generic-research-codebase

A repository-reading skill that maps the code and documents how its parts fit together. A repository is the project folder containing the code, configuration, and documentation.

In plain words
What is it for?
Use it to document the project’s structure, dependencies, routes, rules, resources, tests, and other existing parts.
Why use it?
It helps create a clear description of an unfamiliar codebase without changing the code. This gives developers a shared reference for understanding the project.

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

generic-research-codebase 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 2d 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 — 47 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Research Codebase

Read a repository, map what exists, and produce neutral architecture documentation without changing code.

This skill is a thin loader for the colocated skill.spec.yml. The spec is the source of truth for routes, rules, dependencies, imports, resources, recipes, tests, and trace requirements.

Runtime Contract

  1. Load ./skill.spec.yml from this skill folder before taking task actions.

  2. When the skillspec CLI is available, run:

    skillspec decide ./skill.spec.yml --input='<user task>' --trace-dir "${PWD}/.skillspec/traces"

  3. Strip skill invocation prefixes such as /my-skill, $my-skill, or /rote-shell-spec before passing --input.

  4. Preserve the emitted trace run_dir.

  5. When the CLI is available after a trace exists, run skillspec trace align ./skill.spec.yml --decision-trace <run_dir> and report the alignment status with the trace path.

  6. Follow the selected route, matched rules, forbids, elicitations, dependencies, imports, recipes, and closures from skill.spec.yml.

  7. If the CLI is unavailable, read skill.spec.yml directly and apply its rules manually. Do not expand this loader into a second source of truth.

Quick Commands

skillspec validate ./skill.spec.yml
skillspec imports check ./skill.spec.yml
skillspec test ./skill.spec.yml
skillspec deps check ./skill.spec.yml
skillspec explain ./skill.spec.yml --input='<user task>' --trace-dir "${PWD}/.skillspec/traces"
skillspec trace align ./skill.spec.yml --decision-trace "${PWD}/.skillspec/traces/<run-id>"

Completion Report

When reporting completion, include the selected route, the SkillSpec trace run_dir, the skillspec trace align status (pass, fail, or unproven), key failed or unproven alignment checks, and the concrete execution evidence ids or files.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

generic-research-codebase is a skill published in the GitHub repository modiqo/skillspec (737 stars, last pushed 24d ago), licensed Apache-2.0. It adds 23 tokens to every session and 496 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
