MervinPraisonandClaude Opus 5 323b37bdfc fix(review): adopt every documented backend protocol, not just get_response
Review found the Agent(llm=<object>) fix was incomplete, and it was right.
Verified by running it:

    chat_completion-only backend -> self.llm=<object>  custom=False   BUG
    get_response backend         -> self.llm="custom/..." custom=True  ok

llm/protocols.py documents two more backend surfaces besides get_response:
LLMProviderProtocol via chat/achat, and UnifiedLLMProtocol via
chat_completion/achat_completion. A backend implementing either still fell
through to the plain OpenAI branch, where the object became the model
identifier and the turn went to the wrong backend -- the same defect the
branch was added to fix, for a different protocol.

Detection now duck-types across all of them. Five tests, including two
controls: a plain object with no backend method is still NOT adopted, and a
string llm is unaffected.

MervinPraison 00c56a493e Merge branch 'fix/comp-python-gaps' of https://github.com/MervinPraison/PraisonAI into fix/comp-python-gaps 2026-09-07 13:22:38 +01:00
MervinPraisonandClaude Opus 5 4b3449f423 chore(parity): waive the two new tool() guardrail parameters, with an expiry
CI's signatures gate failed on tool().input_guardrails and
tool().output_guardrails: both are new Python parameters with no
TypeScript counterpart.

These waivers are marked NOT an equivalence. Every other reason in
waivers.yaml documents two SDKs reaching the same result by different
routes, validated by running both. These record a real gap instead --
nothing in praisonai-ts resolves the same behaviour. They exist only to
unblock this PR, because porting is a praisonai-ts change and the two
packages do not share a branch.

Both carry expires: 2026-12-07. An expired waiver fails the check, so if
the TypeScript port is forgotten the gate goes red rather than the gap
quietly becoming permanent.

praisonai-triage-agent[bot]andMervin Praison 94da4aa6c6 fix: block model requests by scope depth, not a shared snapshot
no_model_requests() saved and restored the single _allowed boolean, so two
overlapping scopes (or cross-thread scopes) could re-enable requests while
another scope was still open, leaking a real provider call. Track active
scopes with a counter instead: requests stay blocked until every open scope
exits. Adds regression tests for overlapping and globally-allowed cases.

MervinPraisonandClaude Opus 5 0fe844a726 feat: per-tool guardrails
Guardrails were agent-wide: _tool_call_guardrails / _tool_result_guardrails
are fed only from Agent(guardrails=...) and fire for every tool. Approvals
gate calls interactively. Nothing sat between them, so validating one
tool's arguments -- rejecting a send_email whose recipient is off-domain --
meant hand-wrapping the function.

Adds input and output guardrails scoped to a single tool, declared
alongside the approval and trust options a tool already carries. An input
guardrail sees the arguments before the tool runs and may block or rewrite
them; an output guardrail may block or substitute the result. A blocked
call feeds a message back to the model rather than raising at the user.

Built on the existing GuardrailResult and GuardrailChain rather than a
second guardrail system, so there is one vocabulary for a validation
outcome. Ordering relative to the approval gate and the trust fence is
chosen for safety and documented at the call site.

MervinPraisonandClaude Opus 5 b6b0f19cff chore(parity): regenerate tracker for the new Python exports
Merging the three fixes made the tracker stale in a way none of the
individual branches showed: each was regenerated before the others
existed. Records 6 praisonai-ts gaps (GuardrailRetry plus the five
model_harness test-double exports), up from 0.

Recorded rather than avoided. Withholding the exports to keep the count
at zero would game the measurement instead of reporting it; Python is the
source of truth and TypeScript follows in a separate PR, which is exactly
the state this tracker exists to make visible.

MervinPraisonandClaude Opus 5 59369664c4 fix: feed guardrail rejections back into the live conversation
_apply_guardrail_with_retry already retried on validation failure, but it
threw the conversation away: on rejection it built one fresh user message,
prompt + "Note: Previous response failed validation due to: ...", and sent
that alone. The system prompt, retrieved context, tool results and the
rejected answer never reached the retry. Proven against pristine code --
the second request was a single-element message list.

So the missing capability was never retry; it was feedback into the live
conversation. The retry now appends the rejected assistant turn plus the
reason as a user turn and re-calls with the full history, bounded by the
max_guardrail_retries that already existed. No competing setting is added.

Validators signal rejection the way they already could, by returning
(False, reason). GuardrailRetry is added for validators whose check fails
several frames down -- a Pydantic parse, a lookup helper -- whose message
was previously mangled into "Agent guardrail validation error: ...".

The whole-task layer had the same disease: AgentTeam re-ran tasks with the
identical prompt, logging the guardrail reason and dropping it. It now
fills the Task.validation_feedback slot that already existed, so
Process._build_task_context renders it into the re-run. Reuse of existing
wiring, not new wiring.

