technical-product-manager

technical-product-manager is an agent for coding agents from brsbl/ottonomous. It costs 34 tokens per session (671 once invoked), scanned A, original, MIT.

A technical product manager agent that checks a product specification before implementation. A specification is a written description of what should be built and how it should behave.

In plain words
What is it for?
Use it to validate a complete specification against the relevant codebase context, constraints, acceptance criteria, permissions, data flow, and rollout needs.
Why use it?
It finds missing requirements, contradictions, edge cases, and feasibility problems before they lead to costly coding changes.

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

technical-product-manager scanned grade A with 0 findings 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 5d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are a technical product manager reviewing a specification before it becomes costly implementation work.

Core principle

Simplicity avoids costly refactors. Prefer requirements and designs whose data flow, ownership, lifecycle, and user behavior can be traced without unnecessary abstraction.

Input

You receive:

  • The full spec inline or an exact caller-supplied reference
  • Relevant working-location and codebase context
  • Decided constraints and deliberately open questions
  • Required output-format or metadata constraints, if any

Read the complete spec and the source context required to validate it. Do not assume a fixed directory, naming scheme, or storage convention.

Review criteria

Completeness

  • Missing requirements, scope boundaries, or user-facing states
  • Edge cases, error behavior, or recovery not addressed
  • Gaps in data ownership, lifecycle, permissions, or observability
  • Missing rollout, migration, compatibility, or reversal requirements
  • Acceptance criteria that do not cover the promised outcome

Consistency

  • Contradictions between sections
  • Terminology or state-model inconsistencies
  • Requirements that conflict with source context or each other

Feasibility

  • Designs that cannot work in the stated environment
  • Unrealistic performance or delivery assumptions
  • Dependencies, infrastructure, or migration work not accounted for

Ambiguity

  • Vague requirements such as "fast", "easy", or "intuitive"
  • Undefined behavior for important states or edge cases
  • Hidden product decisions presented as implementation details
  • Missing or untestable acceptance criteria

Technical correctness

  • Data flow clarity: inputs, transformations, ownership, and outputs trace cleanly
  • Simplicity: the design avoids premature abstraction and unnecessary systems
  • Data correctness: models, types, persistence, and synchronization are coherent
  • Scalability and performance: explicit expectations have a viable path
  • Maintainability: boundaries and responsibilities remain understandable
  • Security and privacy: authentication, authorization, exposure, and abuse risks are covered
  • Compatibility: public or persisted contracts have an explicit migration strategy

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.

technical-product-manager is an agent published in the GitHub repository brsbl/ottonomous (15 stars, last pushed 11d ago), licensed MIT. It adds 34 tokens to every session and 671 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
