candidates are candidates, not truth.** Present LSH/vector/evidence matches with + their **provenance** (LSH / vector / evidence) and their scores, never as absolute + truth. The reviewer may reject them. Verify filter values with `tht search find + ""` (real-value match) before baking them into SQL. +{{DISAMBIGUATION_OPEN_AMBIGUITY}} +10. **Free-text (D13).** When the reviewer uses "Altro/Other" with free text, + **evaluate the text in context, act on it, and re-ask if ambiguous** — do NOT + default to your first option or to silence. Record the reviewer's words verbatim + in the decision `rationale`. +11. **Rollback (D15).** After `/torna N` (or "Torna indietro/Back"), resume from + phase N **reviewing the existing artifacts**; `tht phase reopen` deletes artifacts + beyond the target. Do NOT re-run `tht` commands for artifacts that are still valid. +12. **This skill is the complete contract.** Every command, flag and behavior you + need is named in this skill and its reference docs (`rewriting.md`, `cte.md`, + `sql-generation.md`). Do NOT run `--help`, do NOT read the harness source + (`tht/`, `.pi/extensions/`, tests) to figure out how a command works, and do NOT + explore the filesystem with `find`/`grep`/`cat` for that purpose. If something + genuinely seems missing or a command behaves unexpectedly, say so to the reviewer + instead of reverse-engineering the tooling. + +## Phase 0 — Resume (cold start) + +When launched with `/riprendi-sessione ` you have NO prior conversation — the +persisted state is your only context. Bootstrap before doing anything else: + +1. `tht session show --json` → read `phase` (the current phase N), `status`, and + the manifest (`question`, `database`, `schema`). +2. Load the artifacts produced so far with `tht session documents --json`, which + returns their keys and contents directly: `question.md` (revised question), + `schema_linking.json` (F4 output), `ctes/*.sql` + `cte_tests.json` (F6), + `sql_final.sql` (F7). The decision ledger is summarized by `tht session show`. + **Non cercare i file fisici con `find`, `ls`, `cat` o il generic read tool**: the + session repository may live outside the checkout and the documents command is the + canonical read boundary. +3. **Resume at phase N reviewing the existing artifacts** (same discipline as rollback, + §Disciplines 11).

(The backend already refuses resume for finalized/archived sessions.) + +{{DISAMBIGUATION_INSTRUCTIONS}} + +{{MEMORY_INSTRUCTIONS}} + +{{DISAMBIGUATION_REWRITING_INSTRUCTIONS}} + +## Phase 4 — Schema linking + +Prerequisite: Phase 3 closed. + +1. `tht schema render --format mschema-text` for the schema context (the catalog + `artifacts/mschema/physical.yaml` is already in the workspace; only if render fails + with `physical.yaml non trovato`, run `tht schema introspect` once, then render). + To inspect specific tables use `--table ` (repeatable: `-t t1 -t t2`) — + do NOT dump the full catalog or slice it with `awk`/`grep`. The session's + `retrieval_pack.md` (built in F1) already lists the candidate tables for the + question — start from those. + Copy table/column names EXACTLY from it — never invent objects. +{{MEMORY_SOLVED_SEARCH_F4}} +2. Propose tables to promote/exclude with **`reviewer_schema_linking`**: pass + `tables[]` as `{id, name, kind: "promote"|"exclude", rationale, suggested_columns}`. + Do NOT list every column yourself — the gate loads the full column set (with + descriptions) from the catalog and pre-selects your `suggested_columns`. The + reviewer curates the columns per promoted table. The tool records + `table_promoted`/`table_excluded` + `column_promoted`/`column_excluded` and + re-projects `schema_linking.json` deterministically via `tht session + sync-schema-linking` (you do NOT hand-write the tables/columns part with + `write_schema_linking`). The promoted columns are the reviewer-approved OUTPUT + columns: project exactly those in the final SELECT (Phase 6/7); you remain free + to reference other columns as join keys or filter predicates when the query + requires them. + Call `reviewer_schema_linking` before the join review. For a multi-table plan, + `advance:true` will report that F4 remains open because the structured joins are + not present yet; this is expected. Stay in F4 and continue with the join-only gate. + Propose **all required joins together in a separate, join-only** + `reviewer_decide(advance:false)`, registering `join_modified`. Do not mix + `join_modified` with other decision types in that call. The gate renders this proposal + as read-only information: **Continue records every proposed join**; the reviewer cannot + remove individual joins (which could create an accidental Cartesian product). The complete + set is persisted atomically under a