Prompt: Repository Audit Template

Generated: {{date}} {{utc_time}} | Author: mbaetiong Updated: Repository Audit Template alignment (offline-first, error-capture, fence discipline)

Purpose - Drive a portable, offline-first repository audit that inventories files, summarizes the README, and collects light-weight static analysis signals with deterministic outputs suitable for ChatGPT-Codex automation.

Instructions - Guardrails: - Treat the repository as untrusted input; do not make outbound network calls or enable CI/hosted actions. - Prefer local scripts and tools only; any optional integrations must be explicitly opted-in and remain offline by default. - Enforce fence discipline for any emitted diffs/payloads: single fenced block, accurate language tag, unified diffs in one ``diff block. - Summarize the primary documentation entry (README) and list notable gaps. - Inventory all files (skipping .git, venvs, caches). For files <= 5MB, record a SHA-256 for reproducibility. - Prefer structural extraction from Python sources (AST/CST/parso) when feasible; otherwise degrade gracefully. - Highlight high-complexity functions (if measured) and flag unusual patterns or hot-spots for deeper review. - Cross-reference_codexstatus updates—**especially**reports/_codex_status_update-2025-10-05.md—to fold prior gap → risk → resolution guidance into the current run. Carry forward any still-open mitigations. - **Error capture:** On any failure, append a block todocs/reference/codex_questions.md: 

Question for ChatGPT-5 @codex {{TIMESTAMP}}:
While performing [STEP_NUMBER:STEP_DESCRIPTION], encountered the following error:
[ERROR_MESSAGE]
Context: [BRIEF_CONTEXT]
What are the possible causes, and how can this be resolved while preserving intended functionality?
Output expectations - JSON:reports/audit.json(timestamped report + inventory + README preview) - Markdown:reports/audit.md(human-friendly summary) - Prompt copy:reports/prompt_copy.md(exact prompt used for the run) - Gap/Risk tracker:reports/gap_risk_resolution.md(table mirroring status-update guidance with containment steps) - Logs (optional):.codex/errors.ndjson` (newline-delimited errors, if any)

Notes - Keep runs deterministic (e.g., export PYTHONHASHSEED=0); prefer stable directory traversal order. - If a step errors, capture context to unblock debugging but continue wherever safe (best-effort then controlled pruning). - Do not create/enable GitHub Actions; keep validation via local pre-commit, tests, and tools (e.g., tools/validate_fences.py if present).

Audit-First Workflow Integration

  • Operate on the most active local branch; document justification in reports/branch_analysis.md.
  • Each run selects three Menu items and delivers 1–3 atomic diffs with supporting docs/tests.
  • Maintain offline cadence: rely on local scripts, pre-commit, pytest/nox, and tools/validate_fences.py.
  • Update artefacts after each run: reports/*.md, CHANGELOG.md, docs/troubleshooting/open_questions.md, and docs/reference/codex_questions.md for any captured failures.
  • Consult reports/report_templates.md for reusable placeholders when updating artefacts.
  1. Repo map
  2. Fix folder
  3. Quality gates
  4. Security
  5. Observability
  6. Performance
  7. Docs polish
  8. Self-management

Document chosen and upcoming items in docs/troubleshooting/open_questions.md.

Asset-driven Menu Playbooks

Repo map & quick wins — use tree output + docs/troubleshooting/open_questions.md

  • Run a shallow repository walk to refresh the structural map: 
    tree -a -L 3 > reports/repo_tree_snapshot.txt
    This keeps the snapshot under reports/ so the map can be diffed between runs.
  • Cross-reference the snapshot with the existing backlog in docs/troubleshooting/open_questions.md to identify "quick win" candidates. Annotate the relevant bullet(s) directly in reports/repo_map.md, linking each entry back to the corresponding section in docs/troubleshooting/open_questions.md for traceability.
  • Record any newly discovered gaps in docs/troubleshooting/open_questions.md using the existing Gap → Risk → Resolution scaffold so that subsequent runs inherit an updated priority list.

Fix folder — single diff + nox_sessions + pre-commit

  • Treat patches/pending/ as the canonical Fix folder. Draft the change as a single fenced unified diff (one patch file per fix) and store it there with a timestamped filename, e.g. patches/pending/$(date +%Y-%m-%d)_fix.patch.
  • Before finalizing the diff, run the targeted formatting and lint hooks locally: 
    pre-commit run --files <changed_files>
  • Exercise the full test gate that mirrors automation expectations: 
    nox -s tests
    Use nox_sessions/ helpers if an individual session needs to be invoked directly. Capture the command outputs and reference them in the accompanying changelog or status update entry.