Two fixes fell out: the retry passed stream=True regardless of agent
config (the sync path logged an ERROR and fell back on every retry), and
GuardrailChain buried the rejection under "Guardrail error: ...".

Regenerates the parity tracker, which records GuardrailRetry as a new
praisonai-ts gap (count 0 -> 1) pending a TypeScript follow-up.

MervinPraisonandClaude Opus 5 f6788b2db7 feat: scriptable test model and a no-network guard
Nothing shipped let a user unit-test an agent offline. The repo's own
pattern is hand-rolled per test -- LLM.__new__(LLM) followed by assigning
twelve private methods -- repeated across three files.

ScriptedModel subclasses the real LLM and replaces only the
provider-facing methods, so system-prompt assembly, tool-schema
serialisation, the tool-execution loop, tool-result messages, streaming
and async all run production code. Replies are real litellm
ModelResponse objects, parsed by the same path as a live response, so the
double cannot drift from reality. It records requests, scripts tool calls,
and raises ScriptExhausted rather than hanging or inventing a reply.

allow_model_requests(False) blocks every real provider call at the 6
litellm request sites and both OpenAI client properties, and names the
offending call site -- which needed a frame walk, since requests are
dispatched through an asyncio loop on a worker thread.

Fixes a bug found while building this: Agent(llm=<model object>) fell
through every branch to the plain OpenAI path, leaving self.llm set to
the object itself and _using_custom_llm False, so every turn went to
OpenAI under a model name that was really a repr(). Passing your own
model did the opposite of what it means.

Both new error types derive from BaseException on purpose: the tool
loop's broad `except Exception` would otherwise turn "your script is one
reply short" into a silent None return.

MervinPraisonandClaude Opus 5 ac9006edc0 fix: never drop an attachment silently
_build_multimodal_prompt matched five image extensions and had no else
branch, so agent.chat(attachments=["report.pdf"]) appended nothing -- no
part, no warning, no error. The model answered from the text prompt alone
and the caller could not tell the file was ignored. A mistyped path
failed just as quietly, as did pathlib.Path attachments, directories,
non-image URLs, non-image data: URIs and video.

Routing moves to praisonaiagents/agent/attachments.py with one invariant:
an attachment either becomes a model-visible content part or produces a
loud signal. The split is on who can act on it, not on severity.

Addressing errors raise AttachmentError (a ValueError subclass, so
existing handlers still catch): the path does not exist, is a directory,
is unreadable, or is not a str/PathLike/dict. These are always caller
mistakes and there is no useful degraded answer -- continuing means the
model confidently discussing a document it never saw. The message names
the path and the cwd, since a relative path resolved from an unexpected
directory is the usual cause.

Capability limits warn and degrade visibly: the file is readable but the
target model cannot ingest that type. A logging.warning names the file,
model and remedy, AND a marker part is injected into the prompt so the
model knows too and can say it answered without the file. A log line
alone would still leave the answer looking complete.

PDF, audio and ~45 text/code extensions are now routed per model
capability via new supports_pdf_input / supports_audio_input /
supports_vision helpers. PDF degrades by local text extraction, labelled
as such. Images are unchanged, byte for byte.

#
# praisonai-agents has ~11,900 tests. Until this gate, CI executed 15 of them:
# one smoke step in test-optimized.yml naming two files. Everything else was

#
# The cost of that showed up as two test modules that could not even be
# IMPORTED -- they referenced symbols moved or replaced months earlier, so 19
# tests silently contributed nothing while still appearing to exist. A failing
# test is loud; a test that never collects is not.
#
# This job does not run the suite. Running all 11,900 on every PR is a real
# decision about Actions compute, and it would go red on arrival because there
# are pre-existing failures nothing has been enforcing. A job that is red the

#
# Collection alone takes ~40s, costs almost nothing, and would have caught both

Harbor Container → `praisonai code -p --output json "TASK" --dangerously-skip-approval`
Notes:
- `--dangerously-skip-approval` registers an always-approve backend on the
approval registry (plus PRAISON_APPROVAL_MODE=auto /
PRAISONAI_TOOL_SAFETY=off) so the assistant runs fully autonomously in the
container. Before that registry wiring existed the flag left every
critical-tool prompt in place and the non-TTY container auto-denied all of
them, so the agent could not run a single shell command while still
exiting 0 -- one cause of the 0.000 scores in #3932.
- `--dangerously-skip-approval` sets PRAISON_APPROVAL_MODE=auto +
PRAISONAI_TOOL_SAFETY=off so the assistant runs fully autonomously in the
container (no approval hang in a non-TTY session).
- The JSON envelope provides token, cost, session, and status metadata while
the real exit status still surfaces install/auth/startup failures.