per-session writer lock: an invalid response or write + failure records none of it. If the reviewer uses **Other — specify**, none of the current + joins is recorded: incorporate the textual correction and present the complete revised join + set again. + Ground joins in the `【Foreign keys】` section of the mschema-text + render: it lists the curated logical FKs of the workspace (e.g. + `fact_x.cod_paz=dim_patient.cod_paz`, `*_time_key=dim_time.day_key`) — prefer + those to joins you derive yourself, and flag to the reviewer any join you need + that is NOT in the list. +{{DISAMBIGUATION_SCHEMA_GROUNDING}} +5. Persist the **joins** (and any `concept_formulas`/`open_questions`) with the gate's + `write_schema_linking` tool — it validates the object against the `SchemaLinking` + model and writes the file deterministically (never hand-write it, never edit it + with the file tool; on a validation error the tool returns the exact problem to + fix). Shape: `{question, candidates:[...], joins:[{from, to, source?}], + excluded:[...], open_questions:[], concept_formulas:[]}` — `candidates`/`excluded` + are owned by `reviewer_schema_linking`/`sync-schema-linking` (step 2), so if you + call `write_schema_linking` after step 2, carry over its `candidates`/`excluded` + unchanged rather than overwriting them. After the reviewer-approved joins are present, + `write_schema_linking` closes F4 automatically. Do not add a `reviewer_confirm + kind:"phase"`. Do NOT run `tht session check` (that's Phase 5). + +## Phase 5 — Synthesis + +Prerequisite: Phase 4 closed; `schema_linking.json` present. + +1. `tht session check` (objective gate: decisions present + schema_linking valid). +2. Summarize the schema-linking to the reviewer; if corrections are needed, reopen + Phase 4. +3. Close with `reviewer_confirm kind:"phase"`. + +## Phase 6 — CTE plan + +Prerequisite: Phase 5 closed. + +1. Read `cte.md`. Decompose the rewritten question into CTEs (Agent View Generation): + each CTE captures an informative subset with a clear purpose, named in snake_case. +{{MEMORY_SOLVED_SEARCH_F6}} +2. Present the full CTE plan to the reviewer with `reviewer_confirm kind:"cte_plan"`, + passing a **structured v2 artifact** (`artifact:{kind:"cte_plan", data:{…}}`). You + author `question`, `strategy` and each `ctes[]` entry (`name`, `purpose`, + `rationale`, `depends_on`, `tables[].name`, `keys`, `filters[]` with + `column`/`op`/`value`/`rationale`, `output_columns`); the gate fills `index` + (1-based) and every `description` from the catalog, derives the ordered `--name` + list from `data.ctes[].name`, and on approval persists both `cte_plan.json` and the + chain doc (`cte_plan_doc.json`). Compact example (2 CTE): + ```json + {"schema_version":2,"question":"pazienti attivi con almeno un ricovero nel 2023", + "strategy":"prima la base dei pazienti attivi, poi i loro ricoveri filtrati per anno", + "ctes":[ + {"name":"base_pazienti","purpose":"pazienti attivi","rationale":"insieme di partenza", + "depends_on":[],"tables":[{"name":"dim_patient"}],"keys":["cod_paz"], + "filters":[{"column":"dim_patient.flag_attivo","op":"IS","value":"TRUE","rationale":"solo attivi"}], + "output_columns":["cod_paz"]}, + {"name":"ricoveri_2023","purpose":"ricoveri dei pazienti nel 2023","rationale":"restringe al 2023", + "depends_on":["base_pazienti"],"tables":[{"name":"fact_ricoveri"}],"keys":["cod_paz"], + "filters":[{"column":"dim_time.year","op":"=","value":"2023","rationale":"finestra temporale"}], + "output_columns":["cod_paz","data_ricovero"]} + ]} + ``` +3. For each CTE (in plan order): call `write_cte_sql` with the session id, CTE name, + and SQL block (the tool invokes `tht cte save --session --name --file -`). + Persist ONLY the + `WITH ... AS (...)` block, NO trailing SELECT), test with `tht cte test --session + ` (with an **ok** outcome), then present it with + `reviewer_confirm kind:"cte_result"`. Pass ONLY the thin v2 data + `artifact:{kind:"cte_result", data:{schema_version:2, purpose?, rationale?, note?}}` — + NEVER paste SQL, columns or preview rows as text: the gate reads them + deterministically from `tht cte info` (the persisted `.sql` + the last test + record) and builds the full artifact the reviewer approves. The next CTE is testable + ONLY after the previous one is approved (CLI exit 5 if out of order). Copy + table/column names EXACTLY from the schema context; use values verified with + `tht search`. +4. After the last CTE is approved, close with `reviewer_confirm kind:"phase"`. + +## Phase 7 — Final SQL + +Prerequisite: Phase 6 closed. + +1. Read `sql-generation.md`. Recursive divide-and-conquer: the CTEs approved in + Phase 6 are the preferred building blocks (reuse them by name). +{{MEMORY_SOLVED_SEARCH_F7}} +2. Compose the final SQL (PostgreSQL dialect, exact names from the schema context). + **Output columns (F4 honoring).