fix: correct inference log format, align openenv.yaml task IDs, harden Dockerfile

Browse files

- inference.py: replace JSON stdout with hackathon-spec flat key=value format
([START] task=... env=... model=..., [STEP] step=... reward=0.00 ...,
[END] success=... score=... rewards=r1,r2,...); add try/finally so [END]
always emits; add max_tokens=300; fallback approve on LLM failure
- openenv.yaml: replace 3 wrong placeholder IDs with all 15 actual task IDs
(easy_001–005, medium_001–005, hard_001–005)
- Dockerfile: add curl + HEALTHCHECK --interval=30s; curl -f /health probe
- README.md: add HF openenv tag, Why This Matters section, reward/baseline tables
- server/environment.py: fix task.schema → task.schema_info (AttributeError on
request_more_context action)
- tests/test_reward.py: new file — 13 unit tests for all compute_reward() branches
- tests/test_api.py: add request_more_context regression test
- tests/test_inference.py: update run_episode assertion to match new return type
and log format

All 27 tests pass.

  # SQL Query Reviewer
11
 
12
- `Meta-hackathon` is the GitHub source repo for `sql-query-reviewer`, an OpenEnv-style environment where an agent reviews SQL queries for correctness, performance, and security issues.
13
 
14
- The same repository is designed to work in both places:
15
- - GitHub is the canonical source, CI surface, and collaboration home.
16
- - Hugging Face Spaces runs the Dockerized FastAPI environment directly from this repo layout.
17
 
18
  ## What The Environment Does
19
 
20
  Each episode gives the agent:
21
- - a SQL query
22
- - schema context when it matters
 
23
  - a short explanation of the query's intended purpose
24
 
25
  The agent responds step by step with one of four actions:
26
- - `identify_issue`
27
- - `suggest_fix`
28
- - `approve`
29
- - `request_more_context`
30
 
31
- Rewards are deterministic and shaped for partial progress:
32
- - correct issue identification earns severity-weighted reward
33
- - valid fixes earn bonus reward
34
- - false positives are penalized
35
- - approving with missed issues is penalized

54
  ## Task Bank
55
 
56
- The environment ships with 15 tasks:
57
- - 5 easy syntax and basic logic reviews
58
- - 5 medium schema-aware performance reviews
59
- - 5 hard security and advanced optimization reviews
60
 
61
- Task data lives in:
62
- - `tasks/easy_tasks.json`
63
- - `tasks/medium_tasks.json`
64
- - `tasks/hard_tasks.json`
 
65
 
66
- ## Local Development
67
 
68
- Install dependencies:
69
 
70
- ```bash
71
- python -m venv .venv
72
- .venv\Scripts\activate
73
- python -m pip install --upgrade pip
74
- python -m pip install -e .[dev]
75
- ```
76
 
77
- Run the API locally:
 
 
 
 
 
 
 
78
 
79
- ```bash
80
- uvicorn server.app:app --reload --port 8000
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
81
  ```
82
 
83
- Smoke-test the API:
84
 
85
  ```bash
86
- curl -X POST http://localhost:8000/reset -H "Content-Type: application/json" -d "{\"task_id\":\"easy_001\"}"
87
- curl http://localhost:8000/state
 
 
88
  ```
89
 
90
- Run tests:
91
-
92
  ```bash
 
 
93
  pytest
94
  ```
95
 
96
- Build the container:
97
 
98
  ```bash
99
  docker build -t sql-query-reviewer .
100
  docker run -p 8000:8000 sql-query-reviewer
101
  ```
102
 
103
- ## Inference Script
104
-
105
- `inference.py` uses the OpenAI Python client against any OpenAI-compatible endpoint.
106
-
107
- Expected environment variables:
108
 
109
  ```bash
110
- set ENV_BASE_URL=http://localhost:8000
111
- set API_BASE_URL=https://router.huggingface.co/v1
112
- set MODEL_NAME=Qwen/Qwen2.5-72B-Instruct
113
- set HF_TOKEN=hf_xxx
114
  python inference.py
115
  ```
116
 
117
- The script emits structured logs using:
118
- - `[START]`
119
- - `[STEP]`
120
- - `[END]`
121
 
122
  ## Hugging Face Spaces
123
 
124
- This repo is Space-ready because:
125
- - the README starts with Hugging Face YAML front matter
126
- - the repo includes a root `Dockerfile`
127
- - the API listens on port `8000`
128
-
129
- Recommended setup:
130
- 1. Create a new Space at `https://huggingface.co/new-space`
131
- 2. Set owner to your Hugging Face namespace, name to `sql-query-reviewer`, and SDK to `Docker`
132
- 3. In GitHub, add repository secret `HF_TOKEN` with a Hugging Face token that can write to Spaces
133
- 4. In GitHub, add repository variable `HF_SPACE_ID` with the exact repo id, for example `hellinferno/sql-query-reviewer`
134
- 5. Push to `main` or run the `Sync To Hugging Face` workflow manually from the Actions tab
135
-
136
- Using `HF_SPACE_ID` is the safest option because your Hugging Face namespace may not match your GitHub owner name exactly.
137
-
138
- To deploy manually from a local machine with git:
139
 