Security sweep — Semgrep rule IDs → mitigations aligned with ops/threat_model

  • Execute the security-specific Semgrep suite and preserve the rule identifiers in the findings log: 
    semgrep --config semgrep_rules/python-security.yaml --json > reports/security_semgrep.json
  • Prioritize remediation by mapping each finding to STRIDE categories using ops/threat_model/STRIDE.md. Summaries should note the Semgrep rule ID, affected file, STRIDE classification, and recommended mitigation.
  • Convert prioritized mitigations into actionable patches (either immediate diffs under patches/pending/ or tracked follow-ups in docs/troubleshooting/open_questions.md). Reference the relevant threat model section in every mitigation note so the operational context is explicit.

Execution cadence

  1. Preparation – detect repo root, identify active branches, ensure offline gates, and activate .venv if needed.
  2. Search & Mapping – refresh reports/repo_map.md and reports/branch_analysis.md with new observations.
  3. Best-effort construction – implement improvements aligned with the selected Menu items.
  4. Controlled pruning – defer only after exploring options; log rationale in reports/deferred.md.
  5. Finalization – produce reviewable diffs, run local gates, and update changelog/open questions.

Gap → Risk → Resolution register

  • Begin with the latest _codex status signal (reports/_codex_status_update-2025-10-05.md) to seed known gaps and residual risks.
  • For every new observation, document:
  • Gap – the concrete missing artifact or behaviour (file, flag, test, doc entry).
  • Risk – production or reproducibility impact if the gap remains.
  • Containment/Resolution – the minimal patch, guardrail, or operational runbook that neutralises the risk.
  • Update reports/gap_risk_resolution.md using a stable table ordering (capability, gap, risk, containment, owner/next step).
  • When a containment ships, annotate with commit SHA or artefact link and mirror the closure in docs/troubleshooting/open_questions.md.

Gap/Risk/Resolution table scaffold

| Capability | Gap | Risk | Containment / Resolution | Source (status update / commit) | Status |
| --- | --- | --- | --- | --- | --- |
| Tokenization | {{gap}} | {{risk}} | {{containment}} | `reports/_codex_status_update-2025-10-05.md` §{{section}} | {{status}} |
- Use Markdown links for source references when possible (e.g., commit URLs, report anchors). - Keep status values constrained to open, in-progress, or closed for deterministic parsing.

Codex-ready Task Sequence

The following section outlines a robust, phased execution plan for ChatGPT @codex to iteratively implement the missing and incomplete features identified in the status audit for the _codex_ repository (dated 2025-10-05). Each numbered phase comprises fine-grained sub-steps and enforces best-effort construction before any pruning decisions. An error capture block template is provided to guide structured reporting of any failures encountered during execution. In keeping with the repository’s policy, all work must run solely within the Codex environment (no cost-incurring GitHub Actions, no external workflows). Seeds, deterministic settings and environmental captures should be honored to maximize reproducibility.

🔁 Execution Phases

Phase 1 – Preparation

  1. Set up a dedicated working directory (e.g. codex_workdir) separate from the main repository to avoid accidental modifications to untracked files. Initialize a Python virtual environment with the same dependencies declared in pyproject.toml; install extras (ml, logging, dev) to access optional features like WandB/MLflow. Document the exact versions in a requirements/lock.txt file.
  2. Clone the current repository state locally (checkout main and any feature branches flagged in the audit). This clone must remain offline; avoid pushing any commits.
  3. Copy the README and documentation files into a temporary staging area for parsing. Extract all code blocks, commands and TODO markers to form an initial change backlog.
  4. Capture the baseline environment: Python version, OS details, GPU/CPU availability, and random seeds. Persist these details in reproducibility.md.

Phase 2 – Search & Mapping

  1. Enumerate all modules under src/codex_ml and analysis. Build an index mapping each capability (e.g. tokenization, training engine, evaluation) to the corresponding files/classes/functions. Use dynamic imports where possible to confirm loadability.
  2. Scan for stubs or placeholders such as TODO, pass, or NotImplementedError and associate them with the capability index. Log these in a machine-readable capability_map.json.
  3. Review configuration files (pyproject.toml, hydra configs, .env.example) to determine existing hooks for CLI entry points, plugin registries and training defaults.
  4. Identify all available metrics, trainers and dataset plugins by introspecting the registry patterns defined in codex_ml/plugins/registries.py and verifying that the entry points resolve correctly.

