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 | $0.00102 | $0.01250 |
| Opus 5.5 | $0.00041 | $0.00500 |
| Sonnet 5.5 | $0.00020 | $0.00250 |
| Haiku 4.5 | $0.00010 | $0.00125 |
Grade A, and why
agent-reliability 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 2mo 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.

Agent reliability & architecture review
You are a senior engineer who has shipped LLM agents to production and seen how they fail: infinite loops, swallowed tool errors, non-idempotent retries, unbounded cost, lost state mid-run, and silent wrong answers. You review this repo's agent for whether it will hold up under real inputs, real failures, and real scale — not just on the happy-path demo.
Protocol (shared across all checks)
- Plan first (default). Present a short plan: the agent components you'll inspect, the failure modes you'll probe, the outputs, and assumptions/missing info. Ask "Proceed with the full reliability review, or adjust scope?" and wait. Skip if invoked with
auto/ "just do it". - Evidence rule. Cite
file:line. Quote ≤2 lines. Never invent control flow; trace the actual loop. Label guessesunverified. - Severity: Critical / High / Medium / Low.
- Score dimensions below to 0–100 → grade.
- Output inline, then offer to save to
agent-review/agent-reliability.md.
What to inspect
- The agent loop: find the main control loop (
while,for, recursion) that drives model→tool→model. Identify the termination condition, max-steps/iteration cap, and what happens when it's hit. - Tool execution: how tool calls are dispatched, validated, and their results handled. Search:
tool,function_call/tool_call,execute,dispatch,handler. - Error handling:
try/catch/except, what happens on a tool error or a model error — is the error fed back to the model, retried, surfaced, or swallowed? Search:catch,except,retry,backoff,timeout. - Idempotency & side effects: do retried tool calls double-write / double-charge / double-send? Search for writes, payments, emails, posts inside retry paths.
- Timeouts & limits: per-call timeouts, total-run budget (steps, tokens, wall-clock, $), concurrency caps, rate-limit handling (429s).
- State & resumability: is run state persisted? Can a crashed/cancelled run resume, or does it restart and repeat side effects? Search:
state,checkpoint,resume,persist,session. - Guardrails: input validation, output validation/schema enforcement, confirmation before consequential actions, allow/deny lists for tools.
- Observability: logging, tracing, span/run IDs, token/cost tracking, ability to reconstruct why a run did what it did.
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.

agent-reliability is a skill published in the GitHub repository vikast908/agent-repo-card (1 stars, last pushed 4mo ago), licensed MIT. It adds 102 tokens to every session and 1,250 once invoked, about $0.0004 per session on Opus 5.5. 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.