different agent. ``tools_resolvable`` says whether the names could be rebound,
so a caller is told rather than left to discover it.

dataclasses, not scalars, and rebuilding them faithfully is a separate,
larger piece of work. An agent that relies on a customised grouped config will
round-trip to one carrying that config's *defaults*, not the original. That is

Protocol for a scheduled, off-hot-path memory consolidation pass.
Long-running agents capture memories inline during a turn; over time the
store accretes near-duplicate, never-merged, never-pruned entries, which
degrades recall precision and grows context/token cost. A consolidation
pass runs on a schedule (never on the reply path) to:
- merge / deduplicate near-duplicate memories,
- promote durable, high-value facts into a curated tier,
- prune stale / low-importance entries,
all under a deterministic gate and a **maximum-loss guard** so a bad
rewrite cannot catastrophically wipe existing memory.
Core defines only this contract; the heavy implementation (an LLM
consolidation turn) and its scheduling live in a lifecycle plugin
(``PraisonAI-Plugins``), keeping core protocol-only and lightweight.
Implementations MUST refuse any rewrite that would drop more than
``max_loss_fraction`` of existing entries, returning a
``ConsolidationResult`` with ``rejected=True`` and leaving the store
untouched.
Example:
```python
from praisonaiagents.memory import ConsolidationResult
class MyConsolidator:
def consolidate(self, memory, *, max_loss_fraction=0.25):
before = memory.get_all_memories()
# ... merge/promote/prune to produce `after`, tracking how many
# ORIGINAL entries survive via `retained` ...
result = ConsolidationResult(
entries_before=len(before),
entries_after=len(after),
retained_originals=retained,
)
if result.exceeds_loss(max_loss_fraction):
result.rejected = True
result.reason = "loss guard tripped"
return result # leave store untouched
# ... apply the rewrite concurrency-safely ...
return result

Structured result for a memory consolidation pass.
A consolidation pass runs off the hot path (typically on a schedule) and
merges near-duplicate memories, promotes durable high-value facts into a
curated tier, and prunes stale/low-value entries. This result reports what
the pass did so callers can log, observe, and enforce loss bounds.
The ``rejected`` flag is set when a proposed rewrite would drop more than
the allowed ``max_loss_fraction`` of existing entries; in that case the
consolidator MUST leave the store untouched (a bad rewrite cannot wipe
existing memory).
Loss is measured against *original* entries, not the net entry count. When
a consolidator knows how many original entries survive the rewrite it should
set ``retained_originals``; ``loss_fraction`` is then derived from that so a
destructive equal-size rewrite (every original replaced by a brand-new
entry) still trips the guard. When ``retained_originals`` is left as ``None``
the loss falls back to the net change in entry count.

```python

"""Encrypt session transcripts at rest.
Conversation history lands on disk in plaintext: `sqlite_store.py` and

package imports a cryptography primitive. That rules PraisonAI out anywhere the
transcript is regulated data, which is most places a support or clinical agent
would run.
This wraps ANY session store rather than adding another one, so encryption is a
decision about deployment instead of a fork of the storage layer:

What it does NOT do, stated plainly rather than discovered later:
* **Search cannot see through encryption.** `search()` matches ciphertext, so a
substring query finds nothing. It raises rather than returning a confident
empty list, because "no results" and "search is impossible here" mean opposite
things and the empty list is the more dangerous answer.
* **Only content and metadata are encrypted.** Session ids, roles and timestamps
stay readable, because the store indexes and orders by them. Anyone treating
ids as sensitive needs a different design, not this wrapper.
* **Losing the key loses the transcripts.** There is no recovery path, by
design.

"""Turn an OpenAPI/Swagger spec into callable agent tools.
PraisonAI emits OpenAPI specs in several places (``recipe/serve.py``,
``app/agentos.py``, ``ui/agui``, ``ui/a2a``) and consumed one nowhere, so
pointing an agent at an existing REST API meant hand-writing a function per
endpoint. A whole spec is now one line:
from praisonaiagents.tools.openapi_toolset import OpenAPIToolset
toolset = OpenAPIToolset(spec_url="https://api.example.com/openapi.json",
auth={"type": "bearer", "token": os.environ["API_TOKEN"]})
agent = Agent(name="ops", tools=toolset.get_tools())
There is an existing workaround -- ``MCP("npx -y @ivotoby/openapi-mcp-server
...")`` fronts a spec as an MCP server -- so this is not a capability that was
unreachable. What it costs is an extra process, an npx dependency, and no
reuse of PraisonAI's own tool plumbing. Everything here routes through the
same helpers the MCP tools use, so a generated tool is indistinguishable from
any other to the Agent.
