What it does
Fork Ancestry is an agent skill from PlamenTSV/plamen. Trigger Pattern Always (run during recon TASK 0, not breadth) - Inject Into Recon agent only (metabuffer.md enrichment)
Its SKILL.md is about 2.4k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Security, covering Smart contracts. It works with Git. The repository describes itself as: Autonomous Web3 security audit agent for Claude Code. The licence is MIT.
When your agent uses it
- Pattern Always (run during recon TASK 0
- Not breadth) - Inject Into Recon agent only (metabuffer.md enrichment)
Example prompts
- “/fork-ancestry”
Workflow steps
4 steps, taken from the step headings in SKILL.md.
What it can do on your machine
Read from SKILL.md and the folder at commit 795962b. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
Shell commands in SKILL.md call:
gitvault
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Fork Ancestry loads about 2.4k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 914 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

FORK_ANCESTRY Skill
Trigger Pattern: Always (run during recon TASK 0, not breadth) Inject Into: Recon agent only (meta_buffer.md enrichment) Purpose: Detect known parent codebases and inherit their historical vulnerability patterns.
1. Detect Fork Indicators
Grep the codebase for known parent signatures:
| Parent Project | Detection Patterns | Common Forks |
|---|---|---|
| Synthetix | SNX|synthetix|StakingRewards|RewardsDistribution|Issuer | Staking rewards forks |
| Compound | CToken|Comptroller|cToken|comptroller|InterestRateModel | Lending protocol forks |
| Uniswap V2 | UniswapV2|PairFactory|getReserves|MINIMUM_LIQUIDITY | DEX forks |
| Uniswap V3 | UniswapV3|TickMath|SqrtPriceMath|NonfungiblePositionManager | Concentrated liquidity forks |
| Aave | aToken|LendingPool|flashLoan.*initiator|AAVE | Lending forks |
| MasterChef | MasterChef|poolInfo|userInfo|pendingReward|massUpdatePools | Yield farming forks |
| Curve | StableSwap|get_dy|A_PRECISION|get_virtual_price|ramp_A|stop_ramp_A|calc_withdraw_one_coin|remove_liquidity_imbalance|admin_fee|commit_new_fee | Stableswap forks — set STABLESWAP_FORK flag if MEDIUM+ confidence |
| OpenZeppelin | Ownable|AccessControl|Pausable|ERC20Upgradeable | Most projects (check version) |
| Basis/Tomb | Boardroom|Treasury|seigniorage|epoch|TWAP.*peg | Algorithmic stablecoin forks |
| Olympus | OHM|gOHM|staking.*rebase|bond.*discount | Rebase token forks |
| Balancer | BPool|WeightedPool|BVault|flashLoan.*userData | Weighted pool forks |
| Yearn | Vault|Strategy|harvest|totalDebt|debtRatio | Yield vault forks |
Git-based detection (complements code-pattern matching — catches forks that renamed all identifiers).
Skip if REPO_SHAPE: squashed_import in build_status.md — single-commit repos have no meaningful git metadata.
- Parse
.gitmodulesfor submodule URLs pointing to known parent repos - Check
git remote -vfor origin URLs matching known parent organizations (compound-finance, Uniswap, aave, sushiswap, curvefi, yearn, OlympusDAO, balancer) - If a git-URL match is found but NO code-pattern match exists, flag as
GIT_ONLY_FORK— the fork likely renamed all identifiers, which warrants deeper divergence analysis
Output: List of detected parents with confidence level (HIGH: 3+ patterns, MEDIUM: 2 patterns, LOW: 1 pattern, GIT_ONLY: git URL match but no code patterns).
2. Query Known Parent Issues
For each detected parent (confidence MEDIUM or HIGH):
2a. Solodit Search (two queries, run in parallel)
// Query 1: Known high-quality issues
search_solodit_live(
protocol="{parent_name}",
impact=["HIGH", "CRITICAL"],
language="Solidity",
quality_score=3,
sort_by="Quality",
max_results=15
)
// Query 2: Rare/unusual patterns specific to fork divergences
search_solodit_live(
keywords="{parent_name} fork modified divergence",
impact=["HIGH", "MEDIUM"],
language="Solidity",
sort_by="Rarity",
max_results=10
)2b. Tavily Search
tavily_search(query="{parent_name} smart contract vulnerability exploit audit finding 2024 2025 2026")2c. Known Issue Catalog
Compile results into:
| Parent | Known Issue | Severity | Root Cause | Solodit Ref | Applicable to Fork? |
|---|---|---|---|---|---|
| {parent} | {issue title} | {severity} | {brief root cause} | {link/ID} | YES / NO / CHECK |
Applicability criteria:
- YES: Fork retains the vulnerable code path unchanged
- NO: Fork modified the vulnerable code path (document what changed)
- CHECK: Cannot determine without deeper analysis (flag for breadth agent)
2d. Hardcoded Known-Issue Floor (Web Search Fallback)
If Solodit AND Tavily BOTH fail, use this minimum catalog -- check EACH applicable parent.
