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 | $0.00023 | $0.00717 |
| Opus 5.5 | $0.00009 | $0.00287 |
| Sonnet 5.5 | $0.00005 | $0.00143 |
| Haiku 4.5 | $0.00002 | $0.00072 |
Grade A, and why
concept-review 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 2mo 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.

Concept Review Skill
Use this skill to keep AI-assisted work from introducing unnecessary concepts, misleading names, or vocabulary drift.
Required Use
Use this skill when:
- A review includes naming, terminology, abstraction, module boundaries, or user-facing concept changes.
- A diff introduces new nouns, categories, layers, services, records, statuses, protocols, or workflow names.
- The user questions whether wording, naming, or abstraction is necessary.
- A task imports, creates, or modifies external/custom skills whose terminology could override project language.
Required Reading
.agents/rules/outcome-boundary.md.agents/skills/README.md.agents/project/README.md.agents/domain/README.md- The files, diff, plan, or skill being reviewed.
Evidence Priority
Resolve terminology against evidence in this order:
- Current user request and Task Brief language.
- Project/domain source-of-truth files and indexed read triggers.
- Existing public contracts, CLI/API names, generated file names, schemas, and module owners.
- Established naming patterns in the same repository.
- External or custom skill terminology, only as a lower-priority method vocabulary.
If existing terminology is already inconsistent, do not use the inconsistency as permission to add another term. Prefer convergence toward the clearest existing source of truth, or apply .agents/rules/decision-gates.md when renaming a stable contract would affect future development.
Concept Noise Categories
Flag these four types of concept noise:
Vocabulary drift: a new word competes with an existing word for the same concept.Pseudo-concept: a new class, layer, workflow name, status, or category wraps an existing action without adding durable meaning.Semantic misdirection: a name implies a lifecycle, orchestration, state machine, authority, or guarantee that the implementation does not provide.Concept pollution: a lower-level module, reusable rule, public contract, or generic skill imports terms that belong to a different layer, one repository, or one product domain.
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.

concept-review is a skill published in the GitHub repository fqmyysjjd/agent-feed (4 stars, last pushed 5mo ago), licensed MIT. It adds 23 tokens to every session and 717 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 2026-08-31.
Other skills, from other repositories
dxkit-action
Read a dxkit report and execute fixes — prioritize findings by severity, plan the fix sequence, run the fix, verify the score moved, re-baseline if appropriate. Supports a SCOPED pass to burn down one category at a time (dependency/BOM vulnerabilities, security, code quality, tests, docs), and a BASELINE-CLEANUP pass…
dxkit-allowlist
Manage the dxkit allowlist over its whole lifecycle — list, inspect, audit (including orphaned entries after a re-baseline), bulk-defer newly published dep-vuln advisories, remove stale entries, prune expired ones, and export Snyk-originated suppressions to a .snyk policy. Use when the user says "review our…
dxkit-checks
Declare and operate custom repo invariants as first-class guardrail gates — a project rule (a "no imports from X" check, an architecture script, a license audit) or the built-in per-language lint gate. Use when the user says "make our lint errors block the PR", "gate our custom check", "add a repo rule to the…
dxkit-pr
Open a pull request with a title + body grounded in the branch's real commits and diff — what changed, features implemented, findings fixed — plus a reviewer checklist and the dxkit guardrail/allowlist/score signals a reviewer needs. Use when the user says "raise a PR", "open a pull request", "create the PR", "write…
unvibe-review
Use when a project, system, document, or workflow feels bloated, over-engineered, tangled, or fragile despite "working," or when rounds of iteration/review have only ever ADDED and never removed — to find what can be cut, unified, or reframed. Any domain (code, writing, research, video, analysis, ops, decks).…
safe-change
Trace, implement, test, and independently review one bounded software change. Use for ordinary feature, bug-fix, or refactor work after the repository is bootstrapped; do not use for broad repository cleanup, production operations, or undefined rewrites.
