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.

What it costs to keep this loaded
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 | $0.00031 | $0.01244 |
| Opus 5 | $0.00015 | $0.00622 |
| Sonnet 5 | $0.00006 | $0.00249 |
| Haiku 4.5 | $0.00003 | $0.00124 |
Grade A, and why
token-conservation 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 7d 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.
How it starts
The opening of the file, as written. The whole thing — 106 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Token Conservation Workflow
When To Use
- Run at the start of every session and whenever prompt sizes or tool calls begin to spike.
- Mandatory before launching long-running analyses, wide diffs, or massive context loads.
When NOT To Use
- Context-optimization already handles the scenario
- Simple queries with minimal context

Step 1 – Quota Check (quota-check)
- Record current session duration and weekly usage (from
/statusor notebook). Note the 5-hour rolling cap and weekly cap highlighted in the Claude community notice. - Capture remaining budget and set a max token target for this task.
Step 2 – Context Plan (context-plan)
- Set a discovery read budget BEFORE reading any files. Count each
Readcall and each content-modeGrepas one read. Glob and files-with-matches Grep are free.- Implement from spec/requirements: max 8 reads
- Bug fix at known location: max 5 reads
- Refactor with known scope: max 1 read per file being changed
- Open exploration: max 15 reads
- Read order (most valuable first): spec/requirements, files to modify, imports/interfaces, then stop and start writing.
- When budget is spent: ask the user if more context is needed. Do NOT self-authorize additional reads. Only explicit user approval overrides the budget.
- Prefer
Readwithoffset/limitparams orGreptool over loading whole files. AReadtargeting <50 lines counts as 0.5 reads. Avoidcat/sed/awkvia Bash: Claude Code 2.1.21+ steers toward native file tools (Read, Edit, Write, Grep, Glob). - PDFs (Claude Code 2.1.30+): Use
Readwithpages: "1-5"for targeted PDF reading instead of loading entire documents. Large PDFs (>10 pages) return a lightweight reference when @-mentioned, so use thepagesparameter to read specific sections. Hard limits: 100 pages max, 20MB max per PDF. Exceeding these previously locked sessions permanently (fixed in 2.1.31). - Convert prose instructions into bullet lists before prompting so only essential info hits the model.
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.

token-conservation is a skill published in the GitHub repository athola/claude-night-market (337 stars, last pushed today), licensed MIT. It adds 31 tokens to every session and 1,244 once invoked, about $0.0002 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 2026-09-03.
