feat: add token budget tracking and enforcement

- Add max_budget and on_budget_exceeded to ExecutionConfig
- Track total cost, tokens, and LLM calls per agent run
- Enforce budget limits with stop/warn/callable actions
- Zero overhead when budget tracking is disabled
- Add BudgetExceededError exception
- Update config serialization to include budget fields

Provides cost control for agent deployments with configurable limits.

-# Migration Guide
-
-This guide documents breaking changes and deprecations in PraisonAI, with migration instructions and timelines.
-
-## Version Strategy
-
-PraisonAI follows [Semantic Versioning](https://semver.org/):
-- **Major versions** (e.g., 2.0.0): Breaking changes, deprecated features removed
-- **Minor versions** (e.g., 1.5.0): New features, deprecations introduced
-- **Patch versions** (e.g., 1.5.1): Bug fixes, no API changes
-
-**Deprecation Timeline:**
-- Features are deprecated in **minor** releases
-- Deprecated features are removed in the **next major** release
-- Deprecation warnings include the removal version
-
-## Current Deprecations (v1.0.0)
-
-### Agent Parameters → Consolidated Config Objects
-
-**Status:** Deprecated in v1.0.0, will be removed in v2.0.0
-
-Old standalone parameters have been consolidated into config objects for better organization and type safety.
-
-#### ❌ Old Way (Deprecated)
-```python
-from praisonaiagents import Agent
-
-agent = Agent(
-    name="coder",
-    allow_code_execution=True,       # ❌ Deprecated
-    code_execution_mode="unsafe",    # ❌ Deprecated  
-    auto_save="my_session",          # ❌ Deprecated
-    rate_limiter=my_limiter,         # ❌ Deprecated
-    allow_delegation=True,           # ❌ Deprecated
-    verification_hooks=[my_hook],    # ❌ Deprecated
-    llm="gpt-4o-mini"               # ❌ Deprecated
-)
-```
-
-#### ✅ New Way (Recommended)
-```python
-from praisonaiagents import Agent, ExecutionConfig, MemoryConfig
-from praisonaiagents.agent.autonomy import AutonomyConfig
-
-agent = Agent(
-    name="coder",
-    model="gpt-4o-mini",  # ✅ Use 'model' instead of 'llm'
-    handoffs=[reviewer_agent],  # ✅ Use 'handoffs' instead of 'allow_delegation'
-    execution=ExecutionConfig(
-        code_execution=True,
-        code_mode="unsafe", 
-        rate_limiter=my_limiter
-    ),
-    memory=MemoryConfig(auto_save="my_session"),
-    autonomy=AutonomyConfig(verification_hooks=[my_hook])
-)
-```
-
-**Migration Steps:**
-1. Replace `llm=` with `model=`
-2. Replace `allow_delegation=True` with `handoffs=[agent_list]`
-3. Group execution-related params into `ExecutionConfig`
-4. Group memory params into `MemoryConfig`
-5. Group autonomy params into `AutonomyConfig`
-
-### Task Parameters
-
-**Status:** Deprecated in v1.0.0, will be removed in v2.0.0
-
-#### Task Callback → on_task_complete
-```python
-# ❌ Old Way
-task = Task(callback=my_function)
-
-# ✅ New Way  
-task = Task(on_task_complete=my_function)
-```
-
-#### Task Guardrail → guardrails
-```python
-# ❌ Old Way
-task = Task(guardrail=my_guardrail)
-
-# ✅ New Way
-task = Task(guardrails=my_guardrail)
-```
-
-### Class Renames
-
-**Status:** Deprecated in v1.0.0, will be removed in v2.0.0
-
-#### AutonomySignal → EscalationSignal
-```python
-# ❌ Old Way
-from praisonaiagents.agent.autonomy import AutonomySignal
-
-# ✅ New Way
-from praisonaiagents.escalation.types import EscalationSignal
-```
-
-### Directory Structure Changes
-
-**Status:** Deprecated in v1.0.0, will be removed in v2.0.0
-
-#### Data Directory Migration
-```bash
-# Old location (deprecated)
-~/.praisonai-data/
-
-# New location (recommended) 
-~/.praisonai/
-
-# Migration command
-praisonai migrate-data
-```
-
-### Process Workflow → Workflow Class
-
-**Status:** Deprecated in v1.0.0, will be removed in v2.0.0
-
-```python
-# ❌ Old Way
-from praisonaiagents import process
-result = process='workflow'
-
-# ✅ New Way
-from praisonaiagents import Workflow
-workflow = Workflow(steps=[...])
