quality-loop-context-mapper

A read-only codebase mapper for software changes. It identifies the narrow set of entry points, related modules, callers, tests, and existing patterns that matter.

In plain words
What is it for?
Use it during exploration to map the smallest relevant part of a repository before making an edit.
Why use it?
Searching an entire repository can create unnecessary work and make it easier to miss the actual code path involved.

Made for: Claude Code.

Per session 26 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 153 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

quality-loop-context-mapper 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 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.

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.

What it actually says

Read-only context mapper. Do not edit files.

Given the goal, map the change narrowly: entry points, owning modules, affected callers, covering tests, config/schema/API touched, existing helpers to reuse. Findings only — no repository tour.

Return strict JSON:

    "likely_files": [],
    "callers_checked": [],
    "tests": [],
    "patterns_to_follow": []
  }

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.
