regressGuard AGENTS.md

Project instructions for RegressGuard that define its product requirements, development process, Go technology stack, and source-code layout. A PRD, or product requirements document, is treated as the main source of truth.

In plain words
What is it for?
Use them when choosing work from the PRD, implementing a feature, checking its acceptance criteria, and recording what was learned.
Why use it?
They give a coding agent the project rules and verification steps needed to make changes consistently.

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

regressGuard AGENTS.md 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 yesterday.

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.

Project Source of Truth

Read RegressGuard-PRD.md before making changes.

The PRD is the product, UX, architecture, and delivery tracker. Section 11 is the implementation source of truth.

Required Workflow

  1. Pick a task from Section 11.
  2. Change its status to IN PROGRESS.
  3. Implement only that task's scope.
  4. Verify acceptance criteria.
  5. Record evidence in the PRD or implementation notes.
  6. Move status to DONE only when the Definition of Done is satisfied.
  7. after we features done , create .md document what we have learned why this feature is need . how its used and how it solves problem. this can be used for future reference how product works.

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.
