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 | $0.00043 | $0.00390 |
| Opus 5.5 | $0.00017 | $0.00156 |
| Sonnet 5.5 | $0.00009 | $0.00078 |
| Haiku 4.5 | $0.00004 | $0.00039 |
Grade A, and why
context 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
Context Skill
Load all relevant claude/ knowledge files for a domain area before starting work.
Usage
/context # Load core context (architecture + rules + lessons)
/context api # Load API-specific context
/context database # Load database-specific context
/context auth # Load auth-specific context
/context build # Load build/CI context
/context security # Load security/CVE context
Domain → Files Mapping
Always read:
claude/tasks/lessons.md— accumulated wisdom from past sessionsclaude/architecture.md— system overviewclaude/rules.md— golden rules
Then based on keyword:
| Keyword | Files to read |
|---|---|
build / test / CI / lint |
claude/build.md |
MR / PR / ticket / template |
claude/templates.md |
CVE / security / dependency |
claude/cve-policy.md |

After Loading
Provide a brief summary of the loaded context and ask what task to perform.
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 is a skill published in the GitHub repository brain-bootstrap/claude-code-brain-bootstrap (11 stars, last pushed 5mo ago), licensed MIT. It adds 43 tokens to every session and 390 once invoked, about $0.0002 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.
