Context

Re-implements the CAJAL / scientific-paper functionality that was rightly reverted from the core SDK (PR #1611 \u2192 revert #1641) as proper examples, per AGENTS.md.

Files added

  • examples/scientific_writing/scientific_writer.py \u2014 single-agent pattern using a regular Agent + @tool functions (format_latex_section, format_citation). CAJAL-4B HuggingFace model via litellm.
  • examples/scientific_writing/multi_agent_paper.py \u2014 3-agent workflow (Literature Reviewer \u2192 Methodologist \u2192 Writer) via AgentTeam + sequential Tasks.
  • examples/scientific_writing/agents.yaml \u2014 YAML parity for the multi-agent workflow (AGENTS.md \u00a77 3-way rule).

Why this location

AGENTS.md rule How this PR complies
\u00a74.1 Protocol-Driven Core \u2014 core SDK has no heavy implementations All code is in examples/, zero changes to praisonaiagents/
\u00a74.3 DRY \u2014 don't duplicate Uses existing Agent, AgentTeam, Task, @tool primitives
\u00a74.4 Agent-Centric Design Composes specialised Agents; no custom Agent subclass
\u00a76.1 Tools pattern Domain behaviour lives in @tool functions
\u00a77 CLI/YAML/Python \u2014 3 ways Python + YAML files included

Validation

python3 -m py_compile examples/scientific_writing/*.py  # \u2713 SYNTAX OK
python3 -c 'from scientific_writer import build_scientific_writer; ...'  # \u2713 Agent constructs, tools work

Original PR #1611 placed a 385-line ScientificWriterAgent class inside praisonaiagents/agent/ (core SDK) with a fake 'real agentic test' that did not call the LLM. This replacement satisfies the same use case without any of those AGENTS.md violations.

Summary by CodeRabbit

  • Documentation
    • Added new scientific writing examples demonstrating multi-agent paper generation workflow
    • Included example configurations and implementations for literature review, methodology design, and paper writing tasks

Review Change Stack

…ion)

Re-implements the CAJAL / scientific-paper functionality that was reverted
from the core SDK (PR #1611 / revert #1641) as proper examples per AGENTS.md:

- examples/scientific_writing/scientific_writer.py
  Single-agent pattern: regular Agent + @tool functions, no subclass.
  Uses the CAJAL-4B HuggingFace model via litellm.

- examples/scientific_writing/multi_agent_paper.py
  Multi-agent workflow: Literature Reviewer -> Methodologist -> Writer
  composed with AgentTeam + sequential Tasks (no custom Agent classes).

- examples/scientific_writing/agents.yaml
  YAML parity for the multi-agent workflow (AGENTS.md Β§7 '3-way' rule).

Why this location:
- AGENTS.md Β§4.1: core SDK has no heavy domain implementations.
- AGENTS.md Β§4.4: compose specialised Agents + tools, don't subclass Agent.
- AGENTS.md Β§6.1: domain-specific behaviour belongs in @tool functions.
- Wrapper / praisonai-tools were alternatives; examples/ keeps it
  discoverable and avoids bloating either package.

πŸ“ Walkthrough

Walkthrough

This PR adds three new example files for a scientific paper writing workflow. The changes introduce reusable LaTeX and citation formatting tools, a configurable scientific writer agent, a multi-agent Python orchestration using AgentTeam, and a declarative YAML configuration that mirrors the Python implementation.

Changes

Scientific Writing Workflow Examples

Layer / File(s) Summary
Tool Definitions & Instructions
examples/scientific_writing/scientific_writer.py
Adds format_latex_section() and format_citation() as decorator-based tool functions, plus SCIENTIFIC_INSTRUCTIONS constant defining required paper sections, citation format, and LaTeX usage rules.
Agent Builder
examples/scientific_writing/scientific_writer.py
Adds build_scientific_writer() function that constructs an Agent named "Scientific Writer" with the CAJAL HuggingFace model and registers the two formatting tools.
Python Workflow Orchestration
examples/scientific_writing/multi_agent_paper.py
Defines three specialized Agent instances for literature review (with citation tool), methodology design (with LaTeX tool), and paper writing; provides run(topic: str) -> str that creates ordered Task objects, builds an AgentTeam, and returns the completed paper.
YAML Configuration
examples/scientific_writing/agents.yaml
Declarative workflow config for praisonai framework defining three roles (literature_reviewer, methodology_designer, scientific_writer) with goals, backstories, models, and task descriptions for the same paper-generation pipeline.
Entry Points
examples/scientific_writing/scientific_writer.py, examples/scientific_writing/multi_agent_paper.py
__main__ blocks in both files demonstrate running the scientific writing workflow with example prompts and printing the resulting LaTeX paper.

