dev-skills AGENTS.md

dev-skills AGENTS.md is an instructions file for Codex, OpenCode from sungurerdim/dev-skills. It costs 1,043 tokens per session, scanned A, original, MIT.

A repository instruction guide for coding agents working on the dev-skills project. It documents commands, conventions, installation options, and project-specific pitfalls.

In plain words
What is it for?
Use it to run the quality check, install or update the skills, check installed copies for drift, and follow the project's commit rules.
Why use it?
It gives agents the project knowledge that cannot be safely inferred from the source files alone.

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

dev-skills AGENTS.md 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 today.

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 — 58 lines — stays where its author put it; the contents beside it link to each section on GitHub.

AGENTS.md

Instructions for any coding agent working on this repository. CLAUDE.md holds the same essentials plus a Claude-Code-specific blueprint profile; nothing here needs to be read twice.

dev-skills is a catalog of 30 Agent Skills — pure markdown, zero runtime dependencies. The only executable code is install.sh (+ its install.cmd Windows launcher), scripts/*.sh, evals/tasks/*/*.sh, and ds-brief/assets/verify-brief.py. Shared references live in core/ and are linked from skills as ../core/<file>.md; the installer ships core/ on every install.

Commands

Task Command
Run the quality gate (do this before every commit) bash scripts/quality.sh
Make the gate run on every commit bash scripts/quality.sh --install-hook
Gate red Fix what it names, re-run, then commit — the hook is never bypassed
Install the skills into a host ./install.sh (or --target <dir>, --project <dir>, --skills a,b)
Install for a Claude-5 host with an always-on rules layer ./install.sh --profile lean — strips the portable-only-marked blocks at install time; repo files always keep the full portable text
Install for Claude Code specifically ./install.sh --profile claude — lean plus one Claude-only sentence injected into ds-ship's delegation step (delegates run as forked subagents); the repo file stays host-neutral
Check an installed copy for drift ./install.sh --check (profile-aware — reads the profile from the version stamp)
See installed vs repo vs upstream at a glance ./install.sh --status — read-only
Update an existing install ./install.sh --updategit pull --ff-only + re-install with the stamped profile; never merges on your behalf

The gate needs bash, python3, shellcheck, and typos. A missing tool fails the run loudly and names what went unverified — never treat a skipped check as a passing one. There is no CI; this gate is the only enforcement, by design.

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.
