classmap-target

classmap-target is a skill for Codex from LIXianSenQwQ/classmap-skill. It costs 63 tokens per session (946 once invoked), scanned A, original, MIT.

A code map in CLASSMAP.md that links features, bugs, and behavior changes to the classes, files, modules, and tests most likely to contain them.

In plain words
What is it for?
Use it to locate where a feature belongs, choose where a bug fix should go, plan a refactor, or find the code responsible for a behavior change.
Why use it?
It reduces blind searching across a repository and helps identify the smallest relevant area before coding. The map is checked against the actual code when it may be incomplete or wrong.

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

classmap-target 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 14d 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 — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

classmap-target

Use CLASSMAP.md to choose candidate code, then verify its responsibilities in the current source.

The result should explain where to look first and any boundary that matters to the request. Locating responsible code does not by itself establish a bug's root cause.

Scope

  • Requests limited to location, explanation, analysis, or review are read-only, including the map. Report any drift without repairing it.
  • Continue into implementation only when the user requests it, following the project's normal coding workflow. This skill adds routing guidance, not a separate implementation process.
  • During implementation, synchronize an existing map only under the incremental rule below and within the user's authorized scope.
  • Creating or broadly refreshing a map belongs to classmap-maintain when requested. Do not make it a prerequisite for the current task.

Workflow

  1. Identify the requested behavior and useful clues, such as a feature name, symptom, route, event, or symbol. Distinguish a location-only request from an implementation request.
  2. If the user supplied a specific file or symbol, start there and consult the map as useful. Otherwise, read relevant parts of CLASSMAP.md to select candidates. If the map is missing, briefly say so and use focused search for this task; do not create it.
  3. Read candidate code before presenting a recommendation. Verify the paths and responsibilities, following relevant entrypoints or callers where needed. Trust code over the map and state any remaining uncertainty.
  4. If the candidates do not explain the behavior, expand search as described below.
  5. Output a concise, verified routing note. For a location-only request, stop after the recommendation and any verification limits. For implementation, continue with the requested change, then consider a scoped map update.

Search When Needed

An absent map entry is not evidence that the behavior is absent from the project.

Follow relevant entrypoints, callers, and implementations; search within the likely module, then use repository-wide targeted search if the location is still unresolved. Use request clues and code evidence as search terms. Skip a narrower step when there is no useful module or candidate to start from.

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.