This floor is keyed on the parent's TYPE (generic mechanism), NOT on any specific protocol name — brand-keyed rows are prohibited (a floor row naming a specific protocol is the confirmed benchmark-contamination vector; see the HARD no-overfit rule). Classify the detected parent (from Section 1) into a type below and check the generic known-issue class; use at most one illustrative brand only in prose, never as the row key.
| Parent Type | Critical Known-Issue Class | Root Cause | Search Keywords |
|---|---|---|---|
| Staking-rewards distributor | Reward-rate manipulation via reward-notification timing | Reward duration reset when a new reward is notified mid-period | staking reward notify duration reset |
| Lending / money-market receipt token | First-depositor exchange-rate manipulation | Empty-market rounding in the exchange-rate calc | lending exchange rate first deposit empty market |
| Lending / money-market liquidation engine | Flash loan + oracle manipulation for unfair liquidation | Spot-price dependency in the liquidation health check | flash loan liquidation oracle manipulation |
| AMM constant-product pool (LP token) | First-LP inflation attack (minimum-liquidity bypass) | LP share rounding at low liquidity | amm minimum liquidity first LP inflation |
| Epoch-based seigniorage / rebasing treasury | Epoch-boundary distribution front-running + stake timing | Discrete epoch distribution creates a race at the boundary | epoch seigniorage boundary timing front-run |
| Epoch-based treasury with operator roles | Epoch-boundary timing + treasury allocation fairness + role privilege scope | Extended epoch model with additional operator roles and cooldown mechanisms | epoch treasury operator role cooldown |
| Yield-farming reward distributor (checkpoint-based) | Reward-rate manipulation via zero-amount deposit + unfair early-user dilution | Checkpoint timing where a zero-amount deposit triggers a reward-rate update | yield farming deposit zero reward rate checkpoint timing |
| Stableswap / invariant-curve AMM | Reentrancy via raw native-token transfer in liquidity removal + read-only reentrancy | Native-token callback fires before state update; view functions read stale state during the callback | stableswap reentrancy remove liquidity read-only |
| AMM vault / batched-swap pool | Flash loan + price-oracle manipulation via pool-balance change | Spot price manipulated within a single transaction via balance change | amm vault flash loan oracle manipulation balance |
| Yield vault (share-based accounting) | Share-price manipulation via strategy-report timing + first depositor | Donation before first deposit inflates price-per-share | vault share price first deposit donation strategy |

Note: This floor lists generic known-issue CLASSES by parent type only — it is minimum coverage, not exhaustive, and NOT a substitute for the live-searched Solodit/Tavily results (2a/2b). Real research typically surfaces several more issues specific to the actual parent.
3. Divergence Analysis
For each detected parent:
3a. Identify What Changed
Compare fork vs parent in security-critical paths:
| Component | Parent Behavior | Fork Behavior | Security Impact |
|---|---|---|---|
| {component} | {original} | {modified or SAME} | {new risk or NONE} |
Focus on:
- Modified access control (added/removed roles, changed modifiers)
- Changed mathematical formulas (fee calculations, exchange rates, reward distribution)
- Parameter semantic verification: When the parent has a mathematical specification, verify that each core parameter carries the same mathematical meaning in the fork — not just the same name and numeric range. Forks may store a raw value where the parent stores a derived form (e.g., raw coefficient vs. coefficient scaled by a function of pool dimensions). Compare the fork's formula usage against the parent's specification to confirm the encoding convention matches.
- Added external dependencies (new oracles, new tokens, new protocols)
- Removed safety checks (validation removed, guard removed)
- Changed state variable types or visibility
3b. New Attack Surface from Divergence
For each modification:
- Does the change introduce a NEW vulnerability not in the parent?
- Does the change REMOVE a parent fix/mitigation?
- Does the change create an INCONSISTENCY with parent's invariants?