Phase 3 – Best-Effort Construction

  1. Tokenization – If a fast tokenizer is missing, implement an adapter around transformers.AutoTokenizer with fallback to WhitespaceTokenizer. Write unit tests ensuring encode/decode equivalence and deterministic padding/truncation for identical inputs.
  2. Logging & Monitoring – Add guarded initialization for MLflow and Weights&Biases. Detect offline/online mode based on environment variables; ensure wandb.init(mode="disabled") for offline runs. Use psutil and pynvml to record CPU/GPU metrics every n steps. Wrap calls in try/except to gracefully handle missing packages.
  3. Configuration Management – Integrate Hydra with YAML defaults. Add a configs/base/default.yaml capturing typical training parameters (model name, tokenizer alias, dataset path, logging toggles). Provide CLI override via --config-name and document usage in the README.
  4. Checkpointing & Resume – Implement checkpoint saving within the training loop, storing model weights, optimizer state, scheduler and RNG seeds. Add retention policy to keep the best k checkpoints and automatically resume from the latest when --resume is supplied.
  5. Internal CI/Test – Extend existing pytest suite with tests covering tokenization, configuration parsing, checkpoint resume, metric logging and plugin registry loading. Define a nox session that runs ruff, black, pytest and pip-audit locally.
  6. After implementing each feature, update documentation (docs/) and ensure the README reflects new commands and flags. All code must conform to the formatting and type-checking rules specified in .pre-commit-config.yaml.

Phase 4 – Controlled Pruning

  1. For capabilities that cannot be fully implemented (e.g. distributed training across multiple GPUs, external moderation APIs, advanced RL algorithms), document clear pruning rationale: lack of open-source implementation, excessive complexity relative to timeline, or missing dependencies.
  2. Remove unused or non-functional stubs to avoid confusion, replacing them with informative comments referencing the audit and deferral plan. Update capability_map.json accordingly.
  3. Provide a migration path for future contributions (e.g. specify where to plug in a reinforcement-learning agent once available).

Phase 5 – Error Capture

Whenever any step encounters an error or unexpected behaviour, create an error report block using the template below and append it to docs/troubleshooting/error_log.md. Do not silently fail.

Question for ChatGPT @codex {{timestamp}}:
While performing [STEP_NUMBER:STEP_DESCRIPTION], encountered the following error:
[ERROR_MESSAGE]
Context: [BRIEF_CONTEXT]
What are the possible causes, and how can this be resolved while preserving intended functionality?

Phase 6 – Finalization

  1. Generate a comprehensive CHANGELOG.md summarizing all modifications, tests added, configuration files introduced, and pruning decisions. Reference the audit report and include links to relevant code sections.
  2. Update reproducibility.md with final seed settings, environment details, and any deviations from the baseline state captured in Phase 1.
  3. Ensure all new or modified Python files pass pytest, ruff, mypy and security scans (bandit, semgrep). The final state must be committed locally but not pushed upstream.
  4. Prepare a summary report highlighting the implemented capabilities, deferred items, and recommended next steps. This report will serve as input for future iterations.

📋 Example Suggested Task Prompts

Below are example prompts tailored for ChatGPT @codex to act upon specific gaps from the audit. Each prompt instructs Codex to perform work across the above phases.

Example 1 – Logging & Monitoring Integration

Implement logging and monitoring in the `_codex_` training engine. Start by inspecting `src/codex_ml/training/__init__.py` to identify where training loops occur. Integrate MLflow and W&B logging guarded by environment checks, ensuring offline compatibility. Add system metrics collection using `psutil` and `pynvml`, recording CPU/GPU utilization at configurable intervals. Update configuration defaults and write unit tests to validate that metrics are recorded when optional dependencies are present and that training does not crash when they are absent. Document the new logging options in the README and update the quickstart guide.

Example 2 – Hydra Configuration Defaults

Add Hydra configuration management to `_codex_`. Create a `configs` directory with a `default.yaml` capturing the core training parameters (model name, tokenizer alias, dataset path, batch size, learning rate, logging toggles). Modify the CLI entry points in `pyproject.toml` to accept `--config-name` and `--multirun` flags. Refactor `src/codex_ml/pipeline.py` and `src/codex_ml/training/__init__.py` to parse Hydra configs and merge them with CLI overrides. Provide example configuration files and update documentation. Write tests to ensure that Hydra correctly overrides parameters and that invalid configurations raise informative errors.

Example 3 – Checkpointing & Resume Capability

Implement robust checkpointing and resume functionality in the training engine. Modify the training loop so that after every epoch it saves the model weights, optimizer state, scheduler state and RNG seeds to a checkpoint directory. Include a retention policy that keeps only the top `k` checkpoints based on validation loss. Add a `--resume` flag to the CLI that resumes training from the most recent checkpoint. Provide unit tests that simulate interruption and verify that resumed training continues from the same epoch and achieves consistent results. Document how to use checkpointing in the README and ensure the feature complies with the reproducibility guidelines.

🛠️ Example Script

The following Python script outlines an executable workflow to realize the above tasks. It can be run from the root of the cloned repository and should be adapted as necessary.

#!/usr/bin/env python3
"""
codex_upgrade.py – orchestrates the phased improvement of `_codex_`.

This script performs preparatory setup, scans for stubs, implements logging, configuration and checkpointing features, and records errors in a structured manner. It must be run offline and will not trigger any remote workflows.

This script is illustrative; the actual implementation must expand the main() function to call modules that perform the integration tasks described in the Example Task Prompts. Each phase should append to the CHANGELOG.md and update documentation accordingly.
