AGENTS

A guide to the REPL, a text-based interactive command prompt, and its slash commands in a Rust project.

In plain words
What is it for?
Use it when adding, changing, parsing, documenting, or debugging REPL slash commands.
Why use it?
It shows where commands are defined, parsed, documented, and connected to other parts of the code.

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

AGENTS 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.

OVERVIEW

REPL slash-command surface: parsing, spec registry, help rendering, and a handful of in-crate handlers. Single flat src/lib.rs (~7k lines). Deps: plugins, runtime, serde_json only. Note: tools depends on commands, not the reverse.

lib.rs MAP

Lines Landmark
16–58 Registry types: CommandManifestEntry, CommandSource (Builtin / InternalOnly / FeatureGated), CommandRegistry, SlashCommandSpec, SkillSlashDispatch
60–1047 SLASH_COMMAND_SPECS static table. 120+ entries (help, status, sandbox, compact, model, permissions, clear, cost, resume, config, mcp, memory, init, diff, version, bughunter, commit, pr, issue, ultraplan, teleport, debug-tool-call, export, session, plugin, agents, skills, doctor, plan, review, tasks, theme, vim, voice, chat, ...)
1048–1303 SlashCommand enum (~65 variants + Unknown(String)), SlashCommandParseError, SlashCommand::parse (L1218)
1515–1899 Per-command arg parsers: parse_mcp_command, parse_plugin_command, parse_session_command, etc.
1900–2108 Help/suggestion rendering: render_slash_command_help*, suggest_slash_commands (Levenshtein), category grouping
2109–2682 Result types + handlers: handle_plugins_slash_command, handle_agents/mcp/skills_slash_command(_json), skill dispatch/resolve
3160–5293 Reporting layer: paired text and _json renderers for plugins/agents/skills/mcp reports, skill install/uninstall/create-agent logic, frontmatter parsing, root discovery
5294 handle_slash_command(input, session, compaction) top dispatch. Only Compact and Help execute here; all other variants return to the REPL caller
5403–7183 mod tests (~1780 lines)

ADDING A SLASH COMMAND

  1. Spec. Add a SlashCommandSpec entry to SLASH_COMMAND_SPECS. Set resume_supported honestly.
  2. Enum + parse. Add a variant to SlashCommand. Wire a match arm in SlashCommand::parse. If the command takes arguments, add a dedicated parse_*_command function in the arg-parser block.
  3. Handler. Decide where execution lives:
    • In-crate (like Compact/Help): handle it inside handle_slash_command.
    • Returned to caller: just return the parsed variant. The REPL layer executes it.
  4. Help. Make sure the spec's summary and argument_hint are set so help rendering and suggestion matching pick it up automatically.
  5. Tests. Cover parsing (valid input, bad input, edge cases) in the inline mod tests.

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.

AGENTS is a command published in the GitHub repository ultraworkers/claw-code (195,163 stars, last pushed 16d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 818 tokens. 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.