-result = workflow.start()
-```
-
-### BotOS Platform Changes
-
-**Status:** Deprecated in v1.0.0, will be removed in v2.0.0
-
-#### BotApprovalBackend → Platform-Specific Approvals
-```python
-# ❌ Old Way
-from praisonai.bots._approval import BotApprovalBackend
-
-# ✅ New Way - Use platform-specific approvals
-from praisonai.bots.approval import SlackApproval, TelegramApproval, DiscordApproval
-```
-
-### LLM Module Changes
-
-**Status:** Deprecated in v1.0.0, will be removed in v2.0.0
-
-#### Embedding Function
-```python
-# ❌ Old Way
-from praisonai.llm import embedding
-result = embedding(text)
-
-# ✅ New Way
-from praisonai import embed
-# or
-from praisonai.capabilities import embed
-result = embed(text)  # Returns EmbeddingResult with metadata
-```
-
-## Previous Versions
-
-### v0.9.x → v1.0.0
-
-No breaking changes. All v0.9.x code continues to work with deprecation warnings.
-
-## Migration Tools
-
-### Automated Migration (Future)
-We're working on automated migration tools:
-
-```bash
-# Check for deprecated usage (Future)
-praisonai check-deprecations
-
-# Auto-migrate code (Future) 
-praisonai migrate --from=1.0 --to=2.0
-```
-
-### Manual Migration Checklist
-
-Before upgrading to v2.0.0:
-
-- [ ] Update Agent constructor parameters to use config objects
-- [ ] Replace `llm=` with `model=`
-- [ ] Update `allow_delegation` to `handoffs`
-- [ ] Update task parameters (`callback` → `on_task_complete`, `guardrail` → `guardrails`)
-- [ ] Replace `AutonomySignal` with `EscalationSignal`
-- [ ] Migrate data directory with `praisonai migrate-data`
-- [ ] Update workflow process to Workflow class
-- [ ] Replace BotApprovalBackend with platform-specific approvals
-- [ ] Update embedding imports
-- [ ] Run tests to ensure functionality
-
-### Testing Your Migration
-
-After migrating:
-
-```bash
-# Run with deprecation warnings as errors to catch any missed items
-python -W error::DeprecationWarning your_script.py
-
-# Or use pytest
-python -m pytest -W error::DeprecationWarning
-```
-
-## Getting Help
-
-- **Documentation:** Check the updated docs for new patterns
-- **Examples:** See `/examples` for updated usage patterns
-- **Community:** Ask questions in GitHub Discussions
-- **Issues:** Report migration problems in GitHub Issues
-
-## Contributing
-
-When adding new deprecations:
-
-1. Use the `@deprecated` decorator from `praisonaiagents.utils.deprecation`
-2. Specify `since` and `removal` versions
-3. Provide clear `alternative` guidance
-4. Update this MIGRATION.md file
-5. Add deprecation to the test suite
-
-Example:
-```python
-from praisonaiagents.utils.deprecation import deprecated
-
-@deprecated(
-    since="1.5.0",
-    removal="2.0.0", 
-    alternative="use new_function() instead",
-    details="The new function provides better error handling"
-)
-def old_function():
-    pass
-```

+```
+
+- **PR** → go to Step 1  
+- **Issue** → go to Step 8  
+
+---
+
+## Step 1 — Fetch PR Metadata
+
+// turbo
+```bash
+cd /Users/praison/praisonai-package && \
+gh pr view <NUMBER> --json title,body,author,state,additions,deletions,changedFiles,headRefName,baseRefName,labels
+```
+
+Record: title, author, branch, file count, +/- lines.
+
+---
+
+## Step 2 — Read the Full Diff
+
+// turbo
+```bash
+cd /Users/praison/praisonai-package && gh pr diff <NUMBER>
+```
+
+If the diff is very large (>500 lines), pipe through `head -500` first, then read remaining chunks.