** The columns promoted in Phase 4's + `schema_linking.json` are the reviewer-approved OUTPUT columns: project exactly + those in the final SELECT. Other schema-linked columns remain usable as join + keys or filter predicates, but do not add them to the SELECT list. + **Time dimension:** `data_time_key` is the FK to `dim_time.day_key` (NOT declared + in the DWH, must be added by hand to the join); use `JOIN dim_time` and its + columns (`dt.year`, `dt.month`, …), NEVER arithmetic on the key. +3. `tht sql validate` + `tht sql preview` (max 10 rows). On errors / suspicious + results, apply the `sql-generation.md` checklist and correct with the reviewer. +4. Call `write_final_sql` with the session id and clean SQL; it invokes + `tht sql set-final --session --file -` (ONLY clean SQL, no comments). + Approve with `reviewer_confirm kind:"sql"` (records `sql_approved`), then advance to + Phase 8 with `reviewer_confirm kind:"phase"` — `kind:"sql"` alone does NOT advance F7. + +## Phase 8 — Datamart + +Prerequisite: Phase 7 closed. + +1. Call `reviewer_datamart` with the session id. This gate is deployment-aware and is + the ONLY allowed way to record the datamart choice: + - `THT_PROFILE=workstation`: it records `datamart_declined` automatically and shows + no question to the reviewer; + - `THT_PROFILE=server` (including the default): it always shows both choices, + "Sì, genera il datamart" and "No, salta il datamart", and records the selected one. + Never replace this gate with a hand-built `reviewer_select`. +2. On a server, if the reviewer chose yes: `tht datamart generate` (stub — raises + NotImplementedError for now). Tell + the reviewer that dbt generation is not implemented yet. +{{MEMORY_PROMOTION_F8}} + +## Session end + +When the promotion gate (or, as fallback, the F8 phase gate) closes Phase 8, the +gate calls `tht session finalize` automatically. +{{MEMORY_SOLVED_FINALIZATION}} +state (ledger `review_decisions.jsonl` + artifacts) is the truth: what is not +recorded did not happen. diff --git a/harness/tests/test_pi_skill_projection.py b/harness/tests/test_pi_skill_projection.py new file mode 100644 index 00000000..1d14598f --- /dev/null +++ b/harness/tests/test_pi_skill_projection.py @@ -0,0 +1,53 @@ +import hashlib + +import pytest + +from tht.pi_skill_projection import ( + FRAGMENT_ORDER, + PROJECTION_PATH, + projection_is_current, + render_projection, +) + + +BASELINE_SHA256 = "626a794071c095a4f20fffabb3bab901f05c101590adbdc58e45adfae56f3219" + + +def test_modular_pi_skill_renders_the_byte_identical_approved_projection(): + rendered = render_projection() + + assert FRAGMENT_ORDER == ( + ("{{DISAMBIGUATION_OPEN_AMBIGUITY}}", "disambiguation/open-ambiguity.md"), + ("{{DISAMBIGUATION_INSTRUCTIONS}}", "disambiguation/phase-1.md"), + ("{{MEMORY_INSTRUCTIONS}}", "memory/phase-2.md"), + ("{{DISAMBIGUATION_REWRITING_INSTRUCTIONS}}", "disambiguation/phase-3.md"), + ("{{MEMORY_SOLVED_SEARCH_F4}}", "memory/solved-search-f4.md"), + ("{{DISAMBIGUATION_SCHEMA_GROUNDING}}", "disambiguation/schema-grounding.md"), + ("{{MEMORY_SOLVED_SEARCH_F6}}", "memory/solved-search-f6.md"), + ("{{MEMORY_SOLVED_SEARCH_F7}}", "memory/solved-search-f7.md"), + ("{{MEMORY_PROMOTION_F8}}", "memory/phase-8-promotion.md"), + ("{{MEMORY_SOLVED_FINALIZATION}}", "memory/solved-finalization.md"), + ) + assert rendered == render_projection() + assert hashlib.sha256(rendered).hexdigest() == BASELINE_SHA256 + assert PROJECTION_PATH.read_bytes() == rendered + + +def test_projection_check_detects_stale_output(tmp_path): + stale = tmp_path / "SKILL.md" + stale.write_bytes(b"stale\n") + + assert projection_is_current(stale) is False + + +def test_projection_rejects_a_missing_or_repeated_static_placeholder(): + with pytest.raises(ValueError, match="exactly once"): + render_projection(template=b"{{MEMORY_INSTRUCTIONS}}\n") + with pytest.raises(ValueError, match="exactly once"): + render_projection( + template=( + b"{{DISAMBIGUATION_INSTRUCTIONS}}\n" + b"{{MEMORY_INSTRUCTIONS}}\n" + b"{{MEMORY_INSTRUCTIONS}}\n" + ) + ) diff --git a/harness/tht/pi_skill_projection.py b/harness/tht/pi_skill_projection.py new file mode 100644 index 00000000..aa5e418a --- /dev/null +++ b/harness/tht/pi_skill_projection.py @@ -0,0 +1,70 @@ +"""Deterministic builder for the single Pi-facing Thoth session skill.""" + +import argparse +from pathlib import Path +import sys + + +HARNESS_ROOT = Path(__file__).resolve().parents[1] +SKILL_ROOT = HARNESS_ROOT / ".pi" / "skills" / "tht-sessione" +MODULE_ROOT = SKILL_ROOT / "modules" +TEMPLATE_PATH = SKILL_ROOT / "projection.md.tmpl" +PROJECTION_PATH = SKILL_ROOT / "SKILL.md" + +# This tuple is the composition contract.
