seed-gates

seed-gates is a skill for Claude Code from alicicek/tale-mode. It costs 85 tokens per session (873 once invoked), scanned A, original, MIT.

A repository-scanning guide that suggests which checks should be placed in tale-mode's gate configuration. It examines package scripts, continuous-integration workflows, and other project manifests, but does not change the configuration.

In plain words
What is it for?
Use it to choose safe, finishing commands such as linting, type checks, formatting checks, tests, or builds for tale-mode's turn-end checks.
Why use it?
It helps identify the checks that define whether a project is passing without relying on guesses. Suggestions remain for the user to review before anything is trusted or enabled.

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

seed-gates 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 9d 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 — 66 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Seed the committed gates (suggest-only)

Help the user pick the gates for a committed .claude/tale-mode.json — the config tale-mode's Stop hook enforces during a kickoff phase (once the user trusts its content-hash; see the trust skill). Your output is a suggestion the user reviews — never silently write the config, and never touch the trust store.

1. Inventory candidates mechanically — don't guess from memory

Read the repo's own definition of "green":

  • every package.json → the scripts block (root first; workspaces if a monorepo)
  • CI workflows → .github/workflows/*.yml (or the host's equivalent) — the commands CI actually runs are the strongest signal of what "passing" means here
  • other manifests as present: Makefile, pyproject.toml/tox.ini, Cargo.toml, go.mod (→ go test ./...), a repo-local tests/ runner script

2. Filter hard — a gate runs at EVERY turn-end during a phase

Keep only commands that are hermetic and terminating:

  • ✅ local + deterministic: typecheck (tsc --noEmit), lint, format-check, unit tests, a build that's reasonably fast, a repo-local test script
  • ❌ anything that doesn't terminate: dev, start, serve, --watch
  • ❌ anything non-hermetic: network calls, fresh dependency installs, deploy/publish/release, E2E needing a live server or credentials, destructive/generative steps (db migrations, codegen that rewrites files — a gate must be read-only/idempotent, it runs repeatedly)
  • ❌ anything slow enough to hurt: the default per-gate timeout is 120s (TALE_CHECK_TIMEOUT); a 10-minute suite belongs in CI, not a turn-end gate
  • Each gate runs as ONE shell script — a multi-line JSON string is allowed (it executes as a single script, not split per line), but prefer one command per gate for readable failure output.

3. Verify each candidate by RUNNING it, then present

Run every surviving candidate once from the repo root and record its exit code. A suggested gate that can't run (missing dep, wrong path) — or that always fails — is worse than none: it would trap the loop, and the user would "fix" it by weakening the config. Drop or flag anything that isn't green on the current tree, and say why.

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.

seed-gates is a skill published in the GitHub repository alicicek/tale-mode (36 stars, last pushed 2mo ago), licensed MIT. It adds 85 tokens to every session and 873 once invoked, about $0.0004 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.
