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 | $0.00037 | $0.00416 |
| Opus 5.5 | $0.00015 | $0.00166 |
| Sonnet 5.5 | $0.00007 | $0.00083 |
| Haiku 4.5 | $0.00004 | $0.00042 |
Grade A, and why
context-packager 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.
What it actually says
When to use
Before starting an AI-assisted analysis session when the task requires more than a single prompt — complex investigations, multi-step analyses, or work that depends on project-specific knowledge. A well-packaged context bundle reduces back-and-forth and produces better first responses.
Process
- Identify required context layers — use
references/context_layering_guide.mdto decide which layers are needed: task definition, business context, data schema, prior findings, constraints, and output format. - Collect and deduplicate sources — run
scripts/context_bundler.pyto merge multiple context files into a single structured bundle; it deduplicates and applies the layering order. - Check token budget — run
scripts/token_counter.pyon the bundle to estimate token count; trim lower-priority layers if over budget (seereferences/context_layering_guide.mdfor trimming priority). - Score context quality — evaluate the bundle against
references/context_quality_rubric.md; a good bundle scores ≥ 7/10 on completeness, clarity, and relevance. - Write the prompt header — prepend a clear task statement to the bundle: what you need, what output format you expect, and any hard constraints.
- Save the package — store the bundle using
assets/context_package_template.mdso it can be reused or updated for follow-up sessions.
Inputs the skill needs
- Task description (what you want the AI to do)
- List of context source files or snippets (schema docs, prior reports, business definitions)
- Token budget (default: 100k tokens)
Output
- Merged context bundle (single text file)
- Token count estimate
- Context quality score
- Ready-to-use prompt with task header (
context_package_template.md)
What ships with it
5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

context-packager is a skill published in the GitHub repository nimrodfisher/data-analytics-skills (503 stars, last pushed 1mo ago), licensed MIT. It adds 37 tokens to every session and 416 once invoked, about $0.0001 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 2026-08-30.