+
+---
+
+## Step 3 — Review the Diff
+
+For each changed file, evaluate against **PraisonAI engineering principles** (from AGENTS.md):
+
+| Principle | What to Check |
+|-----------|---------------|
+| **Protocol-driven core** | No heavy implementations in `praisonaiagents/` (core SDK) |
+| **Lazy imports** | Optional deps imported inside functions, not at module level |
+| **DRY** | No code duplication; reuse existing abstractions |
+| **Naming conventions** | `add_X()`, `get_X()`, `XConfig`, `XProtocol`, `XAdapter` |
+| **Async-safe** | No blocking I/O in async context; asyncio primitives used |
+| **Multi-agent safe** | No shared mutable global state without locks |
+| **Thread safety** | Double-checked locking for lazy caches; `threading.Lock` for mutables |
+| **Security** | No hardcoded secrets; `hmac.compare_digest` for comparisons; restricted `exec()` |
+| **Backward compat** | Public API changes require deprecation cycle |
+| **Test coverage** | Tests included; TDD pattern; both unit + agentic tests |
+
+**Red flags to catch:**
+- Module-level imports of optional deps (chromadb, litellm, etc.)
+- Hardcoded credentials or `debug=True` in production paths
+- Direct string comparison for secrets (timing attacks)
+- `exec()`/`eval()` without sandbox
+- Shared mutable globals without `threading.Lock`
+- Missing error handling or swallowed exceptions
+
+---
+
+## Step 4 — Checkout and Run Tests Locally
+
+// turbo
+```bash
+cd /Users/praison/praisonai-package && git checkout main && git pull origin main
+```
+
+// turbo
+```bash
+cd /Users/praison/praisonai-package && gh pr checkout <NUMBER>
+```
+
+Run targeted tests for changed files first:
+
+```bash
+cd /Users/praison/praisonai-package/src/praisonai-agents && \
+python -m pytest tests/ -x -q \
+  --ignore=tests/integration/test_whatsapp_web_real.py \
+  --ignore=tests/unit/tools/test_profiles.py \
+  --tb=short 2>&1 | tail -20
+```
+
+For PRs touching security-sensitive code, also run:
+
+```bash
+# Sandbox tests
+python -m pytest tests/unit/tools/test_python_tools_sandbox.py -v
+
+# CWE-78 env injection tests
+python -m pytest src/praisonai/tests/unit/test_cwe78_env_injection.py -v
+
+# Thread-safety tests
+python -m pytest tests/unit/test_thread_safety.py -v
+```
+
+---
+
+## Step 5 — Verify No Regressions
+
+Run the full test suite:
+
+```bash
+cd /Users/praison/praisonai-package/src/praisonai-agents && \
+python -m pytest tests/ -q \
+  --ignore=tests/integration/test_whatsapp_web_real.py \
+  --ignore=tests/unit/tools/test_profiles.py \
+  --tb=no 2>&1 | tail -5
+```
+
+**Acceptable result:** All tests pass, or only pre-existing flaky tests fail (e.g., `test_file_memory.py::test_memory_persistence_across_agent_instances`).
+
+**Unacceptable:** Any NEW failure introduced by the PR.
+
+---
+
+## Step 6 — Approve or Request Changes
+
+**If the PR is good:**
+
+```bash
+cd /Users/praison/praisonai-package && \
+gh pr review <NUMBER> --approve --body "LGTM — reviewed diff, tests pass, follows PraisonAI engineering principles."
+```
+
+**If changes are needed:**
+
+```bash
+cd /Users/praison/praisonai-package && \
+gh pr review <NUMBER> --request-changes --body "Requesting changes: <specific feedback>"
+```
+
+---
+
+## Step 7 — Merge
+
+```bash
+cd /Users/praison/praisonai-package && \
+gh pr merge <NUMBER> --merge --subject "<PR title>"
+```
+
+Verify merge:
+
+// turbo
+```bash
+cd /Users/praison/praisonai-package && gh pr view <NUMBER> --json state,mergedAt
+```
+
+Then return to main:
+
+// turbo
+```bash
+cd /Users/praison/praisonai-package && git checkout main && git pull origin main
+```
+
+---
+
+## Step 8 — Issue Triage (if URL is an Issue)
+
+### 8a. Fetch issue details
+
+// turbo
+```bash
+cd /Users/praison/praisonai-package && \
+gh issue view <NUMBER> --json title,body,author,state,labels,comments
+```
+
+### 8b. Classify severity
+
+| Tier | Criteria | Examples |
+|------|----------|---------|
+| **Tier 1 — Critical** | Security vuln, data loss, crash in hot path | exec() without sandbox, hardcoded secrets, unprotected globals |
+| **Tier 2 — High** | Performance regression, broken feature, wrong output | Duplicate API calls, memory leak, silent failure |
+| **Tier 3 — Medium** | DX issue, missing validation, doc gap | Bad error messages, missing CLI parity, stale docs |
+| **Tier 4 — Low** | Cosmetic, code style, minor refactor | Trailing whitespace, naming inconsistency |
+
+### 8c. Deep analysis (for Tier 1-2)
+
+1. Read ALL relevant source files end-to-end
+2. Trace the code path that the issue describes
+3. Identify root cause with file paths and line numbers
+4. Assess blast radius (what else could be affected)
+5. Determine if the issue is **actually what it claims** (re-classify if needed)
+
+### 8d. Delegate Implementation to GitHub Workflow Agents
+
+> **KEY PHILOSOPHY: We act as the Manager, GitHub Actions execute the Workflow.**
+
+**DO NOT implement the fix yourself locally.** PraisonAI uses autonomous GitHub Action workflows (such as `gemini-issue-review.yml` and `claude.yml`) to automatically resolve issues and create PRs. Your job as the local agent is to supervise, analyze gaps, and trigger these cloud agents to do the heavy lifting. If there is a gap (e.g. strict test violations), provide detailed relevant information in the PR/Issue and trigger the agents again.
