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 | $0.00053 | $0.00312 |
| Opus 5 | $0.00026 | $0.00156 |
| Sonnet 5 | $0.00011 | $0.00062 |
| Haiku 4.5 | $0.00005 | $0.00031 |
Grade A, and why
repo-playbook 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 6d 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.
What it actually says
Repo Playbook (auto-distilled)
Executors: if a dispatch brief matches a PATTERN below, follow it and report
PLAYBOOK: PB-<n> applied → pass|fail. If an entry contradicts the current
codebase, do NOT improvise — report PLAYBOOK: PB-<n> stale: <why>.
Never apply anything under QUARANTINE.
Entry format
### PB-<n> · <class-signature>
provenance: T<x> <YYYY-MM> · hits: <k>
WHEN: <conditions matching a task to this class>
DO: <3–10 imperative steps / invariants, order matters>
VERIFY: <the check that proves it worked>
PATTERNS
(none yet — the system writes its first entry after its first [T2]/[T3] success on a recurring class)
QUARANTINE
(entries that caused an acceptance failure — do not apply until the orchestrator revises them)
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.

repo-playbook is a skill published in the GitHub repository alebgl77/tierdecay (1 stars, last pushed 7d ago), licensed MIT. It adds 53 tokens to every session and 312 once invoked, about $0.0003 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 2026-08-31.
Other skills, from other repositories
cline-fix-volatile-msg
Ladder-aware Cline Anthropic caching — verify the rolling read/write ladder on the wire, then add the tools breakpoint and tune TTL. Updated for the 2026-08 AI-SDK monorepo.
aider-1h-ttl
Aider uses 5min TTL by default and works around long pauses with keepalive pings. Wire up the 1h TTL beta instead.
continue-enable-defaults
Continue's prompt caching is opt-in via config and off by default. Flip the default to systemAndTools.
continue-gemini-explicit
Continue's Gemini provider doesn't use the cachedContents API at all. Add explicit caching for sessions over the minimum token threshold.
opencode-bedrock-doc-blocks
OpenCode places cachePoint on Bedrock messages containing DocumentBlocks, which produces a "nothing available to cache" error.
roo-fix-volatile-msg
Ladder-aware Roo Code Anthropic caching — verify the rolling read/write ladder on the wire, then close the real gaps (Vertex 4-block budget, MiniMax path).
