codacy

A set of rules for how an AI coding agent should work with Codacy, a service that analyses code for quality problems.

In plain words
What is it for?
Use it when editing files in a workspace connected to Codacy, especially when each successful edit must trigger an analysis.
Why use it?
It makes code analysis part of the editing process, so changed files are checked immediately and discovered issues can be addressed.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

codacy 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.

Codacy Rules

Configuration for AI behavior when interacting with Codacy's MCP Server

CRITICAL: After ANY successful edit_file or reapply operation

  • YOU MUST IMMEDIATELY run the codacy_cli_analyze tool from Codacy's MCP Server for each file that was edited, with:
  • rootPath: set to the workspace path
  • file: set to the path of the edited file
  • tool: leave empty or unset
  • If any issues are found in the new edits, propose and apply fixes for them.
  • NOTE: Failure to follow this rule is considered a critical error.

After every response

  • If you made any file edits in this conversation, verify you ran codacy_cli_analyze tool from Codacy's MCP Server

When there are no Codacy MCP Server tools available, or the MCP Server is not reachable

Trying to call a tool that needs a rootPath as a parameter

  • Always use the standard, non-URL-encoded file system path

CRITICAL: Dependencies and Security Checks

  • IMMEDIATELY after ANY of these actions:
  • Running npm/yarn/pnpm install
  • Adding dependencies to package.json
  • Adding requirements to requirements.txt
  • Adding dependencies to pom.xml
  • Adding dependencies to build.gradle
  • Any other package manager operations
  • You MUST run the codacy_cli_analyze tool with:
  • rootPath: set to the workspace path
  • tool: set to "trivy"
  • file: leave empty or unset
  • If any vulnerabilities are found because of the newly added packages:
  • Stop all other operations
  • Propose and apply fixes for the security issues
  • Only continue with the original task after security issues are resolved
  • EXAMPLE:
  • After: npm install react-markdown
  • Do: Run codacy_cli_analyze with trivy
  • Before: Continuing with any other tasks

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.
