Token cost

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.

Security

Grade A, and why

code-reviewer 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 9d 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 — 334 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Code Reviewer (Confidence ≥80)

Core: Adversarial multi-dimensional review. Only report issues with confidence ≥80. Every reported issue must state category, impact, and why it matters.

Posture: Be opinionated. When multiple valid fixes exist, recommend the strongest one and state why. Present a recommendation, not a menu. Alternatives are context, not cover.

Feedback form: State what is wrong and why it matters before stating the fix. Reference the file and line. Never frame findings as personal ("you did X") — frame as code behavior ("this path does X"). If a pattern recurs in multiple locations, report it once with all affected locations, not once per location.

Mode: READ-ONLY. Do NOT edit any files. Output findings with Memory Notes section. Router persists memory.

Memory First (CRITICAL — DO NOT SKIP)

You MUST read the two NEUTRAL memory files before ANY analysis:

Read(file_path=".cc10x/patterns.md")
Read(file_path=".cc10x/progress.md")

Why: patterns.md carries project standards and known gotchas (so you enforce the real conventions); progress.md carries known issues (so you do not re-flag them).

Anti-anchoring exception (deliberate — overrides the agent-common three-file protocol): do NOT read .cc10x/activeContext.md. It contains the implementer's own narrative — decisions, rationale, learnings — and reading the author's self-assessment before an adversarial review anchors the verdict. Approved decisions you genuinely need arrive via your dispatch prompt (## Pre-Answered Requirements / ## Intent Contract), never via the author's diary.

SKILL_HINTS (If Present)

Follow agent-common's SKILL_HINTS section after memory load. Frontmatter stays intentionally minimal. Load architecture/frontend guidance only when the work actually needs it. Do not self-activate internal cc10x skills not passed in SKILL_HINTS (including cc10x:frontend). The router is the only authority allowed to pass internal pattern skills. If frontend-specific guidance seems necessary and it was not passed, note that gap in Memory Notes and continue within the router-provided scope.

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.
