ahoy

An install and update checker for the abcd tool in the current repository. It reports the repository type, where the tool is anchored, and whether the command-line installation is a development or fixed release copy.

In plain words
What is it for?
Use it to inspect status, diagnose installation problems, preview changes, install or uninstall abcd, or apply a remote update after confirmation.
Why use it?
It helps explain whether abcd is installed correctly and what gaps or conflicts may need repair, with read-only checks available.

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

ahoy 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.

How it starts

The opening of the file, as written. The whole thing — 250 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/abcd:ahoy install/update detector

Run abcd's install/update engine for the current repo and present the result. Bare invocation and the doctor, dry-run and remote sub-verbs perform zero writes; install, uninstall and remote apply are the three that change something, and each says so before it runs — remote apply is the only one that changes state outside this machine, and it asks before it does.

Read $ARGUMENTS for the sub-verb. No argument, or status, is the bare read-only detection pass below.

Bare — read-only detection

Run:

"${CLAUDE_PLUGIN_ROOT}/abcd" ahoy --json

Then summarise the JSON for the user:

  • folder_kindmanaged-repo, unmanaged-repo, or unmanaged-folder.
  • plugin_root_status and root_sha — where abcd is anchored.
  • signals.install_mode — the PATH-entry install mode: dev (tip build) when the track-latest dogfood shim is installed, pinned for the abcd-owned copy of the verified release binary, empty when there is nothing on PATH yet. Either non-empty value may carry a trailing (shadowed on PATH) when another abcd comes first on PATH. Report it so a dev install — or an entry abcd wrote that is not the one that runs — is never invisible.
  • vintage and staleness — the running binary's build revision (in a source checkout) or pinned version, and whether it is up to date, stale, or of an undeterminable vintage relative to the on-disk reference. Report them so a binary running behind its own source is never silent. The comparison is disk-only — no network.
  • banlist — the two-layer name guard, when the folder is a repo: hook and merge_hook (installed / absent / foreign / unreadable), whether this clone is armed (hooks_path_armed), public_family, and the private layer's state on this machine (private_store, and its shape — private_keyed, private_entries, private_unparsed). Never report a foreign hook as abcd's guard, and never report a committed hook as a running one. Relay reach verbatim: it is the one sentence stating what the private layer does NOT cover, and a paraphrase drops the half that matters.
  • gaps — how many are outstanding, and for each actionable one its title, category, and fix_hint; call out which are required.

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.

ahoy is a command published in the GitHub repository intentdriven/abcd (3 stars, last pushed yesterday), licensed MIT. It adds 41 tokens to every session and 3,174 once invoked, about $0.0002 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 2026-08-31.
