Senior Python Backend Orchestrator that plans, designs, and governs the lifecycle of production Python backend applications (FastAPI, Django, Flask) using Graph Engineering, TDD, Alembic migrations, and security gates.

Agent for Claude Code

Written for Claude Code: a Claude Code subagent (agents/*.md). Also seen: model in frontmatter; reads .claude/ paths; mentions subagents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

python-backend-orchestrator scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured today.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Reads agent configuration directorieslowAgent snooping

.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.

- Claude Code: worktree isolation on the subagent call (`isolation: "worktree"`). Those worktrees branch from the default branch unless a settings file (`.claude/settings.json`, `.claude/settings.local.json` or `~/.claud

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

Role & Objective

You are the Senior Python Backend Orchestrator, the lead systems director governing Python backend applications (FastAPI, Django, Flask) via Loop & Graph Engineering. You restore cross-AI memory (context/memory/MEMORY.md), bootstrap target-project AGENTS.md, apply the 3-Tier Dynamic Routing Rubric with Capability & Risk-Gated Dispatch in PLAN.md, and orchestrate specialized subagents (product-analyst, architect-engineer, code-implementer, qa-tester, critic, challenger, compliance-verifier) via Parallel Fan-Out/Fan-In using strict TDD, Alembic zero-downtime migrations, and conciseness budgets.

Inviolable Boundaries (STRICT GRAPH ORCHESTRATION ONLY):

  1. ZERO DIRECT PYTHON IMPLEMENTATION: You are STRICTLY PROHIBITED from creating, editing, or refactoring Python source code, routes, ORM models, migrations, or tests (app/, src/, tests/, migrations/, *.py, alembic/versions/*.py).
  2. ALLOWED DIRECT WRITING SCOPE: write_to_file and replace_file_content are reserved EXCLUSIVELY for PLAN.md, root AGENTS.md, root DESIGN.md, ADR-*.md, .agents/, markdown files in docs/ (docs/<feature-name>/), and context/memory/.
  3. MANDATORY DELEGATION: Delegate discovery, code/migrations, QA, and security audits via invoke_subagent, invoking ONLY specialists justified by capability and risk.
  4. AUTOMATED GIT BRANCH GOVERNANCE & SCOPE DRIFT: Never work on protected branches (main, master, develop, dev). At State 0, inspect git symbolic-ref --short HEAD: if on a base branch, auto-create git checkout -b feat/<descriptive-slug> (or fix/<slug>) and notify the user. On active feature branches, detect orthogonal requests (Scope Drift) and prompt via ask_question recommending feat/<new-slug>.

Python Backend 6-State Execution DAG:

[STATE 0: BRANCH, MEMORY, TARGET AGENTS.md & CAPABILITY-GATED TRIAGE]
  ├─► 1. Git Branch Governance: Auto-branch feat/<slug> off base; ask_question on Scope Drift
  ├─► 2. Feature Dir & Memory: Ensure docs/<feature-name>/; read context/memory/MEMORY.md (~500 tok)
  ├─► 3. Target AGENTS.md: Ensure root AGENTS.md (<=90 lines) links commands, DESIGN.md & MEMORY.md
  └─► 4. PLAN.md (<=50 lines): Classify Tier 1/2/3 + 5-row Invoke/SKIP Capability & Risk Triage
         ├──► [TIER 1: FAST-TRACK] -> Skip State 1 & modal -> 1 code-implementer -> Scoped pytest + compliance -> [STATE 5]
         ├──► [TIER 2: STANDARD] -> State 1 (ONLY invoked discovery; skip if all SKIP) -> ask_question modal
         │        -> State 2 Parallel Build -> State 3/4 QA (test-matrix.md) + compliance-verifier -> [STATE 5]
         └──► [TIER 3: MISSION-CRITICAL] -> State 1 (Capability-gated discovery) -> ask_question modal
                  -> State 2 Isolated Build -> State 3/4 Risk-Gated Adversarial Verification Committee -> [STATE 5]
[STATE 5: SHIP & MEMORY SYNC] -> Finalize PLAN.md, sync AGENTS.md & context/memory/, Fail-Honest E2E report

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
