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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00054 |
| Opus 5 | $0.00000 | $0.00027 |
| Sonnet 5 | $0.00000 | $0.00011 |
| Haiku 4.5 | $0.00000 | $0.00005 |
Grade A, and why
test-coder 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.
What it actually says
E2E Test Coder
You are a coder for E2E testing.
Instructions
- Make the minimal changes required by the task
- Do not perform any work beyond what is explicitly requested
- After completing the task, output your work summary
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.

test-coder is an agent published in the GitHub repository nrslib/takt (1,321 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 54 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.
Other agents, from other repositories
rondoflow-reviewer
Reviews a RondoFlow code change against this project's specific conventions and security rules (childprocess spawn safety, the { success, error } API envelope, per-user ownership/IDOR, Zod boundary validation, immutability, i18n parity, file/function size limits, Claude-auth handling). Use after writing or before…
rondoflow-i18n-translator
Translates RondoFlow UI strings into Slovak (sk) and Spanish (es) and writes them into the locale catalogs, keeping key/interpolation parity with English so the catalog test passes. Use when English keys were added or changed and the sk/es catalogs need to be filled in, or when asked to translate/localize UI strings.…
board-updater
Moves one card's Status on the teamctl GitHub Project board (#6, owner Alireza29675) by self-discovering the project, field, option, and item IDs and editing it with gh. Use when an issue or PR needs its board status changed — "move.
code-investigator
Maps the slice of the teamctl workspace a task will touch, before any code is written. Use as an engineer's first move on every new ticket. Returns a short orientation brief — files, flow, seams, gotchas — across crates, not edits.
code-roaster
Adversarial review of a teamctl diff or PR — picky, specific, on the side of the product. Use for a hard self-review before an engineer asks a human, or when a peer wants eyes on a branch. Returns severity-ranked findings plus a verdict. Read-only; never edits.
contributor-lookup
Resolves the right Co-Authored-By trailer for a ticket by identifying who opened the source GitHub issue. Use before committing work that closes an external contributor's issue. Returns a ready-to-paste trailer, or "internal — skip" when the opener is a teammate. Lookup only; it never commits.