140
  ```bash
141
- git remote add hf https://huggingface.co/spaces/<hf-username>/sql-query-reviewer
142
  git push hf main
143
  ```
144
 
145
- If you install the OpenEnv CLI, you can also use:
146
-
147
- ```bash
148
- python -m pip install "git+https://github.com/meta-pytorch/OpenEnv.git"
149
- openenv push --repo-id <hf-username>/sql-query-reviewer
150
- ```
151
-
152
- ## GitHub Actions
153
-
154
- CI runs tests and a Docker build on pushes and pull requests.
155
-
156
- The Hugging Face sync workflow expects:
157
- - GitHub secret `HF_TOKEN`
158
- - optional GitHub variable `HF_SPACE_ID`
159
-
160
- If `HF_SPACE_ID` is not set, the workflow defaults to:
161
-
162
- ```text
163
- <lowercased-github-repository-owner>/sql-query-reviewer
164
- ```
165
-
166
  ## Usage Example
167
 
168
  ```python
169
  from sql_query_reviewer import SQLReviewAction, SQLReviewEnv
170
 
171
- with SQLReviewEnv(base_url="http://localhost:8000").sync() as env:
172
  result = env.reset(task_id="easy_001")
173
- result = env.step(
174
- SQLReviewAction(
175
- action_type="identify_issue",
176
- issue_category="syntax",
177
- issue_description="SELCT is misspelled and should be SELECT",
178
- suggested_fix="SELECT * FROM users WHERE id = 1;",
179
- confidence=0.98,
180
- )
181
- )
182
  print(result.reward)
183
  print(result.observation.feedback)

  # SQL Query Reviewer
13
 
14
+ An OpenEnv environment where an AI agent reviews SQL queries for correctness, performance, and security — the same task thousands of engineers perform every day in code reviews, migration scripts, and ETL audits.
15
 
16
+ ## Why This Matters
17
+
18
+ SQL bugs are among the most common and costly defects in production systems. A misplaced keyword breaks an API, a missing index degrades latency by 100x, and an unsanitized input opens a door to data exfiltration. Today these defects are caught by human reviewers who spend hours on repetitive pattern matching. This environment provides a standardized benchmark to train and evaluate AI agents that can automate this critical workflow — directly useful for developer tools, IDE integrations, and automated code review systems.
19
 
20
  ## What The Environment Does
21
 
22
  Each episode gives the agent:
23
+
24
+ - a SQL query (with realistic bugs drawn from production patterns)
25
+ - schema context when it matters (table definitions, column types, constraints)
26
  - a short explanation of the query's intended purpose
27
 
28
  The agent responds step by step with one of four actions:
 
 
 
 
29
 
30
+ | Action | Description |
31
+ |---|---|
32
+ | `identify_issue` | Flag a correctness, performance, or security problem |
33
+ | `suggest_fix` | Propose corrected SQL for a previously identified issue |
34
+ | `approve` | Mark the query as acceptable (ends episode) |
35
+ | `request_more_context` | Ask for additional schema information |
36
 
37
+ ## Reward Design
38
 
39
+ Rewards are deterministic and shaped for partial progress throughout the trajectory:
40
+
41
+ - **Correct issue identification**: +0.10 to +0.35 scaled by issue severity
42
+ - **Valid fix suggestion**: +0.08 to +0.10 bonus
43
+ - **Confidence bonus**: up to +0.05 for high-confidence correct identifications
44
+ - **False positive**: −0.10 penalty
45
+ - **Duplicate identification**: −0.02 penalty
46
+ - **Approving with missed issues**: −0.15 per missed issue
47
+ - **Complete correct approval**: +0.20
 
 
 
 
 
48
 
49
  ## Task Bank
50
 
51
+ The environment ships with **15 tasks** across three difficulty levels:
 
 
 
52
 
53
+ | Difficulty | Count | Examples | Expected Baseline Score |
54
+ |---|---|---|---|
55
+ | Easy | 5 | Misspelled keywords, missing FROM, = NULL vs IS NULL | ~0.75–0.90 |
56
+ | Medium | 5 | SELECT *, missing indexes, correlated subqueries, unbounded queries | ~0.40–0.60 |
57
+ | Hard | 5 | SQL injection, privilege escalation, PII leakage, self-join optimization | ~0.20–0.40 |
58
 
59
+ Task data: `tasks/easy_tasks.json`, `tasks/medium_tasks.json`, `tasks/hard_tasks.json`
60
 
61
+ ## Action & Observation Spaces
62
 
63
+ **Action** (`SQLReviewAction`):
64
+ - `action_type`: identify_issue | suggest_fix | approve | request_more_context
65
+ - `issue_category`: syntax | performance | security | logic | style
66
+ - `issue_description`: concise statement of the problem
67
+ - `suggested_fix`: corrected SQL fragment
68
+ - `confidence`: float 0.0–1.0
69
 
70
+ **Observation** (`SQLReviewObservation`):
71
+ - `query`: the full SQL query text
72
+ - `schema_info`: dict of table → column definitions
73
+ - `context`: natural language description of query intent
74
+ - `issues_found_so_far`: previously identified issues this episode
75
+ - `remaining_actions`: steps left before episode ends
76
+ - `difficulty`: easy | medium | hard
77
+ - `feedback`: result of last action