Code Review

This pull request introduces a multi-agent workflow for scientific writing, providing both YAML and Python implementations. It includes specialized agents for literature review, methodology design, and LaTeX-formatted paper assembly using the CAJAL-4B model. Feedback suggests updating the format_citation tool to use LaTeX formatting instead of Markdown italics to ensure consistency with the overall LaTeX output requirements.


Returns:
One APA-formatted citation string.

The format_citation tool currently returns Markdown-style italics (*venue*). Since the agent is specifically instructed to produce LaTeX-formatted academic papers (as seen in the instructions and the format_latex_section tool), this should be updated to use the LaTeX \\textit{} command for consistency.

    return f"{authors} ({year}). {title}. \\textit{{{venue}}}."

Greptile Summary

This PR re-implements the CAJAL scientific-writing functionality as proper examples (not core SDK), satisfying AGENTS.md rules by placing all code under examples/scientific_writing/ with zero changes to praisonaiagents/. The three files together cover the required Python + YAML 3-way parity.

  • scientific_writer.py: Clean single-agent factory (build_scientific_writer) with two @tool functions; correctly targets the CAJAL-4B HuggingFace checkpoint via litellm.
  • multi_agent_paper.py: 3-agent sequential pipeline using AgentTeam; sequential mode automatically injects each upstream task output as context, so the writer correctly receives both the literature review and methodology.
  • agents.yaml: YAML parity file, but the header comment documents a CLI command (praisonai agents run --file) that does not exist.

Confidence Score: 4/5

Safe to merge with one fix: the YAML run command in the header comment will mislead users into a CLI error.

All three files are example-only additions with no changes to core SDK code. The Python files are functionally sound β€” AgentTeam wires sequential context automatically so the writer agent receives upstream outputs. The one concrete defect is in agents.yaml: the documented run command does not correspond to any real CLI flag and will error for anyone following the instructions.

examples/scientific_writing/agents.yaml β€” the header run command needs to be corrected to match the actual CLI interface.

Important Files Changed

Filename Overview
examples/scientific_writing/agents.yaml New YAML config for the 3-agent scientific writing workflow; the run command in the header comment is incorrect (praisonai agents run --file doesn't exist β€” should be praisonai run).
examples/scientific_writing/multi_agent_paper.py 3-agent pipeline using AgentTeam with sequential execution; has a spurious # noqa: E402 comment on a top-of-file import, and agents are instantiated at module level (benign for an example).
examples/scientific_writing/scientific_writer.py Single-agent LaTeX paper writer using CAJAL-4B via litellm; clean @tool definitions, proper factory function, and a runnable __main__ block β€” no issues found.

P1 Incorrect CLI command in usage comment

The praisonai agents run --file flag does not exist. The praisonai agents run subcommand only accepts --agent and --task flags for inline agent definitions. Running this comment verbatim will produce an error. Based on patterns in examples/yaml/ (e.g., praisonai run workflow_robustness.yaml or praisonai workflow run hybrid-workflow.yaml), the correct invocation for a roles-based YAML is praisonai run examples/scientific_writing/agents.yaml.

P2 The # noqa: E402 suppression is misapplied. E402 flags module-level imports that appear after non-import statements; here the import is at line 13, at the very top of the file and immediately follows the first import β€” there is no non-import code before it to trigger E402. The comment is misleading and should be removed.

@claude You are the FINAL architecture reviewer. If the branch is under MervinPraison/PraisonAI (not a fork), you are able to make modifications to this branch and push directly. SCOPE: Focus ONLY on Python packages (praisonaiagents, praisonai). Do NOT modify praisonai-rust or praisonai-ts. Read ALL comments above from Gemini, Qodo, CodeRabbit, and Copilot carefully before responding.

Phase 1: Review per AGENTS.md

  1. Protocol-driven: check heavy implementations vs core SDK
  2. Backward compatible: ensure zero feature regressions
  3. Performance: no hot-path regressions

Phase 2: FIX Valid Issues
4. For any VALID bugs or architectural flaws found by Gemini, CodeRabbit, Qodo, Copilot, or any other reviewer: implement the fix
5. Push all code fixes directly to THIS branch (do NOT create a new PR)
6. Comment a summary of exact files modified and what you skipped

Phase 3: Final Verdict
7. If all issues are resolved, approve the PR / close the Issue
8. If blocking issues remain, request changes / leave clear action items
