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 5.1 | $0.00000 | $0.00006 |
| Opus 5 | $0.00000 | $0.00003 |
| Sonnet 5 | $0.00000 | $0.00001 |
| Haiku 4.5 | $0.00000 | $0.00001 |
Grade A, and why
implementer 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 5d 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.
This is a copy
100% identical to implementer — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

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.

implementer is an agent published in the GitHub repository bharat3645/The-Ideal-Harness (5 stars, last pushed 2d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 6 tokens. A static security scan graded it A with 0 findings. It is 100% identical to implementer, differing in 0 lines, and is treated as a copy.
Other agents, from other repositories
lead
Agent "lead" from enmanuelmag/agent-harness-kit, covering lead agent — @cardor/agent-harness-kit, available research tools, provider delegation guidance, lead agent — @cardor/agent-harness-kit and !! absolute constraint — read before anything else !!.
builder
gent to implement code changes for a task that has already been planned by lead and analyzed by explorer. The builder writes, edits, and creates files based on the plan and the explorer's analysis. Invoke only after the explorer has completed its action. Never invoke without a canonical handoff addressed to builder.
consultant
Agent "consultant" from enmanuelmag/agent-harness-kit, covering consultant agent — @cardor/agent-harness-kit, available research tools, consultant agent — @cardor/agent-harness-kit, !! absolute constraint !! and direct consultation mode — no harness.
explorer
gent to read and map the codebase for a specific task. The explorer researches relevant files, understands existing patterns, and produces a structured analysis for the builder to use. Invoke after the lead has defined a plan and before the builder starts. Never invoke for tasks that require writing or modifying files.
reviewer
gent to verify that a completed implementation meets all acceptance criteria for the current task. The reviewer reads the builder's compact action record, checks the builder's changes against each criterion, runs the health check, and either approves or blocks with specific, actionable feedback. Invoke only after the…
contract-review
Read-only adversarial contract reviewer. Reviews the full contract set against user scope, inventory, playbook rules, evidence feasibility, shortcut risk, and old-harness-style atomic assertion coverage before tasks are trusted.
