Ripwire Subsystem Handoff
redhat-et/ripwire
Produces a short brief for handing a code subsystem to a teammate or fresh session, using ripwire to rank symbols, expand bodies and surface design docs.
Gives an agent a quick map of a codebase's structure, dependencies, changes and handoffs, and tunes per-project config so the output stays code-first.

codemapGives an agent a quick map of a codebase's structure, dependencies, changes and handoffs, and tunes per-project config so the output stays code-first.
Codemap classifies the intent of your prompt, detects risk, matches relevant skills and tracks your working set through hooks. Its commands show project structure and top files, dependency flow with hub files, changes against the main branch and which files import a given file, so the agent can judge the blast radius before editing. A `codemap skill show` command prints guidance for a matched task such as hub editing, refactoring or testing.
On first use in a repo, or when output is noisy, the agent checks `.codemap/config.json` and, if it is missing or boilerplate, follows the `config-setup` guidance to filter out assets, generated files, fixtures and other non-code directories, then reruns the structure and dependency views. The skill lists when to run each command, such as at the start of any task, when asked where something is, before refactoring or when summarizing a branch, and it supports cross-agent handoffs for resuming work.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 253c8d6. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Codemap loads about 1.8k tokens when it runs. Until then it costs about 94 tokens; SKILL.md has 724 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/codemap/SKILL.md (or your agent's skills folder).Codemap gives you instant architectural context about any codebase. It classifies your intent, detects risk, matches relevant skills, and tracks your working set — all automatically via hooks.
Codemap should also keep its own per-project config healthy. On first use in a repo, or when output is obviously noisy, tune .codemap/config.json before doing deeper analysis so future calls stay code-first instead of asset-first.

redhat-et/ripwire
Produces a short brief for handing a code subsystem to a teammate or fresh session, using ripwire to rank symbols, expand bodies and surface design docs.
cocoindex-io/cocoindex-code
Semantic code search and index management with the ccc CLI: the agent initializes, indexes and queries the project by concept, filtering by language or path.
yamadashy/repomix
Packs a local directory or remote GitHub repository into one AI-friendly file with Repomix, then searches it to explore structure, find patterns and count tokens.
Ruhan-Wang/Harness_Handbook
Generates, refreshes, validates and uses a compact handbook that maps where a change touches in a repository, using the active Codex session and no external LLM API.
Helweg/open-codebase-index
Chooses the right retrieval tool for code questions: compact context for unfamiliar repos, direct lookup for known symbols, call graphs for relationships and grep for exhaustive matches.
Helweg/open-codebase-index
Directs an agent to use a local codebase index for repository orientation, definition lookups, call graphs and semantic search before turning to web lookups.
JordanCoin/codemap
Writes or tunes .codemap/config.json so Codemap output centers on a repository's real source code instead of assets, fixtures and generated files.

Gives an agent a quick map of a codebase's structure, dependencies, changes and handoffs, and tunes per-project config so the output stays code-first. Codemap classifies the intent of your prompt, detects risk, matches relevant skills and tracks your working set through hooks. Its commands show project structure and top files, dependency flow with hub files, changes against the main branch and which files import a given file, so the agent can judge the blast radius before editing.
Codemap fits situations like: getting oriented in an unfamiliar repository before starting a task; checking which files import a file before editing it; summarizing what changed on a branch against main; resuming work handed over from another agent.
Run `npx skills add JordanCoin/codemap --skill codemap -a claude-code`. Or copy the skill folder (.claude/skills/codemap in JordanCoin/codemap) into .claude/skills/codemap in your project. Claude Code loads it when a task matches its description.
Run `npx skills add JordanCoin/codemap --skill codemap -a codex`. Or copy the skill folder (.claude/skills/codemap in JordanCoin/codemap) into .agents/skills/codemap in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add JordanCoin/codemap --skill codemap -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/codemap, .gemini/skills/codemap, .github/skills/codemap and .opencode/skills/codemap in your project.
SKILL.md names no scripts, command-line tools or credentials: Codemap is instructions for the agent only. Our summary lists: The `codemap` CLI installed.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Codemap is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.8k tokens (SKILL.md is roughly 7.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Codemap: Ripwire Subsystem Handoff (redhat-et/ripwire, 2.4k stars), ccc Semantic Code Search (cocoindex-io/cocoindex-code, 2.7k stars), Repomix Codebase Packer (yamadashy/repomix, 29k stars) and Codebase Handbook Builder (Ruhan-Wang/Harness_Handbook, 332 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
