Greptile SummaryThis PR addresses four wrapper layer gaps: a broken modal sandbox import path, silent sandbox fallback to subprocess, duplicated ~180 lines between
Confidence Score: 3/5Three of the four fixes are safe to merge; the adapter refactor introduces a re.sub backreference bug in _format_template that will crash agent execution for any topic string containing a backslash followed by a digit. The _format_template change passes str(value) directly as the replacement argument to re.sub. Python treats \1–\9 in a re.sub replacement string as backreferences; when the match pattern has no capture groups, this raises re.error: invalid group reference. The previous BaseFrameworkAdapter._format_template used a callback (def _sub(m): ...) which is immune to this. Any user whose topic string contains a backslash followed by a digit — including Windows-style paths — will see a crash at agent-build time. src/praisonai/praisonai/framework_adapters/praisonai_adapter.py — specifically the new _format_template method at lines 60–71.

Deep audit (local GitHub (live)
Prior “conflicts resolved” vs current stateAn earlier merge-readiness scan (~22:04 UTC) reported conflicts in two files; the triage bot then pushed a rebase (~22:05 UTC). After #2062 landed on Current local merge conflict files (1):

|
| #2094 finding | On main today? |
This PR | Overlap |
|---|---|---|---|
1. Modal loader modal_sandbox typo |
Still broken (_registry.py) |
Fixes import → .modal |
Unique — not on main |
| 1b. Silent sandbox downgrade | Still present (sandbox_cli.py) |
sys.exit(2) + guidance |
Unique — not on main |
2. run/arun ~180-line clone |
Still duplicated | Single arun core + run_sync shim |
Unique — not on main; also touched by open #2084 (praisonai_adapter.py) — coordinate before merge |
| 3. Double AgentOps init | Partially fixed by #2062 (stub pass; functional double-init stopped) |
Removes call + deletes method | Partial overlap — behaviour largely on main; PR adds dead-code cleanup |
Merged PRs (no file overlap): #2054 orphaned modules, #2017 lazy-cache, #2079 observability/async base, #2147 scheduler/tool_resolver.
Open wrapper PRs: #2083 shares agents_generator.py; #2084 shares agents_generator.py + praisonai_adapter.py — highest collision risk with this PR.
Verdict
- Not a duplicate — modal + sandbox CLI + adapter DRY fixes are still absent from
mainand remain valid for #2094. - Rebase required — resolve the single
agents_generator.pyhunk (prefer PR deletion over main’s fix: Wrapper layer: inconsistent code-tool safety gates, duplicated AgentOps init, and non-multi-agent-safe audit log #2062 stub). - Do not close as duplicate — cherry-pick sandbox/registry/adapter hunks if fix: Wrapper architecture: framework-adapter migration broken, duplicate persistence stack, and dead tool #2084 wins the adapter race.
- Prior report was never “CLEAN” on GitHub; it was
CONFLICTINGbefore the bot push, then briefly looked resolved until fix: Wrapper layer: inconsistent code-tool safety gates, duplicated AgentOps init, and non-multi-agent-safe audit log #2062 re-conflicted.

…le AgentOps init - Fix modal sandbox import path from non-existent modal_sandbox.py to correct modal.py - Prevent silent fallback to subprocess when requested sandbox type unavailable - Deduplicate ~180 lines between run/arun methods in PraisonAI adapter - Remove duplicate AgentOps initialization that was creating two sessions Fixes #2094
- Fix import path from non-existent ._base to correct .base module
- Restore model resolution for dict-form llm configs (e.g. {model: 'groq/llama3-70b-8192'})
- Restore model-scoped and provider-scoped runtime resolution paths for backward compatibility
- Fix unused loop variable (task_name → _task_name) per Python conventions
- Add error handling for missing task keys with sensible defaults
- Remove unused is_available import in arun method
Co-authored-by: Mervin Praison <MervinPraison@users.noreply.github.com>
The adapter was inheriting from FrameworkAdapter (Protocol) instead of BaseFrameworkAdapter, causing is_available() to return None. This made the framework appear unavailable regardless of actual installation status. Added explicit is_available() implementation that properly checks for praisonaiagents package availability.
- Add resolve() method that returns self (PraisonAI has no variants) - This fixes the AttributeError that was crashing all executions - All other critical issues were already resolved in the rebased code Co-authored-by: Mervin Praison <MervinPraison@users.noreply.github.com>

re.sub string replacement exposes backreference injection
The new _format_template passes str(value) directly as the re.sub replacement string. re.sub treats \1–\9 in a replacement string as backreferences; if value contains any such sequence (e.g. a Windows path like C:\1st_folder or any topic string containing a backslash followed by a digit), Python raises re.error: invalid group reference and the entire agent build fails.
The parent BaseFrameworkAdapter._format_template was immune to this because it used a callback function (def _sub(m): return ...). The fix is to use a lambda instead of a string: re.sub(pattern, lambda _: str(value), formatted).