+
+1. Issue the command to trigger the cloud agent on the issue:
+```bash
+cd /Users/praison/praisonai-package && \
+gh issue comment <NUMBER> --body "@gemini please review and fix this issue"
+```
+*(Note: You can use `@claude` or `@gemini` depending on preference or active bots).*
+
+2. Check the GitHub Actions logs (`gh run list`) and wait for the cloud agent to open a Pull Request (`gh pr list`).
+3. Once the cloud bot opens a Pull Request for the issue, return to **Step 1** to review the PR, test the branch locally, and merge it if it passes the checks.
+
+---
+
+## Step 9 — (Skipped) Local PR Creation
+
+> **Note:** As the local agent, you should delegate code fixes to the cloud agents. Only implement code locally and create a PR if the USER explicitly forces you to bypass the cloud agents. If forced, use standard prefixes: `fix:`, `feat:`, `security:`, `refactor:`, `docs:`, `test:`.
+
+---
+
+## Step 10 — Security-Specific Checks
+
+When reviewing security-related PRs, additionally verify:
+
+### Credentials / Secrets
+```bash
+# Check for hardcoded secrets
+grep -rn "secret\|password\|token\|api_key" --include="*.py" <changed-files> | \
+  grep -v "test_\|#\|environ\|getenv\|config"
+```
+
+### Timing Attacks
+```bash
+# Ensure hmac.compare_digest for secret comparisons
+grep -rn "==.*api_key\|==.*secret\|==.*token" --include="*.py" <changed-files>
+```
+
+### Authentication & Workflow Secrets
+When reviewing GitHub Actions workflows (especially ones using cloud actions like `claude-code-action`):
+- **OIDC Validation**: Any workflow using OIDC to authenticate with a cloud provider (e.g. AWS Bedrock for Claude, GCP for Vertex) **MUST** include `id-token: write` in the job's `permissions`. Without it, you will see `Could not fetch an OIDC token` errors.
+- **Valid PAT Usage**: When injecting tokens into workflows via `github_token:`, ensure you use `secrets.GH_TOKEN`. `secrets.PAT_TOKEN` has been known to be invalid or cause `401 Bad credentials` errors when curling GitHub resources. By design, `@copilot` mentions also strictly require `GH_TOKEN`.
+
+### Supply Chain
+```bash
+# Check dependency versions
+pip show <package-name>
+# Check for known compromised versions
+pip install <package>==999 2>&1 | grep "from versions"
+```
+
+### IoC Scanning
+```bash
+# Check for known malicious files
+find $(python -c "import site; print(site.getsitepackages()[0])") -name "<suspicious-file>" 2>/dev/null
+```
+

+## Security & Credentials
+
+- **OIDC Configuration (`id-token: write`)**: Any workflow utilizing the `anthropics/claude-code-action@beta` (or similar actions requiring JWTs for AWS Bedrock/GCP Vertex) MUST define `id-token: write` under the job's `permissions` block. Missing this causes deep, opaque failures like "Could not fetch an OIDC token" paired with `Bad credentials` execution limits.
+- **Valid `github_token` Payload**: Always pass `secrets.GH_TOKEN` into `github_token` inputs rather than `secrets.PAT_TOKEN`, as the latter has historically proven invalid and caused silent 401 exceptions on curl requests behind the scenes.
