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.

SkillSpector: 3 findings, up to medium
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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 | $0.00094 | $0.01677 |
| Opus 5.5 | $0.00038 | $0.00671 |
| Sonnet 5.5 | $0.00019 | $0.00335 |
| Haiku 4.5 | $0.00009 | $0.00168 |
Grade A, and why
context-gather 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 13d 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context Gather
Collect multi-source context before planning or implementation. Searches Serena, Context7, DeepWiki, and web sources, then returns a focused summary. The closing CONTEXT_LOADED: marker is read only by this skill's own Phase 1 scan, which skips a repeat fetch for the same topic in one conversation.
Model choice (behavior change from prior
/context-gatherslash command): this skill's frontmatter carries nomodelfield, so it inherits the harness default rather than the slash command's pinnedopus. Context retrieval is search-and-synthesis work, not deep reasoning. Skill behavior is otherwise unchanged.

Quick Reference
| Field | Value |
|---|---|
| Input | Task description or technology topic (free text) |
| Output | Focused summary with code snippets, architectural insights, and CONTEXT_LOADED: <topic> marker |
| Quality Gate | Summary addresses the stated topic; at least one queried tier reconciled (short-circuit and early-stop exempt); marker line present |
When to Use
Use this skill when:
- Starting a complex task that needs multi-source context before planning or implementation.
- autoplan routes an unfamiliar-topic request here before
research. - You need to pull framework-specific guidance from Context7 alongside project memory.
- Exploring what the memory tiers already record about a topic before committing to an approach.
When to Skip
Skip this skill when:
- A
CONTEXT_LOADED: <topic>marker for the same topic already exists in the current conversation. Do not re-fetch. - The task is trivial and single-step (no external context needed).
- You already have sufficient context from a prior skill invocation or manual research.
- The topic is purely internal to the current file (no cross-cutting concerns).
What ships with it
1 file 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-gather is a skill published in the GitHub repository rjmurillo/ai-agents (49 stars, last pushed today), licensed MIT. It adds 94 tokens to every session and 1,677 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 2026-09-03.
