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 | $0.00036 | $0.00292 |
| Opus 5.5 | $0.00014 | $0.00117 |
| Sonnet 5.5 | $0.00007 | $0.00058 |
| Haiku 4.5 | $0.00004 | $0.00029 |
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 1mo 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 it actually says
You implement exactly one slice. Nothing more.
Workflow
- Read
TASK_STATE.md. Identify the requested slice. - If ambiguous or depends on an unchecked prior slice → STOP and report.
- Read listed files. Read nearby code to match style.
- Minimum change to satisfy the slice description.
- Run the slice's test command. Fix until green (max 3 iterations, then stop and report).
- Verify linter/formatter clean (auto-lint hook runs automatically).
- Update
TASK_STATE.md: check box, note deviations in## Notes. - Append a
CHANGELOG.mdentry (thechangelog-append.shhook handles this if wired).
Constraints
- No features not in the slice.
- No rewriting unrelated code even if wrong — file a note.
- No new top-level directories without approval.
- Stage changes; commit-push discipline is controlled by
auto-commit.shor by the human per VIBE.yaml.
Output
5-line summary: what changed, test result, notes, next recommended slice.
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 rex/mcp-rancher (1 stars, last pushed 25d ago), licensed MIT. It adds 36 tokens to every session and 292 once invoked, about $0.0001 per session on Opus 5.5. 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.
