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 | $0.00018 | $0.00672 |
| Opus 5 | $0.00009 | $0.00336 |
| Sonnet 5 | $0.00004 | $0.00134 |
| Haiku 4.5 | $0.00002 | $0.00067 |
Grade A, and why
verifying 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 — 117 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Verification
Don't claim something works until you've seen the evidence.
Announce: "I'm using the verifying skill to confirm this works."
The Rule
NO COMPLETION CLAIMS WITHOUT FRESH VERIFICATION
Step 0: Load Project Config
Before running commands, get the configured commands from EC:
ec_search:
query: project config
type: config
area: project
Extract: test_command, lint_command, build_command
If no config: Use sensible defaults but warn:
"No project config found. Using default commands. Consider running @cog-init."
Step 1: Check for Known Gotchas
Search EC for verification issues in this area:
ec_search:
query: verification gotcha
type: learning
Apply any known workarounds or warnings.
The Gate
Before claiming any success:
- Identify - What command proves this claim?
- Run - Execute it fresh, completely
- Read - Full output, check exit code
- Verify - Does output confirm the claim?
- Then claim - Only now state the result
Command Reference
Use the project-configured commands:
| Claim | Command | Fallback |
|---|---|---|
| "Tests pass" | {test_command} |
npm test |
| "Build succeeds" | {build_command} |
npm run build |
| "Types check" | {lint_command} |
npx tsc --noEmit |
| "Lints clean" | {lint_command} |
npm run lint |
Examples
| Claim | Requires | Not Sufficient |
|---|---|---|
| "Tests pass" | Test output showing 0 failures | Previous run, "should pass" |
| "Build succeeds" | Build with exit 0 | Linter passing |
| "Bug fixed" | Test for the bug passes | "I changed the code" |
| "Type-safe" | Type-check with no errors | "Looks right" |
Forbidden Phrases
Without fresh evidence, never say:
- "Should work now"
- "That should fix it"
- "Tests probably pass"
- "I'm confident this works"
The Pattern
NO: "Fixed the bug, tests should pass now"
YES: [Run tests]
"Tests pass: 47/47. Bug fix verified."
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.

verifying is a skill published in the GitHub repository MereWhiplash/engram-cogitator (4 stars, last pushed 2mo ago), licensed MIT. It adds 18 tokens to every session and 672 once invoked, about $0.0001 per session on Opus 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.
